In summer, souls are sometimes simply necessary, especially in the country. They often build showers with their own hands, quickly, so it’s the frame that is so popular. It is not difficult to do, its main details are a water tank and a watering can, from which this water is poured onto a swimmer.
The foundation for such a shower is not needed, the frame is sheathed with lining, as in the photo. But you can just cover it with tarpaulin, which is attached with a stapler, and instead of a door make a curtain. It will be even faster and cheaper.
Some effort is perhaps the installation of a water tank on the roof of the structure. If there is no suitable big barrel, then now it is not a problem to buy a plastic container for a shower.
