HUUM Sauna Rocks
HUUM Drop takes 330lbs of sauna rocks
Product range of HUUM includes round sauna stones with a diameter of 5–10 cm / 2-4 in.
Olivine diabase sauna stones are enduring and their thermal capacity is high.
It’s recommended to use round sauna stones in HUUM sauna heaters. Round stones complement the design of the heaters and provide milder steam.
Why Use Our Rocks?
You can find your own stones but make sure you’re using the correct ones.
This video can help explain.
HUUM STEEL 11 Accessories
HUUM Rail S

The safety railing for CLIFF heaters helps to avoid accidental contact with hot heaters.
It consists of light wood profiles.
The safety railing is a good way to make the sauna event even safer and at the same time, it adds style to the heater.
HUUM Reflect S

Thanks to the placement of the HUUM reflector panel on the heater, it is possible to achieve half smaller safety distances from the walls.
It is made of stainless steel and is mounted on the side of the heater. The reflectors can be connected to each other.
HUUM Flange CS

The embedding flange is made of stainless steel and covers the uneven wooden edges around the heater, creating a clean and smooth finish.
The embedding flange is useful if you plan to install the sauna heater partially inside the sauna platform.
The HUUM Flange CS was designed for use with installation of the Cliff or Steel Series sauna heaters.
HUUM app enables one to heat the sauna from a smartphone

HUUM mobile app allows you to heat the sauna from your phone, wherever you are.
It doesn’t matter whether you are heading home from the office, finishing your evening jog or simply wish to have an unplanned rewarding sauna evening with your friends – just a few clicks on the smartphone, and a hot sauna awaits you!
Soft steam that resembles the traditional sauna
The amount of metal used in HUUM sauna heaters is very small – this ensures that majority of the heat derives from the stones, and not from the metal.
This maximizes the proportion of beneficial negative ions in the air, which is also high in the traditional wood-heated sauna.
This and the exceptionally large quantity of sauna rocks are the secret ingredients of the curative, gentle and long-lasting steam of our sauna heaters.
