A GFCI outlet, to remain accessible, should sit within about 15 to 48 inches from the floor. If the outlet is located over an obstruction such as a cabinet, the outlet should sit lower to keep it accessible to someone who is disabled or of shorter stature.
Residential building codes do not specify a bathroom GFCI outlet must sit at a certain height. The general requirement is the outlet must be within 36 inches of water basins. An outlet should sit at each basin, or sometimes the code may specify one outlet can serve two basins if it’s located between the two basins.
