Redoing a half-bath. I have the entire bathroom gutted, including the tile floor (concrete subsurface). My toilet rough in to the old wall was 16" (should be roughly the same when i replace wall). I bought a 2" offset flange, but am hesitant to install it. Anyway, I would still have to get a 14" rough in.

Any suggestions? Is the offset installation easier than I think it will be (I will have to remove some concrete. Are there 16" toilets?
