- Clean soft cloth
- Plumber’s tape
- Shower arm
- Flange (often comes with shower arm)
Turn off the water supply to the shower. If you’re keeping the shower arm, wrap a cloth or plumber’s tape around both ends of the arm to protect it from scratches. Grip the shower arm with pliers while using a wrench to turn the nut counterclockwise.
Unscrew the showerhead. Remove the screw holding the flange in place, then remove the flange. Unscrew the shower arm using pliers at the base.
If the showerhead is stuck, soak the cloth in white vinegar, wrap it around the nut on the showerhead, and let it sit for a few minutes to loosen mineral deposits.
Wipe around the hole in the wall to remove grime. Tightly wrap five layers of plumber’s tape clockwise around the end of the shower arm that goes into the wall. It’s important to wrap the tape in the opposite direction of how the arm will twist into place.
Attach the end of shower arm into the pipe in the wall, turning clockwise. (Because you wrapped the tape clockwise in Step 3 as well, it’s now turning counterclockwise, making a tight bond.) Replace the flange. Wrap three layers of tape around the exposed end of the shower arm.
Screw the showerhead into place by hand. Protect the showerhead joint with a cloth or tape and then tighten with a wrench, turning clockwise, to prevent leaks and water-pressure issues.
