Bathroom Outlet Wiring

[jeff48356]

Consider a colonial house with two full bathrooms upstairs -- one main bath and one with a master bedroom. Since bathroom outlets need to be on a separate 20-amp circuit, would each bath typically have its own circuit for the outlets? Or could the outlets in both bathrooms be wired to the same 20-amp circuit (with no lights or anything else)? If the latter scenario is allowed, would it be advisable? If someone was using a hair dryer in both bathrooms at the same time, it would trip the breaker.

I never connect my bath lights to the receptacles. You certainly can use one 20 amp cir and connect all the bath receptacles in the house however I tend to have a separate cir. for the master and then the kids bath, guest bath & half baths together on the other. Whatever works.

I hate complaints that my kids are drying their hair and when I turn on my dryer the breaker pops. Remember some of those units draw upward of 1500 watts.

IF the circuit serves only one bathroom, it can also have bathroom lights, fan, etc. on it.
If the circuit is the required 20A receptacle circuit and it serves more than one bathroom it cannot have anything but receptacles on it. Not quite sure what the motivation for that is.

If you serve two bathrooms, then I would avoid using a GFCI receptacle in one bathroom to provide feed-through protection to the receptacles in the other bath. Too confusing.
