How to care for and restore a cast iron bath tub
Timeless and elegant, cast iron bath tubs may be though of as old-fashioned, but a cast iron bathroom is one of the hottest decorating trends, especially the new acrylic reproduction models that look good without the weight factor.
Manufactured from casting iron - which gives these tubs their name - modern cast iron, and even older vintage tubs, are finished with an enamel coating that makes them extremely durable.
Manufacturing process
The name of these tubs refers to the manufacturing process, where molten iron is cast into a mould shape and then cooled before being coated with sprayed-on and baked enamel. The end result in a glossy finish that retains its properties for a long time.
The sheer weight of a cast iron bath tub is obviously one of the factors for the durability of these tubs; limiting damage like cracks, dents, and chips. Cast iron tubs are retain heat for longer than modern acrylic tubs - more time to relax and soak away the stresses of the day! However, it is the weight of a cast iron bath tubs that makes them impractical for many homes, where acrylic reproduction tubs offer a more functional solution.
Styles
Both original cast -iron and acrylic reproduction bath tubs are available in a variety of styles:
Classic Roll Rim/Top or Flat Rim –
The original and most sort after type of claw foot tub, from the period 1890 and 1940.
One of the ends of the tub is flat, which is usually the location of the taps, while the other is round.
Double Ended – With rounded ends, taps installed at a mid-point between either side, or on one side and a drain located in the centre, this style allows for more flexibility in terms of bathing position options.
Slipper – As the name suggests, the overall shape is comparable to that of a slipper, with one end raised and sloped to provide back and head support, making for more comfortable lounging.
Pedestal / Skirted – This type actually does not have claw feet, and rather sits on a skirt or pedestal that encircles the entire base. Stylistically, they can fall under the art deco category.
Double Slipper – Both ends are raised and rounded, though one side is slightly more flat than the other.
Typically, drains are located in the centre, and taps are mounted on the side.
