A direct comparison of the four most requested countertop surfaces for Florida homes, from Altar Stone Countertops in Sarasota.
| Attribute | Quartz | Granite | Marble | Quartzite |
|---|---|---|---|---|
| Durability (scratch & chip) | Very high — engineered, consistent hardness | High — very hard natural stone | Moderate — softer, scratches and etches | Highest — hardest of the four natural stones |
| Heat resistance | Moderate — use trivets, resin can scorch | Excellent — hot pans directly on surface | Very good — naturally heat tolerant | Excellent — handles high heat well |
| Maintenance | Lowest — non-porous, no sealing ever | Low — seal roughly once a year | Highest — seal often, wipe acids immediately | Low to moderate — periodic sealing |
| Typical cost per sq ft installed | $70 – $120 | $60 – $100 | $80 – $150 | $85 – $150 |
| Best use case | Busy family kitchens, bathrooms, laundry | Kitchens with heavy cooking, islands, bars | Statement islands, vanities, baking areas | Outdoor kitchens, lanais, sunlit kitchens |
| Florida humidity suitability | Excellent — non-porous, no moisture absorption | Very good — sealed surface resists moisture | Good — requires diligent sealing | Excellent — dense, low absorption |
| Florida UV / sun suitability | Indoor only — resin can discolor in direct sun | Very good — UV stable outdoors | Good — UV stable but stains outdoors | Excellent — UV stable, ideal outdoors |
Installed cost ranges reflect typical Southwest Florida projects and vary with slab selection, square footage, edge profile and cutouts.
Quartz is the best all-around choice for an indoor Florida kitchen because it is non-porous, never needs sealing, and is unaffected by coastal humidity. For outdoor kitchens or surfaces in direct sunlight, quartzite is the better choice because it is UV-stable and will not discolor.
No. Engineered quartz contains resin binders that can fade, yellow or warp under prolonged Florida UV exposure. For lanais and outdoor kitchens we recommend quartzite or granite, which are natural stones that remain UV-stable.
No. Quartzite is a natural stone quarried in slabs and is the hardest of these four materials. Quartz is an engineered surface made of crushed natural quartz bound with resin and pigment, which is why it offers consistent color but less heat and UV tolerance.
Installed costs in Southwest Florida generally run $60 to $100 per square foot for granite, $70 to $120 for quartz, $80 to $150 for marble and $85 to $150 for quartzite. The exact figure depends on slab selection, square footage, edge profile and cutouts.
Quartz requires the least maintenance because it is non-porous and never needs to be sealed. Granite and quartzite need periodic sealing, and marble requires the most attention because it etches when exposed to acidic liquids.
Granite and quartzite handle direct heat best, since both are natural stones formed under heat and pressure. Quartz should be protected with trivets because its resin binder can scorch.
