Description
The HUUM STEEL Mini 3.5 kW is the most compact electric sauna heater in HUUM’s STEEL line, engineered for small home and cabin saunas across the United States. Its ultra-slim, wall-mounted body and exceptionally short safety distances let it fit sauna rooms from roughly 106–177 ft³ (3.5–6 m³) without sacrificing steam quality.
Built from premium stainless steel, the STEEL Mini heats quickly and evenly while standing up to years of daily use. Its open stone bed holds a generous load of sauna stones, producing the soft, rich löyly of a traditional Finnish sauna rather than harsh, dry heat.
Compact size makes it ideal for backyard cabins, indoor home saunas and boutique wellness rooms. Paired with a HUUM UKU controller (Wi-Fi or local, sold separately), the STEEL Mini supports remote start, scheduling and precise temperature control from your phone.
