The Onyxia Cube is the architectural one: a rounded-square cabin of 42mm ThermoWood® Finnish pine, black outside, honey-toned inside, built in Europe and glazed however you want it — a full glass façade to face the view, or a solid wall for total seclusion. Four can sit; two can lie flat on the lounger configuration and watch the sky. ThermoWood®: durability by heat, not chemicals ThermoWood is Finnish pine thermally modified at high temperature — nothing added, everything stabilised. The result resists weather, insects and warping for years of British seasons, and ages to a naturally deep tone. Inside, spacious abachi benches stay comfortable at full temperature, with LED lighting for evening sessions. Choose your heater The Onyxia Cube is supplied without a heater so you can spec it your way — we recommend an electric stove from 4.5kW (see our sauna heaters range; we'll help you match size to cabin volume before you order).
