Equipping modern housing with a toilet room is a traditional touch of any project. In turn, installing a toilet in a toilet is also a well-established procedure. Usually the default installation is carried out during the construction of housing.
We will tell you how to fix the toilet to the floor. Together with you, we will figure out which method of fixing plumbing is better to use if you suddenly have to change the device during operation. Based on our advice, you can quickly and easily perform work without involving plumbing.
Technical details of plumbing installation
A toilet bowl of any configuration, like a plumbing fixture as a whole, is mounted in accordance with the installation instructions. The initial installation of these plumbing fixtures (at the stage of housing construction), as a rule, is carried out by professional performers.
But in the future, already held property owners often carry out the reconstruction of the toilet, in particular, change the toilet. And they do it on their own in order to save on installation services.
Users often change equipment to suit their personal preferences. Some of them do not possess all the nuances of installation and methods of attachment.
Installation of the toilet with subsequent attachment to the floor of the toilet room. The initial installation of such plumbing is usually carried out by professional plumbers
Self-reinstallation is not prohibited and welcome. However, such intentions of the owner should at least be accompanied by knowledge of how to fix the toilet to the floor. It would seem to be a banal detail of the installation procedure, but when the result they want to see a high-quality, reliable installation - even the smallest details are important.
The nuances of installing toilet bowls are directly related to the type of plumbing fixtures chosen for installation. In everyday life, floor-mounted toilets are most often used. Moreover, most of the mounted devices have the configuration of compact products.
How to fix a compact and any other toilet to the floor of the toilet room, performing the installation yourself?
Compact model of the toilet, mounted according to the mounting scheme to the floor. In this case, the installation is done professionally. High quality installation and fastening of plumbing on the floor is clearly demonstrated
Approximately to such a result, self-taught masters should strive.
Analysis of fastener methods
Construction practice indicates at least three methods of attaching toilets to the floor surface:
- standard installation kit;
- by using special adhesives;
- by installation on a cement mortar.
A standard installation kit (dowel-screw) is usually recommended if installed on an exceptionally flat floor surface.
The method, from the point of view of reliability and stability of the structure, is considered acceptable, but does not fully satisfy in all cases. We apply the “standard” usually to models of a compact type, which are light in weight and modest in size.
Another way to fix the toilet to the floor - landing on glue - provides a high level of bond strength. But in this case, the quick dismantling of the product if necessary is excluded. Therefore, the installation method for glue is used, where installation involves the continued use of plumbing without the prospect of replacing it.
The procedure for installing and attaching the toilet to the floor by the method of planting the sole of the device on glue. For gluing, as a rule, special adhesive pastes and solutions are used.
Often, epoxy is used as glue. This glue is distinguished by high characteristics in terms of reliability and fastening strength.
Cement mortar is often considered as an alternative to standard and adhesive techniques. In fact, this method is not much different from “sticking to glue,” since cement contains an adhesive component. Meanwhile, the connection of the toilet to the floor with a cement mortar shows a lower degree of strength compared to special adhesives.
The choice of mounting method to a large extent depends on the type of base on which the installation is made. You will learn about how to put a toilet on a wooden floor from an article that details this issue.
Technology for fixing the toilet to the floor
When referring to a particular method of attaching a home appliance to the floor, the master will need a certain set of tools.
Usually, work is carried out without much difficulty, when at hand there are:
- construction punch (plus a set of drills of different diameters);
- hand drill (plus drills of different diameters for ceramics);
- manual mechanical press (pusher gun);
- screwdrivers, metalwork wrenches, pliers, hammer;
- tape measure, pencil, core, rubber spatulas (wide, narrow);
- sandpaper (large, small).
Possible materials for installing plumbing:
- plastic dowels (d = 8-12 mm, 2-4 pcs.);
- metal screws (screws) (d = 6-8 mm, 2-4 pcs.);
- gaskets under the screw head (2-4 pcs.);
- glue (liquid nails, silicone, epoxy);
- cement, quarry sand (at the rate of 1: 2);
- wooden board (thickness 20-25 mm);
- sheet rubber (thickness 10-15 mm).
Installing the toilet and fixing this type of plumbing to the floor with standard fasteners involves drilling holes for dowels. If the configuration of the plumbing fixture is made for fastening with two screws (screws), two holes need to be drilled. In the other case, respectively, four.
