Abstract: A shower curtain closure system for keeping a shower curtain fully extended across opposite walls of a bathtub area. The shower curtain closure system includes a flexible shower curtain for downwardly depending from the shower curtain rod. The shower curtain has a pair of side edges. The system also include a pair of elongate angle rods. Each of the angle rods has a longitudinal axis, exterior and interior faces, and first and second elongate portions substantially perpendicular to each other such that each angle rod has a generally L-shaped transverse cross section taken from a plane substantially perpendicular to the longitudinal axis of the respective angle rod. The first elongate portion of the angle rods is designed for coupling opposing wall surfaces adjacent a bathtub such that the second elongate portions of the angle rods are extended towards each other.
