Friends of ours also moved their medicine cabinet for the same reason. The double stick tape damaged the wallpaper in the process, and they also hung a large mirror over their oops. Looks great!
Speaking of RV mirrors, we spotted two mirror/cabinet installments when RV shopping that left us scratching our heads. In one unit, the cabinet was attached so high, I had to stand on tiptoes to see myself or reach anything. The other was centered on the wall rather than over the sink. Awkward.
These RV designers need to do a "real people" check on their designs.
