A bath lift features a lifting plate (16) connected to a hydraulic lifting hose (12) which raises it as water is supplied, and lowers it as water is drained out. Fitted to the underside of the lifting plate (16) is a manual control valve (18), from which a connection hose (20) leads to the hydraulic lifting hose. A further hose element (24) of the manual control valve (18) ends at a coupling element (22) which serves to connect a pressure-water supply hose. The manual control valve (18) also has a drain port which, in one operating position of the manual control valve, communicates with the hydraulic lifting hose (12). In the other operating position, the hydraulic lifting hose (12) is connected to the pressure-water supply, and in a neutral central position, the manual control valve shuts off the hydraulic lifting hose from the pressure-water supply and the drain port. The lifting plate (16) has a second opening (28) the same size as opening (26), and this is located at the other longitudinal side of said lifting plate (16). Furthermore, an identical arrangement of fixing holes (30) is provided on both sides of this second opening (28). In addition, the lifting plate (16) features a further fixing hole arrangement (44). The second opening (28) and the described fixing holes are, in the standard bath lift design, without function and are covered by a cushion mat. In order to provide the bath lift with a connection for a hand-held shower attachment, a shut-off spool/slider valve (48) is bolted into the second opening (28), which valve (48) features a connection fitting (50) for the shower hose and a connection (46) leading to a manifold (35) from which a further hose element (38) leads to a coupling element (40), this latter being connected not to the pressure-water supply but to coupling element (22) of the first manual control valve (18). Manifold (35) features a coupling element (36) for connection of the pressure-water supply. The bath lift can thus be expanded by a retrofit set to include at least one further pressure-water connection, without the need to rework the lifting plate (16).
