The Many Beauties of Marble
Marble is a metamorphic rock - not that this bit of information is uppermost in anyone's mind when selecting marble tile flooring. But a large portion of the beauty of marble - the irregularity in colour and shade, for instance - can be attributed to this process of formation. Marble has been prized in architecture for millennia - Augustus Caesar boasted he found Rome clad in stone and left her draped in marble; and everyone is familiar with the astounding effect to which marble was used in the creation of the Taj Mahal.
While the dimension and scale and sheer artistry of the famous marble-clad buildings have as much and maybe more to do with their astounding beauty as the material used in the building, there is no way, or reason, to deny that marble has it's own style, and can lend a touch of elegance to any structure and location where it is used. Certainly, a marble tile floor can heighten the sophistication of your décor, and make almost any room look luxurious.
Marble Tile Flooring
Marble tile flooring, like other tile floors, be they ceramic or vinyl or granite, is easy to purchase, install and maintain - it can be found in almost any shop that deals in flooring materials, and there are dealers who can provide you with bulk shipments, if you need to cover a larger space, like perhaps a piazza; it can be installed over your pre-existing floor provided the aforementioned is level and smooth; and cleaning requires nothing more than soap suds in warm water. So, if you've decided to install a new floor, or if you're building a new house, marble tile floors are something you should certainly consider, especially if you were leaning towards tiled floors already - marble is, by and large, less slippery than ceramic tiles, 
which is a huge point in its favour if you have children and/or accident-prone people in the family.
A lot of people get put off by the connotations of marble - pristine, stately, institutional - even when they rather like the idea of installing it. However, marble tile flooring is available in several colours, and can be purchased in shades that match the rest of your décor - install a rose marble tile floor in a room with pink or red walls, for instance, and watch the sheen of marble add richness to your room; or use grey-streaked marble in a blue room to make it appear colder.
Marble tile floors are amazingly beautiful, and can be as elegant or fun as your heart desires and imagination decrees.
