HUUM HIVE Electric Sauna Heater 18 kW

The HUUM Hive Electric Sauna Heater is the ultimate solution for heating larger sauna spaces. As the big brother of the Hive Mini, this floor-mounted model delivers exceptional heating performance for spas, gyms, and commercial saunas, combining impressive power with a sleek modern design.

Available in 12 kW, 15 kW, and 18 kW options, the Hive boasts a massive stone capacity of up to 250 kg (551 lb) — equivalent to 17 boxes of HUUM stones. This extensive capacity ensures excellent heat retention and the ability to produce soft, consistent steam over extended sessions, closely replicating the traditional wood-burning sauna experience.

Despite its size and strength, the Hive shares the same refined craftsmanship and intelligent features as the Hive Mini. It reaches temperatures up to 110 °C, supports Wi-Fi connectivity through the HUUM UKU control system, and provides even, gentle heat distribution across the sauna.
