The variety of finishing building materials on the market opens wide horizons for homeowners. This factor has long been the reason for the growing popularity of ceramic tiles. Wall and floor ceramics are used for decoration of toilets and bathrooms.
The result of this finish is impressive, but in this case, every owner inevitably has to decide the question - how to install the toilet on the tile and fix the device without damage to the created interior.
What is the peculiarity of mounting the toilet on the tile?
The procedure for installing plumbing in itself is no different from standard options. The difficulty lies only in the fact that the installation of any toilet on the tile automatically gives rise to the problem of fasteners.
The natural moment - on a smooth slippery surface it is not easy to “tightly” fix a household appliance weighing more than ten kilograms.
A properly installed toilet on a tiled floor gives a complete finish to the interior of the toilet room. A masterful approach to the installation process, taking into account all - even the smallest details - allows you to do the job with high quality. And it’s not at all necessary to have professional experience, you can do it yourself
But along with the technologies for the production of ceramic tiles, the technologies for manufacturing fasteners are also being improved. Therefore, a difficult, at first glance, task of installing a toilet on a tile is solved in any case. The main thing is to get acquainted with the installation methodology and correctly apply it in practice.
There are several methods for installing plumbing on a tiled floor with subsequent reliable fastening:
- by tightening with fixing screws;
- using specialized adhesive pastes;
- by traditional cementing of the base.
Regardless of the method of installing the toilet on the tiled floor, the main rule always remains relevant - caution and accuracy in the work. The tile does not tolerate rudeness. Any careless movement threatens to turn into trouble.
Method # 1: screw fastening
The design of all types of toilets (except for exclusive models) provides for the manufacture of holes for fasteners. These holes are located at the bottom of the instrument, just above the sole plane.
Almost any toilet has special mounting holes in the housing. Most products contain one hole on each side
But there is also a considerable proportion of toilets, the design of which is designed for fastening with four screws (2 on each side). Usually these are large models with significant weight.
In order to fix the toilet on the tiled floor with fixing screws, we perform the following steps:

We put the toilet in the assembled state in the place intended for its placement. We determine the length of the sewer pipe, if necessary, we move the plumbing
Taking into account the approach to the release of the toilet bowl and the pipe of the sewer system, we cut off the pipe. We try not to make mistakes when cutting
Before connecting the toilet to the outlet into the sewer, we mark the points at which the fixation will be made
Using a core, we punch holes in the floor at the points at which the markings were made. Punching is done so that the fixing barrel does not warp during fixing
In order to prevent the tiles from cracking and cracking during hole drilling, we glue the points with masking tape
We drill holes in the glued points with a drill, the diameter of which is equal to the diameter of the mounting plugs attached to the toilet
We put the toilet into place so that the holes in it coincide with the mounting plugs installed in the drilled holes. We tighten the screws with the obligatory use of polymer washers between the hat and the toilet
We install fittings in the toilet flush tank. We connect the hose from the water supply, open the water and check the plumbing
Step 1: Fitting the toilet to the wall and installation site
Step 2: Cutting the drain pipe
Step 3: Perform marking for toilet mounts
Step 4: Punching holes for core fasteners
Step 5: Pasting the points with masking tape
Step 6: Drilling holes for mounting plugs
Step 7: Fixing the toilet with fixing screws
Step 8: Connect the toilet to the water supply
Tile marking and centering
If the task is how to install a toilet bowl of any of the marked configurations on the tile, the main part of the solution is the preparation of holes for dowels (plugs). But how to make holes in the ceramic tile without damaging this fragile material?
A special drill for ceramics and Malomalsky experience with a drill will help here. But first, the master needs to mark the installation location and mark the fastener points.
The best way to accurately markup is to temporarily move the plumbing to the installation site. Already in place, the device is centered in all directions, taking into account all the connections
Then, directly on the tile, draw a marker with the border of the sole by contour along its contour. Next, the points of the centers of the mounting holes are marked. After completing the markup, the toilet is removed.
