Why Is My Bathroom Always Humid?

Bathrooms produce a lot of moisture in a short period. If that moisture doesn't leave the room effectively, mirrors stay fogged, surfaces stay damp, and mold can develop.

Check the exhaust fan

Does the fan actually move air? A fan can make noise without moving enough of it.

Does it vent outside?

Bathroom exhaust should be handled according to applicable building requirements. A fan that simply pushes humid air into another part of the building can create moisture problems elsewhere.

Use the fan long enough

Run ventilation during bathing and afterward as needed to clear the moisture.

Keep the door strategy in mind

Air needs a path into the bathroom for an exhaust fan to move air out effectively.

Watch for recurring moisture

Persistent wet walls, peeling paint, mold, or damp trim means the moisture problem deserves attention.

Could there be a leak?

Not every bathroom moisture problem is humidity. Investigate localized stains or moisture that appears even when nobody has showered.
