My recently purchased home has improperly sloped walk-in tiled shower. I need to raise the floor around the current drain about two inches in order to create proper slope (1/4 " per ft.). The drain pipe in the concrete slab is 2" PVC. The drain strainer is 4" stainless with 3 3/8" between screw hole centers.
I intend to tile over the existing 2"x2" ceramic mosaic tile floor once the drain height is corrected.
Thanks.
