Bathroom in a wooden house: the rules of arrangement and finishing features

Waterproofing wooden floors, walls and ceilings in the bathroom

A bathroom in a wooden house requires increased attention to waterproofing, providing protection from water to the ceiling, floor and walls at the same time. • Waterproofing of the bathroom floor is carried out according to generally accepted rules

Several layers of waterproofing roll materials are laid on a concrete screed, which are covered with a solution of cement and sand from above. After that, a warm or regular floor is mounted. Insulation from excess moisture will be more reliable if the film covers the bottom of 10-20 cm of walls along the perimeter

• Waterproofing of the bathroom floor is carried out according to generally accepted rules.Several layers of waterproofing roll materials are laid on a concrete screed, which are covered with a solution of cement and sand from above. After that, a warm or regular floor is mounted. Insulation from excess moisture will be more reliable if the film closes 10-20 cm of the perimeter walls from below.

A variant of the floor covering in the bathroom can serve as a glue cork, opened with varnish, moisture-resistant laminate, linoleum or ceramic tiles with an anti-slip effect. They are easy to clean, not affected by steam and moisture, have an attractive appearance and affordable cost. An alternative option would be natural marble or artistic mosaics, which would be more appropriate in spacious bathrooms with matching furnishings.

• Walls can be waterproofed using finishing materials - ceramic tiles, plastic panels, mosaics, etc. All of them are quite resistant to aggressive elements of detergents and are easy to clean.

A good water-repellent result is obtained by pre-impregnation of wood with special antiseptic compounds that protect it from unwanted microorganisms and insects. So if you do not want to clad the bathroom in a wooden house with non-natural materials, take care to give the timber a sufficient level of waterproofing. It will be easier to do this if you take yew or larch as the starting material - the most durable types of wood in our area. Wood has a low thermal conductivity, so the heat inside the bathroom will be long-lasting even without additional interior cladding.

• The ceiling in the bathroom should not only be waterproof, but also have a sufficient reflective effect. You can make it hanging or stretch. Ventilation grilles and spotlights are easily combined with suspended panels, chandeliers and large lamps will look advantageous against the glossy background of the stretch fabric.

Wall, floor and ceiling decoration

After the reliable waterproofing is ready and completely dry, the turn of finishing works comes. When choosing materials, you should take into account the features of the room, which is located in a wooden house.

What floor to make in the bathroom?

The basis for finishing the floor will be a concrete screed, poured over the waterproofing layer. It should have a slight slope, thanks to which an emergency drain is equipped in the floor.

For finishing the floor most often used:

• laminate;
• porcelain stoneware/ceramic tiles;
• linoleum;
• moisture resistant wood.

An elementary and far from the worst cladding option is ceramic tile. The wooden floor looks beautiful and organic in the bathroom. If you want to save money, you can get by with linoleum.

The laying of hard types of coatings on the floor in wooden houses is carried out according to a floating pattern. That is, they are not fixed rigidly to the base and between the walls of the building and the screed, together with the tiles laid on it, for example, leave a gap of 1.5 - 2 cm.

Room waterproofing

Waterproofing is at the core of a bathroom renovation, whether or not additional wall cladding materials are used. The bathroom should limit the humidity zone to its territory. Wooden walls, the ceiling should be treated with special solutions against moisture, fungus and mold.In order to equip the waterproofing, two layers of film should be used, which must be distributed evenly over the entire floor area with a transition to the walls at least with a rise of 20 cm

When installing heavy plumbing units, it is important to strengthen the load-bearing elements of the floor structure. They must withstand a load of at least 460 kg/m2

In the early stages of construction and repair, such work can be done by hand. To do this, it is necessary to reduce the distance between the beams, while increasing their cross section. The floor level of the bathroom must be made 20-25 cm lower than the floor covering of the rest of the rooms. After the floor is arranged in the final version, the level will rise just to this height.

A bathroom in a wooden house requires an integrated approach. In order to equip it, you need to carefully perform the necessary work at several important stages.

