I'm removing a built-in cabinet in my master bath, and there is no receptacle on this short wall where the cabinet exists. I want to add one, once the cabinet is gone, and there is a 15-amp receptable in the bedroom exactly opposite where I want to locate the new bathroom receptacle. So, I would like to simply pick up power from the existing outlet.

My question naturally is this:
Can I run the 14/2 wire and install a 15-amp GFCI to this existing bedroom circuit or will this violate code?

 

Yes, this would be a code violation as bathrooms must be on a 20 amp circuit and shall have no other outlets except bathrooms. Exception is, if you run a 20 amp circuit to ONE bathroom, you may include lights, etc. Merry Christmas

 

Yes, you need a dedicated, gfi protected 20a circut for the bathroom. Lights and fans are permitted to be on that circut, however, I usually like to do them sepereately, usually on the lighting circut for that floor.
