I am renovating a bathroom, and I'd like to put a pedestal sink in, instead of a full sized vanity. The primary issue is I would have to move the drain pipe, it is a cast iron drain pipe that is currently on the wrong side of an interior wall stud.

I have full access to the wall in the bathroom, so I can get at pretty much any part of the piping, but I'm not sure how to handle the stud and changing the iron piping.

Here's a picture of the way it looks now (what pictures would help?)

The bit of PVC you see sticking out immediately connects to the aforementioned cast iron pipe, it broke while I was trying to remove it.

Here's some more pictures: enter image description here enter image description here

The stud you would use a hole bit that is the same size as your piping to cut a circular hole. You can pick up these bits at big box or a place like Harbor Freight in the US.

You do need to make sure that the stud is not load bearing! If it is or could be we need more info and pictures.

It really looks like you have PVC but we can't see everything. If you need to go from PVC to cast iron use a coupling.

Oh yes, I'll add a quick note about that in the post, but basically it had a PVC pipe sticking out of it (that I accidentally broke while removing), but it's cast iron immediately after the lathing. –  Dugan Aug 21 '13 at 22:29
    
Just cut the iron so that it is flat going same direction as wall, put on a coupling and route your pvc through a hole you need to drill. –  DMoore Aug 22 '13 at 0:59

Also the second picture is your vent. You will add a T to your PVC in the wall to reach the vent. –  DMoore Aug 22 '13 at 3:55
