Wiring a new bathroom
Hello,
I'm in the process of finishing out a new bathroom in the basement. Framing is done, and switch boxes and outlet boxes are set. I have run a 10/2+G from the breaker box (20A) to a J-box above the ceiling (it will be accessible). There will be:
a combo fan/light
a shower light w/switch
one GFI outlet near the vanity
a second GFI outlet near the floor on another wall
a pair of vanity lights w/switch
a ceiling fixture w/switch in an adjacent closet framed in at the same time.
I have done a fair amount of electrical work in my time, mostly adding to existing circuits or in outbuildings, but this is a little more complex than I've done. I'm wondering if I could get one of you experts to save me some time and draw up a diagram showing the most efficient method (least amount of wiring)?
Incidentally, I think I should run 12 ga. to the non-vanity outlet, just in case someone in the future plugs in a high-output space heater. Good idea?
Thank you!

Do you mean you ran 12-2 to a junction box ?
If yes..... all your wiring must be in #12.
Typically in a bathroom I run a 12-2 for receptacles and a 14-2 for lights and fans.

Pjmax, thank you, now that you point that out, it makes perfect sense [head slap]. I was thinking like a plumber, running the largest size for the long run and then sizing down, but of course it doesn't work like that!
The main panel is full, but I am abandoning one circuit that formerly fed a whirlpool tub in the master bath (tub to be removed in the future), so I was planning to use that for this new bathroom.
I suppose that one solution would be to use the #10 run to power a new sub panel near the new bathroom, with two 15A breakers - one for lights and fan (#14) and one for the outlets (#12). Would that be acceptable?
