ThermaSauna 4M with a relax room is a perfect barrel shaped outdoor sauna for spacious homestead or a small yard which is ready to use first day after delivery. The sauna has 2 benches (200x58 cm) inside the sauna, which allows 2 persons laying down or 4-6 persons sitting in the sauna. Also, it has a relaxation room with benches, where you can change your clothes, have some relax, cool down between sauna sessions and enjoy your time with your family and friends.
 
Sauna does not require heavy foundation. It can be placed almost anywhere temporary, but for a permanent installation we recommend to put it on terrace, paving, stone chips or at least few bricks under corners. Construction is strong and very stable, which makes it safe to lift the whole sauna (i.e. for transportation, to change location in your garden, to sell it in future etc).
