I have a toilet (unnamed but with a UPC stamp) and I'm not sure how to measure the rough in. When I measure from the wall to the centre of the bolts I get 11 1/4 inch. I don't know whether the bolts are always aligned with the center of the drain or not. The wall is ceramic so I'm not sure whether it's shortening the actual rough in length or not. If my measurement is correct, will a toto 12 inch rough in toilet fit?
