Most kitchens have tile in them.  Or they have laminates or vinyl that look like tile.  I want to upgrade the tile in my kitchen so I visited an Atlanta tile store.  It was great.  They had so many different types of tile there.  They gave me samples and I was able to bring them home and match them against my current wall colors and kitchen decor.  My favorite tiles are very rustic and old looking.  I like aged decor.  Its very nice.  I have found that deep browns really give a house a warm feeling.  I plan on using brown on the floors.
