HUUM Electric Sauna Heaters

HUUM electric sauna heaters are where ancient Estonian sauna traditions meet modern Nordic design. Inspired by the natural world, their forms echo water drops, cliffs, and organic shapes - bringing a touch of nature’s balance into the sauna room.

At the heart of every HUUM heater is the stone. With unusually large stone capacities, HUUM designs create soft, consistent steam (löyly) that honors traditional sauna bathing. The heaters are engineered for both efficiency and longevity, using stainless steel and other durable materials, while minimizing waste through sustainable design practices.
