Huum Hive Electric Sauna Furnace (18kW) + Local Control Unit

The Huum Hive 18kW Electric Sauna Furnace is engineered for large saunas (18–35 m³), delivering powerful, sustained heat that fills every corner of the room. Whether you're hosting a crowd or simply love a deeply heated sauna, the Hive 18kW rises to the occasion — heating up fast, staying hot longer, and producing rich, generous steam.

The included UKU 18kW Local Controller puts everything at your fingertips. Simple to operate, it features a child safety lock, door sensor, and overheating protection — so you can relax knowing your sauna is running safely and efficiently.

Huum combines thousand-year-old sauna traditions with contemporary Nordic design. The Hive uses the largest-diameter heating elements on the market (13 mm) for outstanding durability, while its elegant, minimalist form makes it a natural centerpiece in any sauna space.
