Modern technologies for the manufacture of plumbing fixtures make it possible to fill the building materials market with various models of toilet bowls.
Sanitary appliances differ in modifications of drain tanks, material of manufacture (porcelain, faience), fastening device, location of water supply and drain outlet. In most cases, bathrooms and toilets are tiled.
The walls and floors are covered with tiles. How to fix a toilet bowl on a tiled floor so that it stands firmly on its base? In this article, we will give the reader information on how best to do this.
Preparatory work before installing the toilet
Achieve a comfortable toilet pipe length
The drain sink is installed when the wall and floor tiling work is completed.
If you install the plumbing first, and then proceed with the ceramic flooring, you will have to deal with a rather complex cut in the slabs to bypass the base of the pedestal of the plumbing fixture.
This will cause the risk of damage to the cladding if the selection of cut tiles is unsuccessful.
When facing walls and floors with ceramic tiles, you need to achieve a convenient protrusion length from the wall of the water pipe.
The outlet of the water pipe must be such that a stopcock can be installed.
The sewer drain can protrude from both the wall and the floor. The sewer socket must provide a tight connection with the corrugation.
Necessary tools and materials
To successfully complete the task, you should acquire patience and prepare the following set of tools:
- perforator, drill;
- marker;
- drills for glass and ceramics;
- screwdrivers;
- sealant;
- spanners;
- adjustable wrench and cap heads with a collar;
- dowels with self-tapping screws;
- pliers;
- corrugated pipe;
- tap;
- core;
- grinder with an abrasive wheel;
- connecting hose.

Installing a toilet on a tiled floor
Toilet installation
The installation of the toilet bowl on the tiled floor is done in different ways, depending on the position of the mounting holes in the sink pedestal.
There are three options for attaching a plumbing fixture to a ceramic floor:
Installation of a toilet bowl with a vertical mount
Most models of drain sinks are made with mounting holes for vertical fasteners. The installation of the sink is carried out in several stages:
Before installing the toilet, check the horizontal position of the installation site. If no deviations are found, then the base of the pedestal and tiles are not cleaned along the contour of the sink support.
Side fixation of the toilet
Installing a toilet with side mounting holes is somewhat different than installing a sink with vertical fasteners.
The difference is that the mounting parts are hidden under the instrument's pedestal.
Install this model of the device as follows:
Attaching the base of the toilet
This installation method is resorted to if the floor base is equipped with a heating system. There is a risk of damage to the heating equipment when drilling mounting holes. For more details about the work, see this video:
In this case, cleaning the base of the pedestal and the surface of the ceramic tile along the contour of the toilet bowl support is mandatory. This is done to increase the adhesion of the surfaces to be glued.
Press the toilet firmly against the floor
Glue the toilet on the tiled surface with liquid nails. The surfaces are covered with glue, then they are pressed against each other.
The toilet bowl is removed from the installation site and placed on its side. Withstand the time specified in the instructions. Then set the sink in place, press it to the floor.
The rest of the installation work is carried out in the same way as in the previous cases.
You can start installing a toilet on a tiled floor on your own only if you have the skills and experience in this type of work.
To properly install the toilet on the tile, follow our step-by-step instructions, provided with photos and videos.
Working time: ~ 1 hour.
Total time: ~ 24 hours.
Preparing a room for a toilet
It is better to install the toilet bowl in a completely renovated room so as not to damage the plumbing. You should have a hole ready for the outgoing sewer pipe, as well as a water outlet for the drain tank.
Tools and materials required for proper installation
To install the toilet, we need the following tools and materials:
- Adjustable wrench
- flexible hose
- fum tape
- Pencil or marker
- Yardstick
- A hammer
- Dowels and bolts (should come with the toilet)
- Sanitary lubricant
- liquid silicone
- rubber spatula
How to properly install a toilet bowl with your own hands
Step 1. Eyeliner to the drain tank
Shut off water access to the system. Unscrew the plug on the water outlet using an adjustable wrench. A crane must be connected here. An angled or straight faucet of your choice can be used. Seal the threads on the faucet with fum tape and screw the faucet into a water outlet. If using a corner tap, screw it in so that it points down. Shut off the faucet valve.
Screw the flexible hose to the faucet outlet. It is not necessary to use a fum-tape, since a sealing gum is provided in the design of the flexible hose.
Step 2. Marking the toilet installation guide
To install the toilet exactly in the middle of the toilet, measure the width of the room against the wall and mark the middle with a pencil. Do the same in the middle of the room and draw a line along the two marks. This line will be our guide, determining the direction of the correct installation of the toilet.
