There are a variety of different types of tiles used in showers. Glass tiles are a very attractive but expensive option. Ceramic tile is an affordable and durable material that is commonly used in bathrooms. This clay and mineral mixture comes in a wide variety of shapes, colors and sizes. Porcelain tiles are fired at extremely high temperatures making it a very strong and durable tile option. Some people want a more rustic look for their bathroom and choose to use stone tiles. Travertine and tumbled marble are some popular examples. These tiles may have different finishes but the shower tile floor is a place that will be constantly wet and this makes it very easy place to slip and fall. It is very important to treat these tiles with to make them slip resistant. According to the Centers for Disease Control and Prevention (CDC) approximately 266,000 people are injured in the bathtub or shower a year in the US.
