The HUUM HIVE Electric Sauna Heater is the powerhouse of the HUUM lineup — a larger, more robust version of the acclaimed HIVE Mini. Purpose-built for spacious environments such as commercial spas, wellness centers, and large home saunas, the HIVE series delivers exceptional performance, capacity, and durability.

Available in 12 kW, 15 kW, and 18 kW models, this floor-mounted heater is engineered to meet the demanding heating requirements of large sauna rooms while maintaining the sleek, modern aesthetic that defines HUUM.

Engineered for Large Spaces

The HIVE heater boasts a massive stone capacity of up to 250 kg (551 lb) — equivalent to 17 boxes of HUUM sauna stones (33 lb each). This exceptional capacity allows the heater to store and radiate heat evenly over an extended period, creating a smooth, consistent temperature that transforms the sauna experience.

Designed to reach temperatures of up to 110 °C (230 °F), the HIVE efficiently fills even the largest sauna rooms with gentle, lasting warmth. Its impressive stone bed also enables the creation of rich, soft steam when water is poured over the rocks — ensuring a luxurious and authentic sauna atmosphere.

Modern Technology Meets Traditional Craftsmanship

Like all HUUM models, the HIVE heater seamlessly combines natural aesthetics with cutting-edge functionality. Optional Wi-Fi control integration via the UKU app allows you to remotely preheat your sauna, ensuring it’s ready the moment you are.

Every element of the HIVE is crafted for efficiency, durability, and safety, making it ideal for both residential and commercial applications.
