Abstract: A tile-ready shower base system including a composite curb, and methods of manufacturing and installing the same. A sloped structural core is provided having a top side and a bottom side. A first waterproof panel or coating is applied to the top side and a second waterproof panel or coating is applied to the bottom side. A thin fiberglass flange is provided about at least a portion of the perimeter of the core to create a lip. The basin further includes a first hole or recess formed into the basin, which does not extend through the basin, and a second hole, axially aligned with the first, which does extend through the basin, for directly receiving and coupling a drain therein. The composite curb is provided along at least one side of the basin. Optionally, a compressible soft material or cushioned layer can be applied over the first waterproof panel of the sloped structural core.
