Replacing a toilet with dismantling the old one: preparation, fastening and connection. Tricks for installing a toilet that will make installation much easier Installing a toilet with your own hands in an apartment

Replacing and installing a toilet in a bathroom does not happen very often. Usually this happens along with the renovation of the entire room and apartment as a whole. Therefore, caring owners rarely take on such a seemingly difficult task. In fact, there is nothing difficult about installing a toilet with your own hands, especially since you can do it yourself for free and save money. family budget. It is enough to carefully think through the plan of action for preparing installation, choose the right reliable tool and equip yourself with the necessary knowledge base for installing the installation and connecting the toilet.

Preparatory work

Installing a toilet correctly starts with careful preparation surfaces. If the bathroom is made new renovation and the floor is covered with tiles, consider yourself lucky and you can install the toilet with your own hands directly on it. If replacing the toilet is not related to repairs, then you should first dismantle old toilet and properly prepare the floor for the next installation.

Dismantling step by step looks something like this:

  1. Overlapping cold water so that the toilet tank does not fill up when flushing.
  2. Drain all remaining water from the tank by pressing drain
  3. Unscrew the hose connecting the tank and the cold water pipeline.
  4. We unscrew the fastenings of the toilet tank correctly to remove it. If the toilet is an older model, you may need an adjustable wrench or solid oil to make it easier to unscrew the old rusty fasteners.
  5. After dismantling the tank yourself, we move on to the toilet mountings. In Soviet times, toilets were often screwed to a wooden board, which was then concreted. Also, the toilet was installed on a sand-cement slide. In any case, you may need a chisel, spanners and a hammer. Carefully remove all traces of cement, screws and dowels.
  6. By slightly turning and shaking the drain, we grind off all the water remaining in it and carefully remove the plumbing product.
  7. Carefully close the sewer hole remaining after dismantling to prevent toxic fumes from escaping to the surface. This can be done using a wooden or rubber plug wrapped in fabric.

After the old toilet has been properly removed, you need to decide how to level the surface underneath it. If it stood on a wooden board in a recess, the board can be removed, the recess can be concreted and reinforced with a sheet of metal, and then the toilet can be mounted with your own hands.

If the earthenware piece of furniture was placed on a mound of sand-cement mixture, it needs to be disassembled with a chisel and hammer until the surface becomes even. A router with a wire brush can be useful.

Types of toilets

Toilets differ not only in shape and color, but also in the installation method, bowl shape and other parameters. Let's take a closer look at some design features toilets.

There are models with a funnel-shaped bowl, a bowl with a shelf or a visor type and with a sloped back wall. Installation of toilets different configurations may differ slightly in terms of design, but step-by-step instruction DIY toilet installation is the same.

Based on the installation method, toilets can be divided into floor-mounted and wall-hung toilets. There is also a hybrid version, which is also called floor-mounted. The peculiarity of such a toilet is that its bowl stands on the floor, like a floor-standing one, but the tank and all sewer lines are located in a false wall.

The advantages of a wall-hung toilet are the hidden tank, compactness and easy access to the floor underneath. On the other hand, a hidden tank requires the installation of false panels and, on the contrary, reduces the area of ​​the bathroom.

One of the most convenient types is a toilet with an oblique outlet. The wide mouth prevents clogging, and the stability of the design does not require the bowl to be attached. Installing a toilet with an oblique outlet is possible with your own hands; you can, of course, pay for the services of a specialist and wait for the final result, but many people decide to take the situation into their own hands and do everything for free.

Required tools and materials

Before installing the toilet, you should stock up on the necessary tools so that they are at hand at the right time. The list of tools includes:

  • A powerful electric drill or hammer drill with a set of drills for concrete or tiles.
  • Hammer.
  • A set of open-end wrenches or an adjustable wrench.
  • Roulette.
  • Pencil or felt-tip pen.
  • Screwdriver.
  • Pliers.
  • FUM tape.

In addition, you will need certain consumables and components:

  • Corrugation.
  • Flexible hose.
  • Sealing silicone with gun.
  • Toilet lining.

Step-by-step instructions for installing a new toilet

When all preparatory work for the installation of the toilet have been carried out correctly and the materials have been prepared, draw up detailed plan step by step how to install a toilet with your own hands.

Installing a traditional toilet floor structure can be independently produced in the following ways:

  • On a wooden stand
  • On epoxy glue
  • On dowels

Fastening to a wooden base step by step. If replacing a toilet is included in overall plan renovation of the room, it is best to install it on a wooden pad using fasteners, and subsequently concrete it correctly. When pouring the screed, the wooden base treated with drying oil is placed in the place where the toilet is supposed to be installed. In this case, you should take into account the dimensions of the plumbing fixtures. The board is filled with solution to the top and subjected to prolonged drying.

Toilet installation step by step epoxy glue. Fixing the toilet with epoxy glue will become excellent option if the bathroom has a perfectly flat floor:

  • The surface should first be degreased with solvent or any other substances.
  • The base of the toilet also needs to be treated.
  • Notches or marks are made with a pencil on the floor.
  • Next, the glue must be carefully applied to the plumbing product or floor at several points, usually four of them. After this, the toilet is pressed against the surface for 12 hours.

