Who should buy which

Pick the Renu Therapy Cold Stoic 3.0 if

A homeowner replacing a cold-only tub who wants 37F and 104F from one unit, already has a dedicated 120V / 15A circuit within about 12 feet, 27 inches of clearance at the large vent, and a way to move 365 lbs off a pallet.

Skip if

Delivery stops at the curb and the 365 lb tub is yours to move from there, Renu publishes no white glove or in-home placement option at any price, and changing your mind inside the 45 day window costs a 5 percent restocking fee plus shipping.

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

Skip if
