I want to replace an old basement shower with a shower kit. The existing shower drain appears to be just a regular floor drain to which the concrete floor was sloped. The slope is pretty severe and I think it may be too much for the pan of the kit. My question is: Can I raise drain to the heigth need by adding a flange or something and then using self-leveling cement around it to bring that portion of the floor up? I am trying to avoid having to break up the concrete floor and reset a new drain.
