This HUUM DROP 4.5kW Electric Sauna Heater Package (UKU WiFi Control) comes complete with the traditionally designed DROP 4.5kW sauna heater, UKU WiFi control, and sauna stones - everything you need to build your dream sauna experience. The package has been combined for use in sauna rooms from 106 to 248 cubic feet.

The HUUM DROP 4.5kW Electric Sauna Heater blends Nordic artistry with advanced engineering, inspired by the pure simplicity of a drop of water. Its smooth, rounded shape brings a sculptural elegance to any sauna interior while maximizing performance within a compact footprint.

Despite its sleek design, the DROP accommodates up to 121 lb (55 kg) of sauna stones—more than most wood-burning heaters—ensuring steady, even heat distribution throughout each session. Built with durable stainless-steel components, this wall-mounted heater offers exceptional longevity and refined craftsmanship.

Honored with the Red Dot Design Award in 2015, the DROP embodies both timeless design and functional innovation, making it an outstanding choice for modern sauna spaces.

For added safety and visual harmony, pair the DROP with a HUUM safety railing or a custom-crafted guard.
