How to Replace a Bath Tap

Posted by ilker Duymaz on

Over time, bath taps can wear out, leak, or simply become outdated in terms of aesthetics. Replacing a bath tap is an effective way to rejuvenate the look of your bathroom and can be an ideal DIY project for the weekend. If you've ever tackled plumbing challenges like fixing a running toilet or unblocking a shower drain, you'll find this task relatively straightforward. Here's a step-by-step guide to help you on your way.

How to Replace a Bath Tap

1. Gather Necessary Tools

Ensure you have the right tools on hand:

  • Adjustable wrench
  • Basin wrench
  • PTFE tape
  • New bath tap
  • Bucket and old towel

2. Turn Off the Water Supply

Before starting, ensure the water supply to the taps is turned off. It's usually done at the isolation valve beneath the taps or by turning off the main water valve.

3. Remove the Old Tap

Place a bucket or towel under the tap to catch any residual water. Using the adjustable wrench, unscrew the tap connector nut. Once detached, use the basin wrench to remove the nuts that secure the tap to the bath. Lift the old tap out of the bath.

4. Clean the Surface

Before installing the new tap, make sure the surface is clean. Remove any old sealant, limescale or debris. If you've noticed a significant build-up of limescale around your old taps, you might want to read up on how to remove limescale effectively from other bathroom fixtures.

5. Install the New Tap

Place the rubber washer on the base of the new tap. Position the tap in the designated hole on the bath. From underneath, screw on the retaining nut to secure the tap in place. Use a basin wrench to ensure it's tightened securely.

6. Reconnect the Water Supply

Wrap the end of the tap connector with PTFE tape to ensure a watertight connection. Reconnect the tap connector to the tap tail and tighten it using the adjustable wrench.

7. Test the New Tap

Turn on the water supply and check the tap. Ensure there are no leaks and the water flow is consistent. If you encounter a peculiar odour from your drain after this exercise, don't fret. It's a common issue, and you can find solutions in our guide on how to fix a smelly bathroom sink.


Replacing a bath tap can significantly uplift the look and functionality of your bathroom. By following the steps above and ensuring that you have the right tools, this DIY project can be accomplished smoothly, saving you the cost of hiring a professional. As always, remember to ensure the water supply is off before starting and to test your new tap thoroughly once installed.
