OK -- just run a new circuit to the bath for one or two outlets. Leave everything else alone. Houses of that age didn't have much in the way of bath outlets normally anyways.
Breaker panel up to attic, down into bathroom wall, out of bathroom wall into basement, then to bedroom outlets. Hence why I was just looking at tying in a new piece of 12/2 romex for the bedroom.
Breaker panel is in basement. Would abandon the run from the bathroom wall to the basement.
At some point I will probably replace the entire run when I remodel the bath. Bring the circuit in from the basement instead of the attic as the wall design is cinder block with firing strips and plaster wall. Don't like the wire runs sitting loose between the two.
