I don't exactly know what you are saying, but yes you can wire an exhaust
fan to the circuit feeding the light, although if the fan is above the
tub-shower, it will have to be U.L. listed for that purpose and protected by
I meant that I want to avoid having to fish wires for a separate switch
for the fan -- just have the fan run whenever the light for the shower
cubicle is on.
The existing (enclosed) light fitting is not on a GFCI-protected circuit
-- it's an older house -- but the fan will be outside the shower cubicle.
I'm planning to upgrade the electrical system later on and will split
some circuits, putting all the bathroom ones on a GFCI.

A lot of people think the steam from their showers is different from any
other steam. If the fan didn't go on with the light in hotel bathrooms, the
wallpaper would be falling off in chunks and the maids would spend half
their time removing mildew.
I've now hooked it up, and it's so quiet that you'd hardly know it's on.
It's a GE that's claimed to be super-quiet, and indeed it is -- nothing
at all like some of the motel bathroom fans I've encountered (which
probably had clapped-out bearings and were ready for the dumpster).

Are these things necessarily recessed in the ceiling? What's the
effectiveness? Don't they have to exhaust to outside to effectively
decrease the humidity in the bathroom?

I agree that the noise is the issue. In my mother's apartment, I put
a pull chain switch in both of the fans so she could turn off the fan
when she was putting on makeup or whatever. This is the one change I
didn't undo when we returned the apartment to the people who run it.
In my house, when I put a light above the mirror (it only had a light
in the ceiling), I interrupted the wire to the fan and put a
push-button swtich in the new light housing, to control the fan.
Anotehr one to control the wall light. I don't take steamy showers**
but I do want to run the fan sometimes to get rid of fumes from
**But yes, my steam is better than anyone else's steam. My dirt is
better than anyone else's dirt too. That's just the way it is.

That was my thinking. But the OP suggested (I think) that the light is
for the shower cubicle, not just the bathroom as a whole. In that case,
it may make sense. Also, he seems to be saying the bathroom is
eventually going to be rewired, so he can do things differently then.