Installation of the toilet installation step by step using screws. If the base of the structure has holes for fastenings, it is advisable to install the toilet with screws or dowels:

  • We place the toilet as close to the wall as possible or in the way it will stand in the room.
  • You can connect the corrugation to the sewer system with your own hands in advance so that you can see at what distance from the wall the plumbing item should be placed.
  • Through the holes at the foot of the bowl, we correctly mark with a pencil or felt-tip pen the place for drilling holes for the dowels.
  • We set the toilet aside and drill holes.
  • We install the fasteners.
  • We install the toilet with our own hands so that the fasteners go through the holes in the toilet.
  • We thread a rubber or plastic washer-gasket so that the pressure of the bolts does not destroy the plumbing.
  • We tighten the bolts.

It is worth mentioning that some types of toilets are quite stable. Installing a toilet with an oblique outlet step by step does not require drilling or doweling.

A completely different principle for mounting and installing a wall-hung toilet. All sewer lines are hidden in the wall. To securely fasten a wall-hung toilet, a metal frame embedded in the wall is used. The wall-hung toilet is installed on it step by step, and the hidden tank and sewer and water hoses are carefully placed inside the structure, which is then covered with plasterboard or clapboard yourself.

The wall-hung toilet has a stylish appearance and a higher cost. If you look into it, connecting the toilet to the sewer wall type not much more difficult than usual floor mounting. You can easily learn how to install wall hung toilet on one's own.

Do-it-yourself toilet installation: video

To learn in detail and clearly see how to install a toilet with your own hands, we bring to your attention a video. After watching the video tutorial, you will be able to compare the characteristics of your toilet and independently connect the toilet with your own hands step by step.

Do-it-yourself toilet installation on tiles

Correct installation of a toilet on tile is considered the most difficult for several reasons. First of all, no one wants to ruin their new tiles. Secondly, this material can be quite fragile, so it requires particularly careful drilling. Thirdly, the earthenware toilet must be securely fastened to the tile, since its surface is smooth and the structure can move.

The presented video shows the correct installation of a toilet with your own hands, it is done on tiles step by step, so after carefully watching the video tutorial, we will easily learn how to install a toilet correctly.

  • The video begins with a story on how to install corrugation on a toilet. We can start the same way or change the order a little.
  • The video indicates that you need to measure the dimensions of the room in order to install the toilet exactly in the middle. This concerns separate bathroom. If you have a combined bathroom, before installing the toilet on the tiles, we need to first place it the way it will stand in the room.
  • We install the toilet on the tile, place it against the wall, trace the base with a pencil, as can be seen from the video tutorial on how to install the toilet on the tile. We mark the fastening holes in the same way.
  • We turn it over and inspect the toilet.
  • In places where holes will be drilled, you need to make notches so that the drill does not play on the tile and damage it.
  • We attach a drill of the required diameter to the hammer drill and begin drilling first in the non-impact mode. Only after the tiles have been completely drilled can the impact mode be used on the concrete floor.
  • Insert the dowels and drive in the screws.
  • We install the toilet with our own hands, thread the plastic gaskets and tighten the bolts.

Connecting the toilet to the sewer yourself

Once done reliable fastening, you can proceed to connecting the toilet to the sewer system step by step:

  1. First you need to install a corrugated or plastic adapter pipe with a slope of 45 degrees. The edges of the corrugation can be pre-coated with silicone grease for trouble-free installation. If the corrugation is located slightly to the side relative to the socket sewer pipe, it is necessary to connect the toilet to the sewer with an eccentric. Any gaps or irregularities between the corrugation and the riser can be corrected using FUM tape with your own hands.
  2. Connection cistern. We place the flush tank on the toilet bowl, having previously placed sealing gaskets in the places where the water hoses are connected.
  3. Connecting flexible hose one end to the entrance to the cistern, and the other to the water outlet, as shown in the video.
  4. Check the connection of the toilet to the sewer riser for leaks.
  5. Can the base of the toilet be sealed? silicone sealant.

When connecting the toilet, special attention should be paid metal parts, such as fasteners, screws and bolts. Over time, moisture can cause them to become covered with a layer of rust, which is neither aesthetically pleasing nor practical. It will be difficult for you to unwind them if necessary. Therefore, pre-treat them with grease or other lubricant.

One of controversial issues installation and connection of the toilet to the sewer system is considered wooden house. In fact, innovative waterproofing methods make it easy to furnish rooms high humidity in a wooden house. You can treat the walls of the bathroom and other rooms wooden house special water-repellent agents and are not afraid of wood swelling.

Another feature of a wooden house is that it shrinks several years after construction. To prevent this, the floor under the toilet in the bathroom of a wooden house should be additionally reinforced with reliable structures.

Installation cost

If replacement or correct installation toilet, the first thing we are interested in is how much it costs to install a toilet. Cost of installing a toilet experienced craftsman in the capital is at least 1,500 rubles. This does not include the cost Supplies– screws, corrugations, lubricants and the cost of dismantling if necessary.

You will have to buy them in any case, but if we have all the necessary tools for installing and connecting the toilet to the sewer, then the cost of all work is reduced by exactly the cost of ordering a qualified technician. You can perform many toilet installation operations for free, if, of course, you do this yourself.

