The electrical code in my area requires using GFCI outlet for outlets within a certain distance of water source. I don't remember precisely the distance (and it likely vary a bit by jurisdiciton), but i know that in my bathroom, there's nowhere beyond it.
In order to use that sort of outlet in a bathroom like mine, it would have to have GFCI protection as well as USB, be a second outlet wired to the GFCI protected terminal of a GFCI outlet, or be wired to a circuit breaker with GFCI protection built in, in the electrical panel.
Is that a fart joke?