Step 3. Assembling the sewer drain
If necessary, supplement the sewer drain with an angled pipe (45-90 degrees) so that its opening looks towards the outlet pipe of the toilet at a smoother angle.
Advice: To make it easier to connect two pipes, use plumbing grease. Apply it to the inside of the drain hole (lubricate the rubber o-ring) and to the outside of the elbow pipe that will fit into the hole.
The sewer drain can be connected to the outlet of the toilet in two ways:
- hard plastic adapter;
- flexible corrugation.
In both cases, when inserting the connector, use plumbing grease as above.
Step 4. Preparing the base of the toilet and marking it on the tiled floor
Advice: Do not pre-connect the tank to the toilet. When and how to connect the tank to the toilet, you will learn later in the article.
Take the base of the toilet and turn it upside down. The edge of the supporting part of the toilet must be smooth, without defects. Clean it up if necessary with a sharp knife.
Place the toilet base on the floor at the installation location. Follow the line you drew earlier (see step 2) to position the toilet correctly and exactly in the center of the toilet. Additionally, check the correct installation by measuring the distance from the toilet to the left and right walls with a tape measure.
Connect the toilet pipe to the drain system adapter and outline the perimeter of the toilet base with a pencil or felt-tip pen - this will help you install it in the future without additional measurements. Also, on both sides, mark the locations of the holes for fasteners.
Step 5. Fixing the toilet to the tile floor
Set the toilet aside and drill holes in the tile for fasteners. Use a special tile drill. The depth of the holes should be equal to the length of the dowels that come with the toilet. Hammer plastic dowels into the holes drilled in the tile.
Put the toilet back in place along the drawn lines and connect it to the sewer drain. Screw the metal screws with washers that come with the toilet into both mounting holes, but only halfway.
Step 6. Additional fixing of the toilet bowl with liquid silicone
Raise the toilet bowl by 0.5-1 cm, place any supports in two or three places (use what you have at hand - plastic, pieces of tiles, etc.). Very carefully inject white liquid silicone into the gap between the base of the toilet bowl and the floor tiles. Do this around the entire perimeter of the base of the toilet. Raise the sides of the toilet bowl with your hands and, taking out the stands, add silicone. Silicone should be evenly distributed around the entire perimeter of the base of the toilet and create a plentiful "cushion".
Lower the toilet and tighten the fixing screws all the way by hand (without excessive force). Remove excess silicone that is outside with a plastic spatula moistened with soapy water. Form a beautiful edging around the entire perimeter of the base.
It is necessary to wait a few hours (see the curing time of the silicone on the packaging), and only then proceed with the installation of the toilet.
How to install a toilet flush mechanism
Put a gasket on the threads of the main drain and insert it into the process hole of the drain tank. On the reverse side, tighten the wide nut with your own hands - do not use tools to avoid splitting the tank.
Advice: We recommend installing a locking device that controls the flow of water into the flush tank after installing the flush tank on the toilet bowl. This will make tightening the mounting screws more convenient - you will not be disturbed by an extra mechanism inside the tank.
When installing the locking device, check for burrs on the bottom of the device where the hose is put on. Remove bumps so that the further connection is tight. Insert the locking device into the hole in the tank intended for it and tighten it from the back with a plastic nut. Again, do not use any tools, tighten the nut by hand.
How to install a cistern on a toilet
After the silicone has completely hardened and the cistern drain mechanism is assembled, you can proceed to install it on the toilet.
Between the drain tank and the base of the toilet bowl, it is necessary to lay a soft gasket in the form of a ring (comes with the toilet bowl). Then slide the cistern onto the toilet so that the holes for the tie screws on the toilet align with the holes on the cistern. The connecting screws must have a plastic flat washer and a rubber cone. Insert the fixing screws into the holes of the drain tank and twist them on the other side with plastic nuts (horns). When tightening the screws, make sure that the tank is horizontal.
Screw the flexible hose that supplies water to the fitting at the drain tank. This connection does not require the use of a fum tape, since the connection will occur through a rubber gasket.
The installation of the cistern on the toilet is completed, you can open the faucet and check the flow of water, as well as see and eliminate possible leaks in the system.
Put the lid on the drain tank so that all the elements of the trigger mechanism enter the hole. Screw the release button into the hole. Check the functionality of the button. At this stage, the installation of the toilet cistern is completed.
