How to align the floor in the bathroom - one of the questions that occurs often during the comprehensive repair of the house or apartment. After dismantling the old floor, it turns out that the base is uneven.
Regardless of how the floor covering will be laid, alignment should be conducted. The service life of the new coating depends on its quality.
This comment largely refers to the tile. The bathroom is always characterized by increased moisture, which leads to mandatory use in the process of operation of waterproofing compositions.
Where to begin?
Start with dismantling old coating
Technology is quite simple. In practice, you can attract a specialist or following the instructions, perform floor alignment in the bathroom with your own hands.
The latter will require some knowledge, skills and skills.
Initially follows:
- dismantling the old floor;
- Select a new coating;
- determine the degree of curvature of the draft base (tie);
- Calculate the thickness of the leveling layer, which will allow you to purchase an aligning material in the desired quantity;
- Conduct waterproofing.
Clean the floor from the construction trash
The old coating is removed by a perforator, hammer, lomik to a screed.
If it is crumpled or snapped with cracks, it is better to get to the concrete overlap.
It should remove the discontinued parts and the bugberry areas (align at the maximum). After removing the garbage.
Additionally, it is possible to treat the purified surface with concrete contact (primer material). This will strengthen the adhesion of the base with the leveling layer.
Tile - Ideal for floor bathroom
The most common options for flooring include: tile, laminate (with elevated moisture-resistant characteristics), linoleum, bulk polymer compositions. It is possible to use wood previously treated with special means.
A large selection of them (from different manufacturers) is provided by construction shops. Each of the proposed materials gives the bathroom unique view.

The use of a regular level will show all irregularities. To calculate the future height of the altitude, it is necessary to determine the highest point of the base and add a minimum of 3 cm at least (the height of the lighthouse is taken into account).
The floor in the bathroom is aligned in the same way as in other rooms, but taking into account waterproofing.
What materials apply?
After pre-training, the alignment stage begins. In this case, it is possible to use multiple species (separation by properties): bulk (self-leveling) and leveling. Their large selection gives construction supermarkets. They are sold in moisture protected bags.
Bulk formulations spread across the floor, filling all cracks and irregularities, forming a smooth surface
For practical application, bulk formulations that are significantly simplifying work. They themselves fill the cracks, spreading evenly on the floor. Produced for draft and finishing finish.
The first option is used to create an aligned base (with minor irregularities), which after the finishing solution is adjusted.
According to the beacons, the leveling solution is racing. The basis of it is cement.
On each package with the material, the preparation instruction is given according to which the contents of the bag falls into the container proportionally filled with water.
Everything is mixed with manually or a mixer before obtaining the desired consistency.
If after opening the bag it turns out that the material of improper quality (hardened, wet), then it is impossible to use it.
The simplest and cheap way to create a screed is the use of a mixture of cement with sand, but this option is distinguished by high labor costs.
Waterproofing screed
Waterproofing, treat the floor with a wall
Waterproofing starts working on alignment.
For this, rolled, penetrating, coating waterproofing compositions are used.
Not only the floor is processed, but also the walls at an altitude of up to 15 cm from it. Typically, treatment occurs in two layers.
Leveling clay
Keramzite can align the base without a significant increase in the load on the supports

With significant base irregularities (the slope of the plane is more than 3 cm), clamzite is used to create a layer of screed. This option, almost without increasing the load on the overlap, allows you to raise the surface level.
But the method is infrequently used, because significant differences in height are rare in the bathrooms. Stages of floor alignment process in a bathroom with clay:
- in terms of installing guides;
- The gap between them is fill in the clamzite (3 cm below the top of the lighthouses);
- You can put the reinforcing floor the grid, to be treated with a clutch solution;
- pour the cooked solution, to dissolve the rule;
- Cover the film, periodically wateted with water, wait for drying (up to 3 days). For details on how to make a screed on the clay, see this video:
The use of self-leveling mixtures
When in the bathroom height oscillations in relation to the base no more than 3 cm, then it is advisable to use bulk mixtures.
This rule acts both when aligning sex in the bathroom and by other rooms. Preferences when choosing is given to mixtures with a high level of moisture resistance.
The process is as follows:
- The contour of the room is lit down;
- The solution is prepared in accordance with the instructions in the liquid form;
- It is evenly poured on the floor (for rapid spreading, the spatula is produced);
- If the room is large, it is better to work in a pair;
- Air bubbles formed during the pouring are removed by a needle roller;
- It is possible to walk on a solution only in special shoes;
- Drying time up to 7 days. For more information on the use of these mixtures, see this video:
Leveling process for lighthouses
Use metal profile for montage
Lighthouses are used for the use of cement solutions.
It is often equal to the floor in the bathroom under the tile. P-shaped and T-shaped types of lighthouses received the greatest distribution.
The process of installing beacons and fill the screed looks as follows:
- There is a zero level (using construction, water, laser levels);
- It is transferred 3 cm up;
- All beacons are exhibited on it, which are attached to the solution (quickly freezes);
- For the preparation of the solution, you can purchase ready-made mixtures, to mix the cement with sand (1: 3);
- water to add to the mixture until the desired consistency will be obtained;
- The prepared composition pour out between the beacons and to dissolve the rule;
- After filling, cover the screed and saving water from time to time;
- Additional waterproofing and installation of the coating - when completely dry.

The methods listed above can align the floor in the bathroom under the tile or any other coating.
Phased all work can be submitted to the table.
| Stage | Work performed | Used tools, materials |
|---|---|---|
| preparation | Removal of old coating to a solid base, garbage cleaning, waterproofing | Perforator, scrap, sledgehammer, hammer, vacuum cleaner (broom); Waterproofing compositions |
| Alignment | Installation of screed selected way | Mixer, concrete mixer, rule, rollers with nozzles, spatula, construction level; Bulk or cement formulations, clay |
| Drying tie | Maintaining the required temperature, humidity | heat gun, heater; polyethylene film |
| Laying coating | Installation of the selected flooring | Tools are determined by the type of material and the installation method; tile, boards, laminate, linoleum |
A high-quality screed using the above methods is obtained by some conditions:
- The air temperature of the room is 5-25 degrees;
- Moisturity - less than 90%;
- During the work there should be no drafts.
