Kohler K-3386 Rialto One-Piece Toilet, comments and pictures
Kohler makes one of the shortest toilets in a round front. If you have a bathroom with a door that swings in, that may be something to consider.
Here are a few pictures of the Kohler Rialto
I'm not a big fan of this trapway, it's too easy to clog it.
Looking inside the tank.
Working on the fill valve.
I might add though, that it's not a great performer. There is better product out there.
I don't like the tight bends at the bottom of the trapway.
