condensation on bathroom walls is a common problem, especially in older homes. There are a few things you can do to help reduce or eliminate the problem.
First, try to ventilate the room as much as possible. Open a window or door when you shower or bathe, and run an exhaust fan if you have one. This will help to remove the moisture from the air and prevent it from settling on the walls.
Second, make sure that your walls are properly insulated. This will help to keep the warm air inside the room and prevent the cold air from seeping in and causing condensation.
Third, try using a dehumidifier in the room. This will help to remove the moisture from the air and keep the relative humidity at a lower level.
Fourth, try to keep the room temperature as consistent as possible. sudden changes in temperature can cause condensation to form on the walls.
If you follow these tips, you should be able to reduce or eliminate the problem of condensation on your bathroom walls.
