Who should buy which

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.

Pick the Renu Therapy Siberian Pro if

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.

Skip if

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.
