A bathroom basin mixer tap is a key fixture that controls both hot and cold water through a single spout, offering a modern, space-saving, and elegant solution for contemporary bathrooms. Over time, taps may leak, corrode, or simply go out of style, leading many homeowners to consider replacement. Changing a basin mixer tap is a practical DIY task that refreshes the look of your sink and improves water efficiency if you choose a new model with updated internal components.
Before beginning, shut off the water supply under the sink. Most basins have isolation valves connected to the hot and cold supply lines—turn them clockwise to stop the flow. Then, open the tap to release any residual pressure. Place a towel or small bucket underneath to catch drips and make sure you have adequate lighting.
You’ll need several tools for the job: an adjustable wrench, a basin spanner for tight spaces, plumber’s tape, and a soft cloth to prevent scratches on metal surfaces. It’s also advisable to have new flexible hoses if the existing ones show wear or rust. Many modern mixer taps come with hoses and washers already included.
Start by disconnecting the water supply lines from the bottom of the old tap. Use a basin wrench to loosen the nuts holding the tap to the sink surface. Once the retaining nuts and washers are removed, carefully lift the old tap from the top of the basin. Clean the mounting area thoroughly—any limescale or sealant residue should be wiped away to ensure a smooth and watertight fit for the new tap.
Check the condition of the sink hole and the surrounding ceramic or stone. Cracks or uneven surfaces should be addressed before installation, as they can affect stability and cause leaks.
Insert the new mixer tap into the mounting hole, ensuring that any rubber or silicone gaskets are properly seated between the tap base and the sink surface. From underneath, thread the mounting plate and nut onto the tap tailpiece and tighten by hand first, then use a wrench to secure it firmly. Avoid overtightening, as this can damage the sink or distort the washer.
Attach the hot and cold water hoses—usually marked with red and blue indicators—to the corresponding valves. Apply a small amount of plumber’s tape to threaded connections for extra leak protection. Tighten the joints evenly, checking that the hoses are not twisted or kinked.
Turn on the isolation valves and let the water flow. Inspect all joints and the base of the tap for leaks. If any water seeps out, turn off the supply and slightly tighten the fittings. Run both hot and cold water for a few minutes to flush out debris and check that the mixer handle moves smoothly between temperature ranges.
At this stage, verify that the aerator at the spout delivers an even flow without splashing. If the pressure seems uneven, remove the aerator, rinse it, and reinstall. Proper alignment ensures comfortable use and consistent water output.
Regular maintenance extends the life of your basin mixer tap. Clean the surface with mild soap and a soft cloth; avoid harsh chemicals that can dull the finish. Every few months, check hose connections for tightness and look for signs of corrosion. If your area has hard water, soak the aerator in vinegar to dissolve mineral deposits. Periodic inspection of cartridges or seals can prevent small leaks from becoming major issues.
When selecting a replacement, prioritize solid-brass construction, ceramic cartridges, and corrosion-resistant finishes such as chrome, matte black, or brushed nickel. A high-quality tap ensures durability and smooth control of water flow.
