How to Change Bathroom Basin Taps Step-by-Step
Replacing your bathroom basin taps is a straightforward home improvement task that can make a big difference in the look and functionality of your bathroom. Whether your current taps are leaking, outdated, or simply not to your taste, learning how to change them yourself can save you time and money on a plumber, and give you the satisfaction of a successful DIY job.
In this guide, we’ll walk you through everything you need to know to change your bathroom basin taps step-by-step. From understanding why you might want to replace them, to gathering your tools and following the correct procedure, we’ve got you covered.
Why Change Your Bathroom Basin Taps?
Changing your basin taps can be driven by necessity or design preferences. Here are a few common reasons homeowners take on this task:
1. Leaks and Drips
A dripping tap isn’t just annoying, it can waste a surprising amount of water and increase your utility bills. If fixing the washers or cartridges doesn’t stop the leak, replacing the whole tap may be the better option.
2. Outdated Fixtures
Old-fashioned taps can date your bathroom and drag down its overall aesthetic. Swapping them for a sleek, modern design is a quick way to refresh your space.
3. Improved Functionality
Upgrading from separate hot and cold taps to a single mixer tap can provide better temperature control and convenience, especially for families with young children.
4. Water Efficiency
Many new tap designs are made with water-saving technology, helping you reduce water use without sacrificing performance.
What You’ll Need: Tools and Materials Checklist
Before you begin, gather the following tools and materials to make sure your project runs smoothly:
Tools:
- Adjustable spanner or basin wrench
- Bucket or container
- Screwdrivers (flat-head and Phillips)
- Towels or rags
- Plumber’s tape (Teflon tape)
- Hex key (if required for your specific tap)
- Allen keys (for some modern taps)
- Cleaning cloth and bathroom cleaner
Materials:
- New basin tap(s)
- New flexible hoses (if not included with your tap)
- Tap washers or cartridges (if needed)
- Silicone sealant (optional for sealing around the base)
You can typically find these items at your local hardware store or plumbing supply shop. Some retailers even provide tap installation kits that include most of what you’ll need.
Step-by-Step Guide to Changing Bathroom Basin Taps
Here’s a breakdown of how to safely and efficiently change your bathroom basin taps:
Step 1: Turn Off the Water Supply
Start by turning off the water supply to your basin. Most basins have isolation valves under the sink, turn these clockwise to shut off the water. If there are no isolation valves, turn off the main water supply to your home.
Once off, open the existing taps to release any remaining water in the pipes.
Tip: Place a towel or bucket underneath the basin to catch any drips or spills.
Step 2: Disconnect the Water Supply Hoses
Use your spanner to loosen and remove the nuts securing the hot and cold supply hoses from the bottom of the tap. Be gentle to avoid damaging the fittings.
If your tap is an older model, you may need to disconnect copper pipes. Flexible hoses are much easier to install and are generally recommended for replacements.
Step 3: Remove the Old Tap
Look underneath the basin for the nut that holds the tap in place. Use your basin wrench or spanner to loosen this nut and remove it completely. Once it’s free, lift the old tap out from the top of the basin.
Clean around the tap hole thoroughly to remove any limescale, grime, or sealant before installing the new tap.
Step 4: Install the New Tap
Position your new tap into the mounting hole on top of the basin. From underneath, secure it with the fixing nut provided with your tap. Tighten it firmly, but avoid over-tightening which can damage your basin.
If your new tap has a gasket or rubber seal, ensure it’s positioned correctly to prevent leaks.
Step 5: Attach the New Flexible Hoses
Connect the new flexible hoses to the base of your tap and then to the isolation valves or supply pipes under the sink. Make sure you connect the hot and cold supplies to the correct inlets.
Wrap plumber’s tape around the threaded connectors to create a tight seal and help prevent leaks.
Step 6: Turn the Water Supply Back On
Once everything is connected, slowly turn the water supply back on. Open the tap and check for any leaks around the hoses and base. If you notice any drips, gently tighten the connections.
Let the water run for a minute to clear out any debris or air trapped in the pipes.
