Your bathroom is by default a damp, humid place. However, it’s really important to ensure that all bathrooms in your home are well ventilated.
If you install proper bathroom ventilation you will not only limit condensation, but it will also help prevent mould and mildew, which can lead to nasty health issues. If mould is left to build up it can lead to respiratory problems, as well as skin complaints.
