 Wet rooms are bathrooms where the shower floor and bathroom floor are one continuous waterproof surface.Such floor designs allow a wheelchair user using a dedicated shower chair, or transferring onto a shower seat, to enter the shower without needing to overcome a barrier or lip.The construction of low floor trams and buses is increasingly required by law, whereas the use of inaccessible features such as paternoster lifts in public buildings without any alternative methods of wheelchair access is increasingly deprecated.
