DELIVERY & INSTALL
Delivery
Assembly
Install
The distributor price includes freight to the contiguous United States. Canada is $490. Remote or complex deliveries can fall outside those rates. The sauna ships on a wooden pallet and needs a scheduled delivery. The driver delivers curbside and lowers the shipment to the ground.
ASSEMBLY
Kohler recommends a professional installer. At least two people should do the work. Installation hardware and the installation and operation manual are included.
The C1 can sit freestanding, with only the rear wall against a room wall, or in an alcove. Leave at least 2 inches (50 mm) between the sauna and any wall, and at least 8 feet (2.4 m) of ceiling height. The floor must be level. Cement, tile, or another surface that does not absorb water is recommended unless this kit includes the floor. The floor has to support the sauna and the people using it: 58.9 lb per square foot.
The cabin arrives in sections on one or two pallets. Unpack it in a dry, level area and carry the sections to the room. Do not block the exhaust vent on the rear, or the fresh-air intake on the right-side wall near the heater. An alcove install follows the extra ventilation steps in the readiness guide, on the Documents tab.
INSTALL
A certified electrician has to finish the electrical work before assembly starts. The site needs a grounded outlet on a dedicated circuit, at the voltage and amperage for that size, and the outlet has to stay reachable after the sauna is in place. The cord is 9 feet 10 inches (2.9 m) and leaves from the top rear. In an alcove, place the outlet above the sauna, on a vertical wall, in the front third.
No plumbing is required. Site electrical, site ventilation, and finish work are not part of the kit.

Great Cold Plunge Tub
This is a great cedar-sided cold plunge tub. I spent a considerable amount of time researching cold plunge tubs and wanted one with real ceder wood to fit my sauna room. It also has a durable heat pump, compared to lower-quality chillers. I have had it a few months and no issues. Also, in the pics below, I have the chiller, which is about a 2' x 2' cube plumbed to a different space for a clean sauna room look. I would highly recommend this tub and the price is less than some on the market.

These guys are AMAZING!
These guys are AMAZING! I’d leave 10 stars if I could. We purchased a barrel sauna and cold plunge from them in fall 2025. They were absolutely terrific to work with! Our contractor and electrician had many (many) questions, all were promptly and kindly answered. They even customized our order by selling an extra long cord so we could install control panel inside for extra protection in MN winters. Shipping and delivery was a breeze. We are using our sauna daily and love it! Zero hesitation recommending this company! Thank you Johnny and Mitch for all your help!!!

What a wonderful sauna!
Researched many saunas for many months. Finally landed on this one. Only complaints i have are the instructions weren't very well written and the trim on the outside was very difficult to put together. We use it almost daily.

Great service, great sauna
Super stoked about the new sauna. I ended up with a beautiful 2-3 person cedar sauna with a huum heater. It’s perfect. These guys were helpful in choosing the right size, type, etc.
very glad I used the cold plunge guys.

Awesome!
I ordered my heater on a Thursday and it arrived the following Tuesday.
The price was by far the lowest I was able to find. I am super impressed with this company.
