Our basement is roughed-in for a bathroom. I'm going to install a Swanstone shower base. The shower drain is a 4" pipe rising several inches above the floor. I'm planning on cutting it down with a cutting wheel on an angle grinder. My question is how much stump should I leave?

Also, how should I fit the 2 inch drain from the shower base into the 4" pipe - can I simply let the 2 inch drain drop into the 4" pipe without any extra fittings?

Is there a p-trap in this 4" drain pipe? If there is you can cut it off flush. You will have to find a bushing to fit inside the 4" pipe to adapt to the 2".

If there isn't a p-trap you will have to break out the concrete around the drain, cut it off below grade, install the bushing and p-trap.

Dear Chart,
First off, is the "stub" cast iron or PVC? Second, if it is 4", than I believe strongly that it was meant for a commode, hence, no trap. Is it vented? Do you have enough room on your ceiling height to jump up the base about 6"? Many many questions. They are all, however, pertinent. More info will help you more.

Thanks to all for the responses. There is a p-trap below the floor and the cast-iron pipes are vented - the bathroom was stubbed-in by a plumbing sub-contractor for a sink, toilet and shower during construction about a year ago. I just didn't know how much, if any, of the pipe to leave above ground. Was able to confirm through trial and error that the PVC drain connected to the bottom of the shower base will just drop into the cast iron pipe, and the shower base fitting will fit snug into the pipe.

Thanks again. --C
