CL7G 6-Person Outdoor Cube Sauna

A 6-seat cube at $7,990 with a 5-year warranty, the cheapest cube per seat at $1,332, though no heater power is stated.

The CL7G earns its place with price and coverage together. At $1,332 per seat it is 16 percent under the cube median, and it is the only SaunaLife cube here with a stated warranty (5 years). The shell is 86.6 by 91 inches and 93 tall, 1,875 pounds. The Dundalk cabin Georgian with porch is $8,563 for the same six seats, and the Almost Heaven Seneca barrel costs less at $6,191 but stands only 85.9 inches tall.

A caveat: SaunaLife gives no heater rating, which matters on a 6-seat sauna where the usual figure runs 8 kW. Ask whether a heater is included and how strong it is. Pick the CL7G if you want a square, upright six-seater and a warranty you can quote. Topture and Recovery for Athletes both list it at $7,990.
