What size pipe are you talking about, most bathroom sink and tub drains would be galvanized not cast.

Yes you can replace it with PVC. We don't have enough of information do you have basement or a crawlspace, if it is a crawlspace how big it is?

am going to tear out the floor and wall to do it right .and start over.
