HUUM DROP Electric Sauna Heater

*Stones & Controller to be purchased separately*

(We recommend purchasing 4 x 15kg boxes of the Rounded Olivine Diabase Sauna Stones with this electric heater. You can find the recommended sauna stones here). 

The HUUM DROP electric sauna heater features high-quality materials with an award-winning design inspired by nature. 

The HUUM DROP sauna heater gets its inspiration from a water drop. The round design softens the angular interior of a sauna, giving it a touch of elegance. The compact wall-mounted DROP fits up to 55kg of stones, which guarantees a soft and long-lasting steam, similar to that of wood burning sauna heaters.  

HUUM heaters are manufactured in Estonia, where they are crafted from stainless steel and other high-quality materials. Combined with a stylish, minimalistic Nordic design, the HUUM DROP makes a statement piece in a home sauna.

Controller: Depending on the controlling system you will opt for, the heater can be purchased either with the  UKU Local (an easy-to use controller without Wi-Fi or mobile functionality), or the  UKU Wi-Fi Controller (a remote-control option with Wi-Fi capabilities).  

Heat Diverter and Heating Elements Retainer (this Huum "Upgrade Kit" is now included with the Drop 9kW model only):

The HUUM 9kW model includes an additional upgrade kit with a heat diverter and a heating elements retainer. These are NOT included with the 4.5kW and 6kW models.
