What Causes The Smell In Your Bathroom Sink?

• Proliferation of Bacteria: As previously mentioned, bacteria thrive in the organic matter that accumulates in your drain and produce a gas called hydrogen sulfide, which results in a foul smell.
• Inadequate Ventilation: When your bathroom sink lacks proper ventilation, it can trap the odor and prolong its lingering presence.
• Troublesome Sewer Lines: A damaged sewer line or a blocked sewer vent pipe can cause sewer gas to seep into your bathroom through the sink drain, resulting in an unpleasant smell.
• Dry P Trap: The P trap, a curved pipe under your sink, is responsible for holding water to prevent sewer gas from entering your bathroom. However, if there is no water in the P trap, it can allow the smell to travel up through your sink.

In conclusion, a foul smell in your bathroom sink can be caused by bacteria buildup, inadequate ventilation, sewer line troubles, or a dry P trap.
