Abstract: A sealing member is provided for a bathtub. A conventional plate is coupled to the wall of a bathtub and covers a drain opening formed therein. The plate is continuous except for an overflow opening which accommodates the free flow of water from the bathtub through the drain opening and down the overflow drain of the bathtub. The sealing member sealingly engages the plate and the bathtub wall to prevent water from flowing through the overflow opening of the plate and down the overflow drain of the bathtub. The sealing member includes an annular lip which fits snugly within the overflow opening of the plate. In an alternate embodiment, a bypass opening is formed in the sealing member at a height greater than that of the overflow opening of the plate. A channel formed within the sealing member extends between the bypass opening and the overflow drain. Water may then enter the sealing member at a height greater than the overflow opening and be channeled through the overflow drain and out of the bathtub.
