Who should buy which

Pick the Renu Therapy Aurelius if

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.

Skip if

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.

Pick the Renu Therapy Cold Stoic 2.0 if

Premium-aesthetics buyers who want the longest warranty in the category and a tub that reads as architecture.

Skip if

You're budget-constrained, want apartment-friendly install, or don't care about premium materials.
