I am remodeling a small bathroom attached to a guest bedroom and I am wondering if I can wire the whole thing on one branch circuit.
The bathroom is divided into two parts:
a 5x5 room, behind a door, with just a toilet and a shower. This part has an overhead LED light and a wall-mounted fan.
just outside the 5x5 room, a sink with a mirror. This part has two wall-mounted lamps, one on each side of the mirror, and a GFCI receptacle.
Can all of this be wired safely and code-compliant on one circuit? Would I use 12 AWG wire throughout, and a GFCI breaker at the panel?
