How to permanently prevent mold in wardrobe from bathroom?« Back to Previous Page

The most effective long-term solution addresses the moisture source, which is likely migrating from your ensuite bathroom. In Dubai's climate, constant AC use creates a significant temperature differential, and the high humidity from showers can easily condense on cooler surfaces like that shared wall.

First, verify the bathroom's exhaust fan is functioning properly and venting directly outside, not just into the ceiling void. It should run for at least 30 minutes after every shower. For the wardrobe itself, installing a small, dedicated exhaust fan that vents outside is a highly effective solution, as it actively removes the humid air that seeps in.

The wall needs treatment. Remove all affected materials and have a professional treat the wall cavity with an antimicrobial coating. They should also install a vapour barrier—a sealed plastic sheet—on the bathroom side of the wall before retiling to physically block moisture transfer.

Finally, maintain lower indoor humidity. Keep your AC set to a consistent temperature and ensure its drain lines are clear. A standalone dehumidifier in the bedroom during the most humid winter months can provide additional protection. For a problem of this persistence, a professional inspection with moisture mapping is recommended to fully assess the extent of the issue within the wall.
