Four of the seven platforms in this study named American Standard during the ranking stage, and it finished with an average listed rank of 2.0 and a best rank of 1. The strongest reason to consider it is the patented Quick Drain® system, which American Standard advertises as emptying the tub in less than two minutes without additional plumbing .
