The 412MF's base is 10" wide. 1/2 of that means that it spreads 5" to either side of the toilet centerline. The back of the toilet base is somewhere about 4.5"-ish (maybe a smidge more) from the FINISHED wall (NOT the baseboard). So...if your pipe is sufficiently to the left of the toilet OR emerges sufficiently-close to the wall, it will work. You can always pull or cut the escutcheon if that's the deciding factor as opposed to the pipe. Good luck and come back if you have other questions! You will love that toilet.
