Available in 2-, 3-, and 5-person configurations with freestanding or alcove installation, the C1 Graphite Grey adapts to your space rather than the other way around.\u003c\/p\u003e\n\u003ch4\u003eGraphite Grey exterior, premium spruce interior\u003c\/h4\u003e\n\u003cp\u003eThe deep Graphite Grey exterior is built to integrate into modern interiors dark, sophisticated, and architectural in feel. Step inside and the atmosphere shifts entirely: warm, welcoming Scandinavian spruce walls and ceiling envelop the space. The obeche wood bench and matching backrest are paired with 2700K warm white indirect lighting positioned behind them soft, gentle illumination that doesn't fight with the heat for your attention.

A FERO freestanding electric heater with sauna stones and a heater guard delivers traditional Finnish-style steam, while dual thermostatic control ensures every session is safe and repeatable.\u003c\/p\u003e\n\u003ch4\u003eSmart controls and ventilation done right\u003c\/h4\u003e\n\u003cp\u003eAn externally mounted digital control panel handles temperature, session time, and backrest lighting no need to interrupt your session to adjust settings. The Aerotherm ventilation system maintains a steady supply of fresh oxygen and proper air exchange throughout your session, so the air stays breathable even at peak heat. Beech wood door handles stay cool to the touch, and the freestanding-or-alcove design works for almost any indoor layout.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- HOOK SUMMARY --\u003e\n\u003cdiv class=\"sl-hook\"\u003eStriking Graphite Grey exterior, premium Scandinavian spruce interior, FERO electric heater, and tempered glass detailing the Kohler C1 Graphite Grey brings architectural sauna design into modern homes.
