The HUUM CORE ST Aspen Electric Sauna Heater is designed to complement a wide range of sauna interiors while delivering consistent heating performance in a refined, natural aesthetic. Crafted in Estonia, the CORE ST Aspen model features a stainless-steel structure paired with Aspen side panels and stainless steel inlay finish to help it blend seamlessly with surrounding materials.

Offered in multiple power ratings to suit various room sizes, the CORE is engineered for compact spaces, benefiting from its small footprint and minimal safety distance requirements. Its adaptable form allows for flexible placement, including the option to embed the heater within the sauna bench for a built-in look.

The open stone housing distributes heat efficiently, and users can pour water over the stones to create steam as desired. When paired with a UKU Control (sold separately), the heater provides convenient operation and precise control settings.

Supported by a 3-year warranty for private use, the HUUM CORE ST Aspen Sauna Heater brings together modern Nordic design, customizable detailing, and durable construction for a clean, cohesive addition to your sauna.
