They really look good on the walls to the left and right of the bathroom counter, a real upgrade from the old oak towel ring. Mounting at just one end of the towel bar could be a problem, though, even with two screws. I used pop-toggles in our drywall, but with a wobbly person in the house who may reach out to a towel bar for support, I may have to re-fasten them into wall studs to keep them in  place.
