When it comes to removing a shower handle, the first step is to locate the access panel. This panel is usually located behind the shower handle and can be removed with a screwdriver. Once you have access to the valve, turn off the water supply by shutting off the valve located near the outdoor faucet too low to the ground. This will prevent any water from spilling out during the removal process. Next, use a wrench to loosen the nut that holds the handle onto the valve stem. Once the nut is loose, you should be able to lift the handle off the stem and remove it completely.
