Hi all, Just got a question, I am attempting to install my stand up shower(MAXX), drain, I have a 2" PVC pipe coming out from the basment concrete floor. When I put the drain on to the base of the shower and lay it on the desired location it dosen't sit flat because of the bottom part of the drain on the base sticks out farther then the base so it won't lay flat. Do I have to break up the concrete or can I just build up the shower with a 2X4 base that I could build to raise it the base up??

Thanks in advance to any replies
