Required for operation (sold separately): HUUM UKU control; 122 lbs of sauna stones (4 × 33 lb boxes, 5–10 cm (2″–4″) stones).
The HUUM DROP is inspired by the purest element in nature, a drop of water. Its rounded design softens the angular interior of a classic sauna for a more elegant look.
DROP isn’t only about looks. This compact wall-mounted heater holds 122 lbs of stones, more than most wood-burning stoves, for a soft, consistent heat and long-lasting steam. Choose 4.5, 6, 7.5, or 9 kW on 240V single-phase power; it works with the HUUM UKU control.
