I recently got an extractor fan fitted in our ensuite and its not directly over the shower, it drips constantly in the mornings on to the floor after two showers (very annoying when trying to use the mirror where it is with water dripping on your head). I open the window while showering and there is still mould on the ceiling in one part. I've tried bleach, that special paint for mould and its still coming back. The attic is also insulated. I also have a vent in there and its still not working. There is no radiator in there though, could this be the problem or is it something else? So sick of trying to figure out what the problem is.
