The time and cost of creating a pan having a single slope is reduced over a more complex multi-sloped pan. Several different means for adjusting the height of the drain assemblies' top surfaces relative to the height of the tile floor are provided to adjust for tile floors of differing thicknesses.

Abstract: A shower enclosure base has a flow enhancing flush-mounted drain cover that conceals the drain opening and provides a flat stepping surface. Drain flow is achieved through a narrow peripheral passage between the drain cover and the drain well in which it is seated.

These features are radially converging ribs at the underside of the drain cover that interrupt the natural tendency for drain water to form a vortex as it passes into and through a circular drain opening. The drain cover can be removably secured to the base by suction cups that attach to the drain well.
