The HUUM CLIFF is a slim, upright heater with a ribbed stainless steel frame around a tall stone column. The CLIFF Mini suits small saunas with limited space. It is operated by a separate HUUM UKU control.
Choose the heater on its own, or the complete package, which adds the stones and control the manufacturer lists as required for that model.
