For toilet instalation, how much lee way is available for the centre of the waste pipe from the wall. I am one quarter inch short of 10". Do I have to go for an offset flange for this little bit. Thanks.
A standard toilet is made to rough-in at 12" from the wall & won't work here. A 10" rough-in is available, but often in limited styles. If you're not too picky about styles, any one of these will probably fit.
Do not forget if you are doing new work to add for the dry wall in your finish measurement
