Leaving the bathroom door open after showering helps humid air escape. Using an exhaust fan can also remove moisture before it settles and may help reduce musty odors and damage to paint, grout, or drywall.
If keeping the door open is not practical because of children or pets, the exhaust fan can be left running for around 30 to 60 minutes. Opening a window and wiping down wet surfaces can also improve drying.
Overall, better ventilation after a shower is the most important thing. Keeping the bathroom dry and allowing moisture to escape can reduce mold growth, protect the room, and improve indoor air quality.
