Will 11 1/2" from sheetrock work for toilet rough in?

[Kail]

I am trying to build a house and am doing the plumbing myself. I roughed in my toilet flange into my first floor slab at 13" off of what should have been the outside edge of the studs. I just noticed today that the framers have framed in the wall behind the toilet further out then I expected and there is only 12" from the stud face to the center of the toilet flange. When 1/2" sheetrock is installed this will only leave 11 1/2" from the finished wall to the center of the flange. Is this enough? I am catching this a little late and the wall can't be moved at this point.

Most toilets will work, but you must verify the one you eventually select. Toilet typically have a gap behind them when the rough-in is perfect, and, even the spec sheets are for a 'nominal' value, and a toilet can vary slightly from one to the next.
