Modern Scandinavian Design with Traditional FERO Heat

Transform your home into a refined wellness retreat with the KOHLER C1 Indoor Sauna. Its Graphite Grey exterior, Scandinavian spruce interior, Obeche wood seating, tempered glass, and warm indirect lighting create a sophisticated setting for traditional sauna bathing. The C1 is designed for flexible freestanding or alcove installation and is available in configurations for up to two, three, or five people.

The sauna combines a freestanding FERO electric heater with sauna stones, dual thermostatic control, and an external digital control panel. Its Aerotherm ventilation system provides air exchange, while 2-1/8-inch mineral wool insulation and rubber door seals help retain heat.

Designed for Modern Indoor Wellness

The C1 combines contemporary architecture with traditional sauna construction. Its tongue-and-groove wall, floor, and roof connections create a clean appearance, while the Graphite Grey exterior contrasts with the lighter Scandinavian spruce interior.

Because the C1 family is offered in multiple sizes, customers can select a configuration appropriate for their available space and desired capacity. Current KOHLER specifications identify 2-, 3-, and 5-person configurations.

Scandinavian Spruce & Obeche Wood

The interior uses Scandinavian spruce, paired with solid Obeche wood benches and backrests. The five-person specification also includes a stool, headrest, and additional seating elements.

FERO Electric Heater & Sauna Stones

The C1 uses a freestanding FERO electric sauna heater with sauna stones for traditional sauna bathing. Heater output varies by cabin size: the current KOHLER specifications list 4.5kW for the two- and three-person configurations and 9.0kW for the five-person configuration.

Water can be added to the heated stones according to the heater manufacturer's instructions to create the traditional sauna humidity experience.

Aerotherm Ventilation

The integrated Aerotherm ventilation system is designed to provide an adequate supply of oxygen and air exchange within the cabin. This ventilation system is a standard feature across the C1 configurations.

Thermal Insulation & Tempered Glass

The C1 uses 2-1/8-inch (54 mm) mineral wool insulation between the walls to support heat retention. The entry door uses 5/16-inch (8 mm) tempered glass, while rubber seals help limit warm-air loss.

Warm Indirect Lighting

A 2700K warm-white indirect lighting system illuminates the interior from behind the backrest. The external digital control panel allows the lighting to be managed along with temperature and session time.

Care & Maintenance

Keep the sauna interior clean and dry between sessions. Follow KOHLER's care instructions for the spruce, Obeche seating, glass, heater, stones, and control components.

Inspect the heater stones periodically and replace damaged or deteriorated stones according to the heater manufacturer's recommendations.

Warranty

Current dealer documentation lists a 5-year limited warranty for the KOHLER C1 family. Warranty coverage can vary according to the product configuration and applicable KOHLER terms, so the final purchase should reference the current warranty documentation.

Safety & Usage Information

Use the sauna according to KOHLER's installation and operating instructions.

The FERO heater requires appropriate electrical installation for the selected cabin size. Professional installation should follow applicable electrical codes and KOHLER/FERO requirements.

Use sauna stones and water only as directed by the heater manufacturer. Avoid excessive water application and exercise appropriate caution around hot surfaces and heated stones.

The original draft included claims regarding detoxification, circulation, immune function, and other medical benefits. Those claims have been removed or softened because the manufacturer's specifications support the sauna's features and traditional bathing experience, not guaranteed medical outcomes.
