Description
The HUUM DROP 4.5 kW is a compact wall-mounted sauna heater suitable for sauna rooms 3–7 m³ (106–248 ft³).
Despite its size, the DROP holds a large volume of stones, allowing it to deliver soft, even heat and a smooth, long-lasting steam (löyly). Compared to typical metal-heavy heaters, the higher stone capacity creates a more comfortable and balanced sauna experience.
Its rounded design, inspired by a water drop, adds a clean and modern look to any sauna. The DROP has also received the Red Dot Design Award, recognizing its distinctive design and quality.
This model is suitable for sauna rooms 3–7 m³ (106–248 ft³).
When paired with a HUUM UKU control system (Wi-Fi optional), you can conveniently control your sauna, including remote start through the HUUM mobile app.
