Last night I spent a few hours wiring up the bathroom area. I had to use 12/2 NM wire because code says to in a bath. I added a GFI outlet, a fart fan (which I have to vent outside soon), a wall sconce, and a ceiling box for a pendant light. Two switches will allow me to operate the lights on one, and another switch will operate the exhaust fan. Once this is complete, I can move to the plumbing.
