STEEL Series 9.0kW Sauna Heater

Enjoy a superior sauna experience while adding beauty to your home sauna!

STEEL is a slim electric sauna heater with remarkably small safety distances, which makes it perfect for saunas with limited spaces. Thanks to its well-optimized structure, the safety distance from the walls is brought down to just 2" with smaller models and to 4" with larger models. The STEEL heater is also available in an even slimmer 3.5 kW wall-mounted model for very small sauna rooms.

Because of its intelligent design, the STEEL has a much higher stone capacity that other heaters, providing a more consistent, high heat, better steam capability, and an elevated bathing experience.

HUUM UKU sauna controls (sold separately) are available in a variety of finishes to suit your taste, and include W-Fi options so you can conveniently control your sauna from your smartphone!
