A shower curtain assembly for covering an opening of a shower enclosure includes a housing that defines an internal space. The housing is configured to couple to a substrate so that the housing is positioned proximate to an opening of a shower enclosure. A slot is positioned through a bottom of the housing. The slot extends substantially between opposing ends of the housing. At least one panel, which is flexible so that it can be rolled, is positioned in the internal space. A first end of the at least one panel is positioned through the slot. The slot is positioned to selectively extend the at least one panel from the housing to cover the opening of the shower enclosure.
