The invention provides that a bath has one or more shoulders which receives or receive the lower edges of one or more shower screen panels which forms or form a means preventing water from passing over the side of the bath. The shoulder or shoulders is or are formed by distinct steps on the insides of the bath, at the top edge thereof, so that the upright side face or faces of the shoulder or shoulders form an obstruction preventing the panel or panels from swinging out beyond the sides of the bath. The said panel or panels preferably are adapted to be supported through seal means on said shoulders when in use so that the shoulder effectively shed shower water back into the bath and preferably there are two groups of panels defining front and transverse sections of a shower cubicle over the bath, the panels of each group being suspended from the ceiling of the bathroom and being hinged together so as to be capable of being folded concertina fashion to lie parallel to each other and to an adjacent bathroom wall in a stowed position.
