A round bowl Drake measures 26-3/8" according to the spec sheet. There may be some other possibilities as well. My suggestion is that you go to the top of this page and click on "Toilet Reviews". Then select "Shopping" and finally "Toto". This will take you to a description of the Toto models and includes the specifications for each. The usual problem people have when looking for a toilet with a short distance from the wall to the front is a door that opens into the room. One possible, albeit fairly expensive, is to replace the swinging door with a pocket door. Just something to consider.
