The Clayton, Dartmouth are good ADA style toilets.
Bowl wash is fairly good, in that it is even around the bowl.
I prefer them over the Promenade.
There are no 1.6 gallon toilets that are as good as the old 3.5's for bowl wash.
Toto has a dealer locator on their web site
I prefer to hand deliver toilets, breakage by shipping companies is just a fact of life.
