Bathroom GFCI 15 or 20amp?

Friends house is 100 years old. Says its legal to just switch out the old outlet and put in a 15 amp gfci. I thought all bathroom outlets must be 20 amp Gfci protected. So who is right?

The bathroom duplex receptacle does not need to have the 20 amp slot configuration. The circuit should be a 20 amp to satisfy recent NEC codes.

It is acceptable to replace any existing standard receptacle with a GFI-type using the existing wiring . The requirement for a 20 amp Branch Circuit to supply bathroom GFI receptacles applies only when the wiring in the B-R is a new installation.

If the wiring is left as-is you can stick with the existing grandfathered 15A. If this is a renovation, then it must be upgraded to a 20A circuit according to modern code.

If you are expecting a inspector to show up, you might want to label it "No Equipment Ground." NEC 406.4(3)(B)

Assuming that its 12/2 or 14/2 non ground wire.. If the 100 year old house has had a service upgrade and the wire has a ground all is good. Then again if its 100 years old and all original Im not sure it even has to have a GFCI period do it? Its still grandfathered in still... Although its a good idea to have on.Beer 4U2

Also NEC 210.11(3)
It basically says it should be a 20amp circuit but it does list exceptions.. NEC 210.23(A)(1) and (A)(2) which would allow a 15amp receptacle from what I gather in a single bathroom on a 20amp circuit which is by code. It says nothing about a 20amp receptacle, just the circuit.
