"Luminaires located within the actual outside dimension of the bathtub or shower to a height of 2.5 m (8 ft) vertically from the top of the bathtub rim or shower threshold shall be marked for damp locations, or marked for wet locations where subject to shower spray."
To a height of 8' takes care of the tall ceilings. However, IF there is a chance the shower could spray up, then...all bets are off, and it's wet.
