The Center for Disease control and prevention (CDC) estimates over 205,000 fatalities occurred from falling in the US between 1999-2009. Obviously the combination of water and the slick hard surface of the shower floor make the bathroom the most at risk place for injuries/deaths from slipping. Please make sure to stay safe and treat your showers to make them less slippery.
There are a variety of different options when choosing tiles for your shower. Porcelain and ceramic tiles are very popular and are available in a wide variety of colors. Glass tiles are popular also, as they can be used to create distinctive designs. Some people prefer the natural look of slate or granite. These tiles typically have a smooth surface that can be slippery, especially when wet.
Fiberglass is reinforced plastic finished with a polyester gel coat. This gel coating creates the characteristic smooth and glossy finish that makes fiberglass a popular, affordable option for showers. This smooth surface can be slippery, especially when wet.
Acrylic's high-gloss surface is a popular choice for bathtubs and showers. It is an affordable option for those that want the visual appeal of the glossy finish without the expense of a steel bathtub. Acrylic's smooth surface can be slippery, especially when wet.
