Our take
The Kohler C1 Indoor Sauna Kit, Graphite Grey (2-Person) is a 2-person traditional cabin for indoor use, sold by Topture for $17,157 when we last checked on 30 Oct 2026. Among 28 traditional and hybrid indoor saunas we list, its spec score ranks 17 of 28, and its price compares with a $7,947 median for the group.
Needs a dedicated 30A or 240V circuit. Budget for an electrician and, where required, a permit. Its published size leaves about 10.5 sq ft of footprint per seat.

Dimensions and installation
- Power. Needs a dedicated 30A or 240V circuit (240V, 30A · 4,500 W). Have a licensed electrician confirm your panel and wiring before you order.
- Floor space. The maker doesn't publish clearances here, so Fit Check assumes 3 in at the sides and back: plan on about 72 × 49 in of floor.
- Ceiling. At 84 in tall plus our 6 in allowance above, you'd want a ceiling of at least 90 in. Confirm with the manual.
- Doorways. The listing doesn't give the largest delivered piece, so measure your narrowest door or gate and ask the seller.
Running cost estimate
At its rated 4,500 W, four 75-minute sessions a week (warm-up included) at the U.S. average of 18.3¢ per kWh (EIA) come to about $18 a month, or $215 a year. This is an estimate, not a quote: heaters cycle off once hot, so most owners pay less. Use your own rate in the True Cost calculator.
Warranty and support
Kohler 5-year limited. source Orders, delivery and warranty claims go through Topture, the seller, and Kohler, the maker. Read the written warranty before you buy, because outdoor use and self-installation can change the terms.
