Dekton vs. quartz vs. granite countertops: what’s the difference?

Choosing between a Dekton, quartz, or granite countertop can be challenging when renovating your kitchen. All three are excellent materials that could easily satisfy your needs.

ROCHON, your kitchen designer in Quebec, breaks down each option to help you choose the right countertop for your home.

Manufacturing processes

Each of these three materials is produced through a distinct manufacturing process.

Dekton is the intellectual property of the Spanish multinational Cosentino. It involves a metamorphic process that subjects natural stone to extreme temperatures and pressures.

Granite must be quarried, transported, and then cut into the shape of the countertop. Among the three processes, it is the most labour-intensive and least environmentally friendly.

Quartz is also extracted from the earth, but it is reduced to fine dust before being agglomerated with resin and subjected to intense heat and pressure.

The appearance of each material

Granite is a highly versatile stone. It naturally comes in many colours and patterns, allowing you to choose from a wide range of options while maintaining a natural aesthetic.

Because it is a natural stone rather than an engineered one, it is harder to control the look of each slab. The final result may differ from the sample shown by your designer. That is why we always recommend that clients go and select their slab directly from the supplier.

Thanks to the pigments added to quartz during production, it can be matched to virtually any colour. This makes it even more adaptable than granite.

The manufacturing process of Dekton allows it to take on any pattern or colour. It is even available in a finish that replicates the look of the other two materials. A Dekton countertop can complement any decor.

Durability: quartz, Dekton, or granite countertops

In terms of durability, all three materials are very long-lasting and, with proper care, will stand the test of time.

Each has varying levels of resistance to heat, moisture, and stains.

Heat resistance

Dekton and granite countertops are highly resistant to heat. Quartz can be damaged by intense heat. For example, it is strongly advised not to place a hot pan directly on a quartz countertop.

More specifically, Dekton withstands temperatures up to 538°C (1,000°F) without damage, so you can set a hot dish straight from the oven without a trivet. Quartz, on the other hand, can discolour or have its resin weakened above 150°C (300°F). Granite handles occasional heat well, but a sudden thermal shock could cause it to crack in rare cases.

Moisture resistance

Moisture itself is not a problem for any of these three materials.

However, the porous nature of granite can allow liquid to seep in and create permanent stains. It is therefore important not to leave coloured liquids on a granite countertop for extended periods, especially in the case of light-coloured natural stone.

Stain resistance

With the exception of liquids that can soak into granite, all three materials are very resistant to stains when cleaned properly.

UV resistance and outdoor use

An often-overlooked factor is UV resistance. Dekton is 100% UV stable, meaning it will not fade, degrade, or lose its appearance even after years of direct sun exposure. This makes it the top choice for outdoor kitchens, patios, and barbecue areas.

Quartz, by contrast, is not recommended for outdoor use. Prolonged UV exposure can cause its surface to yellow or discolour, as the resin it contains is sensitive to direct sunlight. Granite handles UV better than quartz, but some shades may still fade slightly over time.

Estimated lifespan

Longevity is an important factor when calculating the real cost of your countertop:

• Dekton: 25 years and more. Its ultra-compact composition makes it extremely resistant to daily wear.
• Quartz: 15 to 25 years. Very durable with minimal maintenance, although the resin can deteriorate over the long term.
• Granite: 20 to 30 years and more. With annual resealing and proper care, granite can last a lifetime.

When you factor in the price per year of use, Dekton often becomes a comparable investment to the other materials, despite its higher upfront cost.

Ease of maintenance

Granite generally needs to be washed regularly with a mild soap to maintain its lustre and beauty. In addition, for increased longevity, it should be resealed once a year.

Quartz and Dekton also need to be cleaned regularly with a mild soap, but have no other particular maintenance requirements.

Regardless of your countertop material, it is important to avoid abrasive cleaning products, as they can cause damage. For stubborn stains, we recommend consulting the manufacturer’s care guide.

Repairability

Quartz and granite can usually be repaired using clear adhesives or epoxy to fill cracks and reattach broken pieces. They are therefore materials that offer excellent longevity for those with a bit of DIY ability.

With Dekton, a crack in the surface can be covered, but the manufacturer notes that cracks will continue to grow. Dekton cannot be easily repaired. This is a drawback that it compensates for with its exceptionally high durability.

Cost: Dekton vs. granite vs. quartz countertops

The cost of a quartz or granite countertop can vary greatly depending on the manufacturer’s quality. However, both are generally available at similar price points, with granite typically being slightly less expensive.

If you are deciding between Dekton and quartz, it is important to know that Dekton is often slightly more expensive than quartz and granite.

Price per square foot in Quebec in 2026

To help you plan your budget, here are the average price ranges in Quebec in 2026 (material and installation included):

• Quartz: $50 to $150 per sq. ft. The price varies depending on the manufacturer, colour, and edge profile chosen. For a standard kitchen of 30 to 40 sq. ft., budget between $1,500 and $6,000.
• Granite: $50 to $150 per sq. ft. Similar to quartz, granite offers a comparable price range. Rare or exotic colours cost more.
• Dekton: $60 to $175 per sq. ft. Positioned at the higher end of the market, Dekton justifies its price through exceptional durability and versatility (both indoor and outdoor).

Don’t forget to include cutting, edge profiling, backsplash, and finishing costs in your budget. A ROCHON designer can provide a precise estimate based on the exact dimensions of your project.

Resale value: a smart investment

The kitchen is often the feature that sells a home. A quality countertop can have a significant impact on the perceived value of your property. In Quebec, a well-executed kitchen renovation can recoup between 75 and 100% of the investment at resale.

Quartz is currently the most sought-after material among buyers due to its minimal maintenance and modern appearance. Granite retains a high perceived value thanks to its natural character and uniqueness. Dekton, while less well known to the general public, is increasingly appreciated in upscale properties.

ROCHON Tip: don’t over-invest. Make sure the cost of your countertop is proportional to the overall value of your property and the market in your neighbourhood.

Environmental impact and sustainability

For homeowners mindful of their ecological footprint, here is what you need to know:

Granite is a non-renewable natural resource. Quarrying has a notable environmental impact (heavy transport, extraction energy), especially when imported from overseas. Choose local or North American granite to reduce your carbon footprint.

Quartz and Dekton are engineered materials. Their production consumes energy, but generates less waste than natural stone extraction. Cosentino, the manufacturer of Dekton, has implemented recycling programmes and closed-loop water systems at its plants.

For a greener choice, ask your ROCHON designer about countertop options made from recycled materials or certified by recognized environmental organizations.

Which is the best choice?

Granite, Dekton, or quartz? Each option has its advantages and disadvantages. All three are excellent choices for your kitchen countertop. Dekton is also an outstanding choice for outdoor kitchens.

Dekton may be the better choice if you want something extremely durable or are looking for a very specific style.

You might prefer quartz or granite if you are looking for less expensive options that also offer a number of respective advantages.

Ultimately, your countertop should be made from a material you love and that fits your budget. There is no single right answer.
