Architectural Outdoor Sauna Comfort with Premium Wood & Traditional Heat

Transform your backyard into a refined wellness destination with the KOHLER C2 Outdoor Sauna. Designed as a freestanding outdoor cabin, the C2 combines a Douglas Fir exterior, Scandinavian spruce interior, Obeche wood benching, tempered glass, integrated lighting, and traditional electric sauna heat in a sophisticated architectural package. KOHLER offers the C2 in configurations for up to 3, 5, or 6 people, allowing the cabin size to match your available space and preferred capacity.

Extended roof eaves provide shade and weather protection, while 2.1-inch mineral-wool insulation, rubber seals, and tempered-glass door and windows help retain heat. Inside, warm 2700K indirect lighting behind the Obeche backrest creates a comfortable atmosphere for traditional sauna sessions.

The C2 also includes a freestanding FERO electric sauna heater with sauna stones and heater guard, along with an external digital control panel for temperature, session time, and backrest lighting. An Aerotherm ventilation system supports air exchange throughout the cabin.

Designed for Premium Outdoor Living

The C2 is more than a functional sauna cabin; its freestanding architecture is designed to become part of the surrounding outdoor environment. The Douglas Fir exterior provides a natural, refined appearance, while extended roof eaves add practical protection and shade.

The available configurations allow homeowners to choose a compact three-person cabin or a larger five- or six-person version for shared sessions.

Douglas Fir Exterior & Scandinavian Spruce Interior

The C2 pairs a Douglas Fir exterior with Scandinavian spruce interior walls. Inside, the seating and backrest use Obeche wood, creating a warm contrast against the spruce walls and glass surfaces.

The interior uses tongue-and-groove wall construction for a clean, seamless appearance.

FERO Electric Sauna Heater

The C2 includes a freestanding FERO electric sauna heater, with sauna stones and a heater guard. The heater provides the traditional high-heat sauna environment, and water may be added to the hot stones according to the heater manufacturer's instructions to create the characteristic humid sauna experience.

Current retailer specifications identify the heater as 9kW, with a 220–240V / 50–60Hz supply and 50A configuration.

External Digital Controls

The external digital control panel provides convenient access to the sauna's primary settings, including temperature, session duration, and backrest lighting. The control panel also features a locking cover to protect the controls when the sauna is not in use.

Heat Retention & Insulation

The cabin uses 2.1-inch mineral-wool insulation between the walls, along with rubber seals and 0.3-inch tempered glass for the door and windows. These construction details are designed to support heat retention during outdoor sauna sessions.

Aerotherm Ventilation

The integrated Aerotherm ventilation system is designed to support oxygen supply and air exchange within the sauna. This ventilation system works alongside the insulated cabin construction to create a controlled sauna environment.

• Douglas Fir exterior
• Obeche wood benches and backrest
• FERO electric sauna heater
• Sauna stones
• Heater guard

Some current dealer packages also list a thermometer, headrest, stool, and hourglass timer. Because accessory packages can vary by configuration and seller, these should be confirmed against the specific SAKSBY package before being represented as guaranteed inclusions.

Installation

The C2 is a freestanding outdoor sauna, allowing it to be positioned independently within an appropriate backyard, patio, or outdoor wellness area.

Professional installation is recommended for the larger configurations and for the electrical connection. The 9kW heater requires appropriate electrical service, and current specifications identify a 240V / 50A sauna-room configuration.

Outdoor Installation Considerations

Prepare a stable, level installation area capable of supporting the substantial weight of the selected cabin. Provide appropriate access for delivery and sufficient clearance around the structure for operation and maintenance.

The heater's electrical installation should be completed by a qualified professional according to KOHLER/FERO requirements and applicable local electrical codes.

Care & Maintenance

Regularly clean the sauna interior and allow it to dry appropriately after use. Keep the tempered glass, benches, lighting, ventilation openings, and heater area free from excessive buildup.

Inspect the exterior wood, roof membrane, seals, door hardware, and electrical components periodically, particularly in areas exposed to significant weather.

Follow the supplied KOHLER and FERO documentation for heater stones, electrical components, and ongoing maintenance.

Warranty

Current authorized-dealer listings identify a 5-year limited warranty for consumer use on the C2. Warranty coverage and conditions should be confirmed against the current KOHLER warranty documentation and the exact purchased configuration.

Safety & Usage Information

Use the sauna according to KOHLER and FERO operating instructions.

The electric heater operates at high temperature and requires proper electrical installation. Avoid touching heated components or stones during operation, and use only the amount of water recommended by the heater manufacturer when adding water to the stones.

The original draft includes claims about detoxification, circulation, immune support, and other therapeutic outcomes. Those claims have been removed from the customer-facing copy because the verified product sources establish the sauna's construction and features but do not substantiate guaranteed medical outcomes.
