The answer to 'why is my bathroom moldy' is that bathrooms are naturally prone to mold growth due to the warm, humid environment. Mold thrives in damp conditions and can quickly spread if not addressed properly. Common causes of bathroom mold include poor ventilation, leaks, high humidity, and inadequate cleaning.
Mold in the bathroom can appear as black, green, or white spots on surfaces like tiles, grout, caulking, and even walls or ceilings. It can also cause a musty odor. Left untreated, mold can lead to health issues like respiratory problems, allergic reactions, and even structural damage to your home.
