Material and structure: As obviously indicated by the name, glass tiles are made of glass! Finishing texture: contrary to general perception, not all the glass tiles are glossy. They actually come in a high variety of colors, patterns, shininess and surface textures. *ATTENTION*: Glass tiles are often used in spas, pools, bathrooms, and kitchens. They are mostly used for walls. However, there is a specific type of glass tile that is produced for floor application. Durability: Although glass tiles are usually not as durable as other types of tiles, still as long as they are not under pressure they can last for decades. Specific advantage: resistant to water and humidity makes it a good choice for bathroom and kitchen. Being available in a wide variety of colors, shininess, patterns, and finishes, glass tile is decorative and functional at the same time. Installation: Installation of glass tile is tricky and so we highly recommend that you hire a professional to do that. Weaknesses and limitation: Glass tiles are not as durable as other types of tiles. They usually break relatively easily. Considering the usually-high cost, for sure not a DIY project. Cost: 5 to 40$ per sqft.
