The HUUM CLIFF Mini 4 is the ultimate compact sauna heater for small spaces that demand big performance. Designed for rooms between 106 and 177 cubic feet, this ultra-slim 4kW heater delivers powerful, consistent heat while maintaining the smallest safety distances of any heater in its class. If you're building a luxury micro-sauna or designing a tight layout where every inch matters, the CLIFF Mini 4 is engineered for you.
Despite its compact footprint, the CLIFF Mini 4 boasts an impressive 132-pound stone capacity, far exceeding typical heaters in this power range. This larger rock volume translates into softer, deeper, more luxurious heat—plus richer steam and a more authentic traditional sauna experience. Its vertical, Scandinavian-inspired design elevates the visual appeal of any modern home sauna.
With an internal air-duct system that accelerates heat-up times by up to 25%, direct stone-to-element contact for maximum efficiency, and removable ribs for perfect stone stacking, the CLIFF Mini 4 is both high-performance and elegantly refined. Pair it with any HUUM UKU Control—including full Wi-Fi capability for remote preheating—to bring smart convenience to your daily wellness routine.
Compact. Powerful. Beautifully crafted. The CLIFF Mini 4 is small—but delivers a sauna experience that feels anything but.
