Complete Building Kit — Sauna Optimal Alder | Full Turnkey Sauna Kit
SAUNA OPTIMAL is a well-thought-out building kit combining natural alder, modern LED lighting and reliable Harvia equipment. Created for those who appreciate the cosiness and aesthetics of natural wood, soft light and the comfort of a Finnish sauna.
Premium alder is resistant to moisture and temperature changes, does not emit resin and retains its shape even with regular heating. The kit includes everything needed for the self-construction of a medium-sized sauna — from the frame and lining to thermal insulation, lighting and the Harvia Wall 9 kW heater.
🔒 2 Year Warranty Included
