i repaired one like that before. they forced the WC in place and cracked the tank.
i've also seen the wall board behind the tank cut out so there was enough room.
It's nice being a G.C. that does His own plumbing. I frame everything Myself of course.
I also have the code, and trade knowledge to frame properly for closet flanges,and the rest!
I know , Many hate Me , That's why I have Big Shoulders.
Toilet rough ins are to finished wall:

Unless I need an eye exam, it looks like the center of the flange is 9-1/4" from the base and the base is probably 3/4", so a 10" rough wc should work.
Besides framing issues, occasionally a GC neglects to mention that there will be wainscoting (tile, stone, etc.) on the back wall of the toilet room (not shown on the plans). Come to set a toilet that was roughed in at 12-1/2" off the studs and and the flange is at 11" off finished wall, grrrrrrrrr!
I bet I'd rarely have a problem roughing in after you framed out.
You are correct. Rough in is to finish wall since that is the only relevant point.
The failure isn't the inspector's, it's the installer's. The inspector isn't going to check the rough in of every fixture, not knowing what is going in. Example: Duravit Happy D toilets have rough in's all across the board(including rear outlet from the same toilet), far in excess of the 10" 12" and 14" we have with many toilets. How is it the inspectors responsibility to know what toilet you are installing.
I don't mean to run you down but I think in this instance you where short sighted.
In my hundreds of projects inspectors have not once checked any one of my thousands of my rough-ins.It would be pretty obvious to all persons that I was doing my job incorrectly and would have to pay to correct.
I;m getting 3 different trade inspections on every job. I appreciate it when they know, and do their job. On the last bath addition the building Insp. signed all the trades. He admitted
He was weak on plumbing. I actually gave Him a tutorial on total fixture units ect.
And pointed out the upc didn't require the Two cleanouts installed. Drain cleaners down the road will appreciate them. See RICK , I listen to You!!
The "fix" for the situation in the picture is a simple one:
If Kohler makes a 10" rough, you all know the new ones, the tanks sit way far away from the wall. You could get by with a new 10" rough toilet and be done with it.
Then trace that tank and recess it into the wall, cut into the studs if you have to to recess the tank and allow a gap for removal of the lid. It has to be better than chopping up that wood floor or underneath it and getting into structural work, against the latter idea I just mentioned.
I'd take a camera down that pipe and see if there is any piping that is either not deburred or cut at a traverse angle that's not square to the hub it is glued in.
I would push that line of thinking harder than assuming just because the bell is pushed forward in the closet flange, considering that is the problem.
I'm thinking it's entirely something else, and an offset flange could still be used for this. I don't like them, but sometimes they are a must.
Camera that drain, you might be surprised to see a possible hang up.
Sometimes 10" rough-in toilets are junk, but if anyone has a good one they've had luck with, post it. I put in a 10" rough Mansfield and haven't heard another complaint with leaking, or clogging, given they had chronic closet flange problems before I made corrections to the situation.
When an inspector does an inspection there are hundreds of things he could look at. However, he is not there to be the expert at plumbing, he is there to keep the plumber honest. It is the plumber who is licensed not the inspector. The responsibility to do it right lies on the plumber not the inspector. I use to have inspectors sign the card at the curb all the time because they would tell me I knew more about plumbing than they ever would. I called an inspector one day to figure out permit costs to repipe the attics of 100+ units in a community. The inspector told me not to bother with permits as he wasn't going to climb through the attics anyways. Of course the same inspector booked me as the speaker for his monthly ICBO meeting as well.
I think you are on to it!
