American Standard was easily the best choice of 3 options
American Standard clearly has the most features / benefits amongst its competitors. Howsomever, all 3 consultants from 3 different firms spent far too much time criticizing their competition (amateurish!), oft with inaccuracies. Also all 3 consultants failed to alert me that the tub does not contain a heater, but only an in line thermostat incapable of doing no more than maintaining the temperature of the final supplied H2O, & loses even that ability if air jets are turned on. American standard Rep & their contracted install Consultant also insisted that my 40 gal H2O heater was sufficient to fill the tub with Hot H2O. In fact, it was NOT, & I ultimately replaced it with an in line, on demand 2.7 Kw tankless Electric Hot H2O heater ($1600) to acquire my desired Hot H2O temperature. All 3 firms required their Reps to attempt a 1-call close (amateurish !) , but only the American Standard Rep spent the extra time, energy, superb listening skills & aggressive working of his firms parameters to structure a package, with his firms best possible price & financing, that met my purchasing needs. The other 2 Reps either gave up, or attempted to foolishly offer a much lower price at a later date (amateurish !), after learning I had chosen American Standard.
