I don't know about the Rialto but I can tell you (After installing my first Toto three weeks ago) that you have never seen anything like a Toto! In fact I order two more for the rest of the bath rooms. You flush it and it's gone! Have yet to ever flush a second time. Their Sanagloss finish is great.

: I would like to have a small (Low tank, round bowl) one piece toilet for our small bathroom. We installed a Kholer Rialto and am getting frequent clogs. The plumber said that the Rialto is not a good toilet b/c it has very little flush power and that a Toto would be much better. Any thoughts? Thanks.
