HUUM CORE 10.5kW ST–Stainless Steel Trim Ring & Custom Panels | Electric Sauna Heater

The HUUM CORE ST electric sauna heater 10.5 kW is designed for those who want creative freedom and powerful, even heating in larger sauna rooms. Delivered without fixed side panels, it allows you to finish the exterior in materials that match your space—whether warm wood, tile, or stone—for seamless architectural integration. This version features a durable stainless steel top cover and includes an installation plate for wooden finishing to simplify custom cladding. Engineered in Estonia, it holds up to 88 lbs of stones to produce smooth, balanced steam when water is poured over the rocks. Designed for sauna rooms from 354–566 cubic feet (240V) or 265–424 cubic feet (208V), the CORE ST 11 combines high-capacity performance with flexible installation options. When paired with a compatible HUUM UKU control (sold separately), you can start and adjust your sauna from your mobile device for a fully personalized experience.
