The cost of buying granite for kitchen countertops will vary wildly depending on the type and rarity of the stone you choose. Another important factor is whether you purchase a solid one piece slab or multiple pieces which can bring down the cost.

The downside to using multiple pieces for your kitchen countertop is it will result in an unsightly seam visible on the surface. Purchasing granite remnants is a way to cut costs and potentially get a more expensive piece of granite for less.

Cost per Square foot

You can purchase granite slab countertops for $50 to $60 per square foot, while granite tiles countertops cost $10 to $40 per square foot.

Due to its size, granite slabs are more cost effective for large surfaces. Granite tiles will work best for kitchens with unique counter shape and lay-out.

Cost per Square foot when Installed

Because of the labor-intensive process , granite installation also cost higher compared to other countertop materials. Aside from the material itself, additional costs to be considered in installing a granite countertop are as follows:

  • Materials (consumables excluding granite) – $400 to $ 600
  • Edging – $ 200 to $300
  • Seams – $ 200 to $ 300
  • Labor – $ 300 to $500

Installing granite countertops may be a bit expensive so make sure to prepare your budget ahead of time. The cost of granite per square foot when installed is around $ 80 to $150 per square foot. 

It will take about $2000 to $4000 (including the granite) to furnish your kitchen with a granite countertop. An estimate will vary based on the rarity of the type and service costs for your local area. Although a bit pricey, granite countertops serve as a great investment because they will last a lifetime.

When it comes to comparison pricing, granite is often less expensive than materials like Corian, glass surfaces, and marble, and more expensive than laminate, tile, and quartz.

Factors that Affect the Price of Granite

Several factors affect the price of granite. It is generally priced based on how many soft minerals are present in its composition, its color and how it is cut.

Color. Rare granite colors such as blue, purple and red are more expensive than other colors. Beige and green have more abundant supply in the market which makes them cheaper.

Slab size. Larger granite slabs cost more and are more difficult to work with in installation.

Thickness. Thicker granite is more expensive because it is more durable.

Origin. Granite usually comes from Brazil, Spain, India, Italy and China – the last two being the most common origin. China manufactures the cheapest because they have lower labor cost. Granite from Italy and Brazil are the most expensive ones.

Although two slabs of equal quality may be at par, the country of origin affects the price of the granite considerably. Shipping costs also add up to granite’s market price. For example, Italian granite are priced much lower in Italy because they would take up less expense to be transported from its origin.

Grading of granite. Granite may either be “low grade”, “mid grade” or “high grade”. Low grade or commercial grade granite have more soft minerals mixed in them, thus making them more susceptible to damage. They have less color variation.

Mid-grade granite has pure colors but does not offer much uniqueness.  High grade granite is for those with rare colors and exotic patterns.

Granite Countertop Finishes

Granite countertops have three types of finishes: polished finish, honed finish and flamed finish.

Polished Finish

A polished finish is granite which has a glossy shine. It’s mirror like appearance reflects light well making it advisable to be used for areas which one may want to draw attention to. This makes it the most popular choice of granite finish for a kitchen countertop.

The flecks of stone and veining present in granite stands out in well lighted areas making spaces appear more elegant and dramatic.

Polished granite works well with modern, contemporary kitchens. It is also easier to maintain than the honed finish and the flamed finish. It can also be used as a flooring material for light traffic areas.

Honed Finish

Another type is the honed finish which has a buffed or matte appearance. Unlike the polished finish, this has no reflective surface and has a satiny texture.

Although lacking luster, it has a smooth texture, making it easy to clean. When used as a kitchen countertop, it adds a soft look, creating great contrast to high gloss cabinetry. A honed surface is advisable for those looking for an aged feel.

A honed surface does require more maintenance and can be more challenging to keep clean. However, It has the added benefit of not showing scratches as readily when compared to a polished surface. Scratches can be mostly avoided completely by always using a cutting board, not using abrasive materials, and taking care when dealing with heavy objects nearby.

Flamed Finish

The last type is the flamed finish which is characterized by its rough texture. This is achieved by heating the stone at a very high temperature, making the stone’s appearance more natural and its color more faded. The sheen levels vary depending on the hardness of the minerals in the stone.

Flamed finish granite are more typical in muted colors such as gray or shades of brown. It is most commonly used for exterior areas and for surfaces that are prone to moisture and works well with rustic themed houses.

