Step By Step Guide

Step By Step Guide

In five simple steps, you’ll have a new shower arm installed and your water running just the way you like it! Let’s get to it.

1. Remove the Old Shower Head

Before installing a new arm, you’ll need to remove the old shower arm setup. Begin by unscrewing the old shower head to disconnect it from the old shower arm.

If the old showerhead has been screwed on by hand, you should be able to remove it by hand by turning it counterclockwise. If it has been screwed on too tightly, you’ll need a rag and a wrench or channel lock pliers to get it off.

In the latter case, place the rag around the base of the shower head and grasp it with your wrench or pliers. Twist counterclockwise until the showerhead disconnects from the old shower arm.

Then, place the rag on the base of the old shower arm and repeat this process with the wrench or pliers. Turn them counterclockwise to slowly unscrew the old shower arm from the water supply in the wall. The entire arm will turn with your wrench or pliers during this process, and you may want to complete the last few turns by hand to get a better grip on the hardware.

Remove the old shower arm and escutcheon from the wall.

Pro Tip: If the old escutcheon is stuck on the wall, it may be from mineral deposits or old glue. Run a utility razor under the rim. If this doesn’t work, use a liquid remover formula that will work on silicone.

2. Prepare the New Shower Arm

Prepare the New Shower Arm

Thread seal tape – also called plumber’s tape, Teflon tape, and PTFE film tape – is needed to prevent any leaks from your wall or shower head. This will save you time, money, and a headache in the future as you avoid potential water damage from shower leaks.

Grab your thread-sealing tape and wrap both ends of your new shower arm. When speaking of renovation projects, threads are the ridges on hardware, screws, bolts, etc. that allow parts to be screwed together. Threading is when you screw one item into another.

Wrap the thread-sealing tape clockwise on the threads of both sides of your shower arm. It’s important to wrap it clockwise so that it doesn’t unwrap when you thread the shower arm into the water supply line.

You’ll want to wrap the tape around the threads at least four times. Check out a video illustration below. You can put slightly less tape on the side of the arm that connects to the shower head (about 1-2 fewer layers).

Next, use your flashlight to peek into the hole that is now exposed in your bathroom wall. You may want to run your finger or a small clean brush along the sides of the hole to remove any debris or dirt that has accumulated on the threads over the years.

3. Insert the New Shower Arm

Place your new escutcheon on the end of the shower arm that will connect to the wall. It should slide on easily.

Then, insert the shower arm end into the wall and slowly thread it clockwise, by hand, to tighten it to the wall.

4. Install the New Shower Head

Your shower won’t be complete without adding the shower head to your shower arm. Installing a new showerhead can take as little as two minutes.

You will choose between a standard, fixed shower head or a handheld shower head that moves around and is connected to a plastic or metal hose.

  • Standard Showerheads

First, stabilize the shower arm where it connects to the wall by holding it with your hand and a rag or with a second wrench. You don’t want this part to turn or you could end up with an upside-down shower arm or a damaged internal pipe.

Once you have a strong grip on the arm, begin to thread your new shower head onto the end of the arm. You should be able to thread it snugly by hand. If you use a wrench, place a rag on the shower head first to prevent scratches on your new appliance.

  • Handheld Showerheads

Handheld Showerheads

Hand-held shower heads are similar to standard shower heads except they have an extra threading point where the hose connects to the shower head socket. Your new appliance should include a wall bracket/socket, the shower head itself, and a flexible hose.

Thread your wall bracket/socket onto the shower arm using the same method as for a standard shower head. Be sure the socket finishes so that the hole for the shower head is parallel to the floor, allowing your shower head to rest at the appropriate angle. Some sockets are adjustable.

Most hoses will have a shorter end and a longer end, and the shorter end should connect to the bracket/socket. If there is space for thread-sealing tape, add some to the threads of the hose ends. Some hoses may come with rubber washers and will not need tape.

Hand-tighten the hose to the bracket/socket. Then, hand-tighten the shower head to the other end of the hose.

Pro Tip: To conserve water and save on your water bill, choose a low-flow shower head replacement with a flow rate of less than 2.5 gallons per minute.

5. Check for Leaks

Turn your shower on and check for leaks around any of the areas you have threaded or tightened.

If the shower head leaks, stabilize the end of the shower arm with your hand or another wrench. Then, place the rag on the end of the shower head and turn it once tightly with your wrench. This should stop the leak.

If the shower arm leaks, try tightening it one turn with a wrench. If it continues to leak, you should remove it altogether, reclean the threads, reapply the plumber’s tape, and screw it back on.

Pro Tip: Always stabilize the shower arm base when tightening a part of your shower.

Extended Tips

  • Most shower arms are a standard size to fit virtually all models of shower heads, but it’s still important to double-check all measurements before purchase.
  • Place a towel in your tub over the drain before starting to prevent anything from falling down the drain or cracking your tub.
  • Read the manufacturer’s instructions for installation and follow these directions before any you find online. Your specific shower arm or shower head may be built differently than the standard model online guides are based on.
  • Some arms may come with rubber washers, eliminating the need for Teflon tape.
  • Always adjust your wrench or pliers to fit snugly around the item you’re unscrewing.
  • If your old shower arm won’t budge, don’t use brute force or move the shower arm side to side. This could break the internal female pipe that connects your water supply to your shower, costing thousands of dollars in damage. Instead, add another longer tool or pipe (wrench end, screwdriver, etc.) inside the shower arm and push on the tool as you loosen the arm with your wrench.
  • Clean your threads with an old toothbrush before putting on thread seal tape or screwing them on. Don’t forget to remove any old tape. This will make sure the shower arm and shower head are threaded as tightly as possible to avoid leaks.
  • When putting tape on the shower arm threads, make sure the tape doesn’t go past the threads or it will show and become dirty over time.
  • Some escutcheons have small metal plates that must be bent with pliers before installation. These allow the escutcheon to be placed firmly against the wall.
  • If your escutcheon seems to move around or be loose, add a ball of plumber’s putty to the bottom of it before installation, as shown at minute 2:43 of the video below.


To sum up how to install a shower head pipe, remember these key steps:

  • Remove your old shower head and arm
  • Use thread seal tape on your new arm
  • Thread in your new arm and escutcheon
  • Thread in your new showerhead
  • Check for leaks