Core and tile drilling
The next step is a small core at points pointing to the centers of future holes. The core is performed by a well-sharpened punch. The point of the center punch is directed to a point and a few very weak blows are applied to the butt plate of the tool with a light hammer.
The goal is to chop off a layer of polished tile and get small holes with a radius of not more than 2 mm. This work must be done very carefully.
The option of drilling holes for installing the toilet on the tile when using the so-called tubular drill. In fact, this is a small diameter diamond crown, thanks to which the mounting holes are drilled in a few minutes. There are also special spear drills for tiling.
Having received small holes on ceramics, they take a drill, and a special drill for tiles is tucked into the cartridge. You must use a drill with the function of the engine speed controller.
Tile drilling only at low speeds. In the process, it is recommended to periodically water the drilling area with a small amount of water. In this case, we must not forget about the rules of electrical safety.
Drilling holes in the tiles is carried out to the border of the cement screed. Then the drill bit on the tile is changed to a drill bit for concrete, and the electric drill for a perforator.
The diameter of the drill should not exceed the size of the diameter of the drill on the tile. Using such tools, drill holes in concrete to the depth of the mounting screws and press in stop plugs (dowels).
Sealing and screwing in screws
At the final stage of installation, the following actions are performed:
- The sole of the toilet is treated with a thin layer of sealant.
- Place the toilet exactly on the previously marked track.
- The fixing screws are equipped with gaskets.
- Insert the screws into the mounting holes.
- Screw in all the way with a tightening 1-2 turns.
Do not overtighten the screws. So you can damage the sanitary ware.
Method # 2: glue mounting
The method of gluing toilets is usually used when there is no possibility of using fasteners on screws. For example, the plumbing configuration does not allow or the homeowner simply does not want to violate the integrity of floor ceramics.

Step 1: Floor Marking the Location of the Toilet
Step 2: Preparing the toilet base for gluing
Step 3: Gluing Plumbing to the Marked Place
Step 4: Fastening the toilet and connecting communications
There are various technical brands of glue and paste that can provide quite reliable fastening:
- silicone sealant;
- liquid Nails;
- Pastes of the Fix All series;
- epoxy resin.
How to perform the procedure? The installation method on the adhesive in terms of complexity of execution is much simpler than the method of mounting on screws. However, the sequence of the procedure actually repeats the technique with the screws.
Here, the main factor is the preparation of mounting bases directly on the tiles and on the bottom of the toilet.
The result of unprofessional do-it-yourself work when the toilet was seated on epoxy glue. Under the glue layer, traces of rough processing of the seat, poor-quality cleaning of the surface of the tile are visible. It is extremely difficult to eliminate such a defect, so initially you need to approach work with all the nuances
Surface preparation and treatment
Marking of installation boundaries is performed in the same way as in the previous installation scheme. Plumbing is placed in the place where the toilet is supposed to be fixed to the floor, and the interface area is outlined.
It is desirable to roughen the surface of the tile area where the sole of the toilet lies. To do this, you can use large sandpaper. Be sure to degrease the surface with white alcohol or similar substances.
To obtain a high-quality reliable connection, the working surfaces should be leveled, cleaned. It is desirable to process the tile with large emery and carefully treat it with a degreasing agent. The same steps should be taken with respect to the sole of the toilet.
On the outside of the marked border, glue the tiles with masking tape (protection of the tiles from glue).
Bonding plumbing device
After the working surfaces of the tile and toilet bowl are ready, you must perform the following steps:
- Apply glue evenly on the sole of the device.
- Carefully put the toilet in its "native" place.
- With a small periodic force (10-15 seconds), press the plumbing to the floor.
- Remove residual adhesive material along the outsole.
Installed plumbing must be allowed to stand for at least a day without applying any action to it. This time is enough for the adhesive to transfer to a state of solid reliable fastening.
All that remains is to remove the protective masking tape and after 3-5 days you can begin to fully operate the plumbing fixture.
