There may be other reasons as well, but mostly one or more than one out of the above may cause a bad smell emitting from your kitchen sink.

Identify The Cause

Before you enter into the remedial phase, you first have to identify what actually is the cause. To start with, check if there is any blockage in the drain pipe or the waste container of the sink. It is quite simple to ascertain; if water drains out easily, without any hindrance, out of your sink tub, there is no blockage in the drain pipe.

Next, closely examine the sink itself. It may have gone too old and despite of every effort, you can’t clean it properly. If this is the case, you have only one option; get the sink replaced, immediately. But if the sink is in a reasonable condition and there is no blockage in drain pipes, you need to move forward to identify the reasons of bad smell.

Identify the cause

The bad smell may also be coming from the sewerage or drainage system inside or nearby your kitchen, due to some sort of blockage. Here you will have to open the floor trap (situated somewhere near the sink in your kitchen), which is meant for draining out the water when you wash the floor of your kitchen. Dirt and various other things get accumulated here, which not only blocks the sewerage system but also causes the bad smell. Sometimes, this bad smell travels through the system and oozes out of the sink.


Now that you have identified the reasons for bad smell in your sink, let us move on to remedies.

  • If the bad smell is due to the deteriorated sink itself, get the sink replaced. In normal circumstances, you can do it yourself, easily. Just pull out the old sink and place the new one. But before that, you have to disengage the water supply and drain pipes. After placing the new sink, properly connect the water supply and drain pipes. If you feel it difficult, you have to call the plumber for doing it.
  • If the problem is with the main sewerage system inside the kitchen, you need to try cleaning it. Man products are available in the market that help clean the drainage; try using one of these. You may also try to pour very hot water along with the cleaning product. That helps a lot in cleaning the drainage. But if the problem persists, you may have to call any professional to clear the drainage system.


  • If there is a blockage in the drain pipe or waste container of the sink, the most effective way of getting rid of it is to remove the pipe, take it away and clean it with hot water and then replace it back, once the blockage is cleared. But if the installation is such, that you cannot easily remove the pipe, you will have to adopt other ways.
  • If you are unable to remove the drain pipe, don’t worry. Take a cup of baking soda and pour it in the sink. After a while, splash the sink with very hot water. Hot water, together with baking soda, is a very effective treatment for bacteria that cause the bad smell.
  • Further, you can also use white vinegar to clean the drain pipe and sink. Pour some white vinegar in the drain pipe and after a while, splash it with very hot water. Doing so, the inner lining of drain pipe will be cleared of any leftover food particles and bacteria.

Apart from the above, you may use the cleaning products, readily available in your local market. Buy one such product, of a well-reputed company and wash your sink, following the instructions of the manufacturer.

Finally, why should you wait for the sink to start emitting bad smell? Don’t wait, make it your regular practice to clean the drain pipe with either of the above methods, periodically, so that the chances of bad smell are reduced.
