How Can You Tell If Your Bathroom Sink Is Blocked?

Generally, several signs will give you a hint that your bathroom sink is blocked. If you notice any of the following symptoms, then you know you have a blockage:

  • Bad smells
  • Other plumbing blocked (toilet, shower)

What Causes A Blocked Bathroom Sink?

As we said before, your bathroom sink may become clogged for many reasons. That is why it is best to leave it to our professionals to identify the problem and provide a long-term and effective solution. The following are some of the most common causes of blocked bathroom sinks:


You may not notice, but a great deal of hair slips down the drain. When hair accumulates continuously, it forms clumps that collect soap scum and other debris, slowing water flow.

Soap Scum

Lime soap, also known as soap scum, is formed when minerals in hard water react with fatty acids in soap. Over time, scum accumulates, attracting mould and mildew and clogging your drain.

Mineral Build-Up

Hard water evaporates when heated, forming precipitates of minerals suspended inside. Eventually, this solidified scale (or limescale) can accumulate inside your pipes, causing a blockage.

Tree Roots

Often, tree roots slither into cracks in pipes in search of water. They may also become entwined in underground pipes. Eventually, this will cause a crack or blockage in your pipeline, resulting in a blocked bathroom sink.

Corroded Pipes

As your pipes corrode, rust begins to roughen the walls, and objects become trapped inside. Ultimately, this results in a plumbing system blockage.

Blocked Bathroom Sink FAQs

Do you have more questions about your blocked bathroom sink? Check out our most commonly asked questions below:

If your bathroom sink is making strange sounds, it’s likely because it’s blocked. A common cause of a blocked bathroom sink is when people put things down the drain that shouldn’t be there, like hair or food. Another cause could be a build-up of soap scum. You can try to unblock your sink by using a plunger or a drain snake, but if that doesn’t work, you’ll need to call a plumber.

It depends, but we would not recommend it. If the blockage is caused by a clog of hair or other debris, the sink can clear the blockage over time. However, if a build-up of limescale causes the blockage, it is less likely that the sink will unblock itself. In this case, it may be necessary to call a professional plumber to clear the blockage.

If your bathroom sink is blocked, one possible culprit could be candle wax. While it might seem like an unlikely cause, if you’ve recently burned a candle in your bathroom, the wax can harden and block your sink’s drain. If you think this might be the problem, simply remove the wax with a putty knife or similar tool. If that doesn’t work, you may need to call a plumber to take a look. In the meantime, avoid using your sink until the issue is resolved.
