In the 1940’s and 50’s Kohler, American Standard and other tub companies came out with cast iron tubs that had multiple functions. You could soak for hours or shower for a few minutes. You could put your shampoo bottles, bubble bath, scrubbing brush and anything else you wanted on the handy built in shelf. The tub came in pretty colours, like pastel green, blue, yellow and of course, pink.
The tub had many names… the Cinderella, the Princess, the Mayflower and the list goes on.
