This glass and marble mosaic tile is a modern decor element with a sleek pattern and a touch of gleam. It combines the sophisticated beauty of white marble with the luminous appeal of grey glass tile for a visually appealing surface. The elegantly classic combination of white and grey creates a soft contrast that results in a clean and airy look. Preferred for its long linear shape pattern, its vertical installations can create walls with a waterfall effect that's perfect for the shower or accent wall. Its mesh backing allows tile to be cut for smaller uses, such as a tile band for the kitchen backsplash, shower head or niche design. The glass mosaic tile is an attractive, easy to clean and heat-resistant solution for a fireplace surround, vanity backsplash or light-traffic floor designs
