We just had a four-function fan installed and my husband later put a timer just on the fan portion of the unit. You can essentially wire any of them together or separately if they are all the same amps. The only time you cannot wire them together is when one of them draws more amps, like a heater. If you want the light to come on with the fan, then you simply have to wire them together on the same switch.

Because we don't know your particular setup and how the power is wired to that room, it is best you bring in an electrician or someone that is knowledgeable about wiring.

I have a switch for the vanity light, one for the shower light, a timer to twist for the exhaust fan (these three all share one switchplate)and a thermostat for the heated floor. I guess if you want to double up you could put the vanity and shower lights together.

chimmy, one option you may want to consider is a Lutron switch that houses two switches in one. In particular, they make one with a dimmer on top (for the shower light, perhaps) and a countdown timer below (for the fan).

I've recently put this switch (Lutron part #MA-L3T251) in both of the bathrooms we've remodeled. I like having the separate control over the light and the fan, and having the fan stay on after a shower but turn itself off. It comes in the full range of Lutron's series of colors.

Thanks for all your suggestions. That switch, Jacobse, is kind of what I need. But is it possible to have one switch/timer for the recessed light and fan such that once you decide to shower and turn on the recessed light over the shower, the fan comes on too? Thanks again.

The only way I know of to have both the fan and light to come on together would be to wire them together to one switch or timer. I find it very easy with the stacked switch to hit both buttons when I enter the bathroom; I turn off the light when I'm done in the shower, and the fan turns itself off after an hour (or whatever time you set it to).

If you wired them together to a single switch, then you wouldn't run the fan after the shower, which is good for drawing moisture out of the room. If you wired them together to a single timer, then they'd both be on for an hour until the timer shuts them off, wasting power on the light for an hour every day. (Depending who's using the bathroom, you might also have someone turn off the light, not realizing it's also turning off the fan.)

I'm sure someone with an electronics background could build a box you could stash where the wires run in the attic with a relay that turns the light on when the fan goes on (or visa versa), but doesn't turn both off when the switch goes off for either one. But I'm not aware of a readily-available commercial switch that does this.
