The rough-in is the distance from the back of the toilet flange to the wall. To measure the rough-in, measure from the center of the two bolts on the back of the toilet flange to the wall.

The rough-in is typically 12 inches, but it can vary depending on the model of toilet. If you’re not sure what the rough-in is on your toilet, you can check the toilet’s installation instructions or contact the manufacturer.
