Leil Como 3-180 3-Person Cabin Sauna

The Leil Como 3-180 utilizes 40mm thermally modified Scandinavian pine, known as ThermoWood, which provides superior moisture resistance and dimensional stability compared to untreated softwoods. This thermal treatment process uses heat and steam without chemicals, ensuring the walls will not warp, rot, or leak resin over years of frequent use. The 1.8-meter exterior width and single-level Aspen bench offer a practical footprint for three adults to sit comfortably, though stretching out fully to lie down is limited.

Heating performance relies on a separately purchased 6-9kW electric heater. Because of the 4.0 cubic meter interior volume and compatibility with advanced air-blending systems like Saunum, the cabin heats efficiently and avoids the common issue of cold floor air. The structure sits on adjustable M8x40 leveling feet with rubber pads, allowing stable placement on indoor surfaces, though a hard, level floor is required.

Assembly takes roughly 6 to 8 hours using pre-fabricated modular wall logs and requires three to four people, particularly to manage the heavy 8mm tempered glass front door safely. Electrical wiring must be handled by a certified electrician to meet local codes. Overall, this Estonian-crafted sauna balances minimalist design with durable, low-maintenance materials suited for indoor spaces.