Granite Edge Types

Kitchen with brazillian green granite

After selecting the color of your granite counter, another factor that you have to decide on is your countertop’s edge profile. Simply put, the granite edge profile is the shape the edge takes.

It is available in many shapes depending on cost and function. It may be in the form of rounded, semi-circle, square, to name a few. Custom edges are also available in selected fabricators and suppliers, don’t forget to ask them if you have a distinctive design in mind.

Aside from the aesthetic value it adds to your kitchen, the purpose of a smoothed rounded edge is to prevent granite from chipping off easily, thus adding to the years your countertop will last.

Although natural stone is characterized by its durability, unpolished edges lead to long term problems because the stone can crack from an impact at inside corners. In terms of maintenance, they are also easier to maintain

Countertops need a rounded over edge to maximize the thickness of the material. The typical thickness for a rounded profile is ¼ inch thick. The required thickness for granite countertops is at 1-1/2” inches for a rounded profile edge of 1/8 inch.

Granite edge profiles There are three general classifications for countertop edge profiles: the straight edge, the curved edge and the fancy edge.

Straight edge is the simplest of all profiles wherein the tip of your countertop material follows a simple straight cut.

Curved profiles on the other hand are rounded and may either be basic or fancy. This is an excellent choice for households with children since they lessen the need to worry about getting heads bumped on corners of your countertop. It softens the feel of the room and suits both classic and contemporary kitchen design styles.

Fancy edge is the most intricate and unique of all. It requires skilled workers and years of expertise in handling granite for precise cutting.

Generally more expensive than the straight edge and the curved edge, they are more of an investment for the value and character added to your home.  

These edges tend to be overwhelming if overused. It is best paired with simple cabinetry, creating a perfect design detail for your kitchen. This is a wise choice if you want to create a statement with your countertop.

Below is a list of common edge profiles for your granite countertop:

Eased Edge. Also known as the flat edge or straight edge, this is characterized by a basic square profile showing the full thickness of the stone. It is also the most cost efficient of all making it the most popular choice for people who remodel and design their kitchens.

It is clean, streamlined and matches any design style and concept. The corners are also slightly rounded, softened at a 3-centimeter space, to avoid damage to the material.

Pencil Edge.The pencil edge profile as its name suggests, is cut to shape like a pencil. It has a slightly angular edge that rounds into the vertical surface of the stone. It has a softer design than the eased or flat edge because of the rounded square design. It works best with contemporary style spaces.

Bullnose Edge. Completely rounded with both edges curved, the bullnose edge softens the feel of any space. It is half-circle in shape which makes it an appropriate choice for households which are concerned with safe.

However, they are less recommended for areas which easily get wet because spilled liquid tends to fall down the cabinets. Ideal application for this edge profile if for island countertops in the kitchen. Its design is also flexible since it suits both the classic and modern kitchen styles.

Hall Bullnose.As the name suggests, it has a round smooth profile with a flat bottom edge. The rounded off edge adds curve and also suits both the classic and modern style.

Chiseled Edge.The chiseled edge is the most natural looking of all edge profiles. Characterized by a lightly smoothed finish, it looks like a naturally broken piece of stone. The rough edge makes it fit for rustic style kitchens.

Granite Waterfall.The granite waterfall is one of the current design trends in kitchens today. The whole sides of the counter continuously fall of the edge, top to side, following the height of the counter.

It is dubbed the “waterfall” because it perfectly ends and flows to the floor creating a whole uniform surface. Paired with streamlined modern cabinets, it offers a clean and sleek statement.

Dupont Edge. Considered a premium edge shape that is a variation from the curved Ogee edge design. Rather than a curved edge the Dupont edge starts off with a short 90 degree angle that then flows down into a curved angle.

Ogee Edge.The ogee edge is an edge profile wherein the design has 2 sweeping arches: a concave arch that flows into a convex arch. When viewed from the side, it forms an “S” shape. Because of its dramatic outline, it is considered a premium cut and is more expensive.

Bevel Edge. The bevel profile is an edge that has a 45-degree angle, which may be on top or bottom of the countertop edge. The deeper the angle is cut, the wider the surface of the material looks.

It is a classic edge treatment that is not only aesthetically pleasing, but provides elegance, and is functional as well because it is easier to clean. It requires the countertop material to be at least 1 to 1 ½ inches thick. It has a classic luxurious look and works best with classic themed or country themed kitchens.

