I want to share construction experiences indispensable at the cottage. To save material in the same structure combined shower, pre-tribades and through the wall toilet.
Construction works
Toilet pulled a hole with a size of 1000 × 800 mm and a depth of 1200 mm. Boca laid brick on cement mortar, it turns out inexpensive construction. 
Windows and doors
The pre-equipment has only an entrance door, the toilet has an entrance door and two windows of 200 × 300 mm; One serves for ventilation, has a grid and inclined wooden blinds, the second is glazed and serves for lighting. The shower and pre-tribades are separated by a wall with a free passage covering the curtain. In the shower, too, also provided a small window of 200 × 300 mm. Additionally, electric lighting in the closed luminaires has made in the pre-tribades and the toilet.
Facing outside and inside
The pre-tribbon and shower bodied tiles. In the toilet made plaster by "spray". It also plastered the entire outdoor part of the structure. The roof over the shower made reinforced concrete, drowned into it partially tank. The ceiling lined with plastic. Over the pre-tribades and toilet, the roof made a single one: the supporting bars put thin boards, laid the rubberoid in two layers, and then slate.
Water treatments
Revising the ideas of construction, found a lot of suggestions. There were also all sorts of heating with solar energy simply in the tank, and in special heat exchangers with a complex system of inclined tank and connecting tubes, and even biionagrev. Created 
the impression that we live in the absence of electricity and constant sunny days. And what to do, when you are at the cottage in the cold season (March, April, September and October)? After all, at this time we most in the ground or cleaning. And after such work is extremely necessary. Therefore, I went on another path, namely, the electricity water heating took the base. The tank with a capacity of 50 l is heated by TEM 0.75 kW / h for 35-40 minutes. to a temperature of 50 °. How much electricity is necessary for this and its cost? 0.75kW / h2 / 3 h25kop. / KW \u003d 12.5 kopecks.
Get rid of corrosion
But another question during the construction of the soul, unfortunately, is overlooked from the type - the use of a tank made of metal that does not have an anti-corrosion coating. Not only in winter, but in the period of its use in the water there is a rust. Let it be in small quantities, but its presence is felt. I used a 50-liter tank made of stainless steel. Pipes, crane - brass. And the funnel put plastic.
With small dimensions, it turned out a very convenient structure that does not occupy a lot of space and performing its functions. And most importantly - a little material went on it.
Toilet and shower with your own hands
Still on this topic
If you still use the energy of the sun for heating the water, the best of the sun is best to paint the tank with water in black.
Thank you for the article.
Simultaneously in the shower, a drain bowl was made with a pipe from a metal-floating 3/4 "withdrawing it beyond the shower for water drain.
This would like to know more about it.
