Both bathrooms in our house share a wall, in between the showers. The guest bath has two switches, one to an overhead light, one to an exhaust fan. I'd like to add a shower light in this bath and set it up so to have the shower light on, the fan must be on as well. The kids never remember to use the fan as it is now. I'd also like the fan to be on anytime the regular light is switched on, to use the fan as a sound deadener, as this bath also shares a wall with the living room. Can an exhaust fan be set to receive power from two different switches?
The master bath has only an overhead light, I'd like to add a fan to this bath. As the two are so closely located, is it possible to add the master bath fan, and somehow attach it to the vent opening that goes through the roof for the guest bath fan, so we don't have to have two openings close together?
I wouldn't be doing any of this work myself, would hire an electrician to install the light and the fan, but would prefer not to have to have another hole put in the roof if it's not necessary. Just wondering if these ideas are possible before getting the electrician involved.
