I'm looking for a Toto that is shorter (non ADA) for my short wife. I installed the shorter drake in a friends house for them (14 1/2"?).I was about to order a Drake II for myself and noticed they all seem to be ADA heights-I like the dual flushing Drake II models over the rim hole standard Drakes. Any suggestions on Toto models with dual flush? a two piece would be the first choice but if its non ADA short I'd settle on a single piece. Seems most Totos are ADAs.
