I am in the latter stages of building my own house. I will soon be installing commodes in the bathrooms. I hired a local plumber to do the rough-in for me. On checking some dimensions recently, I found that the centerline of the 4-inch sewer line is falling at about twelve-and-a-quarter inches from the face of the sheetrock in one bath, and is falling at eleven and seven sixteenths inches from the face of the sheetrock in the other bath on the opposite side of the plumbing wall. I know a standard commode roughs in at twelve inches from the finished wall to the center of the floor flange, so I am concerned that the room having the smaller dimension may be a problem. Is it? Or can a standard commode be set O.K. on a flange only 11 7/16″ from the wall. If a problem, what are my options? I understand that there are commodes available with less than standard rough-in dimensions, but don’t know how easily available they are, or how expensive. Any input, suggestions, or ideas would be appreciated.

There are lots of toilets made for 10" rough ins, I dunno about commodes.
It's probably a go............
You can get an offset flange just in case though.

11-7/16" is probably a bit tight. The commode will fit but very likely the lid won't go on all the way flat. Of course, there's probably 1/4" wiggle room in the flange mounting, so that might do it. If not, get the plumber to install a 1/2" offset flange.
