CLIFF Mini 3.5 kW Sauna Heater

The CLIFF Mini 3.5 kW Sauna Heater is a compact, wall-mounted unit designed for small sauna rooms ranging from 123 to 212 cubic feet. With a slender design and extremely short safety distances, it delivers fast, even heat while maximizing usable sauna space. Its internal air duct allows the heater to warm up to 25% faster, and the design ensures direct contact between stones and heating elements for a longer, milder heat experience.
