Replacing your shower head is one of the easiest home improvement tasks you can do yourself. Most shower heads simply screw on and off, requiring no special tools and no plumber. In fact, the entire process typically takes less than 15 minutes from start to finish. Whether you're upgrading to a more efficient model, replacing a worn fixture, or simply changing the style of your bathroom, this guide will walk you through the process step by step.
Australian homes use standard plumbing fittings that are compatible with the vast majority of shower heads sold in the country. As long as your new shower head is designed for Australian connections, which virtually all products sold through Australian retailers are, you shouldn't encounter compatibility issues.
What You'll Need
Before you begin, gather these supplies:
- New shower head - Ensure it's compatible with Australian standard fittings
- Plumber's tape (also called thread seal tape or PTFE tape) - Available at any hardware store
- Adjustable wrench or adjustable pliers - For removing stubborn fittings
- Soft cloth or rag - To protect finishes and clean threads
- Old towel - To catch any drips
Before You Start
You don't need to turn off your water supply to replace a shower head. Simply ensure the shower taps are fully off before you begin.
Step 1: Remove the Old Shower Head
Start by examining how your current shower head is attached. Most shower heads screw directly onto the shower arm, which is the pipe protruding from the wall. There may also be a decorative flange or escutcheon plate against the wall, but this typically doesn't need to be removed for shower head replacement.
Hand Removal
First, try unscrewing the shower head by hand. Grip the shower head firmly (not the arm) and turn anticlockwise. Many shower heads can be removed this way, especially if they've been installed relatively recently.
Using Tools
If the shower head won't budge by hand, you'll need to use an adjustable wrench. Before applying the wrench, wrap a soft cloth around the shower arm to protect the finish from scratches. Then, grip the shower head with the wrench and turn anticlockwise. Hold the shower arm with your other hand to prevent it from rotating.
Important
Never apply excessive force to the shower arm itself. The arm connects to plumbing inside the wall, and forcing it can cause leaks or damage that requires professional repair.
Step 2: Clean the Shower Arm Threads
With the old shower head removed, you'll see the threaded end of the shower arm. This needs to be clean before installing your new shower head.
- Remove any old plumber's tape from the threads. It often comes off in strips or may need to be picked off.
- Wipe the threads with a clean cloth to remove any debris or old sealant.
- Check the threads for damage. If they appear stripped or corroded, you may need to replace the shower arm, which is a more involved job.
Step 3: Apply New Plumber's Tape
Fresh plumber's tape ensures a watertight seal between the shower arm and your new shower head. This step is essential for preventing leaks.
- Hold the end of the tape against the threads at the base of the shower arm (closest to the wall).
- Wrap the tape clockwise around the threads when viewed from the end. This direction ensures the tape tightens as you screw on the shower head rather than unwrapping.
- Overlap each wrap slightly as you go, covering all the threads.
- Make two to three complete layers of tape.
- Tear or cut the tape and press the end down firmly.
Step 4: Install the New Shower Head
Now for the satisfying part: installing your new shower head.
- If your new shower head has multiple components (such as a handheld unit with a hose and mount), identify which piece connects directly to the shower arm.
- Align the shower head's threading with the shower arm and begin turning clockwise by hand.
- Continue hand-tightening until snug. The shower head should be secure but you should still be able to adjust its angle.
- If the shower head needs to be tightened further to stop at the correct position, use an adjustable wrench with a protective cloth. Tighten only slightly beyond hand-tight.
Installation Checklist
- Old shower head removed carefully
- Threads cleaned and inspected
- New plumber's tape applied clockwise
- New shower head hand-tightened first
- Final position adjusted if needed
- Tested for leaks
Step 5: Test for Leaks
Turn on the water and let the shower run for a minute. Check carefully around the connection between the shower head and the arm. A small drip or spray from this joint indicates the connection needs to be tightened slightly more, or the tape may need to be reapplied.
If you notice water coming from behind the wall plate or from the arm itself, turn off the water and consult a plumber as this indicates a more serious issue.
Installing a Handheld Shower Head
Handheld shower heads follow the same basic process but include additional components. Typically, a bracket or holder mounts to the existing shower arm threads, and the handheld unit connects via a flexible hose. Some handheld systems include a diverter that allows you to switch between the handheld unit and a fixed head.
Follow the manufacturer's instructions for your specific model, but the principles remain the same: clean the threads, apply plumber's tape, hand-tighten first, then test for leaks.
Troubleshooting Common Issues
Shower Head Points in Wrong Direction
Most shower heads have a ball joint or swivel that allows angle adjustment. If yours doesn't, you may need to slightly loosen and reposition the entire unit on the arm.
Persistent Leak at Connection
Remove the shower head, add an additional layer of plumber's tape, and reinstall. Ensure the tape was wrapped in the correct direction.
Low Water Pressure After Installation
Some shower heads include a filter screen or flow restrictor. Check the manufacturer's instructions to locate and clean or adjust these components if needed.
