Rough estimate only — edge profiles, cutouts, and seams add to real-world quotes.

How this countertop estimate is built

We multiply counter length by depth for base area, add 10% for waste and slab layout inefficiency, then multiply by a typical installed price per square foot that includes basic fabrication. Sink and cooktop cutouts, upgraded edge profiles, waterfall edges, and backsplashes aren't included — get an itemized quote from a fabricator for those.

Frequently asked questions

Quartz typically runs a bit more than mid-range granite since it's an engineered product with consistent quality, though premium exotic granite slabs can cost more than standard quartz.

No — sink, cooktop, and outlet cutouts are typically priced separately by fabricators, along with edge profile upgrades and seam placement.
