410.4(A) addresses luminiares in wet and damp locations. The location that you describe is a damp one, and therefore the fixture must be listed as such. The only way (that I'm aware of) to obtain this is with a shower lens.

Ryan, a saleman came to my office today with a fixture...(progress lighting) he stated the fixture is listed for wet locations (no cover required) I have always installed covers over shower lights.
I would ask to see the UL information on it before I put one up. Oh, by the way, it would be a good idea to keep some copies of that info on the job and in the truck, because I'm sure your inspector will ask for it.....I would!
I looked up a few reccessed light fixtures on line, and all the ones I found were approved for damp areas with out a cover. Before I found this I was of the opinion that outdoor reccessed lights had to have closed covers. I've changed my mind. I think the shower could be a wet location if the ceiling/light fixture is low enough to have water splash into it. Then according to 410.4 it would require a closed trim
I would look at the configuration of the shower. Many of the smaller shower stalls will have splashing water directed into any fixture inside the stall. I would require a watertight fixture cover for these conditions of use. If, however, there is no way for water to be directed into the fixture, then a fixture approved for damp locations would be approved.
c'mon guys any shower should have a lense that is water tight. all it would take is one fool tossing water in the air to create an electrifiing experience.
