I have a basement bathroom that I need to redo the shower stall. The issue I have is the original drain is a 4 inch cast iron pipe flush with the floor. The drain from the original shower stall pan was a pipe that had a 4 inch diameter top that fed down into the 90 degree cast iron trap. How can I still use it and get the best/correct 2 inch drain so I can build a shower pain? I have added a picture of the hole and original drain from the stall.
