Fiberglass is reinforced plastic finished with a polyester gel coat. This gel coating creates the smooth and glossy look desired for the shower. Fiber glass is one of the more affordable options for showers making it a popular choice. The smooth and glossy texture of this surface is slick when dry and very slippery when wet. Since the floor of a shower is constantly going to be wet it is very important to consider treating the shower floors to make them slip resistant. The shower can be a very dangerous place. According the Centers for Disease Control and Prevention (CDC) approximately 266,000 people are injured in the bathtub or shower a year in the US. These statistics prove that slipping is a very big concern in the shower.
