These convenient accessories were popular in the Fifties and Sixties. A company called Hall-Mack offered an entire collection of bathroom built-ins to make your modern life easier. Our house also has a couple of their classic Tow'lescope retractable towel bars (which look like a horizontal radio antenna when extended over the sink). The most rare of all though is the fold-down bathroom scales!
But I digress.
