The HUUM CORE BK electric sauna heater 9 kW is designed for sauna owners who want powerful, dependable heat with the freedom to match their space beautifully. Its open, case-free design allows you to customize the exterior with finishes like tile, stone, glass, or wood, creating a seamless, integrated look. The slim profile and minimal safety clearances make placement easy in modern layouts, including bench-integrated installations using an optional embedding flange. Designed for medium to larger sauna rooms, it delivers steady, enveloping warmth and responds beautifully when water is poured over the stones. With a 66 lb stone capacity, it produces soft, balanced steam for a classic sauna experience. Compatible with HUUM UKU control systems (sold separately), it allows convenient temperature management and remote operation when paired with a Wi-Fi-enabled control.
