How to Replace a Shower Head: A Step-by-Step Guide
Last updated: 22 October 2026
Replacing a shower head is a simple DIY job that can improve your showering experience without replacing the entire shower. Whether you're changing an old shower head, upgrading to a rainfall design or replacing a handheld shower head, the process is usually straightforward if the new fitting is compatible.
In this guide, we'll explain how to remove an old shower head, fit a replacement, deal with stubborn connections and check everything is working correctly.
Can You Replace a Shower Head Yourself?
Yes, most standard shower heads can be replaced without a plumber. If your shower head screws onto a threaded shower arm or hose, you can usually remove it by hand and install a compatible replacement.
You generally won't need specialist tools, although an adjustable spanner and a soft cloth can help with stubborn fittings.
Important: This guide covers replacing the shower head itself. If you need to open the shower unit, alter plumbing connections or work on electrical components, use a suitably qualified professional where required.
What You'll Need
Before you start, gather the following:
- Your new compatible shower head
- An adjustable spanner, if needed
- A soft cloth to protect chrome fittings
- A small cleaning brush or old toothbrush
- A suitable replacement washer, if required
Check whether your replacement shower head includes a washer and whether it is designed to fit your existing shower hose or shower arm.
How to Replace a Shower Head in 5 Steps
Step 1: Turn Off the Shower
Switch off the shower and allow the water to cool before handling the fittings. Make sure the shower is not running while you work.
If you're replacing a handheld shower head, check how it connects to the hose. If you're replacing a fixed shower head, identify where the head screws onto the shower arm.
Step 2: Remove the Old Shower Head
Try unscrewing the old shower head by turning it anticlockwise when viewed from the connection end.
Many handheld shower heads can be removed by hand. If the fitting is tight, wrap a soft cloth around the connection and use an adjustable spanner carefully to loosen it.
Avoid gripping the chrome directly with metal tools, as this can scratch or damage the finish. Do not force a seized fitting, particularly if the shower arm or pipework starts to turn.
Step 3: Clean the Connection and Check the Washer
Once the old shower head is removed, clean away any limescale or debris around the connection using a soft cloth or small brush.
Inspect the rubber washer or sealing ring. A damaged, missing or incorrectly positioned washer can cause leaks, so replace it if necessary.
Check the threads for damage and make sure the connection is clean before fitting the replacement. Most standard shower head connections seal using a washer, so avoid adding PTFE tape unless the fitting manufacturer specifically recommends it.
Step 4: Fit the New Shower Head
Check that the new shower head has the correct connection for your existing shower arm or hose.
Position the washer correctly, then screw the replacement head on clockwise by hand. Tighten it securely without overtightening, as excessive force can damage the threads or washer.
If you're fitting a handheld shower head, check that the hose connection is secure and that the hose isn't twisted or kinked.
Step 5: Test for Leaks
Turn the shower on and allow the water to run for a short time.
Check around the connection for drips or leaks. If water escapes from the joint, switch the shower off, check the washer is correctly seated and carefully retighten the connection.
Once everything is secure, test the spray settings if your new shower head has adjustable functions.
How to Remove a Stuck Shower Head
If your old shower head won't unscrew, limescale or corrosion may have built up around the connection.
Try these steps:
- Make sure the shower is switched off and cool.
- Wipe away any visible limescale around the joint.
- Hold the connection steady and try turning the head anticlockwise by hand.
- If necessary, use an adjustable spanner with a soft cloth to protect the finish.
- Stop if the shower arm or pipework begins to twist, or if the fitting appears seized.
Avoid applying excessive force or using heat near plastic fittings. If the connection remains stuck, a plumber can help remove it without damaging the pipework.
How to Replace a Rainfall Shower Head
Replacing a rainfall shower head follows much the same process as replacing a standard fixed shower head.
First, check how the existing head connects to the shower arm. Unscrew the old head anticlockwise, clean the connection and inspect the washer.
Before installing the replacement, check its diameter, thread type, weight and compatibility with the existing shower arm. Larger rainfall heads may need a suitable supporting arm and adequate water flow to perform correctly.
Fit the new head by hand, tighten carefully and test for leaks. If you need to change the shower arm or alter the plumbing, seek professional advice.
How to Replace a Shower Head and Hose
If you're replacing both a handheld shower head and its hose, you can usually remove them separately without replacing the shower valve.
- Switch off the shower and allow it to cool.
- Unscrew the hose from the shower head.
- Unscrew the other end of the hose from the shower outlet or holder connection, as applicable.
- Check both connection points and remove any dirt or limescale.
- Fit the new hose with the correct washers in place, then attach the compatible shower head.
- Turn the shower on and check both ends for leaks.
Make sure the new hose has compatible fittings and is suitable for your shower system. Do not assume every shower hose or head uses the same connection.
Why Is My Shower Head Leaking After Replacement?
A leak after fitting a new shower head is often caused by a simple connection issue.
Common causes include:
- Missing or damaged washer: Check that the rubber washer is present and correctly seated.
- Loose connection: Switch off the shower and tighten the fitting gently by hand.
- Cross-threaded connection: Remove the head and refit it carefully, ensuring the threads engage correctly.
- Incompatible fittings: Check the replacement head matches your existing connection.
- Damaged threads: A worn or damaged shower arm or fitting may need replacing.
If the connection continues to leak after you've checked the washer and fitting, avoid overtightening it. Seek professional advice if you suspect damage to the pipework.
How Often Should You Replace a Shower Head?
There is no fixed replacement interval for every shower head. A well-maintained shower head can last for years, but replacement may be worthwhile if it becomes damaged, develops persistent blockages or no longer performs properly after cleaning.
Regularly removing limescale, particularly in hard-water areas, can help maintain water flow and keep the spray pattern consistent.

Frequently Asked Questions
Can I replace a shower head without a plumber?
Yes. Most standard screw-on shower heads can be replaced by hand using a compatible fitting and washer. If the job involves altering pipework or opening an electric shower unit, professional assistance may be needed.
Do I need to turn the water off to change a shower head?
For a standard screw-on shower head, you normally only need to switch the shower off and ensure the water has cooled. If you're changing plumbing connections or working on the shower unit itself, follow the manufacturer's instructions and isolate the water supply as appropriate.
Do all shower heads fit all shower hoses?
No. Many handheld shower heads use common threaded connections, but compatibility should always be checked. Fixed shower heads, rainfall heads and specialist systems may use different fittings.
Should I use PTFE tape when fitting a shower head?
Usually not on a standard shower head connection that seals with a rubber washer. Check the manufacturer's instructions, as some specialist connections may require a different sealing method.
Why is my new shower head leaking?
The most common causes are a missing or damaged washer, a loose or cross-threaded connection, or incompatible fittings. Check the washer and refit the head carefully before considering other repairs.
Can I replace just the shower head without changing the hose?
Yes. If the existing hose is in good condition and the new shower head is compatible with its connection, you can replace the head alone.
How do I remove a shower head without scratching it?
Try loosening it by hand first. If you need a spanner, wrap a soft cloth around the connection to protect the finish and avoid applying excessive force.
