: I am installing a Mustee preformed fiberglass shower in my basement. The drain piping was roughed-in when the house was built. In the concrete floor is a 4" dia. PVC pipe cut flush with the floor surface. Of course the shower drain pipe is 2". Do I install some sort of flange to make this connection? If yes, do I sink the flange below the floor surface to allow the shower base to sit level? Thanks for the answer.

Kevin, I'm not sure what to say on this. Do you have a 3 piece bath roughed in in your basement? Do you have the 4" pipe located for the stool? Or is this the 4" pipe for the toilet? Shine a light down the pipe and make sure it is not a sleve for a 2" pipe to go into a 2" trap in the floor.If you do connect to this 4" pipe you will have to cut the floor out and install a 4x2 reducer and a 2" trap for this fixture. Without a trap you will have sewer gas in the house. Hope this helps.
