DROP electric sauna heater is inspired by the purest element of nature – a drop of water. The sleek and rounded design adds a touch of elegance to any sauna interior.
In 2015, the DROP was awarded with prestigious Red Dot design award. In addition to its aesthetic appeal, the DROP heater boasts several outstanding features.
This wall-mounted heater, despite its compact size, can accommodate up to 55 kg of stones, which is more than most wood-burning heaters. It provides a gentle and long-lasting steam and comes with durable stainless steel details. With its impressive features and superior appearance, the DROP sauna heater is a must-have for any sauna enthusiast.
We strongly recommend including a safety railing in your sauna—either a custom design from your builder or our HUUM safety railing—for enhanced safety and comfort.
