Glass tiles are a common choice for bathrooms and kitchens today because they're easily recycled and come in a wide variety of colors and finishes. Mosaic tiles — usually shaped in rectangles, squares, or "pennies" — have become increasingly popular. These glossy mosaic tiles work well on this bathroom floor because they're easy to clean and provide traction during your post-shower dry down. Remember that a glossy floor tile isn't the same as a glossy wall tile — before buying, explain to an in-store expert where your tile will be installed. Floor tile has to be safe to walk on, so you want to make sure that the texture and strength of the tile is correct.
