I can't talk my husband into buying the Toto Ultimate MS854114-01 . He found a different one piece elongated on Amazon for less money and keeps asking me what's wrong with it? I can't find any reviews of it other than those of customers at Build.com. The difference in price between this American Standard Fairfield 2862.056.020 that he likes the price of and the Toto Ultimate is $125. The Toto Ultimate is $377 and the American Standard Fairfield is $248. Both are one piece elongated toilets incl a soft close seat. All I can find about the flush is that the Fairfield has a siphon action bowl, a high volume 3" flush valve and a pilot fill valve vs the Power Gravity of the Toto. Both are 1.6 gal.
