How to replace a shower head

Overview

There are many reasons to replace a shower head. Perhaps you’d like better water pressure, or are looking to save water or energy. If your old shower head is leaking, rusty, or clogged with minerals, that’s another good reason to replace it. Or maybe you’re looking to upgrade your bathroom or want something that’s easier to use, like a hand-held shower head. Whatever your reason, learn how to replace your shower head in this D.I.Y. guide.

Safety tip: Always wear the appropriate safety equipment (safety glasses, gloves, ear muffs and a mask, for example) and always follow the instructions for the product or equipment.

Steps

  1. 1

    Turn off the water supply

    To prevent any leaks or spills, start by locating the water supply to the shower and shutting it off.

    Remove the old shower head

    Using a shifter, grip the base of the old shower head where it connects to the shower arm (the pipe protruding from the wall). Turn the shower head counterclockwise to loosen it. Once loose, unscrew it completely and remove it from the shower arm.

    Remove the shower arm and take off the cover plate

    If you’ve got a separate shower arm, twist to remove this from the wall, too, along with the protective shower plate if you have one.

    Clean with a microfibre cloth

    Use a microfibre cloth or rag to wipe off any dirt, debris, or old tape from the threads of the shower arm. This will ensure a clean surface for the new shower head to attach to.

    Apply thread seal tape

    Wrap thread seal tape clockwise around the shower arm thread, taking care to ensure each layer overlap is neat and smooth. This will create a tight seal and help prevent leaks.

    Select a new shower head

    Now it’s time to select your new shower head. There are plenty of options to choose from, from water-saving styles that will help you conserve water (and money) to high-pressure shower heads to twin shower systems. If you have sensitive skin or hair, it might be worthwhile to invest in a filtration shower head which removes impurities for cleaner water.

    Consider factors such as water pressure, flow rate and compatibility with your existing plumbing. Look for adjustable spray settings, ergonomic design, style and easy maintenance, as well.

    Install the shower arm and head

    If you removed a cover plate earlier, or are installing a new one, mount this onto the shower wall.

    Next, screw the new shower arm by hand, turning it clockwise. Once it's hand-tightened, use your adjustable shifter and a cloth to give it an extra quarter turn to make sure it’s a snug fit.

    Now, repeat the same motion when securing your new shower head. Be careful not to overtighten, as this can potentially damage the shower head or the shower arm.

    Conduct a test run

    Once the new shower head is securely in place, turn the water supply back on using the shut-off valve. Check for any leaks around the connection between the shower head and the shower arm.

    If you notice any leaks, tighten the connection a little more using your shifter; apply more thread seal tape if required. Make sure to check for unusual noises and adjust the water flow and temperature as needed.

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.
