Leil Black Cube Classic 4-Person Cabin Sauna

Constructed from 40mm (1.57") thick thermally treated pine walls, this sauna kit delivers exceptional dimensional stability and natural resistance to the elements without relying on chemical treatments. The thermal modification process removes excess moisture from the wood, resulting in a rich tone and reliable durability through seasonal weather shifts. Inside, the two-level thermo-alder benches feature integrated skirts for an ergonomic layout and maintain low thermal conductivity so seating stays comfortable during high heat.

Powering this unit requires a dedicated 240V electrical connection, with a 6 kW heater recommended for standard configurations or a 9 kW heater if opting for the back-wall panoramic window upgrade. Assembly is structured as a DIY kit that typically takes a team of two to three people several hours to complete, involving the alignment of thick wall panels, mounting the heavy 8mm black tempered glass front, and installing the shingled roof. Ventilation openings are built into the layout to maintain proper airflow and consistent heat distribution across the 80" W x 54" D x 80" H interior.
