: Based on your recommendations, I would very much like to install a new Toto Ultramax toilet; however, the rough-in measurement in my bathroom is 11-1/4". Do you think that I could still fit in the Ultramax, which has a 12" rough-in? (The tank on my old existing toilet is right up against the back tile wall). Thank you.

11-1/4" works fine with the Ultramax.
