When designing and building wooden houses, special attention should be paid to the finishing of "wet" rooms. These include bathrooms, sanitary facilities, kitchens. It is necessary to take into account the maximum permissible values ​​of moisture that adversely affect wood. Moisture creates good conditions for the development of fungus and mold. Therefore, the bathroom in a wooden house is being equipped in accordance with all the rules and technologies that allow creating a reliable waterproofing of the premises.

Features of wooden houses

The material for the construction of wooden houses is cylindered logs and profiled timber. In connection with the change in the form of wood under the influence of moisture, the arrangement of “wet” rooms should be carried out strictly according to technology. Particular attention should be paid to the device waterproofing, sewage and ventilation.

Wood surfaces should be treated with antiseptic and protective agents, linseed oil or linseed oil.

Shrinkage of houses occurs during operation, and wooden buildings are no exception. During shrinkage, the joints are depressurized and the walls and walls are deformed. Therefore, a separate supporting frame is necessary for the bathroom, and for pipe material it is better to use plastic and metal-plastic. For fasteners such pipes fit special clamps with rubber gaskets.

Metal-plastic pipes are the best option for running water in a wooden house

Preparatory work begins with the design

When calculating load bearing capacity of walls and floors must take into account the load that will create the furniture in the room. For bathrooms, sanitary facilities it is necessary to take into account the varying weight load. For example, it is necessary to take into account the weight of water and a person bathing in it.

Therefore, reinforced ceilings are designed for bathrooms so that the sanitary room is reliable and durable. Beams at this place use a thicker section, the distance between them is smaller, and the thickness of the overlap is made at least 25% larger.

The floor in the bathroom in a wooden house must have a cement screed, therefore, when designing the beam, it is lowered to the distance of the future screed. Usually it is about 20 cm. If you miss this point, the floor will be higher than the floor level of the other rooms, you see, it will not be very convenient.


It should be remembered: the bathroom in a wooden house should be equipped with a ventilation system that is as important as the sewer and plumbing. If you do not remove moisture from the room, the tree can be exposed to mold, fungus, deform and collapse.

Special attention should be paid in the house made of ventilation wood - this will help prevent the formation of mold on the walls

To remove moist air from the bathroom rooms use forced ventilation. To do this, the installation is mounted in the attic, taking into account all safety requirements:

  • the installation of the ventilation units is carried out on stands to prevent contact with wooden beams or the floor;

  • materials should have an elastic structure and fire-proof properties;

  • ventilation ducts through interfloor overlappings are laid through compensation holes;

  • fans, installed directly in the premises themselves, are made of moisture-resistant materials.

Basics of waterproofing

Since wooden structures are afraid of moisture, the bathroom must be waterproofed, so that steam and moisture can not get outside the bathroom.

All waterproofing work must be carried out according to all rules and regulations. Before starting work, preparatory activities are carried out: the surfaces of the walls, the ceiling, and the floor must be cleaned and leveled.

Approximate floor waterproofing scheme

Floor and ceiling waterproofing is carried out simultaneously. Polymeric self-leveling floors, water glass and roofing felt are recognized as the best among waterproofing materials.

The easiest to install and therefore roll materials and moisture barrier blends are popular. The mixtures are applied to the treated surface and, after drying, turn into a waterproof, durable film. In turn, the rolled material is already initially a durable moisture-proof layer. Installation of roll waterproofing overlap to prevent moisture from entering through the seams between the rows of material.Finishing the bathroom in a wooden house begins after waterproofing works on all surfaces of the room.

Floor waterproofing

Two types of materials are used for waterproofing the floor:

  • roll, on a bitumen basis;

  • coating compositions.

The rolled ones will have to be purchased slightly more than the area of ​​the premises being processed, since this material is laid with overlapping strips of at least 12 cm in length with spikes on the walls of about 20 cm. Still need bitumen glue to lubricate the joints of the bands and places overlaps.

