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 has a large 122-pound rock capacity, more than most wood-burning stoves for a more intense steam sauna.
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.
