Description

The HUUM HIVE 18kW Electric Sauna Heater is the ultimate high-capacity solution for large private and commercial saunas. Engineered for sauna rooms between 636 and 989 cubic feet, this striking floor-standing heater blends modern elegance with powerful heating performance.

Designed to hold an impressive 528 pounds of stones, the HIVE 18 delivers exceptionally smooth, consistent heat with rich, long-lasting löyly. More exposed stones increase steam capability and help maintain stable temperatures even in heavy-use environments such as health clubs, spas, wellness centers, and athletic facilities.

Crafted in Estonia with HUUM’s signature stainless-steel construction, the HIVE 18 includes a pre-installed air tunnelthat reduces heat-up time and extends the life of the heating elements. Pair this heater with a HUUM UKU Control System for precise, professional-grade temperature management — including app-based control via Wi-Fi options.

Whether in a commercial setting or a large residential sauna, the HIVE 18 combines durability, beauty, and authentic European sauna performance.
