          Heats to 230°F

          HUUM electric sauna heaters get hotter than any other in North America, reaching up to 230°F. They use SGS standards, which are fully accepted in the US, allowing saunas to achieve desired temperatures effortlessly.

          Other sauna heater companies are UL-listed and can't go above 194°F. This often results in lower temperatures at bench level, making it difficult to achieve the desired sauna experience.

          Nordic Cliffs Design

          HUUM Cliff has a beautiful natural stone surface that reflects the nature of Nordic Cliffs. The Cliff sauna heater has received the internationally recognized reputable Red Dot product design award for its eye-catching design and masterful craftsmanship.

          Superior Steam

          The amount of metal used in HUUM sauna heaters is very small – this ensures that the majority of the heat derives from the stones, and not from the metal. This maximizes the proportion of beneficial negative ions in the air, which is also high in the traditional wood-heated sauna.

          This and the exceptionally large quantity of sauna rocks are the secret ingredients of the curative, gentle and durability that stands the test of time steam of our sauna heaters.

          Control Unit Options

          HUUM sauna control system has 2 different configurations; local and WiFi enabled. When you have a local control system, you can control the sauna from the control panel placed on the wall outside of your sauna room.

          When you have a WiFi-enabled system, you can control the sauna through an app on your phone (regardless of your location), or from the control panel itself.

          Highly Recommend This Company

          The team at Soaknsweat was absolutely incredible. I honestly didn’t think customer service like this still existed. Kris and the crew actually answered the phone, patiently walked me through every question, and helped me make several key decisions for my sauna setup. They followed up quickly, were extremely professional, and truly earned my business and recommendation. Their YouTube content was also a huge help during the planning phase — and one of the main reasons I chose to order from them. Thanks, team!

          Building Phase

          I’m currently in the process of designing and building a sauna. After a lot of online research and frustration, I discovered Soak 'n Sweat — and it was a game changer. Their educational page covers every aspect of sauna design and answered nearly all my questions through detailed articles and videos. When I reached out via chat, Kris patiently addressed the rest of my questions without any pushy sales tactics. These folks really know their stuff, provide great products, and make the whole experience smooth and informative. Thank you!

Their knowledge, patience, and genuine willingness to help made the entire experience smooth and stress-free. I’m extremely impressed with their customer service and highly recommend Soak 'n Sweat to anyone looking for quality products and exceptional support.
