ABSTRACT:
A cover for a bathtub overflow port includes a concave body provided with a circular inner edge maintaining a vacuum seal with an inner surface of the existing bathtub. Such a circular inner edge of the body is removably abutted directly against the inner surface of the existing bathtub during operating conditions. The inner edge of the body creates a vacuum within the body when the inner edge of the body is abutted against the inner surface of the existing bathtub. Such a vacuum statically affixes the body to the inner surface of the existing bathtub during operating conditions. The cover further includes a curvilinear handle provided with axially opposed ends.
