Kohler Saunas: C1 Indoor and C2 Outdoor Sauna Kits
The Kohler sauna collection offers two options for different installation settings. The C1 is designed for indoor spaces such as spare rooms, basements and home gyms. The C2 is built for outdoor placement on a deck, patio or backyard pad. Both models feature Scandinavian Spruce interior walls, obeche benches and the Kohler FERO electric heater.
The main difference is where you plan to install the sauna and how much room you need. Compare the sizes, finishes, floor options and electrical requirements before choosing a model.
| Feature | Kohler C1 Indoor Sauna | Kohler C2 Outdoor Sauna |
|---|---|---|
| Sizes | 2, 3 or 5 person | 3, 5 or 6 person |
| Exterior finishes | Scandinavian Spruce or Graphite Grey | Douglas Fir or Weathered Grey Spruce |
| Interior | Scandinavian Spruce walls and obeche benches | Scandinavian Spruce walls and obeche benches |
| Floor | Full floor or no floor | Integral floor |
| Heater | FERO 4.5 kW for 2- and 3-person models; 9.0 kW for 5-person model | FERO 9.0 kW |
| Electrical supply | Dedicated 240V circuit, 30A or 50A depending on size | Dedicated 240V, 50A circuit |
| Roof | Optional roof kit conceals the control box | Insulated waterproof roof with dual-pane glass |
Location decides the model. Head count decides the size.
Explore our indoor saunas and outdoor saunas to compare installation options.
Kohler's sauna range also draws on its relationship with German sauna manufacturer Klafs. The C1 and C2 bring together Kohler's product design and sauna construction features with the FERO heater included in each kit.
Why Choose Kohler Saunas
Kohler saunas include several construction and control features that help buyers compare specifications before choosing a model.
- Mineral wool insulation: A 2-1/8-inch (54 mm) layer of mineral wool sits between the walls.
- Tempered glass: The door and windows use 5/16-inch (8 mm) tempered glass.
- FERO electric heater: Each kit includes the Kohler FERO heater, stones and an obeche wood heater guard.
- Digital controls: Dual thermostatic control and an external digital panel manage temperature, time and backrest lighting.
- Ventilation and lighting: The design includes an Aerotherm ventilation system and 2700K warm white indirect lighting.
These features give buyers specific construction details to compare when evaluating a Kohler sauna for their home.
Kohler C1 Indoor Sauna Kits
The Kohler C1 indoor sauna fits spaces such as a spare room, basement, home gym or bathroom alcove. Kohler lists both freestanding and alcove installation options. The C1 comes in three sizes and two exterior finishes, with full-floor and no-floor configurations available.
C1 Sizes and Finishes
The C1 is available in 2-, 3- and 5-person configurations.
- Scandinavian Spruce: A light wood finish suited to interiors with a traditional wood look.
- Graphite Grey: A darker exterior option for contemporary interiors.
Compare the available C1 models to find the size and finish that fit your room and preferred design.
C1 Full Floor and No Floor Options
The C1 offers two floor configurations. The no-floor version sits directly on a finished tile surface or slab and reduces the step-in height. The full-floor version creates a self-contained base and can suit spaces with unfinished or uneven surfaces.
The full-floor option typically costs more than a comparable configuration without a floor, with the price difference depending on the sauna size and model. Check current product pricing before choosing.
C1 Heater and Electrical Requirements
The 2- and 3-person C1 models are listed with a 4.5 kW FERO heater, while the 5-person model uses a 9.0 kW heater. Electrical requirements vary by size, with a dedicated 240V circuit specified. The optional C1 roof kit conceals the control box for a cleaner installation.
Check the electrical specifications for your chosen model and consult a licensed electrician before installation.
Kohler C2 Outdoor Sauna Kits
The Kohler C2 is designed for outdoor placement on a deck, patio or backyard pad. Available in 3-, 5- and 6-person sizes, this Kohler outdoor sauna gives homeowners options for different outdoor spaces. Its integral floor and weather-ready construction distinguish it from the indoor C1.
C2 Sizes and Finishes
The C2 comes in three sizes: 3, 5 and 6 person. Buyers can choose between two exterior finishes.
- Douglas Fir: A warm wood exterior that weathers over time.
- Weathered Grey Spruce: A grey, weathered appearance from the start.
Check the dimensions of each model against your available outdoor space before ordering.
C2 Built for Year-Round Outdoor Use
The C2 features a triple-insulated waterproof ceiling, dual-pane glass, a lockable door and a lockable control cover. Its weather-ready exterior is designed for permanent outdoor placement. These construction details make the C2 a suitable option for buyers looking for a Kohler outdoor sauna that can remain outside throughout the year.
C2 Heater and Electrical Requirements
The C2 is specified with a Kohler FERO 9.0 kW electric heater and a dedicated 240V, 50A circuit. Electrical readiness should be confirmed before installation. Consult the product documentation and a licensed electrician to verify the requirements at your installation site.
Kohler Saunas by Size: 2 to 6 Person
The right size depends on how many people will use the sauna and the space available for installation.
- 2 person: The C1 is the smallest option for indoor installation.
- 3 person: Choose between the indoor C1 and outdoor C2.
- 5 person: Both the C1 and C2 offer this capacity.
- 6 person: The C2 is the available option for outdoor installation.
Before ordering, compare the exterior dimensions of the selected model with the available floor space. Allow for the installation and electrical requirements specified by Kohler.