1. Install an effective ventilation system.
2. Establish a reliable sewerage and drainage system.
3. Make high-quality waterproofing with your own hands.
4. Install plumbing.
5. Sheathe the walls with finishing materials.

The arrangement of drainage is of paramount importance, since a wooden building gives a noticeable shrinkage

It is important to use materials that are resistant to deformation. Modern technologies make it easy to solve such problems even when building a house with your own hands.

The plastic pipeline should be fixed with clips, between which rubber gaskets must be installed. In addition, special insulating materials will help protect the sewer from frost. The interior, design of the bathroom must be thought out in advance and the sanitary unit should be equipped in the most efficient way.

According to the advice of experts, the base of the floor covering should be a concrete screed. This will allow you to choose different flooring options: from tiles to warm floors on a wooden base. The flooring design can be chosen by the homeowner based on this solid foundation.

Wood has a porous structure that absorbs moisture like a sponge. How to make high-quality repairs, sheathe the walls, the ceiling with your own hands in the bathroom is most effectively worth thinking about in advance. The first thing to do is do-it-yourself high-quality waterproofing of walls, ceiling, floor. There are two ways to do this.

Coating method, which is characterized by the use of materials with excellent adhesion to all surfaces. They are easy to apply by hand. They are of different types:

• Bitumen-polymer, creating a durable insulating layer due to latex fillers. They are applied to the surface without preheating. Bitumen components securely hold the composition on the surface of the walls.
• Bituminous waterproofing can be cold and hot according to the method of application. The cold method is not suitable for concrete substrates.
• Acrylic waterproofing, which is by far the most environmentally friendly and modern. It is durable and plastic. Such a composition will protect any shower cabin.

Pasting materials roofing felt and roofing material have long been used in construction. Waterproofing procedures with their help are quite laborious, since they require preliminary surface preparation. In addition, old technologies involve the use of a gas burner.There are, however, more modern options. These are self-adhesive materials that are attached to the surface of walls, floors, ceilings after removing the protective film.

Ceiling and walls - choose the material

Finishing surfaces that fit into the interior of a bathroom in a wooden house are various models of panels and drywall. In terms of their qualities, they are not inferior to other materials, but they look beautiful and are much cheaper than tiles or stretch fabrics.

Lighting for the ceiling of the bathroom consists of several lamps connected to each other. They are mounted in a canvas attached to the base, and help to evenly distribute the light rays inside the room.

If the room is large, you can hang a chandelier in the central part and hang several sconces (small lamps) separately in places where light does not penetrate. This design will give the bathroom comfort, warmth and an atmosphere of mystery.

Dark wood combined with white in the interior of the bathroom looks very beautiful.

Wooden bathroom design with shower

For wall decoration, in addition to high-quality waterproofing, wood materials are suitable. They fit perfectly into the design of the room and create a unified style. In addition to wooden panels, tiles are also widely used. It is a versatile finishing material and has long occupied a leading position among bathroom coatings. The main qualities and advantages when using tiles are:

• durability;
• practicality;
• big choice;
• ease of use and care.

The need for ventilation in a frame house

Mold may appear in a frame house due to high humidity, so ventilation is necessary

The walls of buildings from the frame are able to retain heat well indoors and thereby reduce energy costs. This effect can be achieved through the layer-by-layer laying of insulation, the use of materials with vapor barrier, interior and exterior trim details. The efficiency of this type has its drawbacks, it provokes an increase in the level of humidity in the room, as well as incomplete removal of exhaust air from there.

The protective layer of the vapor barrier is able to retain the condensate remaining inside the walls, accumulating it can ruin the insulation, finish and frame, which begin to rot. A ventilation system in this type of house is also necessary to prevent the accumulation of vapors of chemicals that treat frame bars, strapping and other elements inside the premises. They are impregnated with special antiseptics from rodents and insects.

