• Pre-cut wall and ceiling boards.
• Three interior wood options.
• Configurable matching benches.
• All-glass door and sauna accessories.

The kit includes an all-glass door, not a full glass wall. Backrests are supplied flat; angled installation may require on-site spacers. Wall boards normally run horizontally; room widths greater than eight feet may require an interior joining seam. Follow manufacturer safety and clearance guidelines.

Heater selection must account for finished room dimensions, construction, ventilation and manufacturer installation requirements. Electrical work and heater installation must follow the heater manufacturer’s instructions and applicable electrical and building requirements.
