Description

The HUUM Hive is the powerhouse of the HUUM lineup — a free-standing electric sauna heater that looks more like a work of art than a technical appliance. Available in 12kW, 15kW, and 18kW, it's engineered for large sauna rooms and designed to be the visual and thermal centerpiece of any premium sauna environment.

The Hive's natural stone appearance and open frame create a striking contrast against wood interiors — stones visible through the structure, glowing with heat, turning the heater into a calming focal point rather than a utilitarian element. With a massive stone capacity for maximum thermal mass, the Hive delivers exceptionally soft, consistent heat and long-lasting steam — the hallmark of an authentic sauna experience. A built-in air tunnel improves heating efficiency and extends the life of the heating elements session after session.

This complete package includes the HUUM UKU Wi-Fi controller, extension box (required for heaters over 10.5kW), and sauna stones — everything needed for immediate operation. The UKU app lets you control temperature, set schedules, and preheat your sauna from anywhere via smartphone.

Professional electrical installation required. 240V.
