Abstract: Elongated drain assemblies suitable for use in tiled shower stalls are described. Because the elongated drain is typically located at one edge of the shower stall proximate a stall wall and extends substantially the entire length of the wall, the installation of the associated shower pan is made much simpler. Specifically, the pan need only be sloped substantially in a single direction instead of four towards a prior art circular drain located at the center of a stall. 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.
