Abstract: A space expanding device is provided for temporarily expanding the available space defined by a shower curtain within a shower area of a bathtub. The device includes a first elongate planar portion which, in use, rests on an upper surface of the side wall of the bathtub. A second elongate planar portion affixed to one edge of the first portion extends, in use, downwardly from the first portion adjacent an inner side surface of the side wall. A third elongate planar portion affixed to the opposite edge of the first portion extends, in use, upwardly from the first portion away from the upper surface of the side wall. In use of the device, the third portion holds a portion of the shower curtain in a position spaced away from the interior of the bathtub, while a lower portion of the shower curtain is captured between the first portion of the member and the upper surface of the side wall of the bathtub and between the second portion of the member and the inner side surface of the side wall.
