The HUUM CORE Black Electric Sauna Heater combines modern Nordic design with efficient performance in a compact, refined form. Crafted in Estonia, where sauna culture runs deep, the CORE Black features a stainless-steel structure with a matte black metal casing and matching inlay for a cohesive, contemporary look.

Designed for versatility, the CORE is available in multiple power ratings to suit a wide range of sauna sizes. Its small footprint and minimal safety distance requirements make it ideal for tighter layouts, including installations where the heater can be partially or fully embedded into the sauna bench.

The CORE heats the room quickly, and its open stone housing allows users to pour water over the stones to create steam as desired. When paired with a UKU Control (sold separately), the heater offers convenient, consistent operation from an intuitive interface.

With durable construction and a 3-year private-use warranty, the HUUM CORE Black delivers long-lasting performance and a visually striking centerpiece for any modern sauna.
