Waterproofing the walls and floor of a shower in a wooden house: Tips + Videos and Photos Modern wooden houses nowadays provide for the presence of sewerage and water supply systems. The houses are equipped with bathrooms, shower and toilet. The main rule when arranging these structures is the use of high-quality materials and correct processing technologies. Due to the increased moisture in these rooms, the tree undergoes a decay process, becomes covered with fungi and mold, and over time it is necessary to replace the material.

In order to avoid such problems in the future, or at least extend the life of your bathroom, it is necessary to correctly select the finishing materials, to properly waterproof all structural elements.

In this article, we want to tell you in more detail how to make a shower in a wooden house with your own hands.

Constructive elements of the shower

Each owner of his house has the right to independently decide which shower to build, to choose a room, materials and construction technology. However, in order for the shower to work for a long time, we safely recommend that you follow the rules and regulations set out in the SNIP and other documents.

An equipped shower in a wooden house will bring comfort and delight to its owners for many years, if the requirements are met correctly in the following systems and elements of the room:

  • Waterproofing the walls and floor of a shower in a wooden house: Tips + Videos and Photos Sewage ;
  • Waterproofing of walls, ceiling and floor;
  • Lighting and electrical;
  • Competent selection of plumbing;
  • Finishing materials correctly selected for wooden rooms;
  • Shower ventilation.

Tools

The following tools are required to equip the shower:

  • Measuring tools;
  • Spatula and trowel;
  • Containers for stirring grout, mortar and glue;
  • Punch, drill, screwdriver;
  • Hammer and screwdrivers of various sizes;
  • Grinder, hand saw or jigsaw;
  • Wrenches.

Stages of arrangement of the shower room

The supply of the sewerage and water supply system is carried out at the initial stages of building a house. The ventilation system of the house as a whole is also planned and laid. Not only the bathroom, but all living rooms should be well ventilated.

The process of arranging a shower in a wooden house can be divided into the following steps:

  1. Provide the room with a shower with a reliable ventilation system to remove moisture;
  2. Equip drainage outlets of sewage water;
  3. Correctly waterproof all structural elements of the shower room;
  4. Install a shower stall;
  5. Carry out fixing work.

Ventilation system

Everyone knows that wood, by its properties, is capable of releasing oxygen and absorbing moisture.

Therefore, in the construction of wooden houses, a full-fledged ventilation system is generally not provided for in the design. The main thing is to correctly observe the technology of laying the walls and their cladding.If we talk about rooms with high humidity, such as a kitchen, shower or bathroom, then you cannot do without forced outflow of moisture.

The most effective and reliable is the supply and ventilation system. It consists of fans that either draw air into the room or remove excess moisture outside.

It is usually installed under the ceiling.

Tips for ventilation:

  • Waterproofing the walls and floor of a shower in a wooden house: Tips + Videos and Photos Exhaust pipe length must protrude at least 50 cm above the roof level;
  • All parts of the outdoor air duct must be insulated to avoid condensation;
  • Ventilation system equipment must be made of non-flammable materials;
  • Ventilation shafts should be equipped with dampers to prevent the ingress of oxygen in a fire.

The process of room ventilation in the absence of an active ventilation system is carried out due to the temperature difference and pressure drops inside and outside the room. In the cold season, the outside air, getting into the room, heats up, rises and is removed through the hood. In summer, there is no temperature difference as there is no air, so air circulation will mainly depend on the presence and intensity of wind.

Therefore, for shower rooms with year-round high humidity, an exhaust fan must be installed in the ventilation shaft. It will remove excess moisture from the room. And prevent the formation of mildew and mold in the room.

Sewerage

When choosing and arranging sewage pipes, it is necessary to take into account the fact that over time, wooden structures shrink. Therefore, it is better to choose pipelines made of polyethylene, dense plastic or metal-plastic.

The pipes are at a slight slope. Movable joints are used to strengthen them. Pipe diameter 50 mm.

Preparation of the sub-floor

  1. The area of ​​the floor under the shower must be additionally reinforced with supports, which are installed during the construction phase of the house;
  2. The wooden surface of the floor is cleaned of paint, oil stains and dirt;
  3. It is treated with water-repellent and antibacterial substances.
  4. The prepared surface is insulated with polymer mastic or a rubberized membrane is laid.

  5. The drain holes are blocked with ladders;
  6. The screed is carried out with cement-polymer mortar up to 3 mm thick in two standing. Reapplication is possible after 2-3 hours.

