How do you replace a shower spigot?

To replace a shower spigot, first, turn off the water supply to avoid leaks. Remove the old spigot by unscrewing it from the wall, which may require a wrench or pliers if it's tight. Clean the area and apply plumber’s tape to the threads of the new spigot before screwing it in place. Finally, turn the water supply back on and check for any leaks.
