Our take
The SunRay Roslyn 4-Person Infrared (HL400KS) is a 4-person infrared cabin for indoor use, sold by Topture for $4,298 when we last checked on 31 Oct 2026. Among 50 infrared indoor saunas we list, its spec score ranks 45 of 50, and its price compares with a $3,098 median for the group.
Needs a dedicated 120V circuit. Budget for an electrician and, where required, a permit. Its published size leaves about 6.8 sq ft of footprint per seat.

Dimensions and installation
- Power. Needs a dedicated 120V circuit (120V, 20A · 2,100 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 78 × 57 in of floor.
- Ceiling. At 76 in tall plus our 6 in allowance above, you'd want a ceiling of at least 82 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 2,100 W, four 45-minute sessions a week (warm-up included) at the U.S. average of 18.3¢ per kWh (EIA) come to about $5 a month, or $60 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 and 1 year on parts and electronics (parts only, labor not covered). 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.
