Therefore, if you have a 3-inch nipple that is too long, you need to replace it with a 2 1/2-inch nipple. If your tub spouts come with a plastic extension nipple with 2-3-inch threaded connectors, it is advisable to replace it with a one-inch nipple for it to fit vertically flush against the wall.  

Method 3: Use A Plate Trim

Usually, the offset opening for the tub spout is ½ inch from the wall, but the gap sometimes may not look good depending on individual preference.

You can also compensate for the gap if the gap is about half an inch or less by using a trim plate. Visit any building hardware supply store nearby to look for a trim plate.

To install the trim plate uninstall the tub spout and install it behind the spout to compensate for the gap.

When you are done installing, it is advisable to seal around the base of the spout and around the trim plate with caulking silicone to protect the wall against water.
