Many Individuals Are Unfamiliar With How To Use It

Many bathroom sinks feature a small hole near the faucet, which might seem like an unnecessary detail to some. However, this hole serves an important purpose.

Positioned about a third of the way up the sink basin, this hole is an intentional design element meant to prevent potential flooding. It connects to the drainage system below and acts as an overflow outlet. If users accidentally leave the faucet running—such as when they step away to answer a phone—the hole allows excess water to drain before it can spill over and cause a mess on the floor.

Despite its benefits, this overflow hole can sometimes lead to problems, such as bacteria and mold buildup, which might result in unpleasant odors.

If you encounter a bad smell emanating from this hole, a simple solution involves mixing vinegar and baking soda and pouring the mixture into the sink. The reaction between the two substances will help clear out any grime from the pipes within about 5 to 10 minutes. Afterward, rinse the sink with warm water to complete the cleaning. This approach will help keep your bathroom smelling fresh and clean.
