How to strengthen the toilet if it wobbles - Instructions + Video The toilet is swinging - how to strengthen it + Video. Some of the plumbing fixtures, due to their long service life, start to perform worse than before. One of the most common troubles associated with the toilet bowl is its fragile fixation, which makes it extremely inconvenient to use the device (there is a chance of falling). How to strengthen the toilet if it wobbles? You can do it yourself, especially if you have at least basic skills in handling various tools.

Let's look at all the possible solutions to the problem.

Features plumbing installation

Plumbing fixtures, and in particular the toilet, are installed based on the installation instructions that are attached with the purchase. During the construction or overhaul, such work is carried out by professional plumbers, but in the future, after moving in, most residents want to make their own adjustments to the sanitary unit device, therefore, they replace the original toilet bowl with a new one that they bought themselves.

In order to perform such work with high quality, it is imperative to know what methods are available for fixing the device on the floor covering, as well as how to use them correctly. All the features of the installation of a plumbing fixture will be directly related to the configuration of the plumbing. As a rule, in a household sanitary unit, only compact models are used that are installed on the floor, and the fastening of such devices is different.

Why the toilet is loosening

Before fixing the appliance on the floor covering, it is imperative to determine the reason why the plumbing is loose.

Usually there are several reasons, but they can be combined into the three most basic and popular:

The flooring in the sanitary area is usually a concrete backing, but there are also options with wood finishes.

Due to the loss of the tightness of the fastening screw during operation, the fixed toilet bowl on the wooden covering begins to loosen, and sometimes cracks appear in the areas where everything is attached with screws. It is from this that the loss of stability is most often obtained.

Also, sometimes the surface of the concrete screed was poured, but with some violations, which can lead to deformation, a drop in floor level in height. From this, the toilet begins to "walk". In special cases, the reason for the unreliability of the fastening may be the failure to comply with the installation technology of the plumbing fixture.

Overview of installation options

How to fix plumbing fixtures to a wooden floor

If the floor in the bathroom is made of wooden planks, then the toilet is , which sways, it is quite possible to fix it, but it is not reattached to the damaged area.It will be more correct if you move the device a little to the side and screw it in a new place. At the same time, we recommend that you drill holes for secure fixation, the location of which will coincide with the holes for the fasteners and fasten with screws. Do not try to tighten loose screws in the old place, especially if the floor is made of planks. The problem is that this can lead to further cracking of the instrument.

To make the installation easier, it is better to make the connection to the sewer system from the toilet bowl flexible.

How to fix a toilet to a concrete floor

It is actually much more difficult to fix the problem if the flooring has a concrete base. In old buildings dating back to the times of the USSR, the devices were installed on a concrete floor, which has embedded boards.

In such a case, in order to improve the fastening, follow these steps:

  1. Shut off the water supply to the sanitary fixture (toilet).
  2. Remove the drain tank.

  3. Disconnect the drain pipes.
  4. Remove the bolts that secure the plumbing fixture to the floor.

Please note that the rest of the work should be done with extreme caution so that you do not inadvertently damage the fragile material of the old toilet bowl.

To eliminate the breakage, you should remove the old mortgage board, and in its place put a layer of new sawn timber, which will be thicker than the previous one. You can also bore the area and concrete it.

After the concrete has hardened, install the plumbing in the following order:

  1. Place the toilet in the desired area, mark the points where it will be attached.
  2. Remove the plumbing fixture, make holes in the marked place with a puncher.
  3. Fasten the toilet with the bolts.
  4. Reinstall the drain tank.
  5. Connect the plumbing and sewer pipes with a corrugated hose.

Now let's talk about the features of installing a toilet on the floor, which is finished with tiles.

Installation on ceramic tiles

In modern apartments that are located in a new building, the floor in the sanitary unit is usually made of tiles. In this case, the device will have a backlash if the tile was not laid out according to the level, and also has drops. It is most difficult to eliminate such a defect, since it will be necessary to get rid of the wobbling of the device by eliminating the unevenness of the floor. It is almost impossible to do this without removing the tiled coating.

For this reason, the problem is solved by placing a plastic gasket under the base of the sanitary fixture. Such devices are always on sale in hardware stores or in the market, and they cost a penny. If this option does not give the desired result, and the shakiness remains, you will need to disassemble the tiles and lay out the coating again.

Please note, that sometimes silicone sealant is used as a gasket, which is used to coat the area of ​​the floor covered with tiles, and where the device should be placed. When the material is completely dry, install the toilet.

This method will only help for a while, but solve the problem with a wobbling toilet.

How to attach to the floor

If your toilet is swinging, how to attach it?

