## Where the slab is born matters

**Precast**

 are built in the shop, cured under controlled conditions for weeks, then transported to the home for install. The shop process gives the best finish control: consistent thickness, smooth surface, refined edges.

**Cast-in-place** countertops are built in position. The form is built on the cabinets, concrete poured into it, then ground and polished on-site. The big advantage is no seams over very long runs.

## When to use which

Use **precast** for:

-   Standard kitchen countertops (most cases)
-   Vanities
-   Smaller bar tops
-   Spaces where finish quality matters most

Use **cast-in-place** for:

-   Long bar tops over 12 feet
-   Outdoor kitchen islands
-   Complex shapes that are hard to transport
-   Floor-poured surfaces (rare for countertops)

Most of our installs are precast — the finish control and reliability of shop work is better for typical residential kitchens. We discuss the right approach during the quote based on dimensions, location, and what matters most to you.

## Frequently Asked Questions

Is precast better? +

For most residential kitchens, yes — better finish control. Cast-in-place is better for long bar tops or outdoor surfaces.

Are there seams in precast? +

Yes, at slab joints. Modern installs minimize them with seamed joints or epoxy-filled lines.

Which costs more? +

Roughly comparable. Precast labor is in the shop; cast-in-place labor is on-site. Material costs are similar.