Video tutorial on installing a toilet

To consolidate everything you’ve read and clearly see how to install a toilet with your own hands, you can watch the video tutorial.

Installation and connection of toilets of almost all modifications is carried out according to the same scheme. Usually the product comes with instructions, after studying which you can carry out the installation yourself. For your convenience, we suggest watching a video tutorial on how to install a toilet correctly.

Choosing a new toilet

Before going to the store for a new toilet, you need to decide on the size of the device and the method of connection to. This will depend on the outlet of the device. It can be of three types.

  1. Vertical.
  2. Horizontal.
  3. Oblique.

Vertical sewer pipe

After this, you can select a device from those models whose outlet drain design is suitable for connection to your sewer system. No adapter will help connect a toilet with a vertical flush to a horizontal sewer pipe. So this choice parameter is the most important, everything else is a matter of taste and wishes.

The shape of the toilet bowl can be:

  • disc-shaped;
  • funnel-shaped;
  • visor.

Types of toilets according to bowl shape

The visor design prevents the formation of water splashes when flushing. Water flushing can occur in a circular manner or in a continuous stream.

The toilets themselves can be different designs. It can be a monoblock, a corner toilet, a compact toilet or a separate one, when the bowl and toilet are located separately.

Toilets by mounting method

According to the method of fastening, toilets are divided into attached and free-standing. The attached one looks like a wall-hung toilet. Available for sale with or without a tank. Attached different ways. Most often this is an option with two or four mounting lugs for an anchor or screw, but there are models that are attached to special corners fixed in the floor.

Connecting elements

To connect the toilet to the sewer pipe, you will need connecting elements. You just need to choose the right one.


All elements are connected hermetically due to rubber seals. The exception is when connecting the cuff to an old cast-iron sewer pipe. In this case, the joints are coated with sanitary sealant.

Dismantling the old device

Before starting work, prepare a bucket and rags. First of all, turn off the water supply valve to the drain tank. Drain the water and unscrew it from the tank water pipe. Now we disconnect the tank from the bowl; most likely the mounting bolts are rusty and oxidized or stuck with deposits. Use a hex socket wrench; if you can’t unscrew it, try tightening the bolt slightly. Forward movements The nut should turn back and forth. Don't try too hard to avoid breaking the tank. If this does not help, then spray the nut with WD-40, kerosene or turpentine. After a day, try to unscrew it again using the rocking method.

Disabling the cistern of an old toilet

Now you can move on to unscrewing the toilet. Fasteners can be anchor bolt with a nut or dowel. If the toilet was installed many years ago, then most likely it was installed with cement mortar. In this case, it is unlikely that it will be possible to keep it intact, especially if the drain is secured oil paint with rags or cement coating. The easiest place to start is with the drain neck. Short with a strong blow hit the neck, it will crack and separate from the sewer pipe. Do not hit the drain pipe; cast iron is a very brittle metal and can crack or split, adding additional problems.

Toilet dismantling work

Using a chisel and hammer, hammer away the cement mortar at the base of the toilet. Try rocking the device, then tilt the toilet back and drain the water from it into the sewer. Make sure that no debris gets inside the drain pipe. Now, using a screwdriver, carefully clean the neck of the sewer pipe from the solution of other dirt and insert the adapter eccentric collar, previously well lubricated with sanitary sealant. We plug the hole with a rag so that the dangerous and unpleasant aroma of sewer gases does not spoil your mood and health.

Installation: anchors or dowels

Installation on dowels involves installing the product on the bathroom floor without placing any lining such as taffeta under its base. Modern toilets are produced with mounting holes in the base, so this installation method is the most practical and most frequently used. After leveling the floor or laying tiles, you must perform the following steps:

  • Using plumbing lubricant, we put an eccentric cuff on the toilet outlet, push the toilet to the intended place, and insert the cuff into the adapter. By turning the cuff, we align the toilet evenly. With a marker or pencil inserted into the mounting hole, mark the mounting points and the contour of the bowl;

Stages of installing a toilet on dowels

  • disconnect the toilet from the adapter and move it away. Use a drill to drill holes for the dowel. Please note that if the holes in the toilet mounting lugs are oblique, then we drill a hole for the dowel, also at an angle. We hammer in the dowels;
  • We install the toilet according to the marks and connect it to the sewer. We put a plastic sleeve (or rubber washer) on the screws and tighten it a little on the dowels;
  • We level the bowl; if the base is not level, then place pieces of rubber or sheet plastic, and then tighten the screws completely. Do not force yourself too hard to avoid breaking the ceramic. We put a plastic plug on top of the bolt. Seal the gap with silicone sealant, remove excess silicone with wet fingers.

Advice. It is better to try on a toilet with a flush cistern installed on it, and install it without a cistern.

Installation on taffeta

Installing a toilet on taffeta was previously considered a generally accepted installation method. We will not recommend it, since a toilet installed in this way will become loose over time. The reason for this is moisture that gets on wooden surface. The board is laid in the floor level with the surface and secured with anchors. The remaining space is filled cement mortar and after the mixture has completely hardened, installation begins. The installation process is the same as installation with dowels, only the mounting ears of the toilet bowl are screwed to the board with self-tapping screws, having previously placed rubber washers under the heads.

