Kohler Indoor Sauna - Graphite Grey
Kohler C1 Indoor Sauna - Graphite Grey
The Kohler C1 in Graphite Grey brings a darker, more dramatic finish to Kohler's premium indoor sauna. Built for freestanding or alcove installation, it can anchor a dedicated room or tuck neatly into a wall recess. Tempered-glass door and windows keep the space bright and open, while obeche-wood benches and a matching backrest - lit by warm 2700K indirect lighting - make for a comfortable, traditional session. It arrives ready to run with a freestanding FERO electric heater, stones, and guard, all managed from an external digital control panel. Offered in three sizes, for up to 2, 3, or 5 people.
