Key Features

Beehive-Shaped Design

Commercial Sauna

Flexible Placement

Control Unit Options

Beehive-Shaped Design

The round form of the HIVE sauna heater imitates a wild beehive. Stainless steel arcs surround the sauna stones with pure elegance and accentuate their natural beauty.

HIVE sauna heater represents the copious warmth of a Nordic sauna that unites people. It is the heart and focal point of the sauna. It’s pure pleasure to share stories and an authentic sauna experience beside it!

Commercial Sauna

Our commercial clients with extremely big saunas use multiple Hive’s in one sauna. You can wire multiple Hive’s together and run them with one control system. Usually the Hive’s are placed in the middle in these bigger saunas. Reach out to us for more information and details when you have a bigger sauna project coming up.

Flexible Placement

The free-standing round design of Hive offers a lot of flexibility for your sauna design. You can place the heater in the middle of your sauna room, in the corner, or embed it into the sauna benches.

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!

Kris even went above and beyond by giving me a call, making it easy to get answers right away — and it was after business hours! 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.
