The HUUM DROP 9STU PKG features all the necessities to give your sauna space a touch of elegance.

The heart of this all-inclusive sauna heater package is the award-winning DROP 9.0 kW electric sauna heater engineered for spaces up to 530 cubic feet (CF). Choose between the advanced UKU Local digital sauna control, or the added convenience of an UKU Wi-Fi control package which allows you to preheat your sauna from anywhere with your mobile device.

The design of the HUUM DROP sauna heater is inspired by the purest element in nature – a drop of water. Its rounded design softens and compliments the angular interior of a classic sauna, giving it a touch of elegance. But DROP isn’t only about the looks. This compact wall-mounted heater can actually fit up to 122 lbs of stones, exceeding most wood-burning stoves and guaranteeing long-lasting steam.

Winner of the prestigious Red Dot Award in Europe for design, the HUUM DROP combines sculptural beauty with engineering excellence. It's exceptionally large rock capacity allows the sauna bather to ladle more water onto the stones for a more intense bathing experience while creating a more consistent, soft high heat. 

The available Wi-Fi control lets you preheat your sauna from anywhere. For bathers who want the absolute best sauna heater.
