The aesthetic appeal of a glass floor tile is twofold: Covering part of the floor in a thin layer of glass creates the illusion of depth and, if tinted, a lovely stained-glass effect. Installed properly, this type of tile holds up well—just be sure to select textured glass to prevent slips. Small glass tiles with lots of grout joints are also slip-resistant. With these tips in mind, consider customizing a shower floor(perhaps even up the sides) with tiny glass tile squares to create a showy feature in the bathroom.
Note: When buying ceramic, porcelain, or glass tile, be sure it’s rated for use on floors. Choose ceramic tile with a grade of 1 or 2 for floors. Ceramic tile also comes with a coefficient of friction (COF). For safety, choose one rated .50 or greater. The Porcelain Enamel Institute (PEI) rating system counts the other way; opt for tiles that are at least PEI III.
