Prefab vs. Slabs: What’s the Difference?

One of the most common questions we’re asked is, “what’s the difference between prefabricated and slab countertops?” While both our prefabricated and slab countertops are of the same quality, there are some important differences you should be aware of, as they can affect the options available to you, as well as the cost.

Prefabricated materials are slabs of natural or engineered quartz which have been dressed with countertop-ready edging (in various styles) and are ready for custom cutting. Our prefabricated counters are partially processed at our production facility and then shipped to our warehouses. Once you select your prefabricated material, we cut it to size for your kitchen countertops, islands, backsplashes, and bathrooms.

This differs from slabs (sometimes referred to as raw slabs) which are larger pieces that need to be cut to size and fabricated before they’re installed. Sometimes slabs can allow there to be fewer seams, depending on the layout of your kitchen. There’s also generally more color, pattern, and edging options available with slabs.

The quality, style, and selection of our prefabricated stone countertops are equivalent to slabs. Our sales representative can help you determine what would work best for your project, but prefabricated countertops are typically the way to go. The prices of our prefabricated countertops are generally 30-40% less, making them a popular choice for homeowners who want both high-quality countertops and reasonable pricing.