To perform quality work, the master will need Use the following tools:

  • Construction hammer, which has several drills with different diameters.
  • Hand drill and a set of drills with different diameters for making holes in ceramic tiles.
  • Sandpaper with different grain sizes.
  • Spatulas made of rubber with different mixes.

  • Mechanical press (manual).
  • Locksmith wrenches, screwdrivers and other tools.

Additionally, you need to collect the following materials:

  • Metal screws or wood screws.
  • Dowels (plastic) with different diameters.
  • Construction adhesive composition.

  • Several spacers for the screws.
  • Sand, cement.
  • Planks that are 2.5 cm thick.
  • A rubber sheet with a thickness of 1.

    5 cm.

Standard toilet fixing will involve drilling holes in the floor for installing dowels. In this case, you will need to make 4 holes at once. If the attachment device is screw-oriented, only 2 holes need to be made. You may find it difficult to drill openings when the floor is covered with ceramic tiles.

The fact is that even from one awkward movement or the wrong choice of tool, the tile can easily crack.

Important! Ceramics should be drilled with special drills designed for this, and also set a low rotation speed of the device. When working, the pressure on the tool should be light.

When it is decided to attach the toilet bowl to the cement mortar, it will be correct to prepare the working mixture so that the connection is of high quality. To do this, take 1 measure of cement, grade at least M200 and add 2 measures of sand.

Fastening with screws

If the toilet is loose, how to fix it? To fix to the floor according to the standard method, follow the following steps in sequence:

  1. How to strengthen the toilet if it wobbles - Instructions + Video First, on the floor surface in the toilet, determine the exact position of the sole.
  2. Place marks in the center of the hole.
  3. Using a special drill, make grooves on the tile, the size of which will correspond to the thickness of the tile.
  4. Next, arm yourself with a concrete drill and bring the notches to a depth of 7 cm.
  5. Place the dowels into the recesses.

  6. The toilet should be positioned in such a way that it is possible to align the plumbing mounting holes with those made on the floor surface.
  7. Connect the device to the drain with a corrugated tube.
  8. Secure all plumbing fixtures to the floor using the screws provided in the mounting kit.

When all the work is done, you should additionally ensure the tightness of the connection of the corrugated pipe and the sewer inlet, as well as the toilet pipe. For this, you can use absolutely any sealant.

Next, make up the gap between the floor and the toilet bowl, if any, with a cosmetic seal.

Strengthening with adhesive

It is not at all necessary to put the toilet on the screws if it rocks for some reason. There is another qualitative way to strengthen the connection - the use of a special adhesive composition.

Work should be performed in the following sequence:

  • First, place the seat for the plumbing fixture.
  • The toilet seat must be cleaned, leveled and degreased.

  • Apply adhesive to the prepared surface.
  • Place the device on the floor, and it should be aligned with the boundaries marked in advance.

Please note, that after installation work of the toilet bowl, due to its heavy weight, excess glue may begin to protrude along the edges of the floor. Use a rubber trowel to remove any remaining adhesive. You can remove traces of tile glue with a rag that will be moistened with soapy water.

After that, the toilet can be left for a day so that the glue can finally dry out.

Installation on taffeta

This method is suitable if you need to install a plumbing fixture on a wooden floor surface. Taffeta is a kind of solid wood pad that will be placed under the appliance. From the board, the thickness of which is 3 cm, a fragment should be cut out that corresponds in shape to the sole of the plumbing. To protect against moisture, such a part must be covered with a composition such as drying oil.

To keep the taffeta securely on the floor, hammer in a few nails in random order. They must necessarily protrude 2 cm beyond the edges of the part. After that, fill in the recess with cement, which is prepared for plumbing, and you can drown the wooden part in a liquid solution, nails down. If you do everything right, it will be flush with the floor.

After 12 hours the cement will harden completely.

After that, you can install the device in the prepared place, and for fixing you should use screws, and put cut washers from a rubber sheet under their heads. They are able to protect the bed from splitting when tightening the screw. To make it easier to unscrew the screws, lubricate them with graphite before fixing the toilet bowl.

Helpful hints

The materials for the toilet, despite their strength, are still fragile. For this reason, no force can be used when fastening with bolts or screws.

In order to reduce the pressure under the screw heads, it is imperative to put cushioning pads.

Please note, that when using an adhesive, you should first pay attention to the surface that should be well degreased. If epoxy is used for fastening, then the proportions of the solvent and the base substance should be strictly observed. Cover the surface with adhesive evenly so that there are no bubbles.

In the role of taffeta, you can use multi-layer high-quality plywood instead of wood.

It is important that a good waterproofing is obtained so that the gasket does not collapse over time.


The standard toilet can be fixed to the floor in a variety of ways. We hope that at least one of them will help you solve the problem.