How to install a seat and lid on a toilet
The simplest remains. Attach the seat to the toilet and thread the mounting screws through the holes. Without much effort, tighten the screws on the back of the toilet with nuts. Toilet seat installed.
Video lesson: How to properly install the toilet on the tiled floor in the toilet
Work completed. You installed the toilet with your own hands and, rest assured, you did it right!
Installation of plumbing equipment is carried out in strict accordance with building rules and regulations. Home craftsmen often experience fear of such work. This is used by service companies that request very decent money for performing fairly simple operations. Meanwhile, fixing the toilet bowl to the floor is an activity that is quite affordable for independent implementation. It is only important to carefully read the existing work technologies, choose the most suitable one, and follow all the instructions exactly.
Regardless of the chosen method of attaching the toilet bowl, installation work begins with the assembly of the cistern. The device is assembled in accordance with the instructions and fixed in place intended for it. Also, before installing the toilet, the units for supplying and discharging water must be prepared. There are several methods for attaching devices. The main selection criterion is the floor material on which the equipment will be installed. Let's take a closer look at the most common methods.
Method number 1: installation on dowels
The most practical method that allows you to install the device with the least effort and time. It is optimal for use on a flat, smooth surface, since the slightest height difference adversely affects the quality of the flush. It is preferable to use this method of fastening for lightweight compact structures, since the fixation may not be entirely reliable. Plumbers advise installing equipment on a special gasket, which you can easily make yourself from old linoleum or a sheet of thin rubber. The toilet bowl is installed on the workpiece, circled around the contour with a marker. After that, with a sharp knife or just scissors, the gasket of the desired shape is cut out.
The device is fixed to the floor with dowels or special plumbing fasteners. Fasteners usually come with new equipment. It can also be purchased from specialized stores.
Now we need to markup. We “try on” the toilet bowl on the place prepared for the equipment and draw it around the contour. We remove the device. We apply a thin layer of sealant and glue the gasket on it. This design will be the most reliable, although some masters prefer to do without a substrate at all. You can start drilling holes for fasteners. As practice shows, if you stick the gasket with high quality and choose the diameter of the drill so that the holes for the fasteners are slightly larger than it, then further installation will be much easier. This is due to the fact that the rubber backing acts as a kind of "contact spot" for the floor and the device.
It happens that it is required not only to fix the toilet bowl to the floor, but also to raise it a little. This is true if there are several devices in the apartment. Then the last one in the system needs to be raised by about 3-4 cm. In this case, a piece of a two-inch board is used, which is used as a stand. It is cut exactly along the contour of the toilet and placed on the floor, a rubber substrate is placed on top of it. All this is sealed with a sealant and forms a reliable and durable structure. Holes for fasteners are drilled directly on the gasket.
Tighten the mount on the base of the toilet very carefully. Excessive force can damage the ceramics from which the device is made.
As fasteners, you can use long metal dowels or special plumbing fixtures. The latter usually come with new equipment. The quality of fixing they have is about the same, so you can use both options. We drive dowels into the holes prepared in the floor. We install the toilet and carefully screw it. It must be remembered that excessively strong tightening of the ceramic from which the device is made can be damaged.
Now you need to connect the device to the sewer. At this stage, we pay special attention to the corrugation. We generously lubricate both its edges with silicone. We insert one of them into the sewer socket, and put the second on the toilet outlet. All parts of the connection should be carefully pressed with your fingers so that the sealing is of high quality. As an additional measure, you can use metallized tape, which can be used to seal the joints. We connect the water supply and the device is ready for operation. There is a similar mounting method, which is presented in detail in the video.
Method number 2: mounting on glue
Of all the methods for fixing a toilet to the floor, this one is the easiest, but also the most time consuming. For the curing of the epoxy mixture, which is used as an adhesive, it takes about 12-15 hours. This method can only be used on a smooth surface. Most often it is used to fix equipment on floor tiles. The method is very easy to perform. First, both surfaces to be bonded must be well cleaned of dust and debris. Floor tiles can be sanded to make them rougher. This will improve the adhesion of the material. Surfaces are degreased with any solvent or acetone.
Preparing glue. You can buy ready-made epoxy or make your own. To do this, you need to take 100 parts of epoxy resin ED-6, 200 parts of cement, 20 parts of solvent or plasticizer and 35 parts of hardener. The order in which the components are added to the solution is important. First, the resin is heated to 50C, a solvent is added to it, then a hardener, and at the very end - cement. The composition must be constantly stirred to form a plastic, homogeneous mass.
