HUUM HIVE 18STUX Sauna Heater Package – Power Meets Elegance for Large Sauna Spaces

Bring modern elegance and professional performance to your sauna with the HUUM HIVE 18STUX Package. This comprehensive set includes the HIVE 18kW electric sauna heater, the advanced UKU control system with optional Wi-Fi, the UKU extension box, and 528 lbs of natural sauna stones—ideal for large residential or commercial saunas up to 1,236 cubic feet.

Engineered in Estonia with precision and care, the HIVE 18 is known for its large stone capacity and ability to produce a soft, consistent heat. Its open structure allows for more exposed stones, resulting in longer-lasting warmth and a gentler, more luxurious steam experience. The robust stainless-steel construction and industrial-grade heating elements ensure durability in high-demand environments.

The included UKU control system allows full customization of your sauna experience, offering intuitive temperature, timer, and safety features. Optional Wi-Fi connectivity gives you remote access through the HUUM mobile app, while the UKU extension box enables integration for larger heaters like this model.
