HUUM Sauna Rocks

HUUM Drop takes 132lbs 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 app enables one to heat the sauna from a smartphone

HUUM HIVE Mini smart app

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.
