The HUUM DROP 4.5 is a compact masterpiece—an award-winning sauna heater inspired by the most essential element of the sauna ritual: water. Designed in the iconic shape of a falling droplet, this 4.5kW wall-mounted heater introduces modern artistry into smaller sauna rooms while delivering an exceptional, steam-rich heat experience.
Perfect for sauna spaces 106 to 248 cubic feet, the DROP 4.5 features an impressive 122-pound stone capacity—a volume usually found in much larger heaters. This abundance of exposed stones produces a deeper, softer, and more consistent heat, while enabling powerful steam bursts when water is poured over the rock bed.
Crafted from premium stainless steel in Estonia and recognized with the prestigious Red Dot Design Award, the DROP Series combines aesthetic elegance with elite engineering. Direct stone-to-element contact ensures efficient heat transfer, quicker warm-up times, and a remarkably satisfying sauna experience, even in compact rooms.
Compatible with all HUUM UKU Controls, including Wi-Fi systems that allow you to preheat your sauna from your smartphone, the DROP 4.5 delivers high-end performance, minimalist beauty, and advanced functionality in one understated, design-forward form.
