There exist plenty of different reasons behind the leakage of a bathroom sink. Whereas it is very much possible that the reason behind the leakage of a sink is entirely unique, under normal circumstances however, the reason is pretty repetitive in most cases. There are two very common reasons why a sink leaks. The first and also truly common cause is the entering of water on the counter, which then seeps through the part where the bowl is attached to the countertop. On the other hand, a loose faucet can also trigger water leakage a large number of times.

When a bathroom sink leaks for whatever reason, it is essential to fix it immediately. The above two problems do not require much money to be corrected or fixed. Also, fortunately, the process of fixing a sink is easier and less time consuming than most people think!

  1. You should be able to locate a few nuts under the bathroom sink, on the faucet stems. Tighten those nuts, which will lead to overall tightening of the faucet to the top of the sink. For the purpose of tightening the nuts well, make use of a basin wrench. Keep in mind that trying to use too much force may lead to over-tightening, causing the faucet to break.
  2. On the part where the sink and the vanity top meets, also known as the sink edge, have a little amount of water poured. Observe carefully to find out whether water leaks through or not.
  3. If you find that water still keeps on leaking through the bowl edge, it is time to use a good utility knife to remove the existing caulk, found near the bowl.
  4. Using a rag and putting some mineral spirits on it, make sure that you clean the part around the bowl as best as you can. The more complete the cleaning, the better!
  5. Around the part where the bowl and the vanity top touch, apply the caulk carefully to make it even. In order to have the crack found between the countertop and the bowl removed, spread the caulk using your finger in order to make very even bead, thus filling the crack nicely.
  6. With the help of mineral spirits put on rag, clean the bowl as well as the counter to remove any unwanted caulk that may exist. Do not wet the sink for 24 hours after this process. Have the caulk dried fully before using water.

As you have seen already, it is not really hard to fix a bathroom sink. All you need to do is make sure that you execute the above steps carefully and accurately. So the next time you have your sink leaked again, just remember the steps you just read, or in case you forget, know that this article is always here to help! If the above explanation fails to do the trick, go ahead and call a professional, because the problem may be something else entirely.
