Offset for 11.5" rough-in iron drain
We have a 1945 home and the rough-in is 11.5". We purchased a 12" toilet being told there was some leeway. However, there was none. We don't want to purchase another toilet and not be able to use it.
While we (my husband and I) didn't quite understand it, we were left with the impression that there was nothing to be done but to install a 10" rough-in toilet thereby having a 1.5" gap behind the toilet. I'm not crazy about that idea. I did find a few toilets that would work with an 11.5" rough-in, but they were all too large for the minuscule bathroom.
The drain pipe is iron and a scant over 11.5" from the finished wall, not including the base board and is about 3.5" diameter.

We don't have much room to work with and one thing we can not do is tear up the floor. We probably can enlarge the area around the drain somewhat, but that's all. Because this bathroom is in the attic, under the eave and next to the garage crawl space, changing any plumbing would require not only removing the floor in the bathroom, but also the floor underneath it which is the ceiling of the bathroom underneath. That area used to be a shower and it has cement that would have to be removed. Then the pipes run into the garage crawl space, which would require removing part of the roof to get to them ... so, we need to find a solution that doesn't involve tearing up our entire home and even if we were willing to do it, couldn't possibly afford it.

Note: I saw a similar post in this forum, but failed to understand how that person resolved it.
Can we use an offset flange?
What kind?
How do know what size to select?
What would we need to do to install it?
Anything else we need to know?
