The main advantages of a wooden beam
The only savings of the beam is that you cannot make it yourself, but you will have to purchase ready -made and processed material, and the chopped forest will have to be additionally processed manually to remove the bark.
Another advantage of the beam is that during the factory manufacture, its processing is immediately processed using special antiseptic agents, so you do not need to carry out additional work after the construction of the bath. If you still decide to build a bath yourself, then you should treat this case with special responsibility and get acquainted with some tips.
