I am installing a new toilet in a very old bathroom. There is exactly 11" from the wall to the exact center of the outlet. The outlet itself is 4" in diameter, so 12" from the wall is still over the opening.

My question is: Can I use a toilet with a 12" rough-in distance for this situation. I'm considering the American Standard cadet 3. I know that I could get a 10" rough-in toilet, but those seem hard to find and more expensive.

Many thanks for your help.
