Should I handle bathroom mold myself or tell my landlord?« Back to Previous Page

Based on your description from Jumeirah, what you're seeing is classic mold growth fueled by our extreme UAE humidity. The black discoloration in the grout is likely mold spores, and the fuzzy patches behind the toilet are active colonies.

For a small, surface-level issue, a DIY approach can be attempted. You'll need to address the moisture source first—ensure your bathroom's exhaust fan is working properly and run it during and for at least 30 minutes after showers. For cleaning, use a dedicated EPA-approved fungicidal cleaner, not just bleach, as bleach only removes the surface color and doesn't kill the root system. Scrub the affected grout and the area behind the toilet thoroughly.

However, given the location (behind fixtures) and the persistent humidity, there's a high probability the growth extends deeper, possibly behind the tiles or under the flooring. This is where DIY fails and becomes a potential health risk by aerosolizing spores.

Under UAE tenancy law, the landlord is typically responsible for addressing issues related to the building's structure and maintenance, which includes persistent dampness and mold resulting from inadequate ventilation or waterproofing failures. You should absolutely report this to your landlord promptly. Document the issue with clear photographs and a written notification. A professional inspection is strongly recommended to determine the full extent; we use thermal imaging and moisture meters to find hidden moisture that's not visible. If the landlord is unresponsive, Dubai Municipality can be contacted.
