Toilets, Sinks, Showers, Tubs and Disposals - Rough in spacing for toilet?

I'm remodeling my 1/2 bath and gutted the entire room. With my drywall, the center of the toilet flange will be about 11.5 inches from the finished wall. I read that new toilets are need a 12-inch rough. I have no wiggle room either, the flange drains into a 3 inch copper pipe that under the subfloor is attached to a 2 inch vent pipe that runs up th wall behind the toilet.

I read you can buy an offset flange for older home where the center was 10 or 14 inches from the finishyed wall but that doesn't seem like a viable option for only a half inch.

Should I contact the toilet manufacturer to see if my toilet will fit?

Any suggestions?

It appears you're only 1/2" short and that may not matter much. My newly constructed house using Kohler toilets has about an 1" or so from the rear of the tank. 11 1/2" may work. I'd try a dry run of setting the toilet and see what you get!

Good luck

Thanks. I found an installation file that shows 1-inch +/- 1/4 inch for the tank to the wall with a 12-inch rough. So I guess that leaves me at worst a half into to play with. Should be OK.

Thanks again.
