HUUM CLIFF 6 kW Electric Sauna Heater

The HUUM CLIFF 6 kW is a slim, floor-standing electric sauna heater designed to deliver strong performance in small to medium-sized sauna rooms. Developed as the larger counterpart to the Cliff Mini, it offers increased power options while maintaining a compact footprint and clean Scandinavian styling.

One of the CLIFF’s defining characteristics is its integrated air tunnel construction—a feature shared with HUUM’s most technically advanced models. This internal channel completely surrounds the heating elements, improving airflow through the heater while protecting internal components. As a result, the CLIFF heats up faster, operates more efficiently, and supports long-term reliability.

Rather than relying on exposed metal surfaces, the CLIFF focuses on stone-driven heat. With room for approximately 75 kg (165 lb) of sauna stones, it provides sufficient thermal mass to generate steady temperatures and smooth, lingering steam. While its stone capacity is slightly lower than the HUUM Steel, it follows the same design philosophy: controlled airflow paired with high stone volume for balanced heat and steam production.

The CLIFF’s visual profile sets it apart within the HUUM lineup. Its tall, narrow form allows installation in tighter layouts while offering a distinct alternative to wider heaters. Subtle design differences give it its own identity without sacrificing HUUM’s core principles of efficiency, durability, and understated aesthetics.

    The local and Wi-Fi sauna controls are essentially the same in terms of hardware and functionality. The key difference is that the Wi-Fi version includes an ID for connecting to the HUUM mobile app (Apple or Google Play). This feature allows you to remotely activate your sauna, enabling you to heat it up in advance, whether you're on your way home or just finishing a workout. It's designed to enhance convenience, ensuring your sauna is ready when you are.
