I purchased this mirror/medicine cabinet for my parents small master bathroom. The new vanity max width was 30 inches. I wanted a mirror to fit that width exactly to provide a cabinet to provide as much storage space as possible since I'd taken away their counter top. This cabinet was the perfect solution! My parents (70yr old) love it. The staggered shelves at different heights work, the enormous height provide more than enough space for everything and mirror on the inside is an added bonus.
