built a new shower (shower only, no tub) and am about to install my shower drain to my 2" stub in the floor. it's the three peice drain (drain body, clamping ring, and strainer body). at what level should the top of the drain body flange be? level with the slab or higher? i get conflicting opinions. the shower floor will be tiled over sloped base over a membrane shower pan.

You want and need to have the top of the bottom plate that attaches to the pipe flush or a bit below the slab. I like it a bit lower to help allow any water that sets it the pan to be able to seep thru the weep holes that you see on the bottom of the top clamping ring.. Suggestion that almost nobody knows.. You should put a hand full or two of pea gravel around the drain base before you put in your mud ( cement) base. This lets water thru but doesn t allow the mud to clog the weep holes. Any questions you can e mail me thru my avatar and check my qualifications there GL
