Sauna Cube 6-8 Person Outdoor Sauna

Polar Recovery Sauna Cube 6-8 Person Outdoor Sauna

Picture the whole family, or a few good friends, sharing the heat on a frosty evening, a ladle of water hissing on the stones and plenty of room for everyone to stretch out. The Polar Recovery Sauna Cube 6-8 Person is the largest cube in the range, a large outdoor sauna made for group sessions, with room for up to 8 people on long L-shaped benches. It turns the garden into a place where people gather, unwind and catch up, whatever the season.

The cabin is built from Finnish Thermowood, timber that has been heat-treated to reduce its moisture content, so it holds warmth very well without added insulation. Walls are 45mm thick with curved, barrel-style sides, the L-shaped benches are alder, the door is tempered glass and the roof is finished in Katepal black. Inside it measures 200 x 196 x 218.5cm (H x W x D), with a generous internal volume of 8.5m³, heated by the supplied Harvia Cilindro 9kW electric heater. A bucket, ladle, thermometer and two head rests are included, and externally it measures 210 x 205 x 240cm.

Choose the Wooden Front, a timber front with a glass door for a cosy, traditional feel, or the Glass Front for an open view out across the garden. For a classic wood-fired atmosphere, either front can be ordered with the Harvia M3 13kW wood burning heater instead of the electric heater. The 9kW electric heater needs a dedicated 50A supply with an isolator switch or commando socket, fitted by a qualified electrician; a three-phase supply isn't needed. Build it on a solid, level base and treat the timber inside and out with a breathable, sauna-safe finish to protect it and validate the warranty: 2 years with professional installation, or 1 year if self-assembled.

Please note: the Harvia Cilindro 9kW electric heater is the standard heater with this sauna. The Harvia Spirit WiFi heater is available as an optional upgrade, but it needs extra wiring work by your electrician, so please check with them before choosing it.
