Who should buy which
Buyers who want a single tub for cold and warm water, set from the unit or an app, who have room for a tub measuring 76.7 x 31.5 x 28 inches and can take a 441 lb freight delivery or pay $299.99 for Hub Group setup where it is offered.
You are buying for a gym, spa or studio, because Echelon's Terms page voids its warranties for commercial use while its support article offers 6 months; you need the 35.6°F figure confirmed, since the spec table's floor is 37°F; or you want filled weight and floor load in writing before a deck install.
Buyers who want the coldest manufacturer-rated floor available in a cedar-and-stainless tub at this price, and who can wait out a 16-week preorder.
You need delivery soon, you buy on warranty depth (Renu's 60-month tub coverage vs 12 here), or you can't run a dedicated 120V/20A circuit.
