CLIFF electric sauna heater has a stunning natural stone surface that reflects the nature of Nordic cliffs. But what sets this sauna heater apart is not only its eye-catching appearance but also its efficient and environmentally conscious design.
The body of the heater is made from cutouts of a stainless steel sheet created during the production of STEEL electric heaters, which eliminates metal waste and ensures full use of all material.
The heater has small safety distances and a slim shape, making it suitable for smaller sauna rooms. The internal air tunnel accelerates heating by 25% and extends the life of the heating elements.
With a large amount of stones, the CLIFF heater provides mild and long-lasting steam, ensuring a relaxing sauna experience.
In 2021, the CLIFF heater won the Red Dot Design Award for product design.
We strongly recommend including a safety railing in your sauna—either a custom design from your builder or our HUUM safety railing—for enhanced safety and comfort.

CLIFF and STEEL sauna heaters that have minimized the ecological footprint
CLIFF electric sauna heaters form an inseparable pair with STEEL electric sauna heaters. One could not exist without the other. These two sauna heaters are produced from the same stainless steel sheet. The fins of CLIFF sauna heaters are made from the cutouts of STEEL sauna heaters, which ensures that all the material is utilized and there is no residual waste.
Our mission is to find measures to ensure sustainable production with the smallest environmental footprint, so that we can hand nature in its current beauty down to future generations.