Ventilation in a Finnish house

Insulation between walls without ventilation begins to accumulate condensate

When building according to Finnish technology, insulation up to 100 mm thick is laid inside the wooden frame. After that, the frame is sheathed with timber from the outside and inside. This technology is not widespread enough in Russia due to the lack of the necessary protective materials for hydro- and vapor barrier. Ventilation in a Finnish house must be well organized, otherwise condensate will begin to accumulate inside the walls, which will render them unusable. Without protection from moisture, seals quickly become overgrown with fungi and mold. The presence of even the simplest ventilation system helps to improve the microclimate inside a Finnish frame house.

The procedure for arranging a bathroom in a wooden building

When asked how to make a bathroom in a wooden house, qualified craftsmen give specific recommendations. Following these practical tips, you can competently and quickly equip such a bathroom, thereby extending its life and the convenience of staying in it.

Often, in addition to the main bathroom, additional guest latrines are equipped in the house. When designing them, it is necessary to pre-mark the points of installation of equipment. It is better not to design a bathroom next to a toilet and a kitchen; it would be more appropriate to arrange a restroom next to the bedroom or between two adjoining rooms.

You will receive a completed interior only if you draw up a preliminary project and think through all the nuances

Before purchasing building materials, plumbing and related products, it is necessary to carry out the following preliminary work:

• measure the dimensions of the room;
• choose material for sewer pipes;
• establish the future location of valves, water pipes, sewers and ventilation systems;
• plan wiring and lighting installation;
• determine the indentation of plumbing from the walls;
• conditionally place plumbing fixtures.

As a rule, the bath is mounted in such a way that its long side is located close to the partition. If the dimensions of the room allow, you can place it in the center. Then it is better to lay communications to the bath under a specially made podium. Near the bath, it is recommended to free up a space of 700–1000 mm in size in order to make the approach to it as convenient as possible.

Hooks, hangers and heated towel rails are recommended to be placed at a distance of no more than 700 mm from the bath or shower.

It is recommended to install the toilet in such a way that there is at least 600 mm of free space in front of it.

The sink is usually hung about 800 mm from the floor tiles. But it is worth considering the growth of your household, so that everyone can use the washbasin comfortably.

It is necessary to take into account the degree of hydrophobicity of finishing materials

Finishing a bathroom in a wooden house, a photo of samples of which can be seen in the gallery of this article, should be carried out using materials that do not allow moisture to pass through. It is recommended to finish the floor with tiles, before laying a layer of waterproofing.

When planning the placement of lighting fixtures in the bathroom, it is worth considering the installation of additional spotlights, in addition to the main light source. As a rule, one luminaire mounted on the ceiling is used for the main lighting. Local lighting is mounted in close proximity to the washbasin and mirrors.

rustic bathroom design

“The ideal solution for furnishing a bathroom in an ordinary wooden house would be oak furniture”

The final decoration of such a room should begin only after you decide what you want to see as a result of such work: an exotic bathroom in a real rustic spirit or an interior that practically does not differ from the city. With a modern design, there will be no special questions. Choose your style, purchase materials and get to work, but trying to preserve the primitive atmosphere is much more difficult.To give the bathroom the charm of simplicity, it can be furnished with wooden furniture and decorated with rustic-specific accessories. Just when choosing such furniture, keep in mind that the standard made options will not work, so look for items that are protected from moisture damage by processing. If you have not found anything suitable on your own, cover the furniture surfaces with enamel, varnish or go over them with a primer.

wood wall cladding in bathroom

The ideal solution for furnishing a bathroom in an ordinary wooden house would be oak furniture. Wood of this kind is quite strong initially and furniture made of it can stay in a specific bathroom environment for quite a long period without any additional protective and protective treatments.

Before filling the interior of your unusual bathroom with accessories, consider how you will use them. All items that appeared in the environment should not stand idle. For example, wicker baskets can be used to collect dirty linen or clean linen. On the shelf you can put towels, etc.

