Enamel-coated cast iron is the most durable bathtub material, offering a rock-solid feeling of strength with a rich, glossy surface and vivid colors. It is a premiere finish and is usually the most expensive. The word "cast" simply identified the method used to produce the finished product, and not to describe the material itself. The casting method involves pouring molten or liquid iron into a mold, which defines the shape of the finished product. The thickness of the enamel makes its surface resistant to acids and provides outstanding protection against chipping, scratches and dents. It is very impact-resistant and displays the richest, most highly polished finish of all bath materials. Cast iron's combination of real molten iron and extra-thick enamel provides extraordinary beauty. Fired at temperatures much higher than possible with enameled steel products, the cast iron surface is "fire polished" to obtain its vivid color and deep gloss. Its high-gloss surface resists damage and its structural density protects against dents and dings that can cause porcelain-on-steel tubs to chip. Cast iron reduces vibration and noise while helping water to stay warm longer. |
