Irregular Subway Tiles are a popular choice for tile kitchen backsplashes because they are relatively inexpensive and easy to cut and install. It is a popular look but it has also stood the test of time. Subway tiles have been used for centuries to tile kitchens, bathrooms, hospitals, subways, and restaurants. Today we use them mostly on kitchen backsplashes, but subway tiles are also popular in showers and tub areas. Most subway tiles are made out of ceramic, and they are come in various sizes. 3x6,4x8,2x10, and 3x12 are the most common sizes used today. Subway tiles can also be made out of porcelain, but they are almost always ceramic. Ceramic tiles are easier to install and grout, because they are lighter and have a more absorptive clay body with a glazed surface.
Grouting with a sanded grout like customs prism, laticrete permacolor, or mapei ultracolor with give the subway tiles a hand crafted look, where using a non-sanded grout like customs Polyblend non-sanded will give the tiles a more sterile, commercial look. A good sanded grout job can make an ok install look great!
