For an elegant look in your bathroom, try using cultured marble. It's easy to work with, because it's made of real marble dust mixed with plastic resins. It's lighter in weight than real marble and less expensive, too. To cut, use a rotary saw with a masonry blade and smooth the edges with sandpaper. Use a panel adhesive to attach the sheets to the wall and brace them firmly overnight. Remember to use safety glasses and a respirator when working with cultured marble.
