HUUM CORE BK/ST

HUUM CORE BK/ST

The HUUM CORE BK/ST is a customizable electric sauna heater designed for projects where the heater can become an integrated part of the sauna interior. Available in 6.5 kW, 9 kW, and 10.5 kW configurations, it accommodates sauna rooms from 177 to 566 cubic feet, depending on the selected output. Unlike finished CORE models, the CORE BK/ST arrives without a finished exterior casing, allowing custom exterior panels to be created using compatible materials such as ceramic tile, stone, glass, or wood. Its compact 12.2 × 12.2 in footprint provides flexibility for space-conscious layouts and allows the heater to be integrated into a compatible sauna bench when installed according to HUUM requirements. Designed, engineered, and manufactured in Estonia, the CORE BK/ST features industrial-quality stainless steel heating elements, a 66 lb stone capacity, adjustable legs, and compatibility with HUUM UKU control systems. All supplied configurations operate on 240V single-phase power. Required HUUM UKU control and 66 lb of sauna stones (2 boxes), sold separately. Custom exterior finish materials are not included.

About Rodeo

At Rodeo we're on a mission to create the best saunas in the world. It all started with a simple realization - existing brands were either overpriced or cheap knock-offs.

So we built the brand we wished existed. A perfect balance of great materials, honest craftsmanship, and clean design at a fair price. We focus on what actually matters - crafting great products that hold up to real, everyday use.

We build with the belief that products should become part of your routine, not end up in a landfill. No trends. No gimmicks. Just great saunas, made the right way by people who care about their craft.

We make saunas for folks who deeply love the art of rest, recovery and relaxation after a hard days work.
