I use a book bag type day pack to carry my stuff to the shower. The showers are very well ventilated and air conditioned and the comfort station interior does not feel "steamy". My tent is too short to stand up in, so I even change clothes in the morning in one of the shower stalls.
Each shower stall has a hard locking stall door with a front portion with a bench, and multiple hooks. Then behind a curtain is the actual shower portion.
I take my shower at night, so don't use a blow dryer, but (in the women's at least), they have a large mirror, with a shelf and several plugs for curling irons, blow dryers, etc. This area is next to the sinks, so that keeps the sinks free for those brushing teeth, etc.
