Where do these bad smells come from?

If your bathroom smells bad, it’s probably related to a pipe problem. To be sure, simply move closer to the sink or shower drain. Typically, stubborn odors emanate from these sources and are so strong that they can really affect your comfort. Sewer odors in particular are often linked to the siphon, the curved part of the pipe that always contains a little water and is responsible for preventing sewer odors from rising. Several causes can explain their appearance:

  • A plumbing defect, if the toilet flushes the shower or sink trap
  • A faulty trap that no longer blocks bad odours
  • A clog that has formed in the trap due to hair, soap residue or other waste, which encourages the growth of microbes
  • Bad odours coming from the tank in the sewage system or a lack of maintenance

People who live in apartments can find out if the problem is individual or if it applies to everyone in their building. When neighbors complain of the same unpleasant odors, chances are that the sewer odors are actually related to a defect in the facilities such as lack of ventilation.

There’s nothing better than a home remedy to fight bad odors in the bathroom. The secret? Combine white vinegar and baking soda. Together, these ingredients work synergistically to create a chemical reaction that eliminates those lingering scents. Here’s how to use them:


  • 1 cup of water
  • 1 cup of white vinegar
  • 5 tablespoons of baking soda

How do I do it?

Start by boiling the water and vinegar. At the same time, remove the shower drain grate and pour the baking soda directly on the surface. Do the same with the sink trap.

When the water and vinegar have reached a boil, carefully pour the liquid over the baking soda and leave for 30 minutes. The chemical reaction that occurs will cause the mixture to foam up and clean the pipes to eliminate the sewage smell. All that’s left to do is run the water to remove the smell.2 tips to maintain your pipes daily
