Mold above shower - what to do?

if it black, it is most probably poor ventilation

Turn out the light so you cant see it, wear a neck brace so you cant look up or call an expert who can give you a proper solution.

You need an extractor to get out the steam or your extractor is blocked or falty. You could clean it with some sugar soap.

Hi, building regs state that bathrooms in newduilds, with or without windows, must have an extractor fan. This a recommendation for bathroom refurbishments.
Your bathroom needs extraction/ventilation if at all possible, as the high moisture levels are causing the mould. If you ned further assistance please call my mobile, regards John

Hello , You Need to install a Fan extractor , also your ceiling type might be the issue easy to get mould so you need to treat with special material to prevent that
