Can I Cut a Man-Made Marble Vanity?

Circular Saw

• One of the quickest and easiest ways to cut a piece of cultured marble for a vanity is with a circular saw that is fitted with a type of stone blade, either carbide or diamond tipped. After the blade’s depth is set according to the thickness of the piece of cultured marble, you rip the piece down to size just as you would a piece of wood. This method is best reserved for cutting cultured marble pieces prior to their installation.

Stone-Cutting Saw

• Hand-held stone-cutting saws also are used to cut cultured marble. They resemble circular saws in most fashions, except that they have a special guide along the edge of the blade that can be set to the depth of the stone. Many stone-cutting saws include a water-feed option so that you can use water to dampen their blade and keep it cool when cutting. That technique is necessary only when cutting thick pieces of stone. Man-made marble pieces are rarely more than 1/2 to 3/4 inch thick.

Tile Wet Saw

• A tile wet saw is the best option for cutting a piece of man-made marble prior to its installation. The saw's blades are specially designed to cut through tiles and stones, and they work well with cultured marble. Because many cultured marble installations incorporate aspects of tile, such as a bathroom with a cultured marble vanity and a tile shower, usually a tile wet saw is already in place and set up when you install the vanity.

Angle Grinder

• If you are dealing with a cultured marble vanity that is already in place, then the only option for some of the cuts is an angle grinder retro-fitted with a stone-cutting blade. That is because stone-cutting saws and circular saws are too large to fit into the spaces along the vanity back-splash or in the corners. The blade of an angle grinder, on the other hand, can sink into the corners and cut through them with ease. The cutting process is exceptionally dusty, however; place plastic over doors to the room and open all exterior windows before cutting.
