I am buying a new house that has the washer and dryer located on the main floor, but I want to move it into the unfinished basement (as well as add a laundry tub).

There is a rough in for a bathroom directly below where the washer and dryer are currently located, and I'd like to move the washer and dryer next to that rough in (so that the washer and dryer would be in the room next to the bathroom).

Is it possible to use the rough in that exists for the bathroom rough in, or to tap into the existing washer drainage to drain the washer? Or would I have to tear up the concrete to create a new drain?
