Mirror, On The Wall - It's got nothing to do with vanity. Hanging a mirror on the wall of your home gym will allow you to check your form as you lift weights, so you can keep a proper posture. A mirror also can brighten up a small space, and, of course, help you track your progress.
A small bedroom turned into closet/dressing room. This is a great example of an AFFORDABLE/REALISTIC version of a dressing room for a young couple....man cave, meet woman cave. I'd have a tv and wine cooler in here!
