Yes, in most kitchens you can replace a tap without changing the sink. The main thing is that the new tap suits the holes already in the sink or worktop. As long as the fit is right and there is room to work underneath, the sink can usually stay where it is.
Matching the New Tap to the Existing Holes
Start by counting the tap holes. Many modern sinks have one hole, which suits a monobloc mixer tap. Older sinks often have two holes for a pair of pillar taps, one for hot and one for cold.
If you have two holes and want a single mixer, there are options. A two-hole bridge mixer may fit straight in, or one hole can sometimes be covered with a blanking plate. Going the other way, from one hole to two, is much harder and may mean a new sink.
Hole size matters too. Most taps are made to fit a standard hole, but some sinks have smaller or larger holes. Check the size the tap maker asks for before you buy.
Sink-Mounted or Worktop-Mounted Taps
Some taps sit on the sink itself, while others are fitted through the worktop beside it. This is common with undermount sinks and some stone or solid worktops. If your current tap goes through the worktop, the new one will need to do the same.
Deck thickness is easy to miss. A thin stainless steel sink and a thick stone worktop need different fixing lengths. Many taps come with fixings for a set thickness range, so check that your sink or worktop falls within it. If the tap cannot be held firmly, it may wobble and loosen over time.
What Happens Under the Sink
Access is often the hardest part of the job. The fixing nuts sit high up behind the bowl, sometimes in a tight space near the back of the cabinet. Old nuts can be stiff or seized, which can make removal slow.
It helps if there are isolation valves on the hot and cold pipes. These let a plumber turn off water to the tap alone, rather than the whole house. If there are none, fitting them during the job can make future repairs much easier.
Most new mixer taps use flexible tails to connect to the pipework. Sometimes the existing pipes need a small change to meet these tails neatly. A tidy, well-supported connection is less likely to leak.
When a New Sink Might Make Sense
Sometimes the sink itself is the problem. It may be chipped, stained, cracked or the wrong shape for how you use your kitchen. If the holes simply will not suit the tap you want, it may be worth looking at a new sink installation or replacement at the same time.
For most people, though, a straight swap is all that is needed. Our page on replacing and fitting new taps explains how we approach kitchen and bathroom tap jobs.
