An expanding curtain does not require the addition or installation of a new curved rod and/or any external curtain supports, control devices, or adapters to expand the usable space in the enclosure area and/or prevent the inward intrusion of the curtain towards the user. Rather, the curtain itself may have the strength, rigidity and/or fortitude to form an outwardly extended shape (e.g., away from the enclosure area) that may hold it in place, thus, expanding the amount of space available for utilization by the user of the enclosure area. The curtain easily and rapidly mounts and thereafter may be easily slidable/manipulated between an open and closed position. The curtain may surround, divide and/or provide privacy to a specific area and/or confined space. The curtain may also maintain a mold, mildew and germ resistant facade, while remaining inexpensive to manufacture.
