A roll top bath is a freestanding bath with edges which curve at the top, providing a distinctive rounded effect around the edge of the tub. Roll top baths are available in a wide range of styles, to satisfy various design needs, and many bath manufacturers produce them in a dizzying array of materials. It is also possible to purchase restored vintage baths, if an old-fashioned look and feel is desired.
The defining feature of the bath is the curved edge of the tub.
