The present invention relates to a kit for use in a shower enclosure with a shower curtain. The kit contains a wall component, a connecting component and a retaining component. The wall component has a back wall and at least one front wall, and is removably attachable to a wall surface of the shower enclosure. The connecting component has both a front portion and back portion. The back portion is detachably connectable to one of said at least one front wall of the wall component by means of magnets attached thereto. Once the wall component and connecting component are connected together, they form a watertight barrier. The front portion of the connecting component contains a protrusion in the form of two spaced apart, elongated arms that are each provided with an abutting edge against which part of the shower curtain may be positioned. The retaining component is detachably connectable to the protrusion of the connecting component with the part of the shower curtain snapped in between. The retaining component has a pair of arms with end edges that face toward each other and are sized to snap onto the abutting edges of the elongated arms of the protrusion of the connecting component with the part of the shower curtain pinched in between.
