The sauna room usually has benches on both sides (unless you order U shape benches). It can be presumed that 1 meter of the bench sits one person, in turn, 1 meter of the sauna room sits two people (on both sides). 2-meter sauna would accommodate 4 people, a 3-meter sauna – 6 people and so on. If you plan to lay on the sauna benches, the sauna bench should be about 2 meters long for one person to lay comfortability.
