Our take
The SunRay Cayman 400D7 Outdoor 4-Person is a 4-person traditional cabin for outdoor use, sold by Topture for $5,690 when we last checked on 31 Oct 2026. Among 56 traditional and hybrid outdoor saunas we list, its spec score ranks 8 of 56, and its price compares with a $8,180 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 8.6 sq ft of footprint per seat.
Strengths
- Priced well for its specs: $5,690 against a $8,180 median for traditional and hybrid outdoor saunas
- Roomy: about 8.6 sq ft of footprint per seat
Trade-offs
- Needs a dedicated 240V or 30A circuit, installed by a licensed electrician
- Wattage not published, so running cost can't be estimated
Good fit for
- Households of up to 4 at a time
- Backyards with a level, solid base and outdoor-rated power nearby
- People who want hot, steamy sessions: up to 180 °F with water on the stones
Consider another option if you're
- Homes with no room in the panel for a new 240V circuit
- Anyone who wants a plug-in setup or gentler air heat: look at infrared models
- Anyone planning an indoor install: it's built for outdoors

Dimensions and installation
- Power. Needs a dedicated 30A or 240V circuit (240V, 40A · watts not published). 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 × 72 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.
Warranty and support
SunRay lists 7 years structural in its warranty terms (some pages say 10; 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.
