Removing the old sink
It is a good idea to have a picture of your plumbing before removing the old sink. This way, you will have a reference for when you start fitting the new one. To remove your old sink, start by ensuring your water is turned off at the stopcock, and relieve any built-up pressure by turning the taps on.
Next, you need to disconnect your water pipes. Using a wrench, unscrew the supply lines (you will need a bucket to catch any leftover water). Make sure you have plenty of towels around to avoid damaging your flooring. Using pliers, you can now disconnect the drainpipe and other pipes from the sink drain.
Once you have disconnected the pipes, simply look for the metal fastenings that connect the sink to the counter. These can be loosened with a screwdriver and need to be moved towards the bowl of the sink so it can be lifted out.
Carefully cut through the seal that goes around your sink with a Stanley knife. The slower you work, the less likely you are to scratch the surface. Once satisfied with your cutting skill, this should now allow you to remove the sink unit by pushing it up and out from below.
Finally, clean the area of grime and build-up; you want the area to be as clean as possible for the new fixture. This will also allow the new caulk to stick properly.
Fitting the new sink
Before getting started, just check that the new sink fits in the old space. Simply lift it into the gap and check you are happy with its size (if it doesn’t fit, then you will need to alter your countertop).
Using the clips from before, you want to now attach them facing inwards to the bowl of the sink.
You can now install the taps and any other parts of the sink, such as a waste dispenser.
Using plumbing putty, go around the drain strainer and, pressing hard, install the strainer (you only need a small bit of putty for this). You can now put the sink on one side and apply the rubber gaskets and threaded flange to the sink drain. Remember to protect your surfaces by putting a protective sheet down. This will also prevent damage to the new sink. Once complete, wipe away any excess putty and apply a small amount of silicone sealant around the edge of the sink.
You are now ready to fit your sink in, lowering it gently into the gap and making sure it is lined up properly. Once you are happy with its placement, go ahead and fix the clips below the sink, fastening any nuts or screws while you are there.
You are ready to reconnect your water supply; simply reattach the water connections for the tap and the supply pipes, ensuring they are tightly secured (but not overly tight). The picture you took of your plumbing may come in handy here.
Finally, apply some sealant to the edge of the sink, and you have done it; you just need to turn your water back on and ensure there are no leaks.
