The HUUM CORE ST electric sauna heater 6 kW is designed for those who want both creative freedom and a deeply satisfying sauna experience. Its open, customizable design allows you to finish the exterior in materials that match your space—whether warm wood, sleek tile, or natural stone—making the heater feel fully integrated into your vision. Despite its compact size, it delivers smooth, consistent warmth that fills the room comfortably and responds beautifully when water is poured over the stones, creating soft, enveloping steam. Minimal safety clearances make placement flexible, even allowing for seamless bench integration in modern layouts. When paired with a compatible HUUM UKU control (sold separately), you can start and adjust your sauna from your mobile device, ensuring every session is ready when you are and tailored to how you like to relax.

  • Fully Customizable Exterior: The CORE ST model arrives without a fixed outer casing, allowing you to finish it with ceramic tile, stone, glass, or wood. Optional wood slat sets are available to match your sauna’s interior design.
  • Minimal Safety Clearances: Requires only 2 inches of clearance from combustible materials, enabling creative layouts and flexible placement options in smaller sauna rooms.
  • Bench-Integrated Installation: Slim profile and low heat radiation allow the heater to be embedded directly into sauna benches using an optional embedding flange, creating a clean, built-in look without sacrificing performance.
  • Powerful Compact Performance: Available in 6.5 kW (240V) and 4.8 kW (208V) configurations for rooms up to 318 cubic feet. Holds up to 66 lbs of stones for smooth, gentle steam.
