Standard air dried T&G boards used for sauna construction will likely shrink and warp after many sauna sessions. Stainless steel nails are best to use in sauna construction to eliminate chance of fasteners corroding and leaving unsightly streaks on walls and benches.
Sauna benches are important to properly plan for your sauna construction project. Comfort, function and best utilization of space should be considered. If the sauna room is wide or long enough to lay down, 24" deep benches are most comfortable, otherwise 18" benches work well for sitting. Standard bench heights are 18" and 36" from floor for 2 tier benches. If you have at least a 7' 6" ceiling height, you can have a 3rd tier bench at 54" height. Remember more bench area in the upper tiers is best for the high heat zone. A general rule might be you lose 1 degree Fahrenheit for every inch from ceiling so you don't want excessive space above your head when sitting on top tier bench.
