I need help trying to figure out what to do. I want to insert a shower in my basement. I have a drain already in the floor for a shower. Its 2inches and sticks out of the floor about 3 to 4 inches. I had a plummer come out and tell me that he would cut this down and cut into the concrete to make the shower install fit. Can someone explain what he means so I can possibly do this myself? As the plummer states the drain is already vented? What do I do?
Thank you,
