There's nothing worse than walking into your bathroom and being hit with a musty, unpleasant odor. And often, the culprit is a stale water smell coming from your bathroom sink. This can be a frustrating and embarrassing problem, but thankfully, it's one that can be easily fixed.

If you notice a musty smell coming from your bathroom sink, the first thing you should check is the drain.

If your bathroom sink has old or dirty piping, it can also contribute to a stale water smell. Over time, residue and grime can build up inside the pipes, creating a breeding ground for bacteria and mold. This can cause a musty smell to emanate from your sink. To get rid of this smell, you may need to replace your pipes or use a pipe cleaner to remove any buildup.3. Old or Dirty Piping
Leaving water to sit in your bathroom sink for a long period of time can also cause a stale water smell. If you have a habit of letting water sit in your sink, it's important to drain it regularly to prevent bacteria and mold growth.

A lack of proper ventilation in your bathroom can also contribute to a stale water smell. Without proper airflow, moisture can become trapped in your sink and lead to bacterial growth.

If you use your bathroom sink for rinsing dishes or washing your face, you may experience a stale water smell due to grease and food buildup.

In rare cases, a stale water smell may be caused by sewer gas entering your bathroom through a dry P-trap. The P-trap is designed to hold a small amount of water to prevent sewer gas from entering your home. If the P-trap dries out, it can allow sewer gas to seep through, causing a foul odor. You can solve this issue by running water down your sink or pouring a cup of water into the drain to refill the P-trap.7. Sewer Gas
