I didn't have to choose the type of bath for a long time. I was looking for an economical option that would cope with stubborn soil on the site and did not take a lot of time to build.
It turned out that the price for a frame is lower than for a bar, brick or foam block. The winner is obvious - we are building a frame bath. A separate advantage was the ability to build a simple frame with your own hands - without the help of professionals.
The frame bath is light, so you don't have to tinker with the foundation for a long time. I made the foundation of wood (from a bar) and secured it with stakes on the sides. For moist clay soil, this option is optimal. Especially for the washroom, he laid a separate foundation - so that the floor does not cool down in cold seasons and dries quickly.
For laying the floors in a frame bath, I needed 50 * 50 mm bars. I nailed them to the lower part of the log in three rooms - a relaxation room, a steam room, a dressing room. On the bars I laid sub-floor boards, a layer of roofing material and a 10-centimeter layer of mineral wool. On top of the "clean" floor I put glassine for vapor barrier. For the washroom, I picked up a 5 cm round edged board.
Before the construction of the walls, I treated the boards with an antiseptic "Teksturol". The lining was sanded and covered with furniture varnish in 2 layers. For convenience, we carried out the manufacture and fastening of frame walls on the ground, after which we raised them.
As materials, I needed a beam with a section of 100 * 100 mm (for the bottom strapping) and paired boards of 150 * 50 mm (logs for the floor - they fit on the waterproofing of the foundation).
When constructing floor beams and rafters, I used boards 150 * 50mm. He put them on the edge and fastened them together. I used boards 25 cm thick for the lathing. To fasten the trusses, I took special metal plates. Of all the roofing materials, I chose metal tiles. The option is not cheap, but it will last a long time. Outside, the roof was not insulated, since an attic is planned.
For finishing the bath, I used an inexpensive and proven option - siding. First I looked at the blockhouse - it looks very much like a real log house. But for financial reasons he refused. On the outer walls of the building, I placed the lining horizontally, and before that I put a waterproofing layer (glassine) under the upholstery. He laid the whole sheets with an overlap and glued all the edges with adhesive tape. Scotch tape should not be neglected, otherwise excess moisture will accumulate in the bath.
Since we visit the bathhouse all year round, I paid special attention to vapor barrier. He refused roofing material right away for one simple reason - at high temperatures it starts to stink.
A builder friend advised me to take a roll Ursu 50 mm thick.
I put it in vertical posts and at the same time added slats. I intentionally left a 5cm air gap inside the walls.
In the steam room, to create a "thermos effect", I laid the heat insulator with foil inside. For the ceiling, I have provided two materials - foil "Ursu" and a 5-centimeter layer of ordinary insulation. For the decoration of the walls and ceiling, I used grooved linden boards. For ventilation purposes, I prepared an asbestos-cement chimney with a diameter of 12 cmwhich he brought out through the attic.
