Description
HUUM STEEL 9.0STU Pkg combines a 9 kW electric sauna heater, UKU control, and 330 lb sauna stones for sauna rooms 283–460 ft³. Designed for compact and modern builds, this floor-standing heater pairs a slim footprint with fast heat-up and a stone-heavy core for a gentle, even steam.
At the center of this kit is the STEEL 9.0 kW heater: a tall, stainless-steel enclosure that showcases the stones while keeping safety distances small for tighter layouts. An internal air tunnel is engineered to improve airflow and speed sauna heating, while the direct contact between stones and heating elements supports a steady, comfortable warmth. With a 330 lb stone capacity, you get the stone volume many sauna users want for longer, milder heat that feels consistent throughout the room.
Control is handled through the included UKU system, giving you straightforward command of on/off, time, temperature, and delay start scheduling. The system supports installation inside or outside the sauna room, uses a separate main control module, and includes both a temperature sensor and a door sensor to help keep heat inside the space. Temperature is adjustable within the 104–230°F range, and the delay start function can be set up to 48 hours in advance. If you want remote control capability, the control system supports an optional built-in Wi-Fi interface for use with a mobile app (configuration dependent).
This package also includes 330 lb of round sauna stones selected to complement the heater’s design. The stones are olivine diabase, with a rounded 1"–2" (3–5 cm) size range and high-heat capacity characteristics for stable heat retention. Whether you’re outfitting a new sauna room or upgrading an older heater/control combination, the STEEL 9.0STU package brings the key components together in one coordinated set.
About the brand: HUUM designs and manufactures sauna products in Estonia, with a focus on clean, modern aesthetics and engineering choices that support practical installation and long-term use. The STEEL series emphasizes a compact footprint, stainless-steel construction, and a stone-forward layout intended to deliver a milder steam experience while supporting responsive control through the UKU system.
