A leaking shower tap is more than just an annoyance—it can lead to water wastage, higher bills, and potential damage to your bathroom. If you’ve noticed persistent dripping from your shower tap, don’t ignore it. This guide will walk you through the steps to fix leaking shower taps yourself and help you determine when it’s time to call a professional plumber.
Understanding the Causes of a Leaking Shower Tap
Before diving into the repair process, it’s important to understand why your shower tap might be leaking. Common causes include:
- Worn-out washer – The rubber washer inside the tap wears out over time, allowing water to seep through.
- Faulty O-ring – A damaged or worn O-ring can cause leaks around the handle.
- Corroded valve seat – Mineral deposits and corrosion on the valve seat can lead to leaks.
- Cartridge issues – If your shower tap has a cartridge, it may be clogged or damaged.
- Loose or damaged parts – Over time, screws and seals may loosen or degrade, causing leaks.
Step-by-Step Guide to Fixing a Leaking Shower Tap
If you’re confident in your DIY skills, follow these steps to repair your leaking shower tap:
Step 1: Turn Off the Water Supply
Before you begin, locate your home’s main water shut-off valve and turn it off to prevent water from flowing while you work. Open the leaking shower tap to drain any remaining water in the pipes.
Step 2: Remove the Tap Handle
Use a screwdriver to remove the screw securing the tap handle. If it’s hidden, you may need to pry off a small decorative cap to access it. Gently pull the handle off the tap.
Step 3: Remove the Cover Plate & Expose the Valve
If your shower tap has a cover plate, unscrew or pry it off carefully. This will expose the valve mechanism underneath.
Step 4: Unscrew & Remove the Valve Stem or Cartridge
- For compression taps, use a wrench to unscrew the packing nut and remove the valve stem.
- For cartridge taps, pull out the cartridge after removing the retaining clip or nut.
Step 5: Inspect & Replace the Washer or Cartridge
- If your tap has a washer, check for wear or cracks. Replace it with a new one of the same size.
- If your tap has a cartridge, inspect it for damage or debris buildup. Replace it if necessary.
Step 6: Check & Clean the Valve Seat
Use a cloth or small brush to clean the valve seat. If it appears corroded, use white vinegar to remove mineral buildup.
Step 7: Reassemble the Tap & Test
Reinsert the new washer or cartridge, tighten all parts securely, and reattach the handle. Turn the water supply back on and check for leaks. If there’s no dripping, your repair is successful!
When to Call a Professional Plumber
While many minor leaks can be fixed with a DIY approach, there are situations where calling a professional is the best option. Consider professional help if:
- The leak persists even after replacing the washer or cartridge.
- The valve seat is severely corroded and needs professional resurfacing.
- You’re dealing with a complex shower system, such as a thermostatic or digital shower.
- The plumbing behind the wall is damaged or leaking.
Benefits of Hiring a Professional Plumber
A licensed plumber brings expertise and the right tools to handle complex issues efficiently. Some benefits of professional help include:
- Accurate diagnosis – Plumbers can quickly identify and fix hidden problems.
- Long-lasting repairs – Quality workmanship ensures your tap won’t start leaking again soon.
- Time-saving solutions – Avoid trial and error with a professional fix.
- Warranty on work – Many plumbers provide a guarantee for their repairs.
Preventing Future Shower Tap Leaks
To minimize the risk of future leaks, follow these simple maintenance tips:

- Clean your shower tap regularly – Remove mineral deposits to prevent buildup.
