Kohler C1 2-5 Person Indoor Traditional Sauna Kit – Graphite Grey Spruce

Kohler C1 Indoor Sauna Kit – Graphite Grey Spruce | Up to 5 Persons

The Kohler C1 Indoor Sauna is a beautifully engineered indoor sanctuary crafted for a premium traditional sauna experience. Featuring a refined Scandinavian Spruce interior and a Graphite Grey Spruce exterior, this modern cabin blends durability, comfort, and architectural elegance. Designed for both freestanding and alcove installation, it offers flexibility for home gyms, bathrooms, basements, or dedicated wellness spaces. The tempered glass door and windows allow natural light and visibility while thick mineral wool insulation and high-grade rubber seals maintain excellent heat retention.

The C1 comes complete with a freestanding FERO Electric Sauna Heater, sauna stones, a matching heater guard, and an external digital control panel for effortless temperature, session, and lighting adjustments. Thoughtful design touches—such as warm white 2700K indirect backrest lighting, cool-to-touch beech wood handles, and dual thermostatic control—ensure a relaxing, repeatable sauna session. Available in three cabin sizes and with or without an integrated floor, the C1 delivers premium build quality and UL-certified safety for a truly elevated indoor sauna environment.
