Originally, tubs were made of cast iron then covered with enamel. For economic purposes and manufacturing time constraints, fiberglass tubs are now the primary alternate for replacing old tubs.
Types of Fiberglass
Fiberglass tubs are made from the same material that many car and boat manufacturers use. There are 2 main types of fiberglass tubs. Acrylic coated fiberglass is durable if the acrylic is thick enough to withstand wear and tear. Acrylic-coated fiberglass tubs can crack easily if the grade and thickness of the acrylic is substandard. The best acrylic fiberglass tubs are backed with a composite material for added support and strength. Gel-coated fiberglass is covered with liquid gel at the appropriate temperature. It makes the finished product highly durable. Gel-coated fiberglass is easy to repair and maintain.
Advantages of Fiberglass Tubs
Fiberglass tubs are very cost efficient and inexpensive to maintain. If you treat your fiberglass tub as you would the hull of a boat or certain types of cars, it should retain the same shine as on the day that you installed it. Follow the manufacturer’s instructions for cleaning a fiberglass tub. It has even been suggested to wax the sides of a fiberglass tub to maintain the shine.
