How to change a shower head

Signs you need to change your shower head

Not sure whether it’s time for a replacement? Let’s look at some common signs that your shower head may need changing:

• Stubborn mineral build-up that won’t come off, even after cleaning
• Constant dripping or leaking, even when the shower is turned off
• Reduced water flow or uneven spray patterns compared to what you used to have
• Strange noises, such as whistling or rattling
• A shower head that’s not been changed in a long time

If you’ve noticed one or more of these issues, fitting a new shower head could make a noticeable difference.

How to change a shower head easily in five steps

Replacing a shower head is usually a simple DIY job that most homeowners can complete in under 30 minutes.

Tools needed to change a shower head

Before you begin, gather the following:

• New shower head
• Adjustable wrench or slip-joint pliers
• Teflon tape if necessary (also known as PTFE tape or plumber’s tape)
• Clean cloth
• Rubber gloves
• An old toothbrush (for cleaning threads)
• A towel to protect fixtures and cover the drain

1. Prepare the area

First, make sure the shower is fully turned off. Then, lay a towel down in the shower and over the drain. This will protect the surface from scratches and stop small parts from falling down the drain while you work.

2. Remove the old shower head

Most shower heads can be unscrewed by hand by turning them anticlockwise. If it’s stuck, wrap the base of the shower head in a cloth to protect it from scratches, then use slip-joint pliers or an adjustable wrench to loosen it gently. Avoid using excessive force, as this could damage the shower arm.

3. Clean the shower arm

Once the old shower head is removed, check the threaded end of the shower arm. Use a clean cloth or an old toothbrush to remove any mineral deposits, old tape, or debris. This step is important as a clean thread ensures the new shower head fits securely and helps prevent leaks and damage.

4. Install the new shower head

Screw the new shower head onto the shower arm by hand until it feels snug. Most new shower heads come with a washer to make sure there’s a tight seal. If there isn’t a washer, you may need to wrap the threads of the shower head in Teflon tape. Check the instructions that came with your shower head for guidance.

5. Test for leaks

Turn the water on and check for any drips around the connection. If you notice leaks, turn the water off, remove the shower head, and check the washer or apply another layer of Teflon tape, and reattach it. Test again to make sure everything is sealed properly.

Common questions about changing a shower head

How often should I change my shower head?

It’s often recommended to replace your shower head every 3–5 years, particularly in areas with hard water. However, with regular cleaning and good maintenance, a quality shower head can last much longer.

It’s better to keep an eye out for signs like leaking, stubborn mineral build-up, or reduced performance, rather than just age, as these are usually better indicators of whether a replacement is needed.

Can changing a shower head increase water pressure?

While a shower head can’t change your home’s overall water pressure, different designs can affect how the water feels when it comes out.

Some shower heads are specifically designed to optimise flow, which can improve the shower experience even if your mains water pressure remains the same.
