Great use of under sink space. For bathroom under sink space/ use same idea using uniform Spray bottles filled and labeled/ shampoo/ conditioner/lotion/etc. keeps frequently used items out of the way/ easily accessible for use/ just unscrew sprayer.
This is kind of the look I'm wanting for kitchen pantry. Use glass and wire storage. Also like the idea of putting maybe contact paper as wallpaper to add texture and design to wall. Add rope lights to inside of closet.
