A lift apparatus includes a hydraulic lift assembly and a mounting assembly for releasably securing the apparatus on upper edge portions of a bathtub. The lift assembly is operable to raise or lower a user seated on a lift chair into and/or out of the tub. The lift assembly includes a support cylinder secured to the mounting assembly and a hydraulically actuable cylinder piston which may be selectively raised or lowered by regulating the flow of water into or from the cylinder. The lift chair is selectively movable by way of the lift assembly piston between an undeployed loading position, where the chair is positioned over the exterior edge of the tub, and a deployed position where the chair is moved over the tub and lowered to partially immerse the user. The mounting assembly includes a generally flat base plate having a length and width configured for juxtaposed contact with the upper surface of the tub side, and which has a downwardly open square C-shape. At least one cantilevered support arm is provided towards the ends of the base plate. The support arm extends horizontally to one side of the base plate to a respective distalmost end which rests against the upper surface of the inner side edge of the bathtub. A series of clamping elements are provided at longitudinally spaced locations along the base plate. The hand clamps are configured to allow their tightening against the sides of the tub, to firmly affix the base plate together with the bath lift in position over the exterior side of the tub.
