How to Extend a Shower Head Arm

The arm of your shower head is the piece of plumbing that extends from the wall and suspends the actual shower head. Most of the time, the existing shower arm will accommodate a change in shower heads without any alterations. However, if you are particularly tall, or would like to install a rain shower head, extending the shower head arm may become a necessity.

Extending an Existing Shower Arm

If your original shower arm is in good condition, and you are not installing a specialty shower head, buying an extension for your existing shower arm is a simple and inexpensive solution.

Step 1: Remove the existing shower head by turning the head counterclockwise. If possible, use your own hands for this step, using one hand to steady the shower arm. If it is too tightly attached to the shower arm, wrap a rag around the head, then use an adjustable wrench to remove the shower head.

Step 2: Clean the threads of the shower arm with a toothbrush and white vinegar to remove any residual water marks.

Step 3: Screw on the shower arm extension with your hands in a clockwise direction.

Step 4: Turn on the water and check for leaks. If you see a leak, try twisting the shower arm more firmly into place. If necessary, you can use a piece of plumber’s tape on the threads.

Replacing the Existing Shower Arm

If you intend to install a rain shower head, or other type of specialty head, you may find that replacing the entire arm with a new shower arm is the best option.

Step 1: Unscrew the shower arm by twisting in a counterclockwise direction. To loosen the connection between the shower arm and the plumbing, you may need to use an adjustable plumbing wrench for the first few turns.

Step 2: Clean the threads of the pipe that is attached to the wall with an old toothbrush and white vinegar. Remove any existing plumber’s tape. Rinse and allow the threads of the pipe to dry completely before continuing.

Step 3: Apply plumber’s tape to the threads. Screw the new shower arm into place. Click here to find a Plumber in Chino Hills, CA
