Hi Lou...
I need to know the measurement from the
finished wall to the
center of the toilet bolts (or the center of the closet flange).
If 12" to 14" (or more) then you can move the toilet back anywhere between 1.5" to 2" depending on which
PVC offset flange you can get your hands on...see image.
If 14" from finished wall to the center of the toilet bolts then you are in ideal position to move the toilet back easily and end up purchasing any common 12" rough in toilet that you want (regular prices prevail).
If 12" from finished wall to center of toilet bolts then you could offset back no problem but then you would need a 10" rough in toilet and that is usually special order and costs extra money, for sure..
If 10" or less then you are stuck with what you have as they only make one or two 8" rough in toilets and they are just priced ridiculously!!...
Let us know if you have more questions on this...
