What is the difference between acrylic and fiberglass, cast iron, steel, synthetic (like limestone) tubs?
Acrylic is a solid sheet material that is heated and vacuum formed to the desired shape. It is then reinforced at the back with fiberglass to give it strength. It is a higher-end material, very durable and super easy to clean. Fiberglass is a material that adheres to a mold and then a gelcoat finish is sprayed onto it. The most common material used in tubs and showers and is the most economical. Cast iron tubs are forged and the finish is applied in powder form while the tub is hot causing the finish to melt onto the cast iron. Synthetic tubs are molded and then a gelcoat finish is applied like the fiberglass tubs.
