I would like to intall a bathroom ceiling fan directly over my shower, where there is an existing light that is turned on by an adjacent light switch. I have several questions regarding this project. First, I understand the fan will have to be vented to the outside. I currently have an attic vent that will be used for this purpose, so that is not the issue. My questions are:
1) Can I use the existing wiring for the light to install the fan? If so, what color wires are what? Keep in mind this house was built in 1952. 2) I will be replacing the switch with a GFI switch. Are there GFI switches and not just outlets?
