The HUUM CORE electric sauna heater features a compact, floor-mounted design with a contemporary CORE Black matte metal finish that integrates seamlessly into modern sauna interiors and custom bench layouts. Engineered in Estonia, it holds up to 66 lbs of sauna stones to produce smooth, abundant steam and balanced humidity when water is ladled over the rocks. Available in 240V (6.5 kW) and 208V (4.8 kW) configurations, it delivers efficient, consistent heating performance for a range of sauna room sizes. Designed for use with HUUM UKU control systems (sold separately), it supports convenient mobile app control for remote start and temperature adjustments. Built with durable metal construction and IPX4 splash resistance, the CORE heater is backed by a 3-year limited residential warranty and a 1-year limited commercial warranty (heating elements excluded).

  • Customizable modern design – Slim, space-conscious construction with a contemporary CORE Black matte metal finish allows seamless integration into custom bench layouts or modern sauna interiors, delivering both refined European aesthetics and powerful performance in one cohesive centerpiece.
  • Minimal safety clearances – Requires as little as 2 inches of side clearance, making it ideal for compact sauna rooms or space-sensitive installations while maintaining safe operation and full heating capability.
  • Generous stone capacity – Holds up to 66 lbs of sauna stones, creating abundant, smooth steam when water is ladled over the rocks for a softer, more enveloping heat experience that enhances comfort and humidity balance.
  • Smart app control compatibility – Fully compatible with HUUM UKU controls, enabling remote start and temperature adjustments through the HUUM mobile app for convenient preheating and personalized session management from anywhere.