Other types of edge profiles which aren’t discussed above are variations of the basic types. Here are some of the examples:

  • Straight Edge: Straight with apron edge, Radius edge
  • Curved Edge: Tuscan curve, Ogee bullnose, Ogee over full bullnose
  • Fancy Edge: Versailles edge, Chiseled edge, Roman Ovollo, Ogee over Versailles, Ogee top and bottom, Demi bullnose, Demi bullnose with step-out

Aside from the wide range of edge profiles available in the market, you may also consult your granite supplier for fabricators for custom cut edges for a more unique look for your house.

Granite Slabs vs Tiles

Kitchen with granite tile countertop Granite Tile and Granite Slabs

There are 2 available types of granite countertops that are available in the market: the tile and the slab. In choosing the type of granite that is best suited for your project, you need to consider several factors.

One of which is the area or amount of space that needs to be covered and the other one is installation. Each of the factors will be discussed further in this detailed guide.

Granite Slabs

Granite slabs are ideal for projects which require a large amount of countertop space. Typically, a standard granite slab is 4 to 5 feet (W: 1.2 meters to 1.5 meters) wide, 7 to 9 feet (L: 2.1 to 2.7 meters) long, with a thickness of 1 ¼ inch (2 to 3 centimeters).

Due to its weight, it is not advisable to be used in a DIY / Do-It-Yourself project as it requires an extra work force to lift and set in place. It is advisable to leave the proper handling of granite slabs to professionals. You my either hire a contractor or directly deal with your supplier for the installation.

Granite slabs have incomparable beauty. Because of its size, it produces a whole uniform look without any visible seams and connections. It also eliminates the need to use grout, which makes it less prone to dirt and dust being inserted in between. It works best for projects that require a more modern, contemporary look.

Although more expensive than granite tiles, granite slabs are better in the long run because it is also easier to maintain.

Granite Slab Buying Tips

Some practical tips to consider in buying granite are the following:

Examine the material before purchasing. Carefully look out for any hole, hairline cracks,chip marks, and uneven surfaces. The presence of such makes the material more prone to damage.

Purchase thick granite. This is one of the most practical solutions showing its reward over time. It is ideal to buy thicker granite because the less thicker ones are more fragile and would require more support. They generally cost more, but serve as a great investment because of its superior quality. Ideal thickness for granite is 1 inch.

Ask for samples. Ask your supplier for available samples of the granite colors and patterns you choose. This is very essential in color matching with your cabinet.

You can get a general idea on how your counter would look like if placed against your cabinetry and also lessen the need to go back and forth the supplier in trying to make your final decision on which one to purchase.

Choose seamless granite. Not only do they look more uniform but they are also easier to maintain.

Check the granite’s polish quality. You can do this by using a simple test. Use any metallic object to scratch the surface of the material, if it leaves behind a mark, it indicates a poorly polished granite.

Color match. Each slab of granite is entirely unique from one another, if you want to ensure a more uniform color, purchase slabs coming form the same batch.

Granite Tiles

Granite Tile is another type of granite that is available in the market. It comes in a more manageable size, making it easier to handle. The standard size of granite tiles is usually 12 inches x 12 inches.

Granite tiles are also more cost effective, at about 50 percent less expensive than granite slabs. Since they come in modular sizes, you save on the surface material and the fabrication and installation process. 

In terms of application, they will work best in counters with a complicated shape. Although more affordable, it takes a longer process of installation by laying the tiles in a particular way.

To combine the pieces of granite tiles, grout is required to cover the seams. The grout must be of the same exact color as the granite and needs to be reapplied regularly to ensure that no food particles or dirt get stuck in between. 

Another downside of the seams in granite tiles is that they make granite tiles less quality than a whole slab. Design-wise, it offers more style options.

Granite Thicknesses

A frequently asked question is how thick are granite countertops? Granite is available in a variety of thicknesses, typically ¾ inches (around 1.90 centimeters) to 1-1/4 inches (3.175 centimeters) thick. However, the most ideal thickness for a granite countertop is 1-1/4 inches or 3 centimeters.

As a general rule in the industry, the thicker the granite is, the more expensive it is. In choosing the right thickness of granite for your countertop, there are a number of factors that need to be considered.

First is the look or style you want to achieve. Thicker countertops serve as a great focal point for any kitchen and they best complement modern and contemporary design.

Aside from this, the color of the countertop you choose also affects your decision. Typically darker colors are usually more available in a thicker variety than the lighter ones.

Lastly, the budget you have also plays a vital role in choosing the thickness of your granite countertop. Thicker granite slabs are rarer making them expensive in the market. This is the reason why they are often used for small areas such as an kitchen island countertop.

