  • Bathtub liner
    Patent number: 4630323
    Abstract: An improved bathtub liner. The bathtub liner includes resilient pads encapsulated by a covering having a smooth continuous surface which detachably adheres to the inner surfaces of a bathtub and resists shear forces which tend to cause the continuous surface to slide over the inner surfaces of the bathtub. The bathtub liner includes a bottom pad shaped to cause water to flow under the force of gravity down the pad toward the bathtub drain when the tub is being emptied of water.