One of the methods for fixing the toilet to the floor is to fit the device on screws (bolts, screws). This mounting option is used in practice more often than others. Usually the lion's share of all manufactured toilets is equipped with just such fasteners
The drilling process is accompanied by some difficulties when a toilet is placed on a tile. Careless action, lack of experience, ignorance of the technology of drilling holes in ceramic tiles are the main causes of installation failures. Ceramics need to be drilled with a special drill, observing the rule of light pressure and low speed of rotation of the drill.
Installation with subsequent mounting on a cement mortar also has its own characteristics. Here, an important factor determining the quality of the compound is the composition of the solution. Therefore, it is recommended to adhere to the established ratio of 1: 2 (M200) as precisely as possible, where the first digit is the amount of cement, the second is the amount of quarry sand.

Step 1: Preparing the floor after removing the old toilet
Step 2: Installing the toilet to try on
Step 3: Install the sewer pipe
Step 4: Fixing plumbing with fixing screws
With this ratio, the brand of cement solution is obtained - M200, which is optimal for domestic use.
The technique of installing toilet plumbing, where cement mortar is used as a connecting link. The method is almost similar to "landing" on glue
Cement mortar fastening is not often practiced in modern construction conditions.
Step-by-step screw mounting process
If the first option for fixing the toilet to the floor of the toilet room (standard with screws) is selected, the following steps are performed:
- The exact location on the sole floor of the plumbing fixture is determined.
- Marks the centers of the mounting holes on the surface of the coating.
- A drill for ceramic tiles at the marked centers drills holes with a depth equal to the thickness of the tile.
- Using a drill on concrete, the holes are drilled to the desired depth (usually 60-70 mm).
- Dowels from the mounting kit are inserted inside the holes obtained.
- Plumbing is placed at the installation site, the mounting holes of the device are combined with the holes made in the floor.
- The outlet pipe of the toilet bowl is connected to the sewer system with a corrugated hose.
- The screws from the mounting kit fix the device to the floor.
After these works are completed, the connection points of the corrugated pipe to the toilet and to the sewage system are additionally sealed. For these purposes, a sealant or similar means is used. Cosmetic sealing of cracks is also performed along the axis of pairing of the sole of the device with the floor plane, if any.
Installation of a corrugated pipe - an element for connecting the toilet drain line to a centralized sewage system. The corrugation connection and the subsequent sealing of the joints are carried out after the plumbing is fixed to the floor. This sequence is logical. It eliminates the risk of damage to the sealant layer due to vibration.
The installation of the toilet bowl and its attachment to the floor in the second way are considered as simplified as possible. Here, the master-do-it-yourself master does not even need skills or knowledge regarding drilling various kinds of building materials.
All that may be required is an instruction manual for working with a manual mechanical press (push gun). And when epoxy is taken as glue, installers are completely dispensed with without a “gun”.
The process of installing and securing the toilet with screws involves a number of traditional steps:

Step 1: Purchase a toilet bowl and related parts
Step 2: Choosing a place and preparing sewer pipes
Step 3: Assembling the Sewer Connection Node
Step 4: Drilling holes for securing the toilet
Having successfully completed the preparatory work, we proceed directly to the installation and fastening of an important household appliance:

On top of the drilled holes we lay a shock-absorbing pad, for example, penoflex or a thin sheet of silicone, install a toilet bowl, put fasteners in the mounting holes of the toilet bowl
Screw the screws into the floor until they stop, but do not apply excessive force so as not to damage the earthenware product
Carefully with a construction knife, cut the seal on the outline of the toilet bowl legs, taking care not to scratch the tile, remove excess material
From the fastening bolts designed to fix the tank to the toilet, we unscrew the plastic nuts
Install the drain valve and mounting bolts into the holes in the bottom of the tank
We twist the plastic nuts, fixing the tank to the toilet. We connect a hose to the tank, which we will connect to the water supply
Using a tee, we connect the hose to the cold water pipe. Do not forget about winding plumbing thread
After connecting the toilet to the water supply, open the overhead tap, check the plumbing, the tightness of the connections and the flushlessness
Step 5: Installing a cushioning pad under the toilet
Step 6: Fixing the toilet to the tiled floor
Step 7: Cutting the seal on the toilet outline
Step 8: Preparing Tank Mounts
Step 9: Installing the mounts in the bottom of the tank
Step 10: Fixing the tank and connecting the hose
Step 11: connecting to the water pipe
Step 12: Checking the operation of the toilet and the drain
Bonding the toilet to the floor
Work on fixing the sole of the device to the floor with special glue is performed in the following sequence:
- Accurate layout of the toilet seat.
