Who should buy which
A home buyer who would rather lie back than sit upright in a plunge, fits Renu's 6'7" and 275 lb limit, and has a level floor near a drain that can carry about 1,065 lbs, a dedicated 120V, 15A outlet within 12 feet, and 2 to 4 people to move a 297 lb tank off a pallet.
You want someone to place the tank for a known fee, since delivery is curbside and Renu publishes no price for anything more; you want a real wood breath deck, because every combination on this listing is composite; or you need an ETL, UL or CSA listing in writing, which Renu does not publish for the Aurelius.
A taller or heavier home user, whom Renu puts at 6'8" or 290 lbs and up, who wants a cold only tub and has a level floor near a drain that can carry about 1,500 lbs, a 120V / 15A outlet within reach of a 9 foot cord, and helpers to move 650 lbs off a pallet.
You want hot and cold water in one tub, since Renu's FAQ lists the Siberian Pro as cold only; you plan to plunge with a partner, since the manual says single occupancy only; or you need app control settled before you buy, because Renu's pages disagree on whether this tub has Wi-Fi.
