As Micheal Says…However if you would really like a code interp. from someone who gives them alot…here you go.
Art. 100 gives us a defintion of a bathroom and 210.8, 210.11©(3) and 210.52(D) tell us alot about the bathroom circuit.
If the following apply it is part of the bathroom -
a.) On the dedicated circuit and designed to be associated with the bathroom and meeting 210.52(D)-Its the bathroom
b). If the circuit required in 210.11©(3) is installed for the purpose of 210.52(D) then it is the bathroom
c.) If an additional 15/20A circuit is installed because someone wants to and it is inside the bathroom and services the bathroom, facing into the bathroom location then it is part of the bathroom.
Now fall back to 210.8(a)(1) - If in your judgement it is in the bathroom, facing the bathroom and is intended to be part of the bathroom then it is part of the bathroom and would be on GFCI.
In regards to the phantom 6’ rule in bathrooms for dwellings ( yes, Phantom rule I guess )…It could be just as unsafe at 7’ as the average arm span is near 6’ anyway…dont underestimate what ignorance can lead to. if it is in the bathroom make a statement it needs to be on GFCI or if older construction make a safety advice enhancement and help educate them.
FYI- I give them alot…does not mean I am always right when I give them
