Quartz vs Granite Countertops: Which Is Better for Your Kitchen?

When it comes to kitchen and bathroom countertops, two materials dominate the conversation: quartz and granite. Both are premium choices, but they differ in significant ways. Understanding those differences will help you make a decision you’ll be happy with for decades.

What Is Quartz?

Engineered quartz countertops are manufactured from 90–95% crushed natural quartz crystal, bound together with polymer resins and pigments. The result is an incredibly consistent, non-porous surface that requires virtually no maintenance. Quartz countertops don’t need sealing, resist staining, and come in a wide range of colours and patterns. According to the Quartz entry on Wikipedia, quartz is the second most abundant mineral in Earth’s continental crust, which is why engineered quartz surfaces are so consistent in hardness.

What Is Granite?

Granite is a natural igneous stone quarried from the earth. Each slab is unique, with its own veining, mineral patterns, and colour variations. Granite is extremely hard and heat-resistant when properly sealed. Learn more about its geological composition at Wikipedia’s granite article. However, granite is porous and must be sealed regularly to prevent staining and bacteria from penetrating the surface.

Quartz vs Granite: Durability

Both materials are extremely durable, but in different ways. Quartz scores 7 on the Mohs hardness scale and is resistant to chips and cracks under normal use. Granite ranges from 6–7 on the Mohs scale of mineral hardness and can be more susceptible to chipping at the edges. Quartz wins on stain resistance due to its non-porous surface; granite requires annual sealing to maintain the same protection.

Quartz vs Granite: Maintenance

Quartz requires minimal upkeep — just wipe with a damp cloth and mild soap. No sealing, no special cleaners. Granite, by contrast, needs to be sealed every 1–3 years depending on use, and acidic substances like lemon juice or wine can etch the surface if left sitting. HGTV’s countertop maintenance guide confirms that regular sealing is one of the top upkeep tasks granite owners overlook.

Quartz vs Granite: Cost

In Canada, both materials fall in a similar price range — typically $60–$150+ per square foot installed. For a full breakdown of what affects quartz pricing, see our quartz countertop cost guide. Entry-level granite can be slightly less expensive than premium quartz, but high-end granite and quartz are comparably priced. Factor in long-term sealing costs for granite when budgeting.

What About Porcelain?

If you’re open to alternatives, it’s worth considering porcelain slabs for countertops. Porcelain is fully UV-stable, scratch-resistant, and requires zero sealing — making it an excellent option for outdoor kitchens or sunlit spaces where quartz can discolour over time.

Which Should You Choose?

Choose quartz if you want a low-maintenance, consistent surface with a wide variety of colour options. It’s ideal for busy kitchens and families. Choose granite if you want a truly unique, natural look and don’t mind the annual sealing routine. At Rubyx Stone Collection, our team can walk you through both options, provide samples, and help you find the right surface for your space and budget. Contact us to get started.

Frequently Asked Questions

Is quartz or granite more durable?

Both are highly durable, but quartz is generally considered the more practical choice for everyday use. Quartz is non-porous, so it resists staining without any sealing, and its engineered composition makes it highly consistent in hardness. Granite is slightly softer on average and must be sealed annually to prevent staining. For high-traffic kitchens, quartz tends to hold up better with less maintenance.

Does quartz or granite add more value to a home?

Both quartz and granite are considered premium countertop materials and add real estate value compared to laminate or tile. Quartz has become increasingly popular with buyers due to its consistency and low maintenance, while premium granite slabs retain strong appeal for their uniqueness. Either material is a sound investment; the best choice depends on your kitchen’s overall style and the preferences of buyers in your market.

Can you use quartz outdoors?

Standard engineered quartz is not recommended for outdoor use. The polymer resins that bind quartz crystals together can discolour and degrade when exposed to prolonged UV light, which is why most manufacturers void their warranties for outdoor installations. Granite handles outdoor environments better than quartz. For outdoor kitchens or sun-exposed terraces, porcelain slabs are the most UV-stable option available.

How do I know if my countertop is quartz or granite?

The easiest way is to look closely at the pattern. Granite has natural, random variations — no two areas look exactly the same, and you’ll often see visible mineral crystals (feldspar, mica, quartz). Engineered quartz has a more uniform, consistent appearance across the slab. You can also check the underside or a chip edge: granite will show a coarse-grained crystalline texture, while quartz will appear more homogeneous. If unsure, a stone supplier or fabricator can identify it quickly.
