HIGH GLOSS ACRYLIC SURFACE
Why we use acrylic.
If you go back to the history in the materials that were used for making a tub, it has improved immensely. Tubs were first made of heavy cast iron and then subsequently of steel. The problem with cast iron and steel is that when you fill a tub with hot water, the materials are heated up first, and all of the heat is taken out of the water. Today, bathtubs are made out of acrylic, which is a pliable plastic that is very strong reinforced with fiberglass and resin. Acrylic with its fiberglass backing is an insulator, so when you put hot water in your tub, it will stay hot.
