    My 2 cents : If you have no ground in your bathroom, just a black and white wire in the outlet box, You can install a Ground Fault Circuit Interruptor and connect the wires to the appropriate screws ( Line side ) . This is a perfectly acceptable method of installing a GFCI in a bathroom per the National Electrical Code.. The GFCI senses an imbalance of current of approximately 6 milli amperes, between the Hot leg and the Neutral Leg. Although a ground is preferred in a replacement installation, it is not necessary when replacing a GFCI outlet.

    I have a 3 pin socket in the bathroom.
    But then, I have 3 pin sockets in the railway room, but when I tested them there was no ground.
    Fortunately, all my transformers are two prong.

    Building codes were changed a good 40 years ago to require two wires and a ground. They also now require a GFI for bathrooms, kitchens and outdoor outlets. We have been going back to two-prong plugs for things like power tools and kitchen appliances where they are double-insulated.

    And yeah, you can get by with two wires on a GFI, but you lose the protection of a short to ground. For instance, if you plugged an electric drill into a two-wire GFI and the hot side shorted out to the case, it would not detect this since there is no ground return.
