The Event Heater – with plunging steam-shock effect for commercial sauna cabins.

The innovative, premium class event heater will turn your sauna visit to a unique experience – the heated rock store can be slowly plunged down into the underlying illuminated water tank for a spectacular steam-shock effect. The steam shock event can be launched automatically or manually.

With the EOSphere the sauna world receives an attractive eye-catcher, which enriches every sauna landscape. It is an independent system and not suitable for heating the entire sauna.


In 2019 the EOSphere wins the GOLDEN WAVE innovation prize from SCHWIMMBAD + SAUNA in the category "sauna - infrared - steam bath - attractions & accessories":
