A collapsible bed bath article which is erectable over the mattress of a hospital-style bed and provides a water impervious enclosure having a drain for rinsing a bed bound patient. In one embodiment, side panels of the article are equipped with pockets which are configured to fit over portions of raised side rails of a hospital-style bed. In another embodiment, a pocket for a side rail of a bed may be produced on an ad hoc basis by adhering portions of each side panel to itself, or to the side rail, thus forming a partial encapsulation of the bed side rail.
