Of the 98 locker rooms I’ve visited, I only remember three that feature what I call a Shower SuiteTM which provides complete privacy when showering and afterwards for when toweling off, drying/combing one’s hair, brushing one’s teeth and shaving.
The Shower SuiteTM takes the locker room experience to the next level, although on very busy days there could be a wait. If space and budget permits, I recommend an additional sink grooming area for those who won’t be using the showers. Other nice features are to have separate sinks for the bathroom area being located away from the shower area as well.
Belfair in Bluffton, SC features all of the above.
