If you’ve had a hot shower for instance then you will have caused a lot of steam to rise off of you and that will cover all your walls and your windows as condensation (water vapor grips to walls to become condensation because they are the coolest part of the room, and it grips to the ceiling because heat rises and that’s cool too). At the same time you are likely to slosh huge amounts of water out of the side of the shower, just because we all do – and then when you step out onto the floor you’ll probably start dripping water onto your floor and causing it to get wetter still. If you then leave the room like this the condensation will start to dissolve the materials and if you have tiles these will be likely to start coming away from the walls and floor and this will damage your property. Once your tiles start peeling off then it’s definitely time to get bathroom renovations. Meanwhile other things can also get damaged by your condensation such as bathroom cabinets which can be equally destroyed by mold and condensation.
