I am planning the development of my basement. I plan on installing a corner style shower base. My house has the plumbing roughed in. I asked for a 3-piece rough-in but I think I got a 2-piece? There is one pipe protruding from the concrete floor (which I assume is for the toilet) and there is one pipe protruding from the unfinished wall connected to vent stack (which I assume is for the sink drain). Can I connect my shower drain to the vent stack as opposed to breaking apart the concrete to connect to the below grade drain? I understand that I would need to raise the shower base to allow for the P-trap from the shower drain. Or is there a better alternative?
