A fiberglass tub's affordability is one of its main advantages. Compared to tub options made of metal such as brass, copper and cast iron, fiberglass is an extremely budget-friendly tub material. It is also less costly than tubs made of stone such as soapstone, granite, marble and onyx, and solid surface materials.

The composite material is usually the tub’s infrastructure, and an enamel covers the material. The goal with composite is to create a tub that’s durable and can keep in heat like cast iron, but lower weight.
