But adding a regular shower to an existing tub enclosure is a major undertaking. One easy solution is to install a special tub diverter spout that allows you to hook up a handheld shower to a bathtub faucet with only a minor plumbing change. Once the spout is in place, you can choose from a wide variety of handheld showers, put up a shower curtain and enjoy the relaxing spray. Look for a slot or hole in the bottom of the spout that gives access to a set-screw. Remove the set-screw using an Allen wrench or screwdriver, then pull the spout off the wall pipe. Alternatively, remove a threaded spout by wrapping a soft cloth around the end and grasping the spout with a pair of adjustable pliers.
