Bathroom light and fan combo safety and wiriing
NEC 2014 - 410.10 (D) outlaws certain types of luminaires in the bathtub and shower areas, but your fan/light combo is not included in that list. That bathtub/shower area, by the way is defined as 3-feet horizontal and 8-feet vertical from the top of the bathtub rim or shower stall threshold. So, with 11-foot ceilings you've got a lot of latitude (more than most people are blessed with) for hanging fixtures in this area. Probably a good idea if your unit is marked suitable for use in wet or damp locations. GFCI protection for luminaires in bathtub/shower is only required where installation instructions specify it. And, I believe, most manufacturers of the fan/light combo's I have installed do call for it. By the way, I just double checked and the code was the same in NEC 2011 and hasn't changed in the 2017.
