You can expect a bathroom medicine cabinet to last 30 years, and sometimes much longer. Like other cabinets in the bathroom, it is likely to be replaced while still functional, but dated and a little battered, as as part of a bathroom remodeling.
Here’s a bar graph that compares the life expectancy of a medicine cabinet to other types of storage.
