Mosaic tiles are usually found in 2x2 in squares but they are available in a variety of shapes. They can be made from glass or porcelain. Mosaic tiles are used most frequently in kitchens, bathrooms and entryways. Mosaics are used for their beauty and their ability to create designs that can not be created with larger tiles. The ability to customize floor designs by mixing and matching the tiles gives an artistic flair to Mosaic tiles. Mosaic tiles are very affordable, have high water resistance and are easy to clean. One of the major downfalls to these aesthetically pleasing tiles is how slippery they become when wet. Mosaic tiles are commonly used in areas (kitchens and bathrooms) where liquid spills are a likely to occur.
