Inside the hot room, the two-tiered L-shaped bench layout gives bathers more flexibility and comfort. The upper bench provides a hotter, more traditional sauna experience, while the lower bench offers a milder option. The L-shaped design also makes the space feel more social and inviting, ideal for families or groups.

Crafted from Thermowood, this sauna is built for outdoor durability and long-term performance. The heat-treatment process enhances the wood’s natural resistance to moisture, decay, and changing weather conditions, making it an excellent choice for Canadian backyards and outdoor environments.
