Aurora 300SH

SunRay's cheapest 4-seat barrel at $5,290, and the smallest 4-seat barrel we track at 61 by 72 inches.

Aurora costs $1,322 per seat, right at the barrel median of $1,326, and sits 17th of 37 barrels. It is 61 inches long, which is 11 inches shorter than the other SunRay 4-seat barrels and the smallest footprint among four-seat barrels at about 30 square feet. Heater power is 6 kW, standard for the class, and it weighs 721 pounds.

The Oasis, with a porch and 11 more inches of length, costs $500 more. The Almost Heaven Pinnacle seats four for $5,303, $13 more, and it states a Limited Lifetime warranty, which is longer than the 10 years you get here. Squeezing four adults into 61 inches will be snug, so we would treat this as a three-plus-one sauna, or a good fit for a small lot. It has no porch recorded. Only Topture lists it in our data.
