HUUM DROP Series 4.5kW Sauna Heater

HUUM DROP 4.5kW Sauna Heater

Inspired by the purest element in nature—a single drop of water—the HUUM DROP 4.5kW sauna heater brings sculptural elegance to the traditional sauna. Its rounded, organic design softens angular interiors while creating a refined, modern focal point.

Beyond its striking appearance, the DROP 4.5kW delivers exceptional performance. With an impressive 122 lb stone capacity—exceeding many wood-burning stoves—it produces a soft, consistent heat and long-lasting steam. Direct contact between stones and heating elements ensures efficient heat transfer and a smooth, balanced sauna experience.

Please Note: A UKU control system and sauna stones are required for operation and are sold separately.
