Crafted in Estonia where sauna is a way of life, the HUUM CORE BK/ST is constructed from stainless steel with different inlay finishes to choose from. The unit arrives without a casing for easy customization with ceramic tiles, stone, glass or wood to personalize the heater and make it your own. Available in a variety of power ratings to suit a wide array of sauna sizes, the CORE thrives in tight spaces where users can benefit from the heater’s small footprint and minimal safety distances. This clever design allows endless choices for placement, including the option to embed the heater within the sauna bench.
The CORE will swiftly heat the sauna room while you confidently ladle water upon the sauna stone surface to generate an abundance of steam. Pair the unit with a UKU Control for total command of your powerful sauna heater system.
Backed by a 3-year warranty for private use, the HUUM CORE BK/ST Sauna Heater is an embodiment of pure Nordic design, showcasing versatile functionality and durability while providing long-lasting relaxation.
