Huum Hive Electric Sauna Heater (18kW) + WIFI Control Unit

The Huum Hive 18kW Electric Sauna Heater is designed for large saunas (18–35 m³), delivering intense, consistent heat that transforms any sauna session into a truly immersive experience. Its floor-standing design is as striking as it is functional — a statement piece built to perform.

Pair the Hive with the included UKU 18kW WiFi Controller and manage your sauna from your smartphone, wherever you are. Preheat on your way home, adjust the temperature mid-session, or schedule your next session — all through the intuitive Huum app.

Huum uses only premium materials and the largest-diameter heating elements on the market (13 mm) for exceptional longevity. The clean Nordic design heats up fast, holds heat longer, and produces rich, generous steam — session after session.