After 10 hours, as the top layer dries, finishing materials can be laid on the floor.

Waterproofing and finishing the floor

After the preparation of the subfloor in the shower room, it is waterproofed. Initially, a roll or coating waterproofing material is placed on the rough floor.

Or an ordinary roofing material. Lubricants have an advantage over other waterproofing materials.They can be laid on an uneven surface without additional treatment with a primer or bitumen.

Materials for tightness are laid overlapping the walls. To increase strength and durability, the joints can be additionally reinforced with fiberglass mesh.

The floor level in the shower room is mounted below the level in the rest of the rooms by 2 cm and is necessarily separated by a small threshold. This is to protect the rest of the premises in the event of a water leak. If you plan to install a shower cabin, then it is imperative to make a pallet to the cabin. You don't need to buy it. The walls of the pallet are laid out of bricks or filled with concrete.

Be sure to need a drain for the shower. For its installation, the floor is made at a slight slope. Water goes into the drain on its own.

Next, a sand-cement screed and finishing materials are punctured on the floor. At this stage, it is possible to install a floor heating system.

Ceramic tiles are a suitable material for finishing the shower floor. You can also put it in cork or a special array of thermal boards. Wooden materials are more economical, characterized by great durability, pleasant to the touch, and give the shower a cozy and homely look. But they require additional preparation. It is necessary to carefully treat each board with antiseptic agents that protect the material from rotting, the development of fungus and mold.

Linoleum and laminate are not suitable for shower floors. Linoleum is very slippery when exposed to water. Laminate is not suitable for rooms with high humidity even after treatment with special products.

Moisture protection

All materials can be divided into two categories. The first category creates a protective layer when applied to wood.

The second category is compositions for impregnating wood fibers and giving them the appropriate qualities.

Waterproofing materials that protect wood from moisture:

  • Waterproofing the walls and floor of a shower in a wooden house: Tips + Videos and Photos Roll, sheet materials on a substrate, impregnated with bituminous compounds. Cellulose fiber based.
  • Bituminous coatings.
  • Polymer films, membranes.

  • Polymeric painting and coating compositions.

Impregnation compositions include:

  • Oil impregnations. They can be produced on the basis of natural oil or on a synthetic basis;
  • Varnishes, stains based on polymer resins, organic solvents, fillers;
  • Hydrophobic compounds. When applied, a film is formed on the surface, which repels water, and the surface retains the structure of the wood.

Walls and ceiling: preparation and arrangement

The walls and ceiling in the shower must be prepared and waterproofed in advance.

Roll materials are laid on the surface of the walls and ceiling in two overlap layers. It can be moisture-resistant plasterboard, plastic panels, PVC stretch structure on the ceiling.For waterproofing walls, water panels or ready-made panels of extradited polystyrene are used. All joints are treated with a sealant.

All panels are fixed on timber frames with a gap between the wall and the base for natural ventilation and to prevent condensation from accumulating.

All wooden elements of the lathing are treated with protective equipment.

Shower cabins

If you decide to install a shower cabin in your house with your own hands, you must first choose what kind of cabin will be and from what material.

Cabins are available with or without a pallet. The cab pallet is more practical. It can be made of brick or concrete with tiles.

Showers without a tray with a sloped floor are easier to install.

Glass, a suspended waterproof curtain, or other materials at hand can be used to install the movable wall.

Other materials can be used as the walls of the cabin, such as:

  • Toughened glass;
  • Regular glass with a thickness of 6mm;
  • Acrylic and polycarbonate. Requires framing in an aluminum profile.

Stages of equipping a shower stall:

  1. Waterproofing the walls and floor of a shower in a wooden house: Tips + Videos and Photos We carry out the marking of our cab;
  2. We process the walls with protective equipment.

    , then we apply a water-repellent film;

  3. We close the walls with water-repellent drywall;
  4. Lay the tiles on the drywall;
  5. We rub the joints between the tiles with putty based on silicone;
  6. On we lay out the walls of the pallet made of ceramic bricks or fill it with concrete;
  7. We process the pallet with waterproofing mastic;
  8. Lay tiles with an abrasive coating on the walls and floor;
  9. Install the ladder on the sewer pipe ;
  10. Next, we mount the mixer and a shower head;
  11. On the sides of the structure, we install racks for transparent walls and doors. Or you can replace them with a moisture-repellent curtain.

And the shower is ready for use.