Installing a toilet on taffeta

Installation on epoxy resin

If there are no mounting lugs at the base of the toilet model, then such a device is attached to an adhesive connection. This option is suitable for devices in which the flush cistern is mounted on the wall without resting on the toilet bowl or where a drain tap is used instead of the cistern. After fitting and applying a contour mark, the surfaces to be glued are lightly processed sandpaper or a corundum stone to give them roughness, and then degrease them with a solvent. Then epoxy adhesive is applied to the dry floor surface with a layer of 4 - 5 mm and the toilet is pressed with force. After the glue has completely cured, you can use the device.

Installation on epoxy resin

Advice. When working with epoxy glue, use gloves to protect your hands.

Suspended installation system

To install a wall-hung toilet, you will need a special frame with a flush cistern, which is equipped with a flush mechanism and lined with insulating material to absorb noise and prevent the formation of condensation. Typically, this design is purchased separately from the toilet. The frame is attached to the wall with anchors, and the toilet is hung on it. Communications are hidden inside the frame, which is subsequently sheathed moisture-resistant plasterboard and lined. The drain button is mounted in the wall on the front panel of the tank.

Suspended installation system

Connecting the tank to the toilet bowl and water supply

After the toilet is installed, you need to install the flush tank on it. Internal filling assemble according to the instructions. Place a gasket on the bowl (it may have different shape) and secure the tank to the bowl so that it does not move relative to its place. You can glue it to the bowl with silicone. The screws are tightened evenly. We connect the flexible hose from the tank to the water supply. On threaded connections We wind FUM tape for compaction. It would be a good idea to install a shut-off valve on the water pipe.

Connecting the toilet cistern

If it is necessary to repair the product, the tap will allow you to locally shut off the water supply. All that remains is to test the tightness and quality of the system. Shifting the float higher or lower allows you to adjust the level of water filling in the drain tank. Fill the tank with water several times and drain. The absence of leaks and trouble-free operation of the device indicates that the installation was successful. The finishing touch will be the installation of a toilet seat, which after all the work done will be a mere trifle for you.

Installation work new plumbing Many novice craftsmen have concerns. Diversity constructive solutions plumbing fixtures and methods of connecting them requires the performer to know the intricacies of the process.

We will try to reveal the main ones and analyze how to correctly install a toilet with your own hands without the help of plumbers.

The range of plumbing fixtures on the market is varied. Any owner has the opportunity to choose a presentable and functional equipment according to your own taste and wallet.

In addition to traditional floor-standing models, manufacturers offer a wide selection of wall-hung and built-in devices. The drain tank in them can be attached to the wall or connected to the base of the plumbing fixtures.

Option for the bowl of floor and hanging models can be anything, for example, dish-shaped, funnel-shaped or even visor modification

The latest toilet models also differ in the design of key components.

The output discharge is:

  • horizontal;
  • vertical;
  • oblique.

The type of outlet drain should be taken into account when choosing a model. If your plans do not include reworking the sewer pipe supply, then in the installed model the drain should be arranged according to the same principle as in the dismantled one.

Inconsistent drains and plumbing supply, provided that it is not a toilet with an outlet, are almost impossible to combine as tightly and efficiently as possible.

Fixation of plumbing fixtures to the floor is carried out using specially made two or four fastening points. But you can also find models in which the corners included with the product are used for fastening to the floor.

A new plumbing fixture can be placed in the place of the old one, or you can choose another “corner” for it by making small redevelopment in the bathroom.

Preparation of tools and materials

To connect the tank to the water supply you will need a flexible hose. It usually comes included. For connection to the sewer - a rigid or bendable corrugated cuff.

It is impossible to perform high-quality installation of a toilet bowl with your own hands without minimum set necessary tools that any owner has in their home

To assemble the structure and connect to communications you will need:

  • hammer drill or impact drill;
  • a set of screwdrivers with flat and Phillips blades;
  • set of wrenches;
  • building level;
  • a simple pencil or marker;
  • stationery knife;
  • roulette;
  • chisel;
  • hammer.

If the installation of plumbing fixtures will be carried out on tiles, then it is also necessary to prepare a “ballerina” or a spear-shaped drill for working on tiles. To make holes for installing fasteners, you will also need an 8 or 10 mm drill.

From auxiliary materials You will also need:

  • metallized tape;
  • silicone sealant;
  • FUM tape;
  • polyethylene film;
  • moisture-absorbing piece of fabric;
  • container for collecting liquid.

Depending on the type of model being connected and the installation method, cement mortar may also be required.

Removing an old toilet

Removing an old toilet is one of the most time-consuming operations.

The work is carried out in several stages:

  1. Turn off the tap.
  2. Disconnect the hose going to the tank from the water supply and drain the water from it.
  3. The empty tank is removed from its mounts.
  4. Unscrew the nuts located on the back of the toilet and disconnect it from the sewer. To loosen the drain, the toilet needs to be rocked from side to side.
  5. Drain the remaining water from the toilet by tilting the bowl forward.
  6. The sewer hole closer to heaven is cleared of dirt and temporarily blocked with a rag gag or a wooden plug of suitable diameter.

The easiest way to remove the bolts is to hold the head with an open-end wrench and unscrew the nut with an adjustable wrench. If the threaded connections are heavily slagged with salt deposits or rusted.

