Silestone Countertops Cost Guide

The average cost of Silestone countertops runs anywhere from a low of $50 to a high of up to $100 per square foot, depending on thickness and grade of quality. Average thickness varies but is usually around .75 to an inch thick. Adding inches to anything above this can add on a price of $4 or more per square foot. This does not include the total price of installation. Total prices for installation and materials combined range from $350 for a low end type of Silestone to $475 for best quality Silestone installation per square foot. Other costs include extra charges for a backsplash or added seams. The price can also fluctuate, according to the company being used and the type of Silestone. The best time to search for prices on Silestone are in the fall and winter. This is when most businesses usually have down time and offer better deals.

The Costs

  • Average minimum cost of Silestone countertops: $55 per square foot

  • Average maximum cost of Silestone countertops: $85 per square foot

Costs also vary based on the type of pattern being used. Different colors and patterns range from a low end of $55 to a high of $95 per square foot. The square footage of the countertop should be measured first when taking costs into consideration since a large countertop can be much more expensive to install. Edge details will also run an extra $15 to $30 per square foot, depending on the design. Installing Silestone countertop can be a difficult task and is best left to a professional contractor due to the heavy nature of the quartz. Also, most contracting companies can get better deals on the price of Silestone or may have contractual rates with suppliers that are often lower than consumer rates.


Silestone is a man-made engineered stone made from a mix of an average of 93 percent crushed quartz and 7 percent polyester resin, which is added as a binding agent. The mixture of mostly quartz along with resins and polymers provides for a very hard surface akin to granite. Quartz is a crystallized silicon dioxide that is usually naturally found either transparent or white. Coming into contact with impurities during its formation causes it to take on many other colors. It is also acid resistant. The appearance varies based on how the quartz is ground. A fine grind produces a smoother look while a coarse grind makes for a rougher appearance flecked with pieces of stone.

The different brands of Silestone include Cambria, Caesarstone, Dupont Zodiaq and Okite. Other manufacturers include Avanza and Breton. Silestone quartz does not have a heavy environmental impact. It is the second most abundant material found in the earth’s crust; therefore, it is plentiful. However, the acrylic resin most often used in the countertop can contain fillers made from bauxite ore, which usually originates from mining procedures in developing countries that use toxic conditions. Some brands, such as Cambria, are mined exclusively in the United States and therefore not subject to the volatile types of mining conditions nor environmental impact.

Advantages of Using Silestone

Silestone is a quartz surface that is extremely durable and one of the hardest minerals in the world next to diamonds and sapphires. This protects it against the type of wear and chipping that can happen in softer materials. Its hardness makes it great for countertops where plates, glasses, silverware and other things can drop and damage a surface. Silestone is dense and non-porous, making it resistant to spills and stains from liquids such as coffee, wine, olive oil and lemon juice.

Additional Pros:

  • Silestone does not need sealing or polishing and is low maintenance. The quartz in Silestone gives off a glossy sheen that does not need constant cleaning or polishing.

  • Crack resistant.

  • Material stays cool to the touch and is great for defrosting foods and other frozen items.

  • Long lasting.

  • Comes in a variety of different colors and design options.

  • Easy to clean and care for with mild soap and water.

Silestone is also scratch-resistant and bacteria-resistant. This provides for antimicrobial protection, which is great for countertops. Countertops can often become home to a host of bacteria from constant physical contact and food contact. The bacteriostatic formula in Silestone uses silver ions to prevent bacteria from living in the cracks and seals of the countertop.

Disadvantages of Using Silestone

One of the main disadvantages of using Silestone is its high price. The cost of Silestone is higher than other similar countertop brands and materials. In fact, it is one of the most expensive types of countertop material on the market today. This is due to the amount of stone material needed to manufacture it. If cost is an issue, deciding on whether or not to use Silestone boils down to the need for maintenance or care. Other laminates will be much less expensive than Silestone but will also require more care. Another option often considered in place of Silestone as a sometimes cheaper alternative is granite.

Other Cons of Silestone

  • Seams are more visible than other type of counters, especially in large countertops.

  • Silestone is not very tolerant to high levels of heat.

  • Silestone can sometimes have a “processed” look that can be generic compared to other countertops.

  • Although Silestone does come in a variety of colors, it is limited in its variety compared to other materials such as laminate or granite countertops.

  • Less room for customization due to the generic nature of color schemes available.

In all, Silestone is a highly durable and beautiful material that will last for many years to come. If cost effectiveness is not an issue, Silestone is a wonderful option for those in the market for a new countertop. It is especially useful and ideal for homes where the kitchen will be a main focal point and where most activity is done in the kitchen. Putting the Silestone countertop to good use is the best way to get the most out of one’s money with this standout countertop material.
