Resting in a mount on the shower arm, a hand-held showerhead connects to the water supply with a long hose that allows users to remove the head from the mount and hold it, directing the water flow more effectively. Hand-held heads are useful for people with disabilities or for simply personalising a shower. They are easy to remove and replace with a traditional overhead showerhead.
Unscrew the shower hose from the mount on the shower arm to disconnect the hand-held showerhead. Unscrew the mount from the shower arm, turning counterclockwise. If the mount is too tight to remove by hand, wrap it in a rag and use an adjustable wrench.
Unscrew the shower arm from the wall. Use the rag and wrench if you cannot loosen it by hand. Remove the mounting plate and any gaskets under the plate.
Select a new shower arm that is appropriate for the overhead showerhead you are installing. If the showerhead is 7 inches in diameter or less, any shower arm is appropriate. For larger heads, select an arm that angles up instead of down.
Install the new shower arm according to the manufacturer's instructions. This will usually involve screwing the shower arm into the water supply pipe until it is tight, then threading the mounting plate over the arm. Some shower arms require the mounting plate to be in position before you screw on the shower arm. Turn completely clockwise to tighten.
Wrap the threaded end of the shower arm in Teflon tape. Screw the overhead showerhead onto the end of the shower arm, over the Teflon tape.