To make the task easier, use universal lubricant “WD-40”, which can loosen deposits in a matter of minutes. In the absence of one, you can use vinegar or kerosene.

The sewer hole must be closed so that toxic hot gases do not spread beyond the pipeline

If rotten taffeta or any other support is found under the dismantled toilet, it must be removed. This can be done with a hammer drill, nail puller or chisel.

In older houses, drains on sewer pipes are often secured with cement coating. The easiest way to knock down dried mortar is with a chisel, pricking it in several places. Detailed instructions Read about dismantling an old toilet.

Option #2 – with horizontal outlet

Plumbing fixtures with horizontal outlet have become one of the most popular in our country. The relevance of installing such equipment is explained by the specifics of wiring in Russian apartments sewerage systems.

The main feature of toilets with a straight horizontal outlet pipe is that for proper installation a strictly fixed connection point to the communications is required

The horizontal outlet is located at the back of the bowl or base and is directed backwards. Models with this design are installed end-to-end with the wall, connecting to any type of arrangement sewer riser.

The connection is made using pipes of the appropriate size. The connection is sealed by placing it inside the pipe sealing gum.

Direct connection is made only if the sewer system is made of plastic. To connect to cast iron pipes, whose circumference rarely has perfect shape, cuffs and eccentrics are used.

Option #3 – with oblique release

The socket in models with an oblique outlet is located at an angle of 45° relative to the floor surface. Models with an inclined outlet are superior to their counterparts in that they are less likely to become clogged, since this design makes it possible to create less resistance when moving solid sewage.

The weak point of devices with oblique outlets is the connection points between the product and the sewer pipe, which can become covered with cracks if installed incorrectly

Connecting a device with an oblique outlet to the sewerage system can be done in one of three ways:

  1. By direct connection through the sewer branch socket. They are chosen when there is no need to move the plumbing fixture, and the direction of all elements clearly coincides. The toilet outlet is being processed soap solution and buried in a socket equipped with a cuff.
  2. Connection via eccentric. A socket with a center offset of 5 cm, equipped with a sealing gasket, is mounted in the sewer outlet and by rotating the toilet is shifted to the right or left side.
  3. By installing a corrugated outlet. The use of corrugation makes it possible to deploy the relative oblique sewer outlet device even at an angle of 90°.

A flexible outlet, although convenient, is far from the best means for connecting toilets with an oblique outlet. It should be used only in extreme cases, when other methods are not possible.

To find out in more detail how to install a toilet with an oblique outlet, go to.

The most simple option connecting a toilet with an oblique outlet is the use of corrugation, which ensures perfect tightness

If a long-term connection is not made with the help of corrugation, then you need to use a reinforced version of the corrugated pipe

Using a corrugation, a toilet with an inclined outlet can be connected to a drain located in the floor or wall

If it is possible to reduce the distance between the toilet and the sewer system, instead of corrugation, it is recommended to use a sealed cuff and a plastic outlet

Features of installation of compact models

The technology for correct installation of floor-standing toilets of compact models includes seven main stages:

  1. The toilet bowl is moved as tightly as possible to the drain hole and checked whether the outlet coincides with the sewer pipe.
  2. If there are small displacements, the device is connected to the sewerage outlet using a corrugated pipe.
  3. The plumbing fixture with the connected corrugated pipe is moved towards the wall, making sure that strong creases and bends do not form on the pipe.
  4. The ends of the connecting element are covered with a thin layer of silicone sealant.
  5. Having adjusted the position of the device, use a pencil to mark the outline of the boundaries of the base of the device and the points where it is planned to drill holes for deepening the dowels.
  6. The toilet is moved to the side. At the designated points, holes are made with a diamond drill with a diameter equal to the size of the dowels used.
  7. Plastic plugs are inserted into the holes. The toilet is “reinstalled” in its original place. Bolts are screwed into the prepared holes.

Tip: to make it easier to put the corrugated pipe on the outlet, its end must be coated with liquid soap on the inner walls.

If holes have to be made in tiles to minimize damage to the surface, first slowly drill the top layer by hand, and only then turn on the hammer drill with impact drill mode

To ensure the tightest possible fit of the toilet sole to the floor covering, silicone is applied along the intended installation counter of the device. The toilet itself is then placed in its original place, guided by the intended contour.

To fix the plumbing fixture, washers and screws threaded through the holes in the heel are tightened extremely carefully. Under no circumstances should they be driven in!

Before installing a new toilet, we dismantle the old plumbing, clean the floor under it, repair it and fill it with semi-dry cement mortar

We install a new plastic adapter into the sewer outlet, to which we will connect either a corrugation or a rigid plastic elbow

If necessary, we change the cold water supply pipes in the area behind the toilet. Most often this has to be done so as not to change the pipeline a year or two after installing new plumbing

According to the completed connection from the toilet to the sewer, we set up the plumbing fixtures for fitting in order to mark the attachment points and outline the leg

Introduction

“How to install a toilet with your own hands?” - this is the question every owner asks new apartment or at home. - an integral part of any apartment or house. It, like a bathroom, a sink, requires connection to a water supply system, to a sewerage system, city or private, and requires complete isolation of internal water. For its full operation, it is necessary to adjust the flush handles, permanently set the tank, check the entire structure for cracks, and much more. At first glance it seems like hard labor, but it will still be better if you do it yourself. So, if it breaks, you will quickly find your bearings and fix the leak. If the work is done by experts, you will have problems.

