HUUM CORE Black CORE Series Sauna Heater, Black Exterior, 6.5kW to 10.5kW

The HUUM CORE Black Sauna Heater is designed to reflect the individuality of its owner while delivering exceptional performance, rich steam, and a refined modern aesthetic. Combining powerful heating capabilities with minimalist Nordic design, the CORE creates a luxurious and immersive sauna experience.

Crafted in Estonia—where sauna culture is a way of life—the CORE Black features a durable stainless-steel construction wrapped in a sleek matte black metal casing with a black steel inlay for a cohesive, contemporary appearance. Its compact footprint and minimal safety distances make it especially well suited for tight spaces, offering flexible installation options including full integration into a sauna bench for a clean, built-in look.

Engineered for efficiency, the CORE heats sauna rooms quickly and evenly. Direct contact between the stones and heating elements allows users to confidently ladle water over the stones, producing soft, abundant steam. Available in multiple power ratings, the CORE accommodates a wide range of sauna room sizes and pairs seamlessly with HUUM UKU controls (sold separately) for complete control of your sauna environment.

Backed by a 3-year limited residential warranty, the HUUM CORE Black Sauna Heater embodies pure Nordic design—delivering durability, versatility, and long-lasting relaxation.
