We have two bathrooms in our house, one being a smallish en suite and the other being a rather larger bathroom/toilet/shower.
We have a perpetual problem with black mould growing in each other them, particularly on the ceiling. I have tried a number of strategies including paint the ceiling in mould resistant paint (worked for only a year or two) and regularly bleaching/boraxing the mould but it keeps on coming back.
Both bathrooms have extractor fans that we always use when using the bathrooms but we still have this problem. I was wondering if anyone had any suggestions – in all the other houses in which I have lived I have never had this issue.
I was wondering whether we needed a better fan and if so how you work out as to what the quality of the already installed fan is (it is old and I cannot work out its make)? The other thing I was thinking about is that the fan in the en suite is located on the side of the wall – I am wondering whether this may be an issue (in term of whether it is preferable to have them on the ceiling due to damper air being heavier than dry air and then gathering up next to the ceiling).

Biggest thing that would help is ventilation, open your window when you shower and leave it open well after you've finished. same with the extractor fan, leave it on for 10-20mins after you've done showering.
Other things i find helps:
If mirrors condense up, squeegee them and wipe dry.
The warmer you keep your bathroom, the less likely condensation will occur on your walls and ceiling.
Also bleach isn't a very effective mold killer, borax is good, but even better to use White Vinegar mixed with some borax, this will actually penetrate and kill the mold, unlike bleach.

Another tip is to actually take the door off and plane a few centimeters off the bottom. That inch of extra space lets a tonne more air through while the door is closed and boosts the efficiency of your extractor fans.
If no air can get in the bathroom, then you're extractor fan is really just spinning for almost no effect.
