There is an electrical plate over the medicine cabinet in our half bath. However, the wires do not not appear to be connected to any of the switches for the room. I'm guessing that the switch was on a medicine cabinet/vanity that had a switch attached (are these even legal these days?). Connecting a light to the switches located outside the bathroom would require breaking into the wall. Does anyone know what the code says(I'm in MA but a general idea about codes will be helpful) about installing a switch in the bathroom? The easiest way would be to drop the wires behind the med. cabinet wall to a switch right below, but that would place the switch on the wall over the sink and that doesn't sound safe. Electrician is away and I'm wondering if it's even worth asking for an estimate. TIA.
