Step 2 · Remove the Old Shower Arm and Showerhead
Protect your drain by covering it to prevent losing small parts. Apply penetrating oil to the shower arm threads to loosen any mineral deposits or corrosion. Let it sit for 10-15 minutes. Then, using an adjustable wrench (wrapped in cloth to avoid scratches), carefully unscrew the showerhead counterclockwise. Next, remove the old shower arm, also turning counterclockwise. A strap wrench can provide extra leverage if needed.
