Our take
The SunRay Cayenne 4-Person Outdoor Infrared (400D3) is a 4-person infrared cabin for outdoor use, sold by SaunaKits for $4,290 when we last checked on 30 Oct 2026. Among 6 infrared outdoor saunas we list, its spec score ranks 5 of 6, and its price compares with a $4,290 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 7.1 sq ft of footprint per seat.

Dimensions and installation
- Power. Needs a dedicated 30A or 240V circuit (240V, 30A · 2,400 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 85 × 55 in of floor.
- Base. Outdoor saunas need a level, solid base such as a concrete pad or pavers, and outdoor-rated wiring. See our installation cost guide.
- 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 2,400 W, four 45-minute sessions a week (warm-up included) at the U.S. average of 18.3¢ per kWh (EIA) come to about $6 a month, or $69 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 on the cabin and heaters. source Orders, delivery and warranty claims go through SaunaKits, the seller, and SunRay, the maker. Read the written warranty before you buy, because outdoor use and self-installation can change the terms.
