The Complete Building Kit — Sauna Optimal in Thermo-Aspen is a comprehensive, all-inclusive sauna construction package that combines the exceptional durability and warm tone of thermally modified aspen with the natural lightness of aspen lining, reliable Harvia heating technology and everything needed to build a comfortable, high-quality home sauna from scratch. This is a true turnkey kit — from the frame, insulation and lining to the heater, control unit, LED lighting and wood care products — with no need to source individual components separately.
At the heart of this kit is the Harvia Wall 9kW electric sauna heater with Harvia Xenio digital control unit, delivering powerful, precise heating with accurate temperature and time control. The interior combines 126 pieces of aspen lining (STP 15×90mm) with a thermo-aspen modular kit, door, ventilation valve and armrest — creating a stylish, cohesive interior that blends the pale freshness of aspen with the noble warm tone of thermo-aspen. The 2×5m IP67 LED strip with dimmer provides soft, adjustable atmospheric lighting throughout the sauna.
