Standard shower drain requirements call for a 2” waste line size and are 2-piece bolt together type. These may be made of a variety of materials, ABS, cast iron, etc. some also may have an adjustable height drain screen. All drains need to be installed to achieve the minimum amount or movement. On wood sub-floors secure with straps to prevent up and down movement and do not cut an oversize hole in sub-floor this prevents side to side movement. Drains on slab need to be level, with sub-base level or at slab height and back-fill the access hole to with-in ½” of floor.
Trough Drains:
When making your own trough the area where the drain will be needs to be recessed, a standard drain can be used, and the recess should be of significant depth that the drain top is at the height of your trough bottom. This applies to either wood or concrete sub-floors, a minimum of 2” from drain flange edge to recess should be maintained. 8” wide X 6” deep X length needed is a standard formula.
Specialty Drains:
Pre-made troughs are available and some can be hot-mopped in place. Please call with manufactures name and we can verify if your product can be used.
Thunder-bird deck drains and custom built copper sluice and or trough drains can also be mopped-in, depending on local codes.