In order for the toilet to be securely fixed in place, the floor covering is prepared: cleaned for better adhesion and lubricated with a small layer of glue. Excess composition, speaking under the weight of the equipment, is immediately removed with a damp cloth.
Properly prepared adhesive mixture can be used within one and a half hours. We apply it to the base of the toilet bowl so that the solution covers an area of at least 20 square meters. cm, and the layer thickness was at least 4 mm. We install the prepared equipment in the right place, combining the sewer socket with the outlet, and press it to the floor with force. After that, the device is left for at least 12 hours. This period is necessary for the curing of the adhesive composition. During this time, it is not recommended to even touch the toilet. Then we connect the equipment to the water supply and sewerage.
Method number 3: taffeta mount
Most often, this method is used to install toilets on a wooden floor. Taffeta is a pad of durable wood to which equipment is attached. The thickness of the board from which the element is cut, corresponding to the shape of the toilet support rack, should be 28-32 mm. To protect the part from dampness, it must be carefully treated with drying oil. For reliable fixing to the floor from the bottom of the taffeta, an anchor is mounted. The simplest option is nails driven in a checkerboard pattern, which should protrude 2-3 cm from the part. The recess prepared for installing the toilet bowl is filled with cement mortar. Taffeta is sunk down into it with anchors. As a result, it should be flush with the floor.
After approximately 12 hours, during which the mortar is completely dry, you can proceed to fixing the equipment. The device is fixed with screws. Rubber washers must be placed under their heads, which will prevent possible damage to the toilet frame when tightened. Experts advise lubricating the screws with grease or graphite before work, so that later, if necessary, they can be easily unscrewed. Wood taffeta can be replaced with a rubber backing. It is cut out of sheet material with a thickness of 5 to 15 mm, possibly even from an old rubber mat. Such a substrate should be 1-2 cm smaller than the toilet support column.
Mounting the toilet on taffeta involves the use of a special wooden insert. The diagram shows all the elements of such a mount.
There are various ways to attach a standard toilet bowl to the floor. They differ significantly in complexity and time spent on installation work. It is important to choose the right fastening method. It depends on the material from which the floor is made in the room. Installation work can be carried out independently, but if there is no experience or desire, it is better to turn to professionals. They will quickly and competently carry out all the work, guaranteeing a long and flawless service of the new equipment.
According to the current SNiP, the installation of plumbing equipment (including the toilet) is carried out in compliance with certain rules, which guarantees a long operating time. Many companies provide installation services, but you can do this operation yourself and save decent amounts.
Before we figure out how to attach the toilet to the floor, let's get acquainted with their known types and find out the design features.
Toilets differ in the following characteristics:
- the device of the tank and the drain bowl, the method of their articulation;
- sewage flow direction (direct or lateral);
- the material from which the toilet is made;
- dimensions and total weight.
When considering the installation of toilets in this class, the focus is on the first point (that is, design differences).
Reliable fastening of the toilet bowl to the floor can be obtained provided that its design features are taken into account.
These plumbing samples are of two types:
- models with a tank, which is mounted on the ledge of the bowl from its back side
(the water tank is adjacent in this case directly to the wall of the toilet);
- monoblocks, in which the bowl and drain tank are made as one module, do not
with detachable parts.
The advantage of the combined version or monoblock is the ease of maintenance of the toilet, including its repair. To this should be added the relatively low noise of the flushing procedure in comparison with a typical separate design.
The disadvantages of this class of plumbing fixtures include a noticeable decrease
pressure of the drain mass.
Let's figure out how to fix the toilet bowl to the floor in the toilet.
There are three methods:
- mounting on dowels (bolts),
- on glue
- taffeta fixation.
Let's consider each of these toilet attachment methods in more detail.
Mounting with dowels (bolts)
This method is the most practical and does not require large expenditures. He also
provides a secure mount for the toilet, provided that the floor screed
prepared for installation.
Small irregularities do not impair the tightness of the installation, since in this case an elastic gasket can be used.
Fixing the toilet bowl to the floor with bolts is suitable for both conventional structures and
light, compact, that is, this option can be considered universal.
Bolts for fixing the toilet to the floor allow you to get a tight connection,
if a sealing gasket cut from a piece of linoleum is used
or elastic rubber.
These blanks are placed under it, and then outlined along the contour with a marker. Immediately after this sharp knife (sometimes scissors are used for this), a sealing element is cut out, corresponding in shape to the supporting part of the product.
