I am doing a renovation job with 3 bathrooms. For each bathroom can I just run a 20 amp circuit to each bathroom and use that same circuit for the receptacles and the lighting. Ideally I would want to have the receptacles and lighting circuits seperated, but linking the 3 bathroom circuits will not be easy (although it is T&M). If there is a code section that I am overlooking, please clue me in.
 
You can use one 20 amp circuit for all the gfi's in all three bathrooms and the lighting on another circuit. Or you can put the lights and outlets on the same circuit in one bath but it cannot go to any other bathroom. 210.11 (c) 3.

Thanks. I was planning on just running a 20 amp circuit to each individual bathroom (3 circuits total) for receptacles, lights, and exhaust fan. Could you let me in on what code section this would fall under for future reference?
 
You can use 1 single 20A home run to supply everything in a (single)residential bathroom.
....unless...
Any one "fastened in place utilization equipment" (like a heat/light/vent unit) draws more than 10 amps
....and/or...
Any "plug and cord connected utilization equipment" draws more than 16A.
Also....The circuit can't supply anything outside that bathroom.

See 210.11(C)(3) (as posted by cavie) and 210.23(A)(1) and (2)

I haven't had to wire in one of those exhaust fans with a built in heater for quite a number of decades, due to geographical location. I haven't got a clue as to what amperage they draw on avarage. Just curious, anybody ?

As with most appliances, HVAC, etc., you have to get the supplier to provide you with the data when you need it for load calcs and rough-in.
