How do I know if my toilet is 10 or 12 rough in?

How do I know if my toilet is 10 or 12 rough in?

If the old toilet is still there, measure from the center of the capped bolts (on the bottom) to the wall (not the baseboard). There should be 24 inches of clearance from the wall facing the bowl and 15 inches on each side as a guideline. If your measurements are between 11.5 and 12.5 inches, it is a 12-inch rough-in.

Is 12-inch rough in standard?

The standard toilet rough-in is 12 inches, but don’t assume you have a 12” rough-in without measuring! Some older homes come with 10” or 14” rough-in sizes. You may also find 10” rough-in sizes in powder rooms, half baths, or other small bathrooms to save space.

What does rough in size mean?

Start by measuring the rough-in size. This is the distance between the wall behind the toilet and the center of the drainpipe or the bolts that hold the toilet to the floor.
