Abstract: A Doorless Shower Enclosure System is a water handling system for human showering which is configured in such a way as to fit into an alcove in a bathroom of approximate size as that of a bathtub, and effectively contain and discharge water from a shower head, without the use of a physical door. The system is composed of a prefabricated base with a drain, a glass partition, and a metal crossbar support. The glass partition rests upon the base and is supported at the top by the metal cross bar, which is mounted to the side walls of the alcove. Access to the shower compartment is through a walk-in opening, as opposed to an operable door.
