Beis Plumbing, serving the St. Louis area, explains the top reasons your bathroom sink smells and what you can do about it.
Why Does My Bathroom Sink Smell?
There are several reasons your bathroom sink smells. According to the CDC, stagnant water and organic debris are common culprits for household plumbing odors.
- Buildup of hair, soap scum, and toothpaste in the drain
- Clogged or dirty P-trap
- Mold or bacteria growth in the pipes
- Dry drain traps allowing sewer gas to escape
- Leaky or damaged plumbing connections
Ignoring a smelly sink can lead to bigger plumbing problems and even health risks.
How to Fix a Smelly Bathroom Sink
If your bathroom sink smells, try these steps to eliminate the odor:
- Clean the drain with a mixture of baking soda and vinegar
- Remove and clean the P-trap under the sink
- Run hot water to flush out debris
- Check for leaks or loose connections
- Pour water into rarely used drains to refill the trap
According to Angi, regular cleaning and maintenance can prevent most bathroom sink smells.

Preventing Future Bathroom Sink Smells
To keep your bathroom sink smelling fresh, Beis Plumbing recommends several simple maintenance practices. Regular drain cleaning helps prevent the buildup of soap scum, toothpaste residue, and other debris that can create unpleasant odors over time. It’s important to avoid pouring grease or food down the bathroom sink, as these substances can accumulate in the pipes and cause blockages and bad smells.Â
Using drain covers to catch hair and debris before they enter your plumbing system is another effective preventive measure that reduces the likelihood of clogs and odor-causing buildup. Finally, scheduling annual plumbing inspections allows professionals to identify and address potential issues before they become major problems, ensuring your bathroom sink and entire plumbing system remain in optimal condition.
