You or your builder finish its metal shields with tile, stone, glass, or wood to match your sauna. Its 9 kW output suits rooms of 283 to 460 cubic feet. The small safety gaps required around the CORE allow it to be built into a bench with only the stones showing. The box includes the heater, unfinished metal shields, cover strips and their screws, and adjustable legs. Choose stainless steel or black for the inlay finish on the page. A HUUM UKU control is required and sold separately. Pick UKU Local, or choose UKU Wi-Fi, Glass, Mirror, or Gold to start the sauna from your phone. You also need two boxes of stones, sold separately on the page. Need more heat for a larger room?
