The HUUM HIVE 15kW is a 15 kW floor-mounted electric sauna heater designed for residential and commercial sauna rooms of 530 to 883 cubic feet. Its circular design, inspired by traditional sauna baskets, gives the heater a minimalist Nordic look while maximizing stone exposure for soft, consistent heat. The stainless steel construction is built for long-lasting durability in demanding sauna environments, and the stable, freestanding body stands on adjustable legs. The HIVE is designed and manufactured in Estonia.
The open stone basket holds up to 550 lbs of sauna stones for lasting heat retention and lets water be poured from multiple angles for rich, long-lasting steam. Sauna stones are sold separately. A compatible HUUM UKU control unit (sold separately) is required, with GLASS, CLASSIC and WOOD control panel styles available. When paired with a Wi-Fi-enabled controller, the HUUM mobile app allows remote start and temperature adjustments. The heater carries an IPX4 splash-resistant rating, is SGS certified to US and Canadian safety standards, and requires hardwired installation by a licensed electrician.