Installation of the drain mechanism

Before buying a toilet

Before purchasing, you need to check the dimensions of the product and compare them with the dimensions of the toilet. It is worth considering all the nuances flooring, make sure the quality and reliability of the device. If you have any preconceptions about toilets, put it out of your head, it's just a regular piece of stone. For now.

Stage 1. Installation of the drain mechanism

The toilet in its original form is a bowl, inside which there is a shut-off pipe and other parts. To complete a complete DIY toilet installation, you need to assemble them together so that everything is airtight. This is done by tightening many nuts, screws, and fasteners.

First you need to insert the drain mechanism - it is delivered already assembled - into the only big hole at the bottom of the tank, then secure it with a nut or two, depending on the design of the tank. The nut is tightened either by hand and your own tools, or with the special wrench included in the kit. Be careful not to damage the pipe, otherwise it will cause problems later. constant problems. For proper insulation At any connection, rubber gaskets are installed. In this case, place it in the inside of the tank, but do not twist anything, or it will tear.

Connection of bowl and tank

Stage 2. Connecting the bowl and toilet cistern

To connect the tank to the toilet bowl, you will first need to wear rubber compressor to the drain mechanism. This is done for safety and tighter isolation. Now carefully place the tank on the bowl, focusing on the shaped features and holes for the nuts. Make sure that both parts are perfectly aligned so that there are no even small holes or other errors. Installing a DIY toilet will be quick and easy if you check every step carefully.

Now let's fix the tank to the bottom of the toilet; to do this, count the number of holes for the nuts and take metal washers, studs, cone gaskets and nuts in exactly the same quantity. This will avoid missing holes and secure the device as much as possible. For each of them, you must first connect the pin with the washer, then put a conical rubber gasket on top and install this structure on the hole. Carefully insert the nut and screw it in. Remember, you cannot tighten the nuts completely at once; first, fill all the holes and twist evenly, that is, first turn each screw halfway, then tighter and all the way. It is optimal to screw everything in three approaches; you should not try to save time and rush.

Autonomous toilet

Types of tanks

How to install a toilet with your own hands if you have a non-standard type of cistern? Let's figure it out. There are three types of tanks:

  • Standard, attached to the bowl;
  • Autonomous, located above the bowl, suspended from the wall;
  • Built-in, found in wall-hung toilets;

The difference is the location of the tank, the method of draining, and the fastening. In essence, the technologies are quite similar, but the installation is still slightly different.

Installation of an autonomous tank

The autonomous tank is attached to the wall using bolts, nuts or another method suggested by the manufacturer. The tank is attached to the toilet using a drain pipe. This type of toilet is not very convenient; it is used in in public places, but if you use it, then the installation procedure is as follows: first, attach the drain pipe to the toilet without attaching it to the tank. We mark the lower attachment point. Tighten the nut or bolts at the connection between the pipe and the bowl. After this, calculate the height of the tank mounting and mark it with a marker. Use a level to set the ideal position of the pipe and secure it to the wall, having first checked the height. We connect the tank and pipe using the same method as with the bowl, then screw both elements to the wall using brackets and dowels. Installation is complete. After the toilet is completely installed, check the functionality of your system and inspect it for leaks.

Built-in toilet

Installation of a cistern built into the wall

The next type of toilet is, which, unlike the previous one, has a completely different fastening technology. Here the main element is the tank, not the bowl, it closes wall panels, tiles, drywall - any accessible method. The advantages of this model are that it takes up little space and looks non-standard; there are design ideas that turn the toilet into something completely unpredictable. If you want to diversify the style of your apartment, this option is right for you. The disadvantages of this type are unreliability (depending on quality) and high cost. Usually the installation technology is described in the instructions, as there are different variants installations. However, it does not say how to install a built-in toilet with your own hands so that it works specifically with your sewerage and water supply system. Typically, the tank is suspended from the frame, secured with several bolts and nuts through a gasket, carefully checked for strength and reliability, where the unique installation ends. Adjust the drain to save water and proceed to the lower paragraphs, which will describe in detail how to attach the unit to a sewer or water pipe.

How to install a wall-hung toilet with your own hands

Connection to sewerage

Step 3. Attaching the float to the assembled part

It was possible to connect the toilet with the float before, but then it would interfere with tightening the nuts. Correct assembly This is done like this: put a rubber seal on the thread of your float, also for safety, now insert it into the tank with the side where the thread is located on the float. You need to connect the tank and the float from the inside, then, as in previous cases, lightly secure it with a suitable nut.

We have already solved half the question of how to install a toilet with our own hands - the device is fully assembled and ready for use. Now you need to properly connect it to your sewer and water supply system and install it in a specific place.

Stage 4. Connection to the sewer

Before connecting the toilet to sewer system, you need to accurately choose a place for it, punch a hole for the pipe. If you have done this, proceed with the connection. For this it is better to use, it combines strength, durability and, importantly, flexibility. With this material you can move the toilet within its length, which will be very useful for further work. The installation of a corrugated outlet is carried out as follows: the side with the feather gasket is inserted into the sewer pipe, and the other - onto the outlet part of the toilet. Tighten these holes as much as possible, they will fasten themselves.

