The answer to 'bathroom odor' is that there are several common causes, including poor ventilation, mold growth, plumbing issues, and improper cleaning. Bathroom odors can be a sign of a larger problem that requires attention.
Poor ventilation is a common culprit, as moisture and humidity can build up and create musty smells. Mold growth, often hidden behind walls or under fixtures, can also contribute to bathroom odors. Plumbing problems, such as a blocked or leaking drain, can lead to unpleasant sewer-like smells. Lastly, improper cleaning or not using the right cleaning products can allow odors to linger.