Before fixing the toilet to the floor, markings are made on the surface of the screed
specially for dowels, into which the hardware is then “driven”. The latter are usually included
included with the device to be installed. In their absence, special bolts for
floor mounts are available from a hardware store.
The order of further operations looks like this:
- First, a purchased toilet is placed on an already prepared place for fitting, and
then outlined along the contour with the same marker. - Then the toilet is removed, and the marked place is coated with a sealed composition,
on which the previously prepared gasket is glued.
Additional information: in some cases it is possible to do without sealing, but for this the floor surface in the toilet must be well leveled beforehand. - Before attaching the toilet to the prepared surface, you need to
prepare holes for metal dowels, for which a drill with
diameter slightly larger than the size of the hardware. - Then the same holes are made at pre-marked points.
glued pad. - Now it will be possible to hammer the dowels into them and carefully install them on the gasket
toilet for subsequent fixation. - Bolts for fixing the toilet to the floor should be screwed in very carefully, without
efforts, being careful not to damage the ceramics.
Violation of this rule when handling tools and hardware can lead to
the appearance of cracks or chips in the attachment points.
This is unacceptable - the bowl will then become unusable. After fixing, they proceed to the connection to the sewer, paying special attention to connecting the corrugation of the drain channel.
To form a tight connection, its ends are liberally lubricated with silicone,
one of them is inserted into the socket of the sewer outlet, and the second is put on
outlet neck. In the course of installation, the joints are carefully crimped with palms,
which will allow the hermetic composition to quickly soak into the material of the corrugations and form
reliable contact.
To obtain a tight connection, the place where the toilet is drained can be additionally sealed with metallized tape.
At the end of all these operations, it's time to connect the plumbing
outlet, and the plumbing fixture is completely ready for work.
Glue fixation
A reliable mount for the toilet can also be designed with the help of an adhesive composition,
bought ready-made or prepared with your own hands.
This method is considered the simplest, but at the same time fastening without bolts will require a lot of time (it takes 12–15 hours for the epoxy adhesive to fully cure).
Another condition for obtaining reliable fastening is as follows. Before as
glue the toilet to the floor, you will need to carefully level the surface of the screed or
cover it with thick floor tiles.
When figuring out how to glue the toilet to the floor or tiles, preference is usually given to special epoxy resins, prepared according to the instructions attached to the composition.
The method of attaching a sanitary ware to the adhesive composition is simple, for this
you will need to do the following preparatory operations:
- First, the working surfaces are cleaned of dust and dirt residues.
Before gluing the toilet on the tile, it is desirable to give it a small
roughness, for which you can use a large sandpaper - this technique helps to improve the adhesion of the surfaces to be glued.
- Then they are degreased with a solvent or ordinary acetone, then
you can proceed to the preparation of the glue. It can be bought in the store ready-made
or cook it yourself.
To do this, you will need: 100 parts of ED-6 resin, 200 parts of high-grade cement, 20 parts of solvent and 35 parts of hardener.
When preparing the adhesive composition, the sequence of actions is important, which determines
the order in which individual components are added to it.
First of all, you should heat the resin to 50 degrees, and add a solvent to the thick solution. It is followed by the addition of a hardener and at the very end of the procedure cement is placed there. In the process of adding the components, the mixture must be continuously stirred, as a result of which a homogeneous and dense plastic mass should be obtained.
For better fixation of the plumbing fixture on the screed or tile of their surface
pre-cleaned and lubricated with a not very thick layer of prepared adhesive
mixtures.
Upon completion of installation, excess epoxy composition up to 4 mm thick, squeezed out by the mass of the device, is immediately removed with a damp cloth.
It is advisable to use the mixture prepared for installation within one and a half hours. Otherwise, it will freeze and become unusable.
When installing a toilet bowl, you should carefully ensure that its socket is located strictly opposite the sewer drain hole. If this is not observed, you need to forcefully press the base to the floor.
Upon completion of these operations, the device is left for about 12 hours, necessary for the final curing of the adhesive. After the specified time, you can proceed to connecting it to the water supply and sewerage.
Taffeta fastening
When choosing fasteners for a toilet bowl to the floor, take into account the possibility of mounting it on a wooden floor, which is usually required in private buildings. In this case, you will need a special gasket made of durable wood (it is called taffeta).
For its manufacture, a board 28–30 cm thick is taken, corresponding in size
the form of a toilet stand. In order to protect against moisture and destruction of its surface
covered with a layer of drying oil.