Installation process

Stage 5. Installing the toilet on the surface

The next stage is installation, attaching the toilet to its proper place with your own hands. First, determine the position in which it will be comfortable for you to sit, the toilet will not wobble or creak, the corrugated pipe will hang freely and will not stretch or compress. Now let's turn our attention to bottom part toilet - here you can see several holes. Draw their outline with a marker or other writing medium and move the toilet away, but be careful not to damage the incoming pipe.

It is optimal to first move it a little to one side to drill holes from one part, then do the same on the other. The most convenient and correct way to do this is with a hammer drill; under no circumstances drill holes through the toilet itself; cracks, chips, and breaks are possible. Better spend your time doing quality work.

Stage 6. Tighten the nuts

Insert into the holes made plastic stoppers supplied with the toilet. Now move the toilet back to the desired position and screw it using the long screws that are usually included in the kit. As in other cases, do not forget to install metal washers, cone gaskets and studs. Try to shake the device in place, if it moves, twist it harder, otherwise when you sit on it, it will shake and eventually break. Ultimately, the toilet will stand firmly on the surface, no movement will generate a squeak. At this point, do-it-yourself toilet installation is complete, all that remains is to attach iron pipe connecting the unit to the water supply system. This process is a little more complicated than the previous ones, but quite doable.

Metal-plastic pipes

Stage 7. Connecting the plumbing system - options

When connecting the water supply to the toilet, you can use two types of pipes - a flexible hose, the negative aspects of which are unreliability, creaking, leaks, and fragility. It will constantly get in the way, bend and wrinkle. Positive points- ease of connection, possibility of installation on toilets of non-standard format.

The second method is a metal-plastic pipe, reliable, strong, but not bendable at all. Poor quality models, which are on modern market Most of all, they will leak and rust. On the other hand, if you buy an expensive and high-quality pipe, it will last a really long time and will not cause any problems in the future, which cannot be said about even the best hoses. We recommend using this method.

Stage 8. Connecting the water supply system. First way

Correctly installing a toilet with your own hands involves spending your personal time, but if you still decide to finish this job quickly, use a flexible hose. It is best to buy a corrugated hose, its advantages have been described. For correct fastening, attach one end of the hose through the gasket to the toilet, the other to the water supply system. After this, tighten the ends, but do not use excessive force - the gasket may break and then the hose will start leaking from the very first use. If during operation you damage the hose, you will have to replace it, since its repair will cost you a lot of time, although a positive result is not guaranteed.

Stage 8. Connecting the water supply system. Second way

Let's look at the second method in detail - connection metal-plastic pipe. It is installed in the same way as a flexible hose, only you need to twist the ends even more carefully - the metal will easily cut the gasket, so you need to find a middle ground between under-twisting and over-twisting. Metal pipe will not bend or interfere, so for this case it is ideal option. After its installation, work with the toilet will be finally completed. All that remains is to attach the lid to the toilet, seal the joint between the unit and the floor, and that’s it. Don't forget to add a tap to your pipe that can quickly shut off the water supply - this will prevent serious water leaks.

Bottom line

After reading of this material your question about how to install a toilet with your own hands will be settled. The main rules when installing a toilet are accuracy, patience, and attentiveness. Follow these rules and you will succeed. Remember that for the first time after final installation Various problems may arise, such as leaks. Don't worry, sometimes after twisting the pipes may come off and leak. If you encounter this problem, just tighten the required nut.

If you have started a major renovation of your bathroom, or the plumbing has broken down, then you may need to replace the toilet. This process has a number of features that must be taken into account, and the approach to choosing a new toilet must also be correct.

Of course, you can call a plumber from the housing office, or contact private craftsmen who will provide professional installation. But installing a toilet yourself will not only save you money, but will also allow you to understand the whole process, which means choosing the most suitable installation option.

In this article, we'll walk you through everything you need to renovate your toilet to help you do the job yourself.

The first thing you need to decide is which toilet to choose.

Replacing a complete toilet is part of a comprehensive package, so it includes:

  • selection of a new toilet, taking into account the mounting and drainage methods;
  • dismantling the old toilet;
  • renovation of the toilet room, including replacement of pipes, screeds, cladding and other things;
  • installation and connection of a new toilet.

Buy new toilet should be done in advance, and at the same time you need to consider some features that will help you make the right choice.

Floor-standing toilets are divided into several types according to their design. Their differences are based on the shape of the main nodes.

  1. The shape of the outlet drain can be horizontal, vertical or oblique, at an angle of 45 degrees.
  2. The toilet bowl can be visor-shaped, plate-shaped or funnel-shaped.
  3. The models also differ in the type of cistern: it can be combined with the base of the toilet or installed on the wall, and at different heights.
  4. The fixings of the toilet to the floor vary. This may be an option with two or four fastening points, or a design in which the toilet is installed on special corners attached to the floor.

Tip: choose a toilet based on the type of drain. If you are not going to change the sewer pipe, then take a model with the same type of drain as the old toilet. No adapters will provide a high-quality connection to a toilet with a vertical and direct outlet.

