Recessed Light with Exhaust Fan above the Shower

Hi All,

I am remodeling my bathroom and I am adding a fan/light combo above the tub. The manual says it should be gfci protected.

There is gfci receptacle that is running on the 20a circuit already in place. I plan to run a 20a wire from the GFCI outlet to a switch and continue to the wiring on to the light/fan. Below is a drawing of my plan.

Please let me know if this circuit is correct and provides GFCI protection or should I do something differently.

Thank you in advance for your responses.

At the switch box neutrals are connected only to each other not the switch if that is a standard switch.

If this circuit serves other bathroom receptacles you cannot add the light to the circuit.

Thank you for the responses.

The circuit does not serve other receptacles. It is currently terminated at the GFCI outlet.

Yes, that is correct. With a 3-conductor cable between switch and fan/light and a duplex switch you could control the fan and light separately.

The power from the GFCI is connected via one wire to the screws on your picture. Note the buss between the screws making both hot at the same time. Eliminate the wire from those screws to the fixture. Your three wire cable will have your neutral, red and black. The red is connected to one screw on the other side of the switch and the black is connected to the other screw, thereby allowing separate control of the fan and the light.
