The Huum Hive Electric Sauna Furnace (18kW), sold by Barrel Saunas, is engineered for large saunas of 18–35 m³, delivering powerful, sustained heat and rich steam. Paired with the included UKU Local Controller, it's built for hosting bigger sauna sessions with safe, simple operation.

The child safety lock and door sensor add protection for shared or family sauna use.
Barrel Saunas sources heaters built to genuine Nordic engineering standards, and the Huum Hive 18kW is a proven choice for larger sauna rooms and busier households. We back every furnace with clear installation guidance and support.