The method of connecting the tank will determine the types of further facing works V toilet room. For example, if you choose to mount it to a wall, you will need a prepared place and anchors for installation.

  1. First of all, the water supply inside the drain tank is shut off, the water is drained from it and the underwater hose is unscrewed. After this, the fastenings of the tank are unscrewed. If they are rusty or covered with lime deposits, you need to hold the bolt head with a screwdriver and unscrew the nut with an adjustable wrench. Use kerosene or aerosol lubricant - these products significantly soften rust and lime deposits.
  2. After the tank is removed, unscrew the fastenings that hold the toilet - dowels or nuts screwed onto the anchors.
  3. Now you need to disconnect the drain from the sewer pipe. If your house is still an old building, then most likely the drain will be fixed. In this case, you will need a hammer and chisel. Position the chisel across the caulk and carefully prick the cement in two places. Rock the toilet with force so that the drain rotates and becomes loose. Tilt the toilet without disconnecting it to drain the remaining water.
  4. After dismantling the toilet is completed, close the hole in the sewer pipe with a wooden plug or fabric stopper.

Dismantling the toilet does not require special care, because you are unlikely to reuse the product. Therefore, if the cement coating is too strong, you can beat off part of the toilet bowl with a sledgehammer to make the work easier, and then make a transverse hole in the pipe and insert a metal rod there as a lever to make it easier to loosen the drain.

Please note: if you have cast iron drain pipes in your apartment, it is better to immediately replace them with plastic ones. The operation of PVC pipes is much simpler, both for the initial wiring and when connecting all drain points.

DIY toilet installation process

After you have dismantled the old toilet or completed all the finishing work, prepare the surface, level it and begin installing the toilet installation.

  1. Attach a rigid pipe to the toilet flush or corrugated pipe, for connection with the sewerage outlet pipe. The optimal option would be one in which the toilet flush goes directly into the pipe outlet. Use a rubber seal with a border. Do not seal the transition of the drain into the sewer inlet with cement.
  2. Prepare water input. A flexible hose that is screwed onto the inlet of the tank and the water supply tap is well suited for this. Pay special attention to the diameter of the hose fasteners at both ends.
  3. After the connection is made, you can fix the toilet to the wall or floor. Below we will look at this process in more detail.
  4. Assemble the toilet. Place the tank on the pre-fixed base. If your tank is suspended, secure it to the wall and run a pipe. Now you can check whether the tank settings are correct and the toilet is operational. Turn on cold water and wait for the tank to fill. While the water is filling, you can adjust its level. You can learn more about this from the instructions for the tank.
  5. The last stage is attaching the toilet seat. There are holes on the top of the toilet bowl for mounting it, and the necessary parts are supplied in the kit.

Now we will look in more detail at the methods of attaching the toilet, as well as the features of each of them.

How to install a toilet correctly, taking into account every little detail

There are usually three options for attaching the toilet to the floor:

  • installation using anchors embedded in the screed or dowels;
  • fixing the toilet with screws to a wooden base previously mounted in the screed;
  • installation on epoxy resin.

If you decide to change the toilet due to overhaul, then suitable option will be anchored or prepared wooden base. In this case, the anchors for attaching the toilet are placed on the floor when forming the screed. They should be installed so that they protrude 5-6 cm above the surface. The excess can then be cut off.

Choose taffeta ( wooden board) to the size of the toilet base. Drive nails in a checkerboard pattern over its entire surface so that they protrude from the other side. Now turn the taffeta over and install it where the toilet will be located. Fill the screed with concrete along the top edge of the board, install the toilet and secure it carefully with screws.

For attaching the toilet to tiled surface There are also certain rules. Be sure to wear rubber gaskets under the nuts and on the dowels: they will prevent the toilet from cracking when tightened and will prevent rusty streaks on the ceramics. Use nickel-plated anchors and bolts; they can be easily unscrewed even after their service life has expired.

Advice: when installing the toilet on, to prevent damage to it appearance, use epoxy resin or dowels.

Under the dowels you will need to make holes through the screed and tile into which the screws will be screwed. The holes should not be too deep so as not to touch the waterproofing layer. If the screed is too thin, pour some sealant into the hole before installing the dowel. Be sure to put a rubber gasket on the screw. It would be best to place the toilet on a sealant pad and then press it down with screws.

What other options are there for installing a toilet?

When installing a toilet, you can completely do without such parts as anchors, dowels and screws. will come to your aid epoxy resin. The main thing is to prepare the base of the toilet and the floor surface according to all the rules. This option is optimal if the tank is mounted on a wall, since it represents half the weight of the complete structure.

  1. First, run sandpaper or an abrasive stone over the surface of the floor so that the epoxy resin will set and adhere well.
  2. Apply adhesive to the floor and base of the toilet in an even layer of a few millimeters. Install the structure, level it and wait for the resin to dry completely.

Recently, wall-hung toilets have become popular. They are installed on the wall, without any contact with the floor. For installation you will need to make a metal frame and attach it to load-bearing wall, and directly fix the toilet on it if you plan to hide the pipes and tank behind a plasterboard wall.

You can also mount a wall-hung toilet with a cistern open type straight to the wall, but in this case you will need to move the sewer pipe into the thickness of the wall. The structure is secured by using anchors built into the frame or wall.
