Abstract: A manufactured shower base assembly includes a thermoplastic honeycomb structure with a spun bond polyester fabric bonded to its base surface. The upper surface of the honeycomb structure is contoured to a desired slope and drain opening configuration, and includes a thermoplastic pre-formed thermoplastic waterproof membrane integrally bonded to its top surface, the membrane being contoured to conform to a shape of the honeycomb structure. A structural ring is utilized to provide added structure around the drain opening. The configuration allows for adjustment when placing/installing the shower base in relation to walls of the shower enclosure and to a floor drain in the shower enclosure, and further allows for attachment to any common clamping ring style drain, and provides for efficient and quick installation with minimization of skilled labor time.
