A tub shower diverter valve diverts water from either the tub spout to the shower or the other way around. The two main types are the tub spout diverter and handle diverter.The tub spout diverter works when you pull up a knob on the spout. The handle diverter is located somewhere between the spout and the shower head. As you rotate the handle, it diverts the water to the proper outlet. Replacing a tub spout diverter is easier than replacing the handle type, but even the handle type can be changed by someone with no experience.

Remove the tub spout type by rotating the spout counterclockwise and unscrew it from the spout pipe.
Examine the diverter handle. Use the edge of a flat-bladed screwdriver to pop off the diverter handle screw cover. Remove the handle screw with a Phillips screwdriver. Pull the faucet handle straight off. Loosen the stem screw with an adjustable wrench. Pull out the diverter valve stem.
Take the spout or diverter valve stem to your local hardware or plumbing store. Use old parts as a guide to get the proper size replacement.
Screw the tub spout back onto the pipe. For the handle type, apply pipe thread compound to the threads on the valve and screw into the socket. Tighten with the wrench. Slip on the diverter handle. Insert the handle screw and tighten. Press the screw cap back into place.
Run the tub and shower. Check for proper operation.
