Leil Black Cube Comfort 6-Person Cabin Sauna

The Leil Black Cube Comfort is constructed from 40mm thick thermally treated thermo-pine walls, which provide excellent dimensional stability and resistance to weathering without relying on chemical treatments. The thermal modification process removes internal resins and moisture, helping the wood maintain structural integrity across seasonal temperature swings. Inside, the two-level thermo-alder benches feature integrated skirts for a polished look and low thermal conductivity, meaning they stay comfortable against the skin during high-heat sessions.

Heating performance relies heavily on your choice of stove, as the kit requires a separate 9 kW electric or wood-burning heater and stones. The 8mm black tempered glass front adds architectural presence while retaining heat effectively, though glass walls do require more thermal energy than solid wood. Electrical planning is essential: you will need a certified electrician to install a dedicated 240V line and a 50-amp breaker to support the heavy-duty heater requirements.

Delivered as a flat-pack DIY kit, assembly generally takes a small team of two to three people around six to eight hours using basic power tools. The package includes a weather-resistant shingled roof and a Nerostep non-slip plastic floor mat. Routine maintenance is straightforward, primarily involving basic exterior checks and cleaning, making this cabin sauna a solid long-term addition to a patio or backyard space.
