The HUUM Hive Mini sauna heater collection holds three sizes, each available as a bare heater or a package with a control and stones. This round floor standing sauna heater suits a smaller sauna, with a stone capacity of 330 pounds of sauna stones. You can choose the Hive Mini 6, Hive Mini 9 or Hive Mini 10.5 to match your room. Start with your room measurements, then decide which control you want.


The smaller round floor heater

Made in Estonia, the Mini has a stainless steel body on adjustable legs. Its stones sit directly on the heating elements for soft heat and long-lasting steam in a traditional sauna heated with rocks. You can explore the maker’s other lines on the HUUM brand page. For choices across brands, browse our sauna heaters and wood burning stoves or our electric sauna heaters.

Choose from three sizes

The Hive Mini 6 is 6 kW for 176 to 282 cubic feet, and the Hive Mini 9 is 9 kW for 317 to 530 cubic feet. The Hive Mini 10.5 is 10.5 kW for 353 to 706 cubic feet. Each is about 18 inches across and 29.5 inches tall, weighing 31 to 36 pounds empty. For large or commercial sauna rooms, consider the bigger round Hive, or explore the slim Cliff column when floor space is limited.

The control, stones and included insert

Each Mini needs a HUUM UKU control outside the hot room, without an extension box. Choose standard UKU, Wi-Fi, Mirror or Gold, with phone starting through the HUUM mobile app on a Wi-Fi version. Add the control and ten boxes of stones on the bare heater page, or choose the package with its control, sensors, cables and 330 pounds of rounded olivine stones. The included air tunnel speeds heating by about a quarter and reduces the stone load to about 265 pounds. A safety rail, embedding flange and reflector panel are optional add-ons.

HUUM Hive Mini or the full Hive?

The Mini is 18 inches across, holds 330 pounds of stones and needs only a HUUM UKU control. The Hive is 22 inches across, holds 552 pounds and also needs the UKU extension box. Most home saunas take the Mini, while the Hive offers 12 to 18 kW.

Does the HUUM Hive Mini come with a control and stones?

The bare heater comes with adjustable legs, the insert and manual. You add the control and ten boxes of stones on the page. The package includes a HUUM UKU control with sensors and cables, plus 330 pounds of rounded olivine stones. Either listing offers standard UKU, Wi-Fi, Mirror or Gold.

What does the air tunnel insert do?

The insert sits among the stones and speeds heating by about a quarter. Fitting it reduces the load from 330 to about 265 pounds. Leave it out for the full load and soft, lasting steam. It comes in the box with your HUUM Hive Mini.
