HUUM HIVE 15kW 240V Electric Sauna Heater
The HUUM HIVE 15kW Electric Sauna Heater brings a bold, sculptural presence to larger sauna spaces. Inspired by the natural geometry of a beehive, this award-winning design highlights the visual beauty of sauna stones while delivering consistent, even warmth.
Engineered for performance and durability, the HIVE holds up to 250 kg (551 lb) of stones, ensuring steady heat distribution throughout extended sauna sessions. Built with high-grade stainless steel and designed to be positioned at the center of the room, it’s ideal for group or commercial use in spas, gyms, and wellness studios.
Starting in 2025, all HIVE models include an integrated air tunnel as a standard feature, improving airflow and overall heating efficiency. The heater is also compatible with HUUM’s mobile app, allowing easy and precise control over temperature and timing.
For enhanced safety and design harmony, pair the HIVE with a HUUM safety railing or a custom-built guard.
