How to Replace a Shower Head Arm (And Shower Head)
Learning how to replace a shower head arm (and the shower head) is pretty easy for any homeowner. I’m going to walk you through the basic steps.
Also included below is a tutorial video that will show you how to replace the arm, head, and even the shower valve. The valve, unlike the arm and head, is a complicated project. But the video below will show you what’s included in the entire replacement process.
What Will You Need?
We recommend you begin by removing the shower head and taking it to a hardware store or plumbing supply center. You’ll also need these tools:
- New shower head
- New shower arm
- Adjustable wrench
- Slip-joint pliers
- Masking tape
- Old rag
- Lubricating spray (WD-40)
- Teflon tape (also called plumber’s tape)
How to Replace a Shower Arm and Shower Head
Now that you have gathered all your tools and parts, here’s what you need to do.
Step 1: Removing an Old Shower Head
You might be able to unscrew the shower head from the arm without your pliers or wrench. So, try unscrewing by hand first. If that’s not possible, attach the pliers to the top of the shower arm to keep it from rotating. Then position the adjustable wrench on the collar nut and turn it clockwise. If it’s still difficult, apply your WD-40. In about 30 seconds, you should have no problem removing the shower head.
Step 2: Removing an Old Shower Arm
Place both hands on the shower arm and turn it counterclockwise. If it doesn’t loosen from the wall, apply your WD-40 lubricating spray to the base of the arm). The shower arm is threaded into a water supply pipe behind the wall, so spray your lubricant into that area. Try twisting it again or use an adjustable wrench to get better leverage.
PRO TIP
If you’re replacing your shower head and shower arm, you might as well not separate them. Just remove the arm (with the shower head attached). Then take the entire assembly to your preferred store for a replacement.
Step 3: Installing a New Shower Arm
Before starting, wrap the head of the adjustable wrench with masking tape to prevent any scratches to your new arm piece. Next, wrap 3 to 5 layers of Teflon tape around the threads at both ends of the shower arm. Do this in a counterclockwise direction. Here’s how to properly wrap Teflon tape.
Insert the arm into the connection in the wall and twist clockwise. Once it’s hand-tightened, use the adjustable wrench (with masking tape around the jaws or an old rag around the arm) to tighten it as much as possible.
Step 4: Installing a New Shower Head
Insert the new shower head onto the arm and twist it clockwise. Again, use the adjustable wrench (with masking tape around the jaws or an old rag around the shower head collar nut) and tighten.
Step 5: Test for Leaks
Turn on the shower and watch for leaks at the two arm connections, including the collar nut if there is one. If there are any leaks, retighten the arm or head with your wrench. If you still have a leak, it might be that you’ve incorrectly wrapped the plumber’s tape on the threads. In that case, you’ll have to redo that part of the process.

The video below shows a much more complicated plumbing problem: the replacement of the shower valve. The shower arm and head are replaced as well in that process.
Final Thoughts
In conclusion, if you simply need a shower arm or shower head replaced, the process is fast and easy. On the other hand, a shower valve is a different story.
The former is a DIY project any homeowner can take on. The latter is a project meant for a skilled, licensed plumber who has experience with soldering, pipe measuring, and pipe cutting.
