Mande MW20 Outdoor ThermoWood Sauna – 5–6 Person

Bring the sauna experience home.

Create a dedicated place to unwind, warm up and spend long evenings outdoors with the Mande MW20. Designed for 5–6 people, this spacious outdoor sauna gives you room to enjoy a quiet session alone or share the experience with family and friends.

Handcrafted in Lithuania, the MW20 is constructed from genuine ThermoWood®, thermally modified for improved dimensional stability and resistance to moisture and decay. Its rounded profile, warm natural wood and expansive tempered-glass front give the sauna a distinctive architectural presence without sacrificing the traditional feel of a European sauna.

Inside, ThermoWood® benches provide generous seating, while integrated ventilation helps circulate air throughout the cabin. LED lighting beneath the benches creates a warm evening glow, and tempered-glass doors and windows bring natural light into the space during the day. Weather-resistant bituminous roof tiles help prepare the MW20 for year-round outdoor installation.