In general, the bathroom space, especially in a wooden house, will never turn out to be comfortable and cozy if you do not follow certain rules in its organization. So what do the experts recommend?

combined wall decoration: the lower part is sheathed with a metal profiled sheet, the upper part with wood

1. When choosing an interior color palette, do not choose too dark shades and do not go in cycles in overly flashy colors.
2. The bathroom is the only room where the ceiling can become a continuation of the walls in color scheme.
3. Be sure to waterproof the room.
4. Do not finish the walls clean without first treating them with waterproof mixtures.

What else is valued for wood in the interior is for its unconditional environmental safety. With just a little effort, a rustic bathroom with the natural beauty of real wood preserved will be the highlight of your home.

Materials and tools

For covering the bathroom, you can use both drywall and DSP boards. They are less vulnerable to moisture and are suitable for walls, floors, ceilings.

Any size door will fit. Usually use panel boards covered with plastic or veneer

It is important that the coating protects them from changes in temperature and humidity levels. The ends of the door leaf from below and from above must also be protected from moisture.

Suitable glass (frosted) doors in a metal or wooden frame using seals.

Sheathing frames are made of galvanized metal profiles. They are easy to use: frames of them are quickly erected, they allow you to hide communications, install installations. The result is perfect surfaces that are suitable for any finish. The partition space between the sheet materials is filled with noise-absorbing materials. Sound insulation is higher than that of a brick wall. On such a wall you can install a cabinet, a mirror. But to install a water heater, you need to mount additional metal holders into the wall.

For the floor, a laminate is suitable, which has good reviews.

To perform all work with proper quality, you need to acquire a set of necessary tools: a circular saw; hacksaw for metal; wrenches and pipe wrenches; lerka with dies; vise; plunger-pumping; calipers; screwdrivers with a flat sting. You will also need a pipe bender, clamp, locksmith tools and a few fixtures.

Connecting pipes with threads is better than welding, because this method allows dismantling if necessary. A vise and a wrench with dies will help to cut the thread.

For assembly and disassembly of pipe joints, wrenches 14x22, 19x22, 17x19 and cap heads are required. You need an adjustable wrench and pipe lever wrench.

Tiled walls and waterproofing

With the complete finishing of the bathroom in a wooden house with tiles, you will have to additionally build false walls around the entire perimeter. The design is not new and is used when leveling walls with drywall in brick houses and city apartments. There is only one difference - the use of a sliding fastening of the frame (battens) to the main walls and partitions. This method is necessary so that the shrinkage of the wooden walls of the house does not have a destructive effect on the interior tiling.

The principle of operation of the sliding fastener

The technology is well-established for both wooden beam battens and a metal profile frame for drywall installation - there is even appropriate fasteners produced specifically for such purposes.

If you do not tile all the walls of the bathroom, then the most difficult part is the bath, shower and washbasin area. In this case, a combined wall decoration is used, which can be on the same level when tiles and wood paneling are attached to a common frame.But it can also be on two levels, when the inner surface of walls and partitions does not need decorative finishing - for example, in houses made of logs or glued beams.

This part of the waterproofing of a bathroom in a wooden house can have different schemes.

With full wall cladding with moisture-resistant drywall, coating waterproofing can be performed over the entire surface, or only in the bath, shower and washbasin areas.

With a combined finish, such work is needed only in the indicated areas.

The choice of mixtures for creating a waterproofing layer is quite wide

But even in the case of complete waterproofing of the floor and walls, ceiling in a wooden house remains unprotected from high humidity. And the use of suspended structures or a stretch ceiling only worsens the operating conditions of a wooden floor - without good forced ventilation, warm air saturated with water vapor will moisten it.

2 How best to create a floor base - modern technology

The first thing to consider when designing a subfloor in a bathroom is the load on the load-bearing beams. It is necessary to decide in advance where bulky plumbing fixtures will be installed, and add additional stiffeners in these areas. When calculating the expected load on wooden floor beams, not only the own weight of the bath, for example, but also the water filling it, is taken into account.

