Our take
The SunRay Charleston 400TN Indoor 4-Person is a 4-person traditional cabin for indoor use, sold by Topture for $4,598 when we last checked on 30 Oct 2026. Among 28 traditional and hybrid indoor saunas we list, its spec score ranks 12 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 7.8 sq ft of footprint per seat.
Strengths
- Priced well for its specs: $4,598 against a $7,947 median for traditional and hybrid indoor saunas

Trade-offs
- Needs a dedicated 240V or 30A circuit, installed by a licensed electrician
Good fit for

Consider another option if you're

Dimensions and installation
- Power. Needs a dedicated 30A or 240V circuit (240V, 30A · 6,000 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 77 × 66 in of floor.
- Ceiling. At 80 in tall plus our 6 in allowance above, you'd want a ceiling of at least 86 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 6,000 W, four 75-minute sessions a week (warm-up included) at the U.S. average of 18.3¢ per kWh (EIA) come to about $24 a month, or $286 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
SunRay lists 7 years structural in its warranty terms (10 elsewhere on the page; we use the lower figure) and 1 year on parts and electronics. source Orders, delivery and warranty claims go through Topture, the seller, and SunRay, the maker. Read the written warranty before you buy, because outdoor use and self-installation can change the terms.
