How to Wire a Switch for a Bathroom Shower Light and Exhaust Fan – The wiring leads may be to the other device so that both the shower light and the fan are on the same switch.

Optional Shower Light Switch Wiring
Electrical Question: I want to wire a shower light and separate fan on one switch and I want to install electrical wiring for a bath tub light and the same separate fan on another switch, both switches in the same box.

Is this possible?

I would just like to be able to turn the shower light and fan together without the bath light coming on and vise versa.

Thanks for your electrical wiring question Gary.

How to Wire a Switch for a Bathroom Shower Light and Exhaust Fan

If the switches are located in the same box, and they are fed from the same power source then yes, one switch can be eliminated and the switched wire may be spliced to the other remaining switch.
The wiring leads may be to the other device so that both the shower light and the fan are on the same switch.
For total separation and control for just about any switching combination a relay may be installed and the electrical wiring to control any switching scenario you wish.
Each relay may be controlled by a wall switch.
