How to dry a bathroom after a shower
Remove liquid water first, then keep air moving long enough for the remaining moisture to leave the room.

Run the exhaust fan, squeegee wet walls or glass, spread towels and the shower curtain, wipe puddles, and leave ventilation operating after you finish.
1. Vent outdoors
Use a properly ducted exhaust fan during the shower and afterward. If outdoor conditions and home security permit, a window can supplement airflow. A fan that vents into an attic transfers the moisture problem rather than solving it.
2. Remove surface water
A squeegee moves far more water than evaporation. Focus on glass, large tile surfaces and ledges. Wipe puddles around the tub, toilet and vanity so grout and edges do not stay wet.
3. Open wet textiles
Spread towels on separate bars and extend the shower curtain fully. Move a saturated bath mat to a drying position. Bunched fabric dries slowly and can reintroduce odor.
4. Check performance
Persistent mirror fog, dripping walls or condensation that lasts for hours can indicate inadequate airflow, a blocked fan, excessive indoor humidity or hidden leakage. Clean the fan grille only with power safely isolated and follow the manufacturer instructions.
When to investigate further
Repair active leaks. Soft drywall, expanding staining, widespread mold or recurring respiratory symptoms require appropriate professional or medical advice. The EPA guide explains why moisture control is fundamental.
