How to safely remove black mold in shower?« Back to Previous Page

My kids have been coughing more than usual, and I finally found the source – a patch of black mold has started growing in the corner of our master bathroom shower, right where the tiles meet the ceiling. We've lived here for 2 years and just noticed it, probably because the humidity has been so high lately. What's the most effective way to get rid of this safely and permanently, and should I be calling my landlord first or just handling it myself?

Black mold in showers is common here due to Dubai's high humidity and condensation from hot showers. For a small patch (under one square foot), you can handle it safely yourself. Wear an N95 mask and gloves. Scrub the area with a dedicated mold remover or a solution of white vinegar or diluted bleach. The key is to address the moisture source – run the exhaust fan for at least 30 minutes after every shower and wipe down wet surfaces.

Because the mold is at the ceiling junction, there's a possibility it has spread behind the tiles, especially if the grout is cracked. DIY cleaning only removes surface growth. If it returns within a few weeks, the issue is internal. For persistent mold or if anyone in the household has respiratory sensitivities, a professional inspection is warranted to assess the extent.

You should notify your landlord, especially if a re-grouting or leak repair is needed, as that is typically their responsibility under Dubai rental regulations. They are obligated to provide a habitable property, which includes addressing underlying moisture issues causing mold. Document the issue with photos before you clean it and send a written notification to them. If the problem is severe or recurrent, professional remediation may be required to properly remove the colony and treat the area to prevent regrowth.
