If your shower arm is rusty, leaking, or simply outdated, you may be considering replacing it with a new one. Luckily, learning how to remove a shower arm is a straightforward DIY task that doesn’t require advanced plumbing skills. With just a few basic tools and the right steps, you can remove the old arm and install a new one in less than 30 minutes.
In this guide, we’ll walk you step by step through removing a shower arm, highlight the tools you’ll need, share troubleshooting tips for stuck or corroded arms, and answer common questions so you can complete this project with confidence.
Tools and Supplies You’ll Need
- Adjustable wrench or pliers
- Soft cloth or rag (to protect finish)
- Plumber’s tape (Teflon tape)
- Penetrating oil (if the arm is stuck)
- Replacement shower arm and flange
Step-by-Step: How to Remove a Shower Arm
- Turn off the water
You don’t need to shut off the entire house water supply—just make sure the shower valve is closed. - Remove the shower head
Unscrew the shower head from the arm. Use a cloth and wrench if needed, but often it comes off by hand. - Loosen the shower arm
Wrap a cloth around the shower arm where it meets the wall to prevent scratches. Use a wrench or pliers to grip and twist counterclockwise. - Unscrew by hand
Once loosened, turn the arm by hand until it comes free from the pipe fitting inside the wall. - Remove the flange
Slide the decorative flange (escutcheon) off the pipe opening. This will expose the plumbing connection. - Inspect and clean the threads
Remove any old plumber’s tape, rust, or buildup from the threads inside the wall with a brush or rag.
Installing a New Shower Arm
- Apply Teflon tape
Wrap plumber’s tape clockwise around the threads of the new shower arm. This helps prevent leaks. - Insert the new arm
Thread the new shower arm into the pipe fitting by hand. Make sure the bend faces downward. - Hand-tighten, then wrench
Turn the arm until snug. Use a wrench for a final slight turn, but avoid overtightening, which could damage the pipe. - Slide the flange back
Push the decorative flange against the wall to cover the opening. - Reattach the shower head
Screw the shower head back onto the new arm. Apply plumber’s tape to its threads if needed. - Test for leaks
Turn on the water and check connections. If leaks appear, reapply tape and tighten slightly.
What If the Shower Arm Is Stuck?
- Use penetrating oil: Spray WD-40 or similar product around the joint, wait 10–15 minutes, then try again.
- Apply gentle heat: Use a hair dryer to warm the joint, which may loosen rusted threads.
- Double wrench method: Hold the shower arm steady with one tool while using another to apply counterpressure.
Tips to Prevent Future Problems
- Always use plumber’s tape when installing a new arm.
- Avoid overtightening—hand-tighten plus a small wrench adjustment is enough.
- Choose corrosion-resistant finishes like chrome or brushed nickel.
- Periodically check for leaks or rust around the connection.
