Was told by a plumber that we have toilets that are 11" rough in. My understanding is that 12" is standard. Put in a 12" toilet and it BARELY fit. Another 1/4 inch and it would not, so I'm a little leary of trying it again for the second toilet. I can't find a toilet for an 11" roughin at Lowe's. Can get a 10". Is that what is normally done?
BTW, we are replacing these because our old ones are so stained by well water that they just won't clean anymore. We have a great filter now, so we want to put in new ones just to have a much better appearance.
