HUUM CLIFF Electric Sauna Heater


HUUM CLIFF electric sauna heater has a stunning natural stone surface that reflects the nature of Nordic cliffs. It’s also super practical with extraordinarily short safety distances, making it the perfect solution for saunas where space is at a premium. Thanks to its efficiently designed structure, safety distances are reduced to a mere 2.4 inches for smaller models and 9.4 inches for larger ones. Additionally, CLIFF provides an ultra-compact 3.5 kW wall-mounted version, expertly crafted to accommodate even the smallest sauna rooms.

CLIFF is made with recycled cutouts from the HUUM STEEL, likely making it the most sustainably-made sauna heater on the planet.

Experience the perfect fusion of design, technology, and tradition with HUUM’s CLIFF Sauna Heaters. Elegantly crafted in Estonia, these slim electric sauna heaters are the epitome of Scandinavian style and innovation, perfect for transforming your sauna room into a sanctuary of relaxation.



Efficient Performance

With power options ranging from 3.5kW to 10.5kW, the CLIFF series offers a suitable choice for sauna rooms of varying sizes, from 123 to 600 cubic feet. They stand out with their remarkably small safety distances, making them ideal for smaller spaces. In addition, each unit heats up 25% faster due to an internal air duct, ensuring a warm and welcoming sauna environment in no time.

Superior Design and Construction

Every CLIFF Sauna Heater boasts a slender design that combines aesthetics and functionality. The heaters’ impressive stone capacities (133-165 lbs) contribute to a longer, milder heat. Removable ribs allow more accurate stacking of stones, enhancing direct contact between stones and heating elements for a superior sauna experience. All units are constructed from brushed stainless steel for longevity and a sleek, modern look.

Tailored to Your Needs

The CLIFF range includes the Mini 4, 6, 9, and 11 models, each catering to different needs and room sizes. From compact spaces to larger rooms, you’re sure to find the perfect fit. The heaters work seamlessly with UKU controls (sold separately) for easy and precise temperature adjustments. The CLIFF 11 also requires an UKU extension box for optimal performance.

Certified Quality

Backed by a limited 5-year warranty (excluding elements), our CLIFF Sauna Heaters reflect HUUM’s commitment to quality and customer satisfaction. All heaters are certified with CE, SGS, and IPX4, ensuring compliance with global safety and quality standards.

Embrace the essence of a sublime sauna experience with HUUM’s CLIFF Sauna Heaters. Explore the range and choose the model that suits your sauna room the best. Remember to purchase the necessary sauna stones and UKU controls separately for the ultimate sauna experience.