Best Places to Buy Granite

Kitchen with blizzard granite

• The best place to buy granite is from a stone manufacturer rather than a local home improvement store. Exclusive suppliers offer a more diverse range of choices and have a vast supply ready to order. Some pros of buying from a granite supplier are as follows:

• Buying in bulk from contractors and fabricators can save you significant money because they can give it to you at a lower price.

• Granite countertop businesses offer hundreds of material colors, patterns and finishes to choose from. Home improvement stores usually have a limited supply of around 30 options.

Local fabricators and contractors also offer installation. You can ask them for a full contract including the material and labor cost.

Before making a purchase, make sure you are dealing with a reputable stone manufacturer who stands by their product. Ensure they offer a warranty on their stone covering potential damage or staining.

Ensure you find out how long the warranty is good for and its total amount of coverage. Often a quality stone installer will offer service and customer care for the extension of the warranty period.

A granite surface warranty can protect you if something goes wrong or provide maintenance such as fixing cracks or sealing surfaces and seams periodically.

It’s also a good idea to make sure the company fabricating and/or installing your granite does not outsource the work to substandard contractors. Make sure they are doing the work themselves so you receive a quality product.

How to Measure Granite

Kitchen with lapidus granite island and white cabinetry

Measuring your countertop for granite installation only takes little effort.  These are the tools you will need:

  • Pencil or pen
  • Tape measure
  • Paper
  • Calculator

The general rule to follow is to measure your counter space twice. Estimation must be done carefully, precisely and accurately. Here are some tips you can follow in measuring your counter space:

Draw a diagram of your countertop space. Remember to include the backsplash in your drawing and measurement,

  • Include the sink, cooktop or any appliance which will be set into the granite. You need their measurements for the cut-outs on the surface.
  • Use a tape measure to measure the length of the counter space (wall to wall). Put the appropriate label of measurement on your drawing/diagram.
  • Measure the depth. The standard counter depth is 25.5 inches or around 60 centimeters.
  • Measure the backsplash length (this is the same as your counter’s length) and the backsplash height. The standard backsplash height is 4 inches or 10 centimeters.
  • Double check your measurements. Keep in mind that this must be done accurately, so always check if you measured correctly and labeled the diagram accordingly.
  • When all the measurements are complete, compute for the square footage. Follow this simple formula for measurements taken in inches:

(LENGTH of counter x DEPTH of counter) ÷ 144 inches = total square foot for countertop

(HEIGHT of backsplash x LENGTH of backsplash) ÷ 144 inches = total square foot for backsplash

Here’s a sample computation following the given formula. If your countertop’s length is 100 inches and the depth is 29 inches:

(L x D) ÷ 144 = total sq ft

100 in x 29 in = 2900 sq in

2900 sq in ÷ 144 sq in = 20.138 sq ft

Granite Counter Installation

Kitchen with absolute black granite counter on u shape island

Granite countertop installation is a labor-intensive process that requires precise measurements and skilled work. The type of material you use, whether it may be a granite tile or a granite slab will determine the steps you need to follow in installation.

Granite tiles may be a Do-It-Yourself process for someone with prior experience in laying tiles, while granite slabs are best left to professional contractors, as handling and installation is more tedious. You may hire a contractor or consult your granite supplier for labor cost and required assistance.

Some general tips to consider before installing granite:

  • Measurements should be taken accurately. As mentioned in the previous topic on “measuring your countertop”, the length, depth, and opening for appliances such as the range or hob cooktop and the sink must be precise.
  • Color matching is also very important. No granite slab is exactly alike, to ensure that your material has a close color, buy granite that belong to the same batch.
  • When in doubt, always hire a professional. Granite countertop installers are well skilled in their craft because of their experience and years spent practicing. You may always consult one if needed.

Installing granite slab countertop

Installing a Granite Slab Countertop

 Here is a step by step guide for projects which use granite slab countertops.

               Tools you’ll need:

  • Tape Measure
  • Light cardboard or kraft paper
  • Pencil
  • ¾” Plywood
  • Painter’s tape or masking tape
  • Level
  • Screws ( 1-¼” size)
  • Drill
  • Drill bit
  • Spade
  • Screwdriver
  • Jigsaw
  • Circular Saw
  • Putty knife
  • Seam setter
  • Silicone sealer
  • Polyester based resin
  • Epoxy
  • Caulking and Caulk gun
  • Granite Slab

Steps for Installing a Granite Slab Countertop:

Order the granite countertop material from your trusted supplier.

