HUUM DROP 7.5 — Wall-Mounted Electric Sauna Heater (7.5kW)

Inspired by the pure, elemental form of a falling water droplet, the HUUM DROP 7.5 is a sculptural, award-winning electric sauna heater that instantly elevates any modern sauna space. Compact, elegant, and engineered for performance, this 7.5kW wall-mounted heater delivers exceptional heat for sauna rooms from 248 to 389 cubic feet.

DROP’s hemispheric design softens the angular structure of a traditional sauna, transforming the heater into a true architectural statement. Yet its visual appeal only enhances its performance—its 122-lb stone capacity rivals many full-size stoves, producing a smooth, deep, long-lasting heat with superior steam when water is ladled onto the stones.

Crafted from premium stainless steel in Estonia, DROP is engineered for efficiency. The stones sit directly against the heating elements, improving heat transfer, boosting steam quality, and accelerating warm-up time. Its compact installation footprint makes it ideal for smaller to mid-sized saunas looking for high-end performance without sacrificing space.

Compatible with the full suite of HUUM UKU Control Systems—including Wi-Fi options that let you preheat your sauna from anywhere—the DROP 7.5 delivers a premium sauna experience with modern convenience built in.
