Bring the warmth of a traditional sauna to your own backyard with the Mande MW12 ThermoWood Outdoor Sauna. Designed for two to three people, this compact sauna gives you a private place to unwind, whether you’re winding down after a long day or sharing a session with family and friends. Its rounded cube shape and honeycomb-pattern shingle roof make it a standout addition to any garden or patio.
The MW12 is crafted from ThermoWood, a thermally modified wood treated with heat and steam rather than chemicals. The process helps the wood resist moisture, warping, and cracking, so your sauna holds up to the weather season after season with minimal upkeep. Its natural wood tones blend right into your outdoor surroundings, and two steel tension bands keep the structure solid and secure.
A wall of glass across the front, a tempered glass door flanked by two full-height windows, lets you take in the view while you enjoy the heat. Inside, an upper bench with a side return and a lower step bench let you choose your heat level, with backrests on both tiers for comfortable seating. LED lighting beneath the upper bench sets the mood for evening sessions, while two rear vents, two floor drains, and a removable floor grate keep the cabin fresh and easy to clean.
Getting started is simple, because professional assembly is included. Choose the Harvia KIP 6.0 kW electric heater with built-in controls, or pair it with the Harvia Xenio Wi-Fi controller to start heating your sauna from your phone. Every MW12 is backed by a 5-year structural warranty from Mande.