- Preparation of the sole of the device (cleaning, leveling, degreasing).
- Application of adhesive mass to the surface of the sole.
- Installation of the device exactly at the previously designated boundaries.
Under the weight of the plumbing, excess glue will inevitably appear along the outer edges of the sole. These surpluses are cleaned with a rubber spatula, after which the exit area of the adhesive residues is additionally wiped with a rag soaked in soapy water.

Step 1: Marking the place to stick the toilet to the floor
Step 2: Putting glue on the base of the toilet
Step 3: The process of gluing the toilet to the floor
Step 4: Fixing with screws and connecting communications
After completing the procedure, leave the plumbing for a day until it is completely fixed due to the drying of the adhesive mass.
About the same algorithm, work is performed when the method of fastening to cement mortar is selected:
- A small amount of cement solution is prepared.
- Markings are being made for installation on the floor of the toilet room.
- The installation site is thoroughly cleaned of debris and dust.
- A uniform solution layer is laid out at the installation site.
- The sole of the toilet is wetted with water, then the device is placed on cement.
- Excess cement slurry is removed with a spatula.
An exposure time for full fixing for this option is also recommended for at least 24 hours. Then you can perform additional actions - pairing the drain with the sewer, installing and fixing the tank, installing the toilet seat.
Before you start installing the toilet, the location of the device is marked on the floor. The marker also marks the centers of the holes available on the bottom of the toilet and designed for mounting plumbing. All measurements and mounting marks are made as accurately as possible, after first placing the toilet in the place of future installation
The choice of the connection scheme of the toilet to the sewer is determined by the type of release of the device. Connection options are described in detail in our recommended article.
Other mounting methods
There is another way to fix the toilets on the floor of the toilet rooms. The technology is called “installation on taffeta”.
Due to its antiquity, this technique quickly loses its relevance, but sometimes it is still used, but, as a rule, on wooden floors. The principle is to attach a plumbing fixture to a wooden board - taffeta, carved according to the shape of the sole.
The method of mounting the toilet "on taffeta". Here, the support for the sole of the plumbing is a wooden board trimmed exactly to the shape of the sole of the toilet. First of all, the taffeta itself is fastened, and then the toilet is fixed to it with screws
On the floor of the room, at the place of installation of the plumbing, a shallow recess is made (up to 50-70 mm deep). This recess is filled with cement mortar. They take taffeta and randomly pierce it over the entire area with nails. On the other side (bottom), where the nails came out, taffeta is laid on a cement pad.
On the outside of the taffeta, a toilet bowl is installed and fixed. Of course, this is done after the cement mortar has completely set. Fastening is carried out according to the standard - with screws.
A kind of counterweight to the outdated technology of attaching "to taffeta" is perhaps the most modern technique - fixing plumbing on a support frame - installation.
Modern technology for fastening the toilets of a home toilet. The fixture of all toilet elements is carried out on a special metal frame - installation disguised in the wall
True, “installation” is a metal structure, it already provides for a slightly different form of installation - suspended. That is, plumbing is not mounted with emphasis on the floor of the toilet room, but remains after installation in a suspended state.
Note to installers: helpful tips
Plumbing fixtures are made from strong but fragile materials. Therefore, fixing a porcelain or earthenware device with screws (bolts), it is not recommended to use maximum efforts for screed. Be sure to use soft pads (silicone, rubber, plastic), placing them under the screw heads.
Attach the toilet bowl to the metal screws carefully with moderate force. Soft gaskets are strongly recommended under the screw heads.
If glue is used for fasteners, the quality of cleaning and degreasing the surfaces to be bonded is of great importance in achieving bond strength.
Using epoxy resin, it is necessary to clearly observe the ratio of resin and solvent during the preparation of the adhesive mass. On the surface, glue must be applied evenly, to prevent the formation of air cushions.
When installing the device “on taffeta”, it is desirable to choose hardwood as a material. You can use multilayer plywood, but in any case, you should provide high-quality waterproofing for taffeta. A humid environment dramatically reduces the durability of any wood.
One of the options for attaching a plumbing fixture to the floor is discussed in the following video:
Which method of installing toilets is best is up to the property owner to decide where to install and fix the plumbing.
However, choosing a methodology, it is recommended to take into account possible loads on the toilet, the material of the device (faience, porcelain), as well as the design features of the toilet room. A careful approach to business will certainly help to achieve the desired result.
