Description
The HUUM STEEL 10.5 kW is a premium electric sauna heater engineered for homeowners and commercial operators in the United States who need fast, even heating in a compact footprint. Its ultra-slim vertical design saves floor space while still delivering powerful performance, making it ideal for indoor wellness rooms, backyard barrel saunas, boutique spas, and fitness centers.
The heater’s open-stone architecture and increased stone capacity allow it to produce rich, soft steam similar to a traditional wood-burning sauna. This creates a comfortable, stable sauna climate that supports both Finnish-style dry sessions and humid steam environments.
Built from high-grade stainless steel and equipped with high-efficiency heating elements, the HUUM STEEL 10.5 kW provides long service life, excellent heat retention, and responsive temperature control. The minimal metal surface and deep stone chamber enhance steam quality, resulting in a smoother heat curve and a more enjoyable sauna experience.
The HUUM STEEL series is also compatible with HUUM Wi-Fi and GSM smart controllers, letting you manage your sauna from anywhere directly through your smartphone—an ideal feature for modern home saunas and commercial facilities.