When choosing a roll-up waterproofing, you must take into account the overlap of the sheets, which must be smeared with special glue

The resulting flooring is again smeared with bitumen glue it fits the second row of material, but with a shift. The shift is done in such a way that in the middle of the upper band to cover the joints of the strips of the first row. If necessary, you can lay the third row of waterproofing material.

The coating compound is applied with a spatula or a wide brush. Depending on the type of coating waterproofing, there are certain nuances in the application:

  • Bituminous mastic. Concrete work surface requires hot-applied waterproofing and specialized equipment. All other surfaces are treated with cold application.

  • Bitumen-polymer blend. Introduced plasticizers and latex fillers only improved the composition of the bituminous mixture. The resulting waterproofing does not shrink, does not crack, retains its elasticity for many years.

  • Acrylic blend. The most optimal use of the inside of the house, as it does not emit an unpleasant smell. Other positive characteristics can be distinguished strength, plasticity and ease of application.

Mastic should be applied on the prepared surface of the floor; further work begins only after it is completely dry.

Waterproofing walls

Walls in a bathroom in a wooden house, they are isolated in one of three ways:

  • Plastic films. The required amount of material is measured, after which it is evenly attached to the surface with staples;

  • Water-repellent solutions. If it is important to preserve the original appearance of the wood from which the walls are made, then the use of these solutions is the best option;

Good water-repellent materials will help preserve for a long time the natural nature of wood

  • Plastic panels. The most simple and cost effective option. Of course, the design of the bathroom will not be different creativity and originality, but due to this, you can reduce the time and cost of repairs.

Installation of sewage and plumbing systems

An important issue in the decoration of sanitary rooms is the installation of a sewage system and plumbing. After all, even a small leak of these systems can ruin everything.

Before installation, the load on the floors is carefully calculated, the water consumption is planned, the volume of the septic tank or sewer is calculated.

When installing, provide compensation gaps. At the base of the foundation, a reinforced concrete chute is constructed around the sewer outlet, this is done to prevent sewer pipes from shifting.

Plumbing should be protected from sub-zero temperatures, so that the bottlenecks are insulated with special insulating materials.

In order for the plumbing pipes to not be frosty, they should be well insulated.

Examples of finishing of sanitary rooms

B the construction process will sooner or later have to decide how to sheathe the bathroom in a wooden house. To do this, use a variety of solutions, both classical styles and extravagant. It all depends on the financial condition of the owner, his desires and fantasies.

Whichever style is chosen, you should follow certain rules:

  • when choosing a material, you should pay attention not only to the appearance and attractiveness, but also to the possibilities of the material itself . Examine what detergents can be used, how to wash and care for the coating;

  • the best option when choosing a material is ceramic tile, it can cover both walls and ceiling;

  • more spacious rooms can be decorated with marble, artistic mosaics, and even wood, pre-treated with a moisture-resistant varnish; and steam, sound insulation properties, reflective ability and availability e discharge of harmful substances from the material.Most often used for finishing suspended ceilings.

The suspended ceiling is most often used for finishing rooms

  • for optimal flooring the option is ceramic tile. Its surface can be both rough and smooth, but always with anti-slip properties.

Types of bathroom lighting

The lighting in the bathroom can be divided into general and point. The general lights the whole room; for this purpose, one lighting fixture is installed on the ceiling. Point lighting emit zones of the sink and mirrors.

Of the lighting fixtures for bathrooms, it is best to use low-voltage fixtures, such as halogen lights. Their operating voltage does not exceed 12 V. Wiring is carefully isolated from moisture.

Conclusion - the choice of plumbing devices

The most pleasant stage of repair work, signaling their completion, is the choice of plumbing devices. Restrictions on the choice of sanitary equipment are practically absent. The main thing to consider is the weight of the installed equipment, taking into account the calculated loads on the floor of the house. The main elements of sanitary equipment are a washbasin, a bath (shower), toilet.