The second important point that you need to worry about before starting the installation of the floor in the bathroom in a wooden house is the correct laying of sewer and water communications.It takes into account the fact that wooden houses, even built from modern high-quality lumber, shrink significantly. Therefore, the priority is elastic pipes (metal-plastic and cross-linked polyethylene) and their rather mobile fixation to building structures during the installation of communications (special clips are used to allow the pipes to move).

Now about the floors themselves. It is possible to create a base for laying tiles not only with the help of cement-containing solutions (concrete, cement-sand mixtures, packaged levelers). Now for these purposes, including in wet rooms, durable moisture-resistant plates are successfully used. These include some varieties of plywood (FSB, FOF) and OSB boards. Flooring from these materials, produced on bearing bars, creates a durable, even and resistant to moisture surface suitable for laying ceramic floor tiles.

Mounting plates can be sewn over wooden floor beams if they are level, but logs are usually mounted perpendicular to the main bearing bars. This is done to align the floor surface of the bathroom with the floors of adjacent rooms. As a log, you can use bars made of ordinary wood, pre-treated with antiseptic impregnations and waterproofing materials, but it is better to use glued timber that is resistant to deformation, has increased strength and a smooth surface. When installing the log, the thickness of the sheathing slabs and the tile adhesive plus tile (porcelain stoneware) complex are taken into account in order to reach the level with other floors in the house without the formation of thresholds.

If moisture-resistant plywood is used and the tiles are laid correctly, additional waterproofing is not required.

In addition to the main longitudinal lags, before sheathing them with plates, transverse bars are installed at a level with the main ones. These structural elements are needed for joining fragments of OSB or plywood, and also as a basis for fixing plumbing fixtures. The slabs that form the base of the floor are attracted to the bearing bars with self-tapping screws in increments of about 15 cm. The seams between the fragments of the slabs are sealed with silicone or liquid glass. Such a base (when using moisture-resistant varieties of plywood and OSB) does not require additional waterproofing. Properly laid floor tiles with sealing joints with moisture-resistant tile grout in itself create a reliable moisture barrier.

Concrete base device

The classic pouring technology for making a screed is as follows. A layer of thermal insulation is laid, on it is a reinforced mesh or a lattice of steel reinforcement. In the case when the installation of a water floor heating system is provided, its pipes are fixed to the cells of the reinforcing cage, and then concrete of a high strength grade is poured.

The best basis for floor tiles will be a cement screed

Of course, beacons must be installed before this. After the walls are plastered, ceramic tiles are laid on the floor surface.

A bathroom in a wooden house, equipped with a concrete screed, made in compliance with this technology, will function for a long time and reliably.

5 The wall as a canvas for creativity

When the owner begins to finish the walls in the bathroom of a wooden house, he needs to be extremely careful.Due to its structure, wood is exposed to high temperatures and humidity. She dries out with age.

The easiest option is to make wall cladding. To do this, metal frames are installed at a distance of 1-2 cm from the wall, on which plasterboard sheets or plastic are then placed. If the owner decides to use drywall in the bathroom, he will have to take a number of measures to protect it. To begin with, the frames need to be sheathed with polyethylene. The sheets themselves are treated with a special waterproof paint.

If you don’t want problems in the near future, the owner should put a crate, on which then place a false wall for other finishing work. Its use is not required only if it is planned to install wooden rails.

An independent structure for subsequent procedures is erected on a special sliding metal profile frame. It is installed on the wall using movable joints in the form of vertical grooves with screws inserted into them - in case of damage to the main surface, they set in motion, and the cladding remains the same as it was. It is worth remembering that when erecting false walls, you need to leave room for the ventilation system.

An excellent option for bathroom design will be a combined method. It lies in the fact that wood lining is laid on the base. And on those areas that are most susceptible to interaction with moisture (bathtubs, sinks, jacuzzis, showers), tiles are usually laid.

In addition to moisture and temperatures, there is another danger for the bathroom - household chemicals. Its composition is aggressive for the environment, especially for delicate natural materials.Therefore, it is necessary to secure risk areas with ceramics, wall paneling or porcelain tiles. The main surface can not be touched, unless treated with impregnation from water and mold.
