The Pre-Pitch is a stay-in-place screeding guide for use underneath shower pan liners. It creates the proper slope for water to flow towards the weep holes in the floor drain, helping to keep water, which could encourage mold and mildew growth, from being trapped between the mud bed and the liner. The Pre-Pitch is easily cut with a hacksaw, PVC cutters, or grinder and can be used on wood subflooring or concrete. The Pre-Pitch Standard Kit costs $23 and the Extended Kit costs $24. Using both kits, a contractor can pitch a 10-foot-by-10-foot area with a centered drain. goofproofshowers.com