A positive result of gluing the toilet on the tile floor. In this case, a silicone sealant was used as a bonding component. In some places of adjoining, small gaps are noted, but they are easy to hide if you “walk” along the contour with a gun and carefully cover it with the same sealant to match the color of the toilet
The use of technology with adhesives is not recommended if it is possible to use the standard option of fixing the toilet to the floor - mounting on bolts. With all the advantages of adhesives, it is extremely difficult to choose the perfect composition for glossy surfaces.
But if such a method has already been chosen, it is worth paying special attention to the preparation of glued surfaces. In addition, it is recommended to select the optimal glue by the method of test bonding of test materials.
Method # 3: cement clip
On a tile floor, a plumbing fixture in the toilet can also be installed using cement mortar. Such a technique is practiced in individual cases, and it has shown quite acceptable results.

Step 4: Fixing the toilet to the floor with fixing screws
The technology of "landing" on cement, however, requires careful preparation of the working surface of the tile. In particular, it is necessary on the working area (the landing area of the bottom of the toilet bowl) to make notches, cuts, bully (create a corrugated surface).
Reliable adhesion to the cement mortar is provided by preliminary preparation of the surface of the tiled floor in the place where the toilet sole “lies”. But making notches on the tile should be done carefully. With such actions, there is a risk of damage (split) of the tile
Perform this work with a hand tool (chisel, punch) or power tool (grinder, grinder). The option of drilling shallow holes on the tile throughout the working area is not excluded.
Creating a corrugated surface at the place where the toilet is bonded to the tiled floor will provide better contact of the cement mortar with the tile. The stability of the plumbing installed on the tile is thus achieved up to the level of attachment with special adhesives.
Preparation of ordinary solution
A cement mortar is usually prepared on the basis of a mixture of cement with quarry sand in a ratio of 1: 2. Initially, being dry, both components are thoroughly mixed.
Then, water is added to the container with the resulting mixture in small portions with constant stirring. In total, the volume of poured water should not exceed one third of the mass of cement in the solution.
So get a cement mortar for fastening the toilet with tile.
Properly prepared cement mortar will ensure reliable fastening of plumbing to the floor. It is necessary to maintain the proportions of the components and dilute them with a strictly defined amount of water
Final installation steps:
- Moisten the work surfaces (floor and sole of the toilet bowl) with water.
- Cover the working area of the floor within the boundaries of the sole of the device with cement mortar (layer thickness 7-10 mm).
- Put the toilet in the place of dislocation and with a small effort briefly press it to the floor.
- Remove excess mortar with a spatula at the borders of the landing.
- Keep the installed device in a calm state for at least 24 hours.
To fully use the toilet should begin no earlier than 3-5 days.
Liquid Glass Cement Mortar
The practice of cementing toilets on tile floors does not preclude the use of upgraded cement mortars.
So, in a plumbing installation, a solution was tested and showed good results, where along with cement and sand there is liquid glass. But various options for obtaining such solutions showed that only with a ratio of cement to water glass of 1:10 it is allowed to use a solution for installing toilets on a tile.
Liquid glass can be used as an additional component to cement mortar for installing the toilet on the tile. This additive enhances the adhesion properties of the solution, makes the connection stronger. However, these properties are achieved only if liquid glass is added to the solution without excess
Meanwhile, the technology for the preparation of cement mortar containing liquid glass has its own characteristics. For example, water glass cannot be mixed with already prepared cement-sand mortar.
The admixture is previously diluted with water and the dry cement-sand component is diluted with the liquid already obtained. When working with liquid glass, safety precautions must be observed.
Instructions for installing and connecting a toilet with an oblique outlet are given in the following article, the contents of which we recommend to familiarize yourself with.
Here you will find everything about installing toilet bowls, including on tiled floors:
Installation of plumbing fixtures in the toilet on the tiled floor is possible. This fact is confirmed by several installation methods, each of which has been tested in practice and successfully applied.
Another issue - the choice of a particular tile installation technology must be compared with the load parameters that are supposedly possible during the operation of plumbing fixtures.
