I have what I hope to be a quick question about my shower drain height/depth below the floor. I am moving my shower drain to accommodate a larger shower pan that I am installing. This is a 2” cast iron basement floor drain that I have cut off, installed a no hub coupling, and I am ready to install the PVC pipe and p-trap. My question is, at what depth below (I’m assuming) the top of the floor do I run the PVC after it comes up off the p-trap? If it depends on what I am installing over it, I am installing a 35” X 48” Lasco Bathware shower pan. Any help would be greatly appreciated!
