Quick Comparison at a Glance
| Feature | Granite | Marble |
|---|---|---|
| Stone Type | Igneous (formed from cooling magma) | Metamorphic (formed from limestone under heat/pressure) |
| Mohs Hardness | 6-7 (very hard) | 3-5 (softer) |
| Heat Resistance | Excellent — hot pans directly on surface | Good — use trivets to be safe |
| Scratch Resistance | Excellent — resists knife scratches | Poor — scratches from everyday use |
| Stain Resistance | Good when sealed annually | Poor — etches from acids (citrus, wine, vinegar) |
| Sealing Required | Once per year | Every 6-12 months |
| Cost (Installed/sq ft) | $45-$120 | $60-$230 |
| Lifespan | 50+ years | 20-30 years (high-maintenance); longer with patina acceptance |
| Best Applications | Kitchen countertops, high-traffic floors, outdoor paving | Bathroom vanities, fireplace surrounds, low-traffic floors, wall cladding |
| Outdoor Use | Excellent — UV stable, freeze-thaw resistant | Not recommended — weathers and stains |
When to Choose Granite
Choose granite if you cook frequently, need a countertop that handles hot pans and knife work without complaint, want the best balance of durability and price, or need stone for outdoor applications. Granite is the practical choice — it works hard and asks for little in return beyond annual sealing. For busy family kitchens, granite has been the go-to material for decades for good reason.
When to Choose Marble
Choose marble if aesthetics are the top priority and you are installing in a low-wear area. A marble bathroom vanity or fireplace surround brings timeless elegance that granite cannot match. Marble requires a philosophical commitment: either you maintain it carefully (immediate spill cleanup, coasters, frequent sealing), or you accept the patina of use that develops over time. Many designers and homeowners consider this lived-in character part of marble's appeal. Marble is also the traditional choice for pastry and baking stations — its naturally cool surface is ideal for working with dough.
Cost Comparison
Granite costs $45-$120/sq ft installed, with common colours like Tan Brown and Ubatuba at the lower end and exotic blues at the premium end. Marble costs $60-$230+/sq ft installed, with Carrara at the entry level and Calacatta or Statuario at the luxury end. Material cost is 50-70% of the total — fabrication, templating, and installation make up the remainder. For a typical 40 sq ft kitchen: granite $2,500-$5,000, marble $3,500-$8,000+.
Maintenance Comparison
Granite needs annual sealing (a 20-minute DIY task) and daily wiping with pH-neutral cleaner. Marble needs sealing every 6-12 months, immediate cleanup of any acidic spill, and professional polishing every 3-5 years in high-traffic areas. Over a 10-year period, marble maintenance costs are roughly 3-5× higher than granite. If you want the marble look without the maintenance, consider quartzite — it offers marble-like veining with granite-level durability at $60-$150/sq ft.
