How to change a shower head

DIY- Header- How to change a shower head

Overview

A new shower head can make a big difference to your daily routine. Whether you're looking for a stronger spray, better water coverage or simply want to refresh the look of your bathroom, replacing a shower head is a simple bathroom upgrade that can often be completed in just a few minutes.

Steps

1

Choose a compatible shower head

Before purchasing a new shower head, check the product packaging to ensure it's suitable for your existing shower setup and water pressure. Most shower heads use standard fittings and are designed to fit most Australian shower arms, but it's worth confirming before you buy. If you're unsure, take a photo of your current shower head and arm, or bring the old shower head into store for advice.

2

Turn off the water

While not always essential, turning off the water supply before starting can help avoid any unexpected sprays or leaks while you're working. If you don't have easy access to the isolation valve, ensure the shower is turned off completely before beginning any plumbing work.

3

Remove the old shower head and arm

Unscrew the existing shower head by turning it anti-clockwise. In many cases, you can do this by hand. If it's difficult to remove, wrap a cloth around the fitting to protect the finish and use adjustable pliers for extra grip. Take care not to damage the shower arm while loosening the fitting.

4

Clean the shower arm thread

Once the old shower head has been removed, inspect the thread on the shower arm. Remove any old plumber's tape, mineral deposits or build-up using a cloth. A clean thread will help create a better seal and reduce the risk of shower leaks.

Apply plumber’s tape

Wrap plumber's tape around the thread several times, overlapping slightly as you go. When looking directly at the end of the shower arm, wrap the tape clockwise so it follows the direction the new shower head will be tightened. This helps prevent the tape from bunching up or unravelling during installation. The tape helps create a watertight seal and can make future removal easier.

Install the new shower arm

Screw the new shower arm onto the existing shower outlet by turning it clockwise. Start by hand to avoid cross-threading, then tighten until secure. Check the manufacturer's instructions for any specific installation requirements and avoid overtightening, which can damage the fitting or thread.

Attach the shower head

Once the shower arm is installed, attach the shower head according to the manufacturer's instructions. Most models simply screw onto the end of the arm and can be tightened by hand. Make sure the shower head is positioned correctly before moving on with the shower head installation.

Test the spray pattern

Restore the water supply and run the shower for a minute or two. Check around the connection where the shower head meets the shower arm for any signs of leaking. If you notice drips, turn the water off and tighten the fitting slightly or apply a little more plumber's tape.

Once you're happy there are no leaks, test the shower head and check that the spray pattern is working as expected. If your new shower head has multiple spray settings, try each one to find the option that best suits your needs.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
