Preparing shower drain on concrete slab
I have read through the liberry and many other posts and I have gained tremendous information and potentially some knowledge (time will tell).
I purchased a house where the basement was "mostly finished". They had planned to install a shower and had done some of the preliminary work. They have the plumbing roughed in, the drain pipe set in concrete, the walls have backer board, etc.
Here is my question.
I need to prepare the shower drain prior to sloping, waterproof membrane, etc. but I am not sure how high the flange around the drain should be above the concrete floor once it is attached to the drain pipe. I see lots of examples for wooden subfloors but not alot of examples with slabs. I assume from most of the posts that 3/4 is a good target to allow room for the pre-slope.
Ultimately, we will be installing a straight curb acoss the opening and stone tile for the floor (2") and walls (18").
You can see the broad view of the shower in the first picture. It shows the drain pipe coming out of the floor and gives you a sense of the overall project.
The second picture shows the drain sitting on the concrete floor next to the drain pipe. Obviously I can not just cut off the pipe and use it at that height (boy would that have been easy). But how high should it be when complete.
The third picture is just to show you that the floow is not tile. It is a stained and textured thinset that is designed to look like tile. I do not plan to remove this under the shower.
Any help before I rent a concrete chipper and go to town?
