It is recommended to drill the hole directly from the back of the water heater's wire box, lead the pipe out of the bathroom, smash the ditch on the latex paint wall, lower the pipe, connect it to the nearest socket in the room and connect the grounding wire.

Metal panels without electrical equipment do not need to be grounded.
