Hot showers fill your bathroom with moisture that can encourage mold, mildew, and musty odors.
Leaving the door open and using the exhaust fan helps humid air escape instead of settling into walls and fabrics.
If you need to keep the door closed for children or pets, run the fan for 30–60 minutes and crack a window when possible.
Dry towels and mats, squeegee wet surfaces, and make these simple habits part of your routine.
