This HUUM STEEL 10.5kW Electric Sauna Heater Package (UKU WiFi Control) comes complete with the traditionally designed STEEL 10.5kW sauna heater, UKU WiFi control, and sauna stones - everything you need to build your dream sauna experience. The package has been combined for use in sauna rooms from 354 to 566 cubic feet.

The HUUM STEEL 11 Electric Sauna Heater combines refined aesthetics with powerful performance, making it an ideal choice for modern home saunas. Its slim, vertical design minimizes required safety distances, allowing efficient installation even in smaller sauna rooms.

Engineered for superior airflow, the integrated air tunnel promotes faster heating while protecting internal components for long-term reliability. Despite its slender build, the STEEL accommodates a generous amount of sauna stones to deliver steady, evenly distributed warmth throughout each session.

Encased in polished stainless steel, the HUUM STEEL 11 adds a sophisticated architectural accent to any sauna space.

For optimal comfort and safety, pair the heater with a HUUM safety railing or a custom-designed guard.
