Granite and quartz dominate the countertop market for good reasons — but they serve different projects. This side-by-side breakdown covers durability, maintenance, cost, and aesthetics so you can decide with data, not guesswork.
The Core Difference: Natural Stone vs Engineered Surface
Granite is a 100 % natural igneous rock quarried in slabs. Each piece is unique, with mineral composition that varies by origin. Quartz countertops are engineered: roughly 90–94 % crushed quartz aggregate bound with polymer resins, pigments, and additives. That single distinction drives almost every performance difference between the two.
Neither material is inherently superior. The right choice depends on how your kitchen or bathroom is used, how much maintenance you’re willing to commit to, and the aesthetic you’re after. The table below gives you the full picture at a glance.
| Criterion | Granite | Quartz |
|---|---|---|
| Composition | 100 % natural igneous rock | ~93 % quartz + resin binder |
| Hardness (Mohs) | 6–7 | 7–7.5 |
| Porosity | Moderate — requires sealing | Non-porous — no sealing needed |
| Heat resistance | Excellent (direct pans OK) | Limited — resin can discolour above 150 °C |
| Scratch resistance | High | Very high |
| Pattern consistency | Unique / unrepeatable | Uniform / repeatable |
| Maintenance | Seal every 1–3 years | Wipe clean, no sealing |
| Typical installed cost | £40–£100 /m² | £50–£120 /m² |
| Resale value perception | Premium — natural stone | Premium — modern/clean look |
Durability: Where Each Material Wins
Granite’s igneous origin makes it one of the hardest natural stones available for kitchen use. It resists scratches from knives and handles thermal shock well — you can set a hot pan directly on it without risk of cracking or discolouration. Its weak point is porosity: unsealed granite absorbs liquids, and oils or acidic spills can stain permanently if left unattended.
Quartz scores marginally higher on scratch hardness (Mohs 7–7.5 vs granite’s 6–7) and, because it is non-porous, bacteria and moisture cannot penetrate the surface. However, the resin binder introduces a thermal ceiling. Prolonged contact with cookware above roughly 150 °C can cause resin discolouration or micro-cracking — a failure mode granite simply does not have.
Maintenance Requirements in Practice
Granite requires periodic sealing — typically once every 1 to 3 years depending on the stone’s porosity and your usage intensity. A simple water-bead test tells you when it’s time: pour a few drops on the surface; if the stone darkens and absorbs the water within 4 minutes, reseal. The process takes under an hour and uses standard impregnating sealers available from any stone supplier.
Quartz needs no sealing. Daily cleaning with mild soap and a soft cloth is sufficient. Harsh abrasives and bleach-based products should be avoided because they degrade the resin over time. For professional kitchens with high chemical-cleaning schedules, verify compatibility with the specific quartz brand before specifying.
Aesthetics: Unique vs Consistent
Granite’s visual appeal comes from its geological randomness. No two slabs are identical — mineral deposits of feldspar, mica, and quartz create patterns that cannot be replicated. This uniqueness is a selling point in luxury residential projects and hospitality interiors where individuality matters. The flip side: matching extra pieces or replacing a damaged section later can be difficult.
Quartz offers pattern repeatability. Manufacturers can produce large runs of a consistent colour and veining style, which simplifies specification for commercial projects, multi-unit residential developments, and kitchen island extensions where you need slabs to match precisely. Some premium quartz lines now mimic Carrara or Calacatta marble veining convincingly, broadening the design palette.
Granite gives you a piece of the planet’s history. Quartz gives you engineering precision. The best kitchens we see pair the two ideas — not compete between them.
Cost Comparison: What Drives the Price Gap
Both materials sit in a similar price bracket at the installed level, but the drivers differ. Granite pricing reflects quarry location, slab thickness, finish (polished vs honed vs brushed), and colour rarity. Entry-level granite runs from approximately £40/m² for common black or grey varieties; premium exotics with rare mineral patterns can exceed £200/m².
Quartz pricing is driven by brand, pigment complexity, and slab format. Basic white/grey engineered quartz starts around £50/m²; designer-finish large-format slabs from leading European manufacturers reach £120–£150/m². Fabrication and edge profiling costs are broadly comparable for both materials.
Which Material Is Right for Your Project?
- High-traffic family kitchen: Quartz wins here. Non-porous surface handles juice, wine, and sauce spills without staining, and there is no annual sealing task to remember.
- Luxury residential or hospitality: Granite delivers the natural stone narrative and visual exclusivity that premium projects demand. Pair it with a quality impregnating sealer and a maintenance plan.
- Outdoor or BBQ counters: Granite is the only viable choice between the two. UV exposure and temperature cycling degrade quartz resin over time; granite is inert to both.
- Commercial kitchen or food-prep facility: Verify NSF certification for the specific quartz product. Non-porous quartz can meet hygiene codes where granite would require certified sealing protocols.
- Budget-sensitive renovation: Compare installed quotes for both. In markets where local granite is quarried, it can undercut quartz on slab cost; where quartz is manufactured domestically, the reverse is true.
Where Marble Fits: A Third Option Worth Considering
Neither granite nor quartz covers every design brief. When the requirement is warmth, elegance, or a natural material with a distinctive character that neither engineered surfaces nor igneous stone provide, marble becomes the specification of choice — particularly for bathroom vanities, feature walls, and statement kitchen islands where durability demands are lower and visual impact is paramount.
Pulycort’s marble range includes Spanish-origin varieties such as Crema Marfil, Blanco Ibiza, Negro Marquina, and Tundra Grey — each with defined porosity characteristics, available finishes, and technical datasheets for professional specification.

There is no universal winner between quartz and granite — the right material depends on how the surface will actually be used. Quartz is the more practical choice for busy residential kitchens: non-porous, low-maintenance, and consistently patterned. Granite is the stronger specification for luxury and outdoor applications where heat resistance and natural stone authenticity matter more than maintenance convenience. If your brief calls for warmth, veining depth, or a material with genuine geological character — and the application allows for proper sealing — natural stone remains unmatched. For bathroom vanities, feature walls, and statement surfaces where marble is appropriate, consider Pulycort’s Spanish-origin marble range as a third path that neither engineered quartz nor igneous granite can replicate.
