Where are Allen & Roth Quartz Countertops Manufactured?

An Overview of Allen + Roth Quartz Countertops

Allen + Roth is a private label brand sold exclusively at Home Depot stores. The quartz countertops are made from engineered stone, consisting of 90% ground natural quartz combined with resins and pigments. This manufacturing process creates a hardy non-porous surface that resists scratches, stains, and heat.

Allen + Roth offers a wide range of unique quartz countertop colors and patterns. Popular options include white marble looks, grays, and blacks with veining in tones like gold, silver, and copper. The wide color palette allows for creative designs that are on-trend with modern decor styles.

The brand’s quartz slabs come with warranties up to 15 years for residential installations. This provides peace of mind for durability and performance over time.

Where Allen + Roth Sources its Quartz Material

Allen + Roth does not actually manufacture its own quartz material. Instead, it sources pre-made quartz slabs from leading global suppliers of engineered stone.

The brand’s parent company, Home Depot, has a partnership with cosmetic quartz manufacturer Cambria. Much of Allen + Roth’s quartz is sourced from Cambria’s factories in the United States and Canada.

Allen + Roth also sources quartz material from other major suppliers like LG and Caesarstone. LG has factories in South Korea and India. Caesarstone manufactures its quartz slabs in Israel and the United States.

So while the final countertops are assembled and sold under the Allen + Roth name, the raw quartz material is sourced globally from a few large providers.

How the Quartz Slabs Are Transformed into Countertops

Once the quartz slabs arrive from manufacturers like Cambria and LG, they go through a finishing and fabrication process before becoming complete countertops.

The specific steps involved include:

  • Inspection: The quartz slabs are inspected for any defects or damage. Slabs that pass inspection move to the next step.
  • Cutting: Computer-controlled machines precisely cut the slabs to the exact dimensions required for each custom countertop order. Modern waterjet cutters streamline this process.
  • Shaping and Polishing: Shaping machines trim and polish the cut edges and corners of each slab. This prepares the edges for seamless joining.
  • Assembly: For longer countertops requiring seams, the cut quartz pieces are adhered together using special epoxy glue.
  • Finishing: The final step is applying the finish, which involves buffing and polishing each quartz countertop. This brings out the smooth glossy surface and vibrancy of the colors.

Quality Control and Installation

Throughout the fabrication process, Allen + Roth quartz countertops go through rigorous quality control checks. This ensures they meet durability and performance standards.

Once complete, the pre-fabricated countertops are packaged and shipped out to Home Depot stores for purchase. Professional installers then handle the installation into customers’ homes.

Proper installation is key to ensuring a seamless fit and long-lasting durability. Home Depot provides a list of qualified independent installers to choose from when buying new quartz countertops.


While Allen + Roth collaborates on design, the actual quartz material in their countertops originates from leading engineered stone suppliers. Cambria, LG, Caesarstone, and other manufacturers provide quality quartz slabs that then go through careful fabrication and quality control under the Allen + Roth name. This results in beautiful, durable countertops that bring high-end style into homes. With the wide range of colors and patterns available, it’s easy to find Allen + Roth quartz countertops that match your unique decor.
