The need to replace a bathroom sink may arise when one, your old sink is broken, and two, you need to renovate the entire bathroom. While you can certainly perform the job on your own, you have to understand first that replacing a bathroom sink can be really time-consuming. Nevertheless, it would be worth all your effort especially since you’re doing the task not just to improve the look of your bathroom but also to enhance your lifestyle. Meanwhile, the materials required to get the job done include a measuring tape, a putty knife, a wrench, sealant, a bucket, some cleaning rags, a screwdriver, and replacement sink.


Step 1. The first step in replacing a bathroom sink is to measure the sink. Using your measuring tape, get the dimensions of the sink, its depth, length, and width. Measure the dimensions of the counter top as well.

Step 2. Once you have taken the measurement of your old bathroom sink and the countertop it is resting in, only then should you buy the replacement bathroom sink. Take the measurements with you as you go the store to make sure you buy the right sink that would match your bathroom.

Step 3. Before you begin any kind of work, make sure to turn the water supply to the sink first. If possible, remove the faucet and the drain as well.

Step 4. Next, disconnect the plumbing from your old sink. Get the bucket and place it under the P trap. The P trap is where water is collected from your sink and once you disconnect it, so by placing a bucket under it, you are preventing water from getting all over the floor. Remove the drain as well by unscrewing it and getting rid of the existing putty using your putty knife. If there are any clips that connect the sink to the counter, you may want to remove them as well.

Step 5. The sink’s rim is connected to the counter top with sealant. Get rid of this sealant using your putty knife. Once you’re done removing all the sealant, you can gently lift the sink out and put it aside or throw it away.

Step 6. Next, apply sealant to the new sink and place it in the counter top. See to it that the new sink fits perfectly into the counter top. Get rid of excess sealant using a cleaning rag.

Step 7. Once the sink has been connected to the countertop, reinstall the P trap and the faucet next. If you are sure that there are no leaks, caulk the edges of the P trap.

Step 8. After connecting the P trap and the faucet, you can now test the new sink. Turn on the water supply and let water run freely from the faucet into the new sink. Check the edges of the sink and the connections as well and observe whether there are leaks or not. After a few minutes of observing and you see no leaks, you can congratulate yourself for a job well done.
