I've already opened the wall completely where the old vanity was.  Might 
as well as I have to plumb the back wall and unplumb the side wall.

Actually, I meant to have a new 1 1/14 vent turn and meet the existing 
stack. Not comfortable drilling any larger than 1 1/4" But I guess I 
could down size the waste line to 1 1/4".

There is one thing I neglected to mention

It's a basement garage ceiling.  So not a biggie.  Also not too 
complicated, my shower on the second floor has a trap in the floor which 
I've replaced.  Still my preferred method as the waste pipe would be 
completely hidden.  Just don't know if it is legal or that there could 
be problems like retrieving a lost ring from the trap.
