If you want a stone-forward heater in a compact footprint, CLIFF 9 is built around a tall, slim body with 75 kg / 165.4 lb stone capacity and an 8–13 m³ room target—supporting a sauna feel that emphasizes mild, long-lasting steam while helping you preserve layout flexibility. The internal air tunnel design is intended to speed heating while supporting airflow and component longevity, making it a practical choice for frequent home use.
At the brand level, HUUM positions the CLIFF line around Nordic-inspired design, stainless steel construction, and an environmentally conscious design approach in how the heater body is produced. The line is also presented as award-recognized, pairing a clean visual profile with the functional requirements of a modern electric sauna system.
For long-term ownership, the heater is designed to integrate with a full control-and-stone setup: it requires a UKU control system and properly sized stones, and it supports design options like bench embedding and coordinated control panel styles to help keep your sauna build cohesive.
