What is a Shower Arm?

Before we help you with the shower arm installation tips, let us throw some light on what actually a shower arm is!

A shower arm is a cylindrical pipe fitting that connects your shower head with the water supply.

The arm can be of any size and shape based on the brand you are using! Shower arms are prone to corrosion as they are in direct contact with the water, so it is better to replace them at the earliest before the problem escalates into a more significant issue.

Step-by-step Process on How to Install a Wall Mounted Shower Arm

Step 1: Find the Female Fitting

You should start the process by finding the female fitting. In order to find the female fitting, you need to locate the tub valve. Generally, the tub valve is located above the bathtub faucet just behind the wall.

Have you located the valve? Great! You will now be able to see a vertical water supply that runs through the wall. After the accomplishment of these steps, you should find an ideal spot where you want to attach the shower arm.

Mark the spot with a pencil so that it becomes easier for you to judge whether the spot is perfect or not! Now it is time to cut a hole through the drywall so that you can access the vertical supply line.

You will see a female fitting attached to the pipe, and that is what you need to install the new shower arm. While using the saw on the drywall, be extra cautious, and prevent the pipes from getting damaged.

Step 2: Secure the Shower Arm Using Plumbing Tape

After making a hole in the drywall and after finding the female fitting, it is time to secure the shower arm. You can use a little bit of plumbing tape on both ends of the shower arm to make sure that it establishes a leak-proof connection with the water supply line and with the showerhead.

Also, plumbing tape will help you in securing the shower arm right in its place with the assurance that there will be no chances of leakage in the future.

Step 3: Attach the Shower Arm with the Female Fitting

This is the most crucial step of this procedure, and the whole assembly of the arm will depend on this step. So it would be best if you prepare yourself for it by taking a long breath.

Start with inserting the shower arm through the hole in the drywall. You have to connect the shower arm to the female fitting in order to make it work. Once you have attached the shower arm with the female fitting, make sure to tighten the connection as much as possible.

Now take out the wrench and tighten the connection to ensure that it is done correctly! We would suggest you use a rug or a piece of cloth before putting the wrench on the shower arm. It will help you in preventing any scratches on the shiny shower arm.

Step 4: Mount the Shower Head with the Arm

Mounting the showerhead with the arm is a straightforward part, and you can do it on the go! To ensure that the showerhead is attached correctly, you should move it a little bit to check whether the showerhead is stable in different positions.

Step 5: Check the Installation Again

Before you run the water supply to test the newly installed shower arm, I would recommend you to recheck the installation. Check all the connections and make sure that the shower arm is attached correctly with the female fitting.

After checking all the connections, you can replenish the water supply to test the working of the new shower arm.

Do you see water coming from the female fitting? If yes, then tighten the connection a bit more, or you can remove the shower arm to use more plumber’s tape if required.

Tips on Replacing your Shower Arm

Installing a shower arm requires no rocket science at all, but preparing for this process is what you should definitely do! Here are some proven tips that can assist you while installing the shower arm.

Turn Off the Water Supply

It is quite obvious to turn off the water supply before installing a shower arm. But some people forget to turn it off in the excitement to reward their bathroom with a new look. Turning off the water supply will ensure that the water will not splash out of the female fitting during the installation.

Remove the Existing Shower Arm with Care

If the existing shower arm is faulty, then you should remove it before starting the installation process. Here is a quick method on how to remove a shower arm.

Turn off the water supply and then use a wrench to unscrew the shower arm. I would suggest you use the wrench carefully as the corroded arm can break while unscrewing.

Clean the female fitting before installing the new shower arm.

Prepare Your Surroundings

If you have some expensive showpiece items in your bathrooms or there is a chandelier installed on the roof, then you need to prepare your surroundings first. Use dry towels to cover the areas you think can get damaged in case the water oozes out with pressure.

Also, keep a dry towel handy to keep your hands dry during the installation process so that you can get a better grip over the equipment and tools.

Use a Shower Arm Extension if Required

If the shower arm is small in size, then you can buy a shower arm extension to use with it. With a shower arm extender, you can increase the length of the shower arm, and thus, the showerhead will reach the exact spot where you want it to be.


Q1: How to find out which end of the Shower Arm connects to the Female Fitting?

You can easily find out which end is meant for the female fitting by checking the shape of the shower arm. There is a slight bend in every shower arm at the end where the showerhead connects. The end, which is meant for connecting to the female fitting, is straight, and you can connect it easily with the vertical water supply line after applying plumbing tape.

Q2: What to do if the Shower Arm leaks after Installation?
