How much should professional bathroom tile cleaning cost?« Back to Previous Page

That slimy, dark grout is a classic sign of microbial growth, a common issue here due to our high ambient humidity and the constant condensation from air conditioning. Scrubbing often just spreads the surface spores without addressing the root problem embedded in the porous material.

For a standard villa bathroom, the cost for professional tile and grout cleaning isn't fixed. It's primarily determined by the square footage of tiled area and the severity of the biological contamination. Expect the scope to include a high-temperature steam clean to disinfect, followed by a specialized extraction to remove the moisture and debris. In many cases where the growth is visible and slimy, the grout will likely need a full restoration—cleaning, sanitizing, and sealing—to prevent immediate recurrence.

Given the conditions you describe, I would recommend first having the growth professionally inspected to confirm it is surface mold and not a more persistent issue requiring remediation. Any reputable service provider should be able to assess the bathroom, provide a detailed scope of work, and offer a transparent quote based on that specific assessment. Always request this; a company that gives a fixed price over the phone without seeing the job may not be thorough. The final step should always be the application of a quality sealant to protect your grout from Dubai's humid environment.
