Price, timeline, and prefab vs slab — answered straight, before anyone comes to your house.
Sourced 2026 averages for Orange, CA put installed quartz countertops at roughly $61 per square foot for basic, $67 for better and $73 for best, inside a national installed range of about $50–$150 per square foot for stone generally. Most Orange County kitchens carry 40 to 55 square feet, so a standard quartz replacement lands broadly in the $2,400–$4,000 range.
Cheaper route: prefab quartz, sold pre-cut by the piece. Full 2026 price breakdown →
Usually 7 to 14 days from approved quote to finished countertops. You pick your stone — ideally by walking a slab yard rather than choosing from a sample chip. A technician takes a free in-home template, 45 minutes to 2 hours, where your edge profile, overhangs and every seam location get locked in. Fabrication runs 3 to 7 business days. Install day takes 4 to 8 hours and starts with removal of old countertops and haul-away.
The pacing item is almost always whether your material is sitting in a local warehouse, not the installer's schedule. Day-by-day timeline →
Prefab is the Southern California term for quartz or granite pre-cut to a standard countertop size, roughly 26″ deep by 96″ or 108″ long, with the front edge profile already polished at the factory. It costs materially less and suits standard galley, L-shape and U-shape kitchens. A full slab wins when you have a large island, a waterfall end, unusual angles, or you want to control exactly where the seam falls.
Plenty of homeowners split it: prefab on the perimeter runs, a full slab on the island. Prefab vs slab, compared properly →
Quartz is the volume leader in Orange County — non-porous, never needs sealing, and consistent slab to slab. Brands stocked locally include Cambria, MSI, Caesarstone, Silestone, Viatera and HanStone; MSI has particularly deep Southern California distribution, so it is often quickest to get. Granite is natural, heat-proof and unique slab to slab. Quartzite gives you a marble look with more durability. Porcelain handles UV and heat well, which makes it strong for outdoor kitchens.
