KOHLER C1 Indoor Sauna in Scandinavian Spruce
The KOHLER C1 pairs Scandinavian spruce walls with obeche seating, a FERO electric heater, indirect lighting, and external digital controls. Choose a two-, three-, or five-person configuration for your indoor wellness room.
Freestanding and alcove installations are supported when the room meets Kohler’s clearance, ventilation, floor, and electrical requirements. Select the size and floor option that fit your room before arranging assembly or electrical work.
A Coordinated Indoor Sauna System
C1 brings the sauna cabin, heater, controls, seating, and lighting together in one package. The natural spruce finish can coordinate with a home gym, bathroom suite, or dedicated relaxation room.
Capacity is a starting point for comparison. Consider how people will sit, available bench room, access around the cabin, and the installation space required above and beside the sauna.
Features That Shape the Sauna Experience
Scandinavian Spruce Finish
Matching interior and exterior wall finishes provide a consistent natural-wood appearance. Plan the surrounding room finishes and care routine around an indoor sauna environment.
Obeche Seating
The seating package includes a bench, backrest, headrest, and stool. Compare the layout of each size with the seating positions you intend to use.
FERO Electric Heater
The included heater is matched to the cabin size. Review the electrical comparison below with your licensed electrician before preparing the circuit.
Lighting and Digital Controls
Warm 2700K indirect lighting and an exterior control panel provide convenient access to temperature, time, and backrest lighting settings.
Insulated Cabin Construction
Mineral wool insulation, tempered glass, and door seals form part of the cabin system. Follow the assembly directions so the panels and seals fit as intended.
Aerotherm Ventilation
The ventilation system is part of the cabin design. Keep its air paths clear and coordinate any alcove or exhaust arrangement with the model-specific instructions.
Choose Your Size and Floor Configuration
| Size | Listed capacity | Without floor | With floor |
|---|---|---|---|
| Small | Up to 2 people | K-38440-0FNC-SPS | K-38440-1FNC-SPS |
| Medium | Up to 3 people | K-38441-0FNC-SPS | K-38441-1FNC-SPS |
| Large | Up to 5 people | K-39166-0FNC-SPS | K-39166-1FNC-SPS |
Select the intended variant using the product’s purchase options. Confirm installation-service availability and scope separately for your location.
With Floor or Without Floor?
Without-Floor Configuration
The sauna uses the prepared room surface beneath it. Your installer should verify that the surface is level, load-bearing, easy to clean, and suitable for the manufacturer’s installation requirements.
Review floor materials and moisture management before choosing this option.
With-Floor Configuration
This configuration includes the sauna floor option. Confirm its dimensions, finished height, entry transition, and supporting-surface requirements using the matching specification sheet.
A supplied floor still requires appropriate room preparation and structural support.

Have a licensed electrician confirm the matching documentation, supplied connection, circuit protection, wiring, and local requirements for the exact unit ordered. Electrical preparation and final connection must be included in your project plan.
Dimensions and Weight: No-Floor Models
| Measurement | Small | Medium | Large |
|---|---|---|---|
| Overall drawing dimensions, W × D × H | Approx. 65.8 × 46.1 × 83.5 in. | Approx. 77.6 × 54.0 × 83.4 in. | Approx. 81.6 × 77.6 × 83.5 in. |

These figures apply to the referenced no-floor models. Use the full dimensioned drawing for construction, including door movement, projections, and required clearances. Obtain the matching with-floor sheet when selecting that configuration.
Prepare the Room Before Delivery
The cabin footprint is one part of the installation area. Plan space for assembly, room ventilation, service access, and comfortable entry and exit.
Ceiling and Wall Clearance
The supplied Small-model assembly manual calls for an 8-foot minimum room ceiling and at least 2 inches between the cabin and room walls. Confirm the matching requirements for your selected size and layout.
Supporting Floor
Have the supporting structure assessed for the cabin, heater, and occupants. Use the selected configuration’s technical information when evaluating an upper floor or an existing room.
Alcove and Ventilation
Keep air paths and roof-mounted equipment accessible. An alcove must preserve ventilation and service access; coordinate any exhaust extensions with the installation instructions.
Delivery and Assembly Access
Measure doorways, hallways, stairs, and turns for packaged panels and glass. Arrange a dry staging area, suitable lifting assistance, and an experienced assembly team.
What Is Included?
The manufacturer describes a coordinated cabin package. Confirm the item list for your selected size and floor configuration in the order documentation.
- Scandinavian Spruce cabin panels, ceiling components, frame, and assembly hardware
- FERO heater, sauna stones, and protective heater railing
- Seating components, backrest, headrest, and stool

Confirm any decorative roof kit, site work, electrical work, delivery upgrades, or professional assembly service separately. A sauna-only purchase does not establish the scope of an installation package.
Freight Delivery, Assembly, and Returns
Plan for scheduled freight receiving and confirm unloading access, pallet dimensions, and where the shipment will be placed. Review any stairs, restricted truck access, or special receiving requirements with our team before ordering.
If an installation option is selected, obtain its written scope and site-readiness requirements. Confirm responsibility for assembly, electrical preparation and connection, room modifications, and packaging disposal.
Review the shipping charge and delivery estimate for your selected variant, along with our shipping policy and return policy. Contact us before requesting a return or arranging freight.

KOHLER C1 Scandinavian Spruce FAQs
Does the sauna include a heater and stones?
Yes. The cabin package includes a FERO heater and stones. Heater output depends on the selected size; review the electrical comparison and matching technical sheet.
Can I use the C1 outdoors?
The C1 is designed for indoor installation. For an outdoor location, compare the KOHLER C2 outdoor sauna.
Can it fit in an alcove?
Alcove installation is supported when the matching instructions are followed. Preserve the required airflow, clearances, door access, and access to roof-mounted equipment.
Does a with-floor model eliminate room preparation?
The supporting surface, structural capacity, ventilation, and electrical supply must still meet the requirements for the selected configuration. Confirm the floor system with your installer.
Is professional installation available?
Check the purchase options and contact us to confirm service availability for your location. Review the scope and required site preparation before booking an installer.
Which measurements should my builder use?
Use the current dimensioned drawings for the exact model, floor configuration, and accessories. Include installation clearance and service access rather than relying on a rounded footprint alone.
