HUUM Drop Sauna Heaters

What is a HUUM Drop sauna heater?

This wall-mounted sauna heater is made in Estonia, with a rounded stainless steel bowl shaped like a drop of water. Its shape won Europe's Red Dot design award. It has a stone capacity of 122 pounds, with sauna stones directly on the heating elements for soft heat and long-lasting steam. Explore the maker's other heaters on our HUUM brand page.

Choose from four sizes

The Drop 4.5 is 4.5 kW for 106 to 247 cubic feet, while the HUUM Drop 6 kW covers 177 to 353 cubic feet. The Drop 7.5 is 7.5 kW for 230 to 441 cubic feet, while the HUUM Drop 9 kW covers 282 to 530 cubic feet. All four are about 15 inches wide, 13 inches deep and 23 inches tall. They weigh 24 to 26.5 pounds without stones. For a smaller room, consider the slimmer Steel Mini wall heater, which is 6 inches deep.

The control, stones and package

Choose a HUUM UKU control in standard, Wi-Fi, Mirror or Gold versions as your sauna controller, mounted outside the hot room. You can schedule a start up to 48 hours ahead, and a Wi-Fi version lets you start the sauna through the HUUM mobile app. Add the control and four boxes of stones to the bare heater, or choose the package with both included. A safety rail and an embedding flange are optional add-ons. If you prefer a floor heater with more stones, the Hive Mini floor heater holds 330 pounds.

Your questions answered

Which HUUM Drop size do I need?

Measure your room in cubic feet. The Drop 4.5 covers 106 to 247, the Drop 6 covers 177 to 353, the Drop 7.5 covers 230 to 441, and the Drop 9 covers 282 to 530 cubic feet. Call us with your measurements to discuss the size.

Does the HUUM Drop need a separate control?

Yes, every Drop needs a HUUM UKU control mounted outside the hot room. There are no knobs on the heater. Choose standard, Wi-Fi, Mirror or Gold on the page, with phone starting through the HUUM app on a Wi-Fi version. The Drop does not need an extension box.

Does the HUUM Drop come with stones?

The bare heater comes without stones, so you add four boxes on the page. The package comes with 132 pounds of rounded olivine stones and a HUUM UKU control. The bowl holds 122 pounds directly on the heating elements. A bucket and ladle set is optional.

How should I stack the stones in a HUUM Drop?

The bowl holds 122 pounds from four boxes, resting directly on the heating elements. Users report stacking stones loosely with air between them, without wedging or pressing any against an element, and lifting them out to re-set every few months. The manual in the box shows the layout.

Heater or package: which HUUM Drop listing do I order?

Choose the package when starting from nothing, with the heater, a HUUM UKU control, sensors, cables and stones included. Choose the bare heater if you already have the control and stones or want to select them individually. You can add a safety rail or embedding flange to your HUUM Drop.
