Materials
Best Commercial Countertop Materials
Quartz
Non-porous, no sealing, and consistent from slab to slab. Carries a manufacturer warranty. Most brands are NSF certified for food contact.
Porcelain
Thin and light, so it goes where the weight matters. Restaurant kitchen walls, restroom walls, elevator surrounds.
Ultracompact
Dekton and similar. Heat, UV, scratching, staining. We fabricate it in house.
Quartzite
Around 7 on the Mohs scale, harder than granite, and it holds up outdoors.
Marble
Reception desks, lobbies, boardrooms. When the surface is the first thing anyone sees.
Not sure yet? That's normal. Come in and we'll narrow it down together.

Timing
Lock In Your Material Early
Countertops go in near the end, but the material decision can't wait that long. Slabs sell, quarries run dry, and supply chains surprise everybody.
Just went through the plans?

Pricing
How Much Do Commercial Countertops Cost?
Pricing matters. It's the first question everybody asks, and we get it.
Pricing matters. It's the first question everybody asks, and we get it. But there's no price list in this business. Two suppliers can charge different prices for the same slab, and the work you want done changes the rest of it.
About 95% of countertops fall between $55 and $150 per square foot installed. A few materials always run above that: Blue Bahia granite, Blue Macaubas and Cristallo quartzites, the Calacatta and Statuario Italian marble families, and onyx. If one of those is on the spec, quote it early so there's no sticker shock.
- Sourcing. Whatever's on the spec, we find it and make it happen. If it's already on our floor, you're priced per square foot for the footage you use. If we bring it in, slabs are sold whole. That's how the industry works.
- Project Size. Bigger jobs cost more, but they usually get better per-square-foot pricing.
- Complexity. Waterfall ends, mitered edges, integrated sinks. The detail moves the number more than the square footage does.
- Waste. Intricate shapes and matching pattern piece to piece mean more material goes unused. We lay out every cut digitally to get the most out of each slab, but the pattern decides. Beautiful, and it comes at a cost.
Desirability drives price too. What's trendy costs more, what's out of fashion costs less. Natural stone is also quarried, so it isn't always there when your schedule says it should be.
Comparing Quotes?
The service side, templating, fabrication, edges, and installation, runs about $30 to $50 per square foot and is fairly consistent across the industry. The big difference between quotes is material.
Watch for quotes that don't spell out scope, because any change becomes an extra. A cheaper number usually means a different material or brand, not a better deal.
Our quotes spell it out line by line: templating, fabrication, edges, cutouts, installation, plus whatever else the job takes. You see exactly what you're paying for.
