HUUM DROP 6.STU Pkg w/ Wifi Control and Stones

DROP Series 6.0kW Sauna Heater Package

Experience sculptural design and powerful performance with a sauna heater package that delivers both elegance and exceptional heat.

The HUUM DROP 6.0kW Sauna Heater Package includes everything you need to elevate your sauna experience: the compact, award-winning DROP electric heater, UKU digital control (WiFi optional), and premium sauna stones. Designed for sauna rooms ranging from 177 to 318 cubic feet, this all-in-one package transforms your space into a refined and restorative retreat.

At the core of the package is the DROP 6.0kW wall-mounted heater — a perfect balance of minimalist design and high-performance engineering. You can choose between the UKU Local digital control for reliable in-room operation or upgrade to the UKU WiFi control, allowing you to preheat and manage your sauna remotely from your smartphone for ultimate convenience.

Inspired by the purest element in nature — a drop of water — the DROP heater features a smooth, rounded silhouette that beautifully contrasts traditional angular sauna interiors. More than just visually striking, this compact heater holds up to 122 lbs of sauna stones, surpassing many wood-burning stoves in stone capacity. The result is longer-lasting, softer heat and the ability to ladle more water onto the stones for rich, enveloping steam.

Recipient of the prestigious Red Dot Award for European design excellence, the HUUM DROP combines artistry with functionality. Its generous rock capacity ensures consistent heat distribution and an intensified steam experience for those who demand the very best from their sauna.

For those seeking premium design, powerful steam, and smart control flexibility, the HUUM DROP 6STU Package delivers an elevated sauna experience from the inside out.
