ECN Forum Forums Code Related Discussion NEC & other Code issues Exhaust fan in shower area??

Is an exhaust fan permitted in the shower? My customer has a shower that is totally separated by a wall and shower door from the bathroom area.
Also I assume I can put a recess light with a gasket in the shower. Does it have to be on GFI circuit. I'm only looking at the 99 code and do not have the newer ones available right now. Thanks..