Create a full-size template of the actual measurement of the countertop. You may use paper or light cardboard for this. The reason for such is not all walls are perfectly leveled and a guide will ensure a perfect fit. Include all openings in your template.

Preparation of cabinets. Granite countertops require a plywood backing to support the weight of the slab. The typical thickness of the plywood substrate is ¾ inch. Cut plywood to fit on top of the base cabinet

Remember to cut in the exact same size without any allowance or overhang. Also, add a clearance in the thickness for the edging.

Attach the plywood backing onto the base cabinet by using screws. First drill a pilot hole to keep from splitting the face frame of the cabinet. Use 1 ¼” screws to secure it in place and make sure to center the screws.

Cut the hole for the sink in the plywood substrate. After securing the plywood backing in place, trace the exact outline of the sink onto the plywood then start cutting.

Use a jigsaw to cut around the sink hole but make it slightly bigger than the outline you drew; about 1/8 inch is enough. Drop sink in place. Run caulking around the sink rim.

Preparation of granite countertop. Dry fit the granite countertop on top the base cabinet to ensure an accurate fit. You may require an extra hand since granite slabs are extremely heavy.

To avoid breaking the stone, carry granite in a vertical position. If you need to remove a couple of millimeters for the granite to fit, scribe the material by using an circular saw with a dry-cut segmented blade. Adjustments must also be done with extra care.

Cut the hole for the sink in your granite countertop. Use the plywood sink hole as your guide. You may use an electric grinder with a diamond blade to cut through the granite’s surface.

Install the granite countertop. Set the granite in place on top of the plywood backing.

Join the granite seams. When you start fitting the granite slabs together, you can tape the edges to protect them. In joining the seams, use a color based epoxy.

Tighten the screws, and to keep the screws flushed, you may use a seam setter. The epoxy will dry out in an hour, and by then you can remove the seam setter.

A single edged razor maybe used to shave excess epoxy. Just remember to use even strokes as you hold the razor vertically.

Attach the granite countertop to the cabinets by using silicone. Apply silicone about the size of a penny with an ideal spacing of 6 to 12 inches apart.

Put caulking around the counter’s perimeter, where the stone meets the cabinet top.

Check the seams for any gaps. This may be filled by using a polyester based resin which matches the stone color.

Apply a granite sealer to protect your stone from oil, stain and spills from seeping into its surface. Ensure a full coverage and let dry for 24 hours

Installing a Granite Tile Countertop

Here is a step by step guide for projects which use granite tile countertops.

                Tools you’ll need:

  • Tape Measure
  • Light cardboard or kraft paper
  • Pencil
  • level
  • ¾” Plywood
  • Cement board backing
  • Screws
  • Drill
  • Drill bit
  • Spade
  • Screwdriver
  • Jigsaw
  • Trowel
  • Rubber padded grout float
  • Sponge
  • Carbide tip scoring tool
  • Mortar
  • Grout
  • Granite Tiles

Steps for Installing a Granite Tile Countertop:

Installing granite tile countertops involves the same preparation process used in installing granite slabs.

Create a full-size template of the actual measurement of the countertop. You may use paper or light cardboard for this. The reason for such is not all walls are perfectly leveled and a guide will ensure a perfect fit. Include all openings in your template.

Install the plywood substrate. Granite tile countertops also require a ¾ inch plywood backing for support. Cut plywood to fit on top of the base cabinet and add the desired overhang. If you want it to look thicker, you may double the plywood. Drill holes and secure the plywood on top of the base cabinets.

Install the cement backer board. Cover the plywood substrate with a cement backer board. Either cut it with a circular saw or score it with a scoring tool. Screw it on top of the plywood and attach 2” thick cement board strips to edges.

Cut the hole for the sink in the plywood substrate. Use a jigsaw to cut around the sink hole but make it slightly bigger than the outline you drew, about 1/8 inch is enough. Drop sink in place. Run caulking around the sink rim.

Lay the granite tiles. Spread thin-set tile adhesive on the cement backer board worktop. Lay tiles outer edges first. For the edging, remember to overhang the tiles.

Apply grout in between the seams of granite tiles. Use the rubber padded grout float to apply the grout to the seams then wipe off excess with a damp sponge. Allow to dry for 24 hours.

Apply sealer to the seams. This will serve as an extra protection against dirt and spills.
