SaunaLife Cube Construction
The structures of the SaunaLife luxury cube are made out of Nordic Thermo-Spruce. Spruce is the most common sauna wood in Finland. Spruce can last 2x as long as cedar when exposed to harsh outdoor environments combined with changing sauna temperatures.
As for the interior, it features ergonomic benches and backrests. The seating and backrest have been slightly curved to support better posture and make the sauna more comfortable to sit in. Thermo-Aspen is used in the benches because it stays cool in a hot sauna environment and is the most comfortable wood to sit in. Thermo means the wood has gone through a thermal modification process that makes it withstand the high temperatures better so it won’t color or warp as easily as regular wood might.
