Designed for saunas where space efficiency and performance must work together, the HUUM STEEL 6 delivers powerful, consistent heat in a slim, modern form. This 6.0kW electric sauna heater features a large stone capacity combined with remarkably small safety distances, making it an ideal choice for sauna rooms with limited space. It is engineered for sauna environments ranging from 177 to 318 cubic feet.

Thanks to its well-optimized internal structure, the STEEL 6 requires minimal clearance from surrounding walls—down to approximately 2 inches (5 cm) on smaller models and 4 inches (10 cm) on larger models. This space-saving design allows for greater flexibility in sauna layouts while maintaining safety and performance.

The intelligently engineered stone chamber holds more stones than most heaters in its power range, producing a more consistent, high heat and improved steam capability. The result is a smoother, more balanced sauna experience with better heat retention and comfort throughout each session.

With its clean, contemporary aesthetic, the STEEL 6 enhances the look of any home sauna while delivering professional-grade performance. Compatible with HUUM UKU sauna controls (sold separately), including Wi-Fi–enabled options, it offers convenient control and customization—allowing you to manage your sauna settings on-site or from your smartphone.
