Who should buy which
Buyers who want a chillered cold plunge as one purchase: a 110V plug-and-play tub with 1 year coverage on both tub and chiller.
You want sub-37°F temperatures, a 2-person tub, or premium cedar/metal aesthetics - see Renu Therapy or Morozko Forge.
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.
