I'm looking in the 2002 NEC: 410.4 (D) refers to hanging fixtures.
Lately, we've seen a lot of housing tract plans with recessed can fixtures over showers and tubs. We have universally required fixtures "suitable for wet location", per 410.4(A).
Shower water off the top of my head can easily hit the 8 foot ceiling in my shower, so it seems to be an easy call. What say you?
