How to avoid getting mould within bathroom?
All accurate answers yes you need dutiful ventilation and invest within a good standard bathroom fans, near are some which operate by detecting moisture content in the upper air. Mould just loves heat up and damp conditions next to still air. On a personal principle I keep my bathroom ably heated and well vent this seems to save the mould at bay. Good Luck
I have found since buying an ancient cottage (1870) with a feebly constructed bathroom the secret is proper heat and ventilation.
We have an old porthole with no vent and in winter especially it would run near water and effect mould on the ledge.
We installed a latest double glazed window next to an air vent and since consequently (2 Years ago) have have no problems with mould.
Answers: Invest in a obedient extractor fan, initiate windows when possible, quit shower door/curtain open after shower. Also using a squeegee or out-of-date towel to dry off walls after shower works, although not something you want to do when rushing to catch ready for work. If you do achieve any mould spray with some diluted chlorine bleach (open pane wide first) and walk off to dry.
