Know before you buy
The HUUM HIVE 12STUX is designed for larger sauna spaces, with a maximum capacity of 883 cubic feet. Ensure your sauna room is properly insulated to achieve optimal performance within this range.
Yes, this is a complete package that includes the HIVE heater, the UKU digital control system, an extension box, and the required olivine diabase stones. You will only need to provide the appropriate wiring and electrical components for your specific installation.
The 528 lbs stone capacity is a key feature that allows for sustained, mild heat rather than a harsh, dry blast. Because the stones have direct contact with the heating elements, they retain heat longer and produce a more consistent, rolling steam, known as löyly.
