When making a bath, it is necessary to take into account a lot of different factors, one of which is water drainage. Errors during construction in this area can lead to the fact that the structure simply cannot be used. Therefore, novice masters very often ask the question of how to properly organize the drain in the bath with their own hands. We provide a step-by-step guide to this process.
Creating a project
First of all, you need to understand that there are just a huge number of options for arranging water drainage in such buildings. Therefore, it is worth first deciding which type should be used in a particular case. When creating a device for draining baths, it is necessary to take into account the features of the building, its foundation and the costs that the builder is willing to pay.
The project should reflect the main elements of the system at the stage of foundation manufacturing, since it will be necessary to make the removal and construction of the floors, indicating the laying of drainage, if their installation is planned. Therefore, if you do the drain in the bath with your own hands, the step-by-step guide recommendsstart designing this element along with the entire building, starting from the very foundation.
In our case, we will consider one of the most interesting options, which requires certain costs, but the quality of the design allows you to never return to this issue. That is why such projects are very popular with modern masters.
Tools
To create a bath drain, you may need the following tools:
- shovels;
- wood saw;
- hammer;
- roulette;
- level;
- paint roller or brush;
- buckets;
- perforator;
- pencil.
Materials
In order to organize the draining of water in the bath, you need to buy the following materials:
- cement;
- sand;
- water;
- roofing felt sheets;
- bituminous waterproofing;
- metal corners made of stainless steel, for fixing floor boards around the perimeter;
- antibacterial primer;
- wooden planks;
- self-tapping screws and impact dowels;
- metal rebar or wire;
- drain pipe;
- film;
- drainage and other fittings;
- damper tape.
Foundation work
It is necessary to start creating a drain even at the stage of making the foundation. The fact is that a sewer pipe should be installed through which the liquid will be drained. Whena do-it-yourself drain is created in the bath, the step-by-step guide recommends installing the drain pipe directly into the base. It is fixed using a damper tape in a concrete foundation or mounted on special clamps when mounted on a pile foundation.
If the pipe is adjacent to the central sewer system, then it is laid underground. At the same time, it should be located at a depth below the freezing level of the soil with additional insulation with mineral wool.
Concrete work
- First of all, a draft floor is created, through which the drain pipe will pass.
- It is stuffed from boards that are fixed around the perimeter of the room.
- A film is laid on their surface so that liquid does not flow out of the solution during concrete work.
- At the next stage, along the perimeter of the walls, at the level where the concrete will be located, a damper tape is installed. It is necessary so that when the screed expands, the surface does not crack and deformation does not occur. Also, the pipe section that will be in concrete should also be wrapped with damper tape.
- Next, metal fittings are laid, which should also be fixed on the walls.
- Then, a bath drain system is made by pouring the first layer of concrete, 5-10 cm thick. This will be the basis on which the liquid guide level will form.
- After the concrete hardens, it is necessary to make another pour with a thickness of 5 cm. However, in this case, the thickness is indicated conditionally. The point is that you need to getflat surface, but create a certain slope for the drain to the pipe.
- Many craftsmen with this filling prefer to make a kind of cone, where the pipe drain funnel will be located in the center.
- Finally, install the drain grate and adjust it to the level of the surface.
Waterproofing
When creating a similar drain under the bath floor, it is very important to protect all elements from moisture. Therefore, the walls and concrete base should be treated with an antibacterial primer.
Further, sheets of roofing material are laid on the floor, leading them to the walls, and the surface is treated with bitumen. It is very important not to forget to cut a hole in the sheets for the drain itself, so as not to close the grate.
As a result, water, falling on such a surface, will flow to the pipe and be discharged through it from the building. Next, you only need to create a final version of the floor, which will be located on a certain hill from the drain.
Installation of floors
Many novice masters, wondering how to make a floor in a bath with a drain, want to use wood, and they want to get rid of concrete surfaces. However, this design will result in a very high quality wooden deck with a concrete base for increased strength and durability.
- Even at the stage of making walls, you need to install logs. They are usually fastened by dovetailing into wooden structures or bricked into concrete or masonry.
- Ifthis was not done during the construction of the walls, then the logs are installed on metal corners, which are fixed around the perimeter. However, it is necessary to create additional supports in the middle of the length of the boards.
- Logs must be treated with an antibacterial primer to protect against moisture and mold fungus.
- The next step is to install the floorboard. It is also pre-treated with a primer.
- A gap of at least 1 cm must be made between the floorboard. It is through it that water will leave, falling on the concrete base and flowing down the drain.
- The board is fixed with self-tapping screws.
- After the floor is installed, experts recommend making special pallets that can be used as a finishing floor. This design allows you to dry the bath after using it.
Drainage
Very often the question of how to make a floor in a bath with a drain also involves the installation of a drainage system. The fact is that the bathhouse is not limited to a shower and a steam room, and it is uneconomical to organize a separate outlet from all rooms.
Therefore, to the room where the central drain is created, a drainage system is made, created from small grooves, which are located near the nearest wall along its entire length. This design is done at the stage of manufacturing the screed, mounting it flush with the floor. Also, it should be borne in mind that the slope of the surface should be towards the installation of the drainage channel so that the liquid flows into it on its own.
Usually like thissystems are created open because they require less materials and labor costs. However, with a thorough approach, you can install pipes in the floor that lead to the central drain, and in order for water to get into them, special gratings are installed at the level with the screed.
Extra work
Experts say that the floor drain is only a small part of the design of the bath, which ensures its proper functioning. It is equally important to install the ventilation and heating of the room correctly so that even with proper water drainage, the room is not damp.
Processing with an antibacterial primer is considered mandatory in our time and requires a special approach to the choice of material. The fact is that it should not emit harmful substances when heated and contain toxic components. It is best to use special products that are designed specifically for the bath. They are completely safe and will help to permanently get rid of mold and fungus in the room, protecting wooden and concrete surfaces from moisture.
If there is no separate sewer system, then creating a drain, you will need to make a cesspool. Experts in such cases are usually advised to make a small septic tank, which is located near the building. This design will quite cope with a small amount of water and will be quite economical and practical. However, such work will require additional investment.
Recommendations from experts
- Given the complexity of the design when installing inbuilding with several rooms, the design stage must be taken very responsibly. It is important to consider the angle of inclination, the length of the drainage, and even the area of the room itself.
- When water is drained from a bathhouse in a structure made of timber or logs, it is recommended that all work be done only after the house shrinks. Otherwise, you may get surfaces with an incorrect slope or different levels of surfaces.
- If a pile-based foundation is used to create a building, then the drain pipe will need to be additionally insulated. It is best to use mineral wool or polyurethane foam for these purposes. However, recently it is possible to purchase liquid insulation on the markets, which has a low cost, and in terms of its technical characteristics is not inferior to other materials of a similar purpose.
- When pouring the main floor from concrete, some masters recommend using expanded clay to insulate the base. It is mixed with a solution and a regular screed is made. The result is not only the necessary foundation, but also a kind of insulation, which is very important in houses with a pile foundation.
- Quite often, instead of bitumen and roofing material, craftsmen use special mastic to create waterproofing. However, before using it, you should make sure that with a slight heating it will not emit substances harmful to human he alth.
- In the building materials markets, you can buy ready-made sewage and water drainage systems. They are practical, reliable and very easy to install. Therefore, sometimes it is worth developing a floor design withgiven their characteristics.
