How Thick is Cambria Quartz Countertop?

Typical Thickness of Cambria Quartz Countertops

The standard thickness for Cambria quartz slabs is 1.25 inches, or just over 3cm. This thickness is suitable for most residential countertop applications, including kitchen countertops and bathroom vanities.

Some of the benefits of a 1.25 inch thick Cambria quartz countertop include:

  • Provides ample durability and strength to withstand daily use
  • Resists cracking, chipping, scratches better than thinner options
  • Meets requirements for standard countertop installations
  • Maintains stability without need for extra support

While 1.25 inches is the most common thickness, Cambria does offer additional thickness options:

1.5 inch Thick Cambria Quartz

For homeowners who want extra durability and weight, the 1.5 inch slabs provide an upgraded thickness. The additional 0.25 inches gives the countertop a more substantial feel and can be beneficial for certain applications.

2 cm Thick Cambria Quartz

Cambria’s thinnest quartz option measures 2cm or slightly less than 1 inch. The slim profile can be useful for applications where weight is a concern or thin edges are desired. However, the thinner quartz is more prone to cracking/chipping and cannot span as far without seam supports.

Custom Thickness Options

In addition to their standard thicknesses, Cambria can customize quartz slabs to your exact specifications. Though rare, some designers opt for an ultra-thin 1 inch profile or an extremely thick 2 inch option. Keep in mind customized slabs usually increase lead times and costs.

Factors That Determine Cambria Quartz Thickness

When selecting the ideal thickness for your Cambria countertop, consider factors like:

  • Usage – High traffic kitchen areas may warrant thicker quartz for added durability. Bathrooms and wet bars can utilize thinner profiles.
  • Span – Long spans between supports require thicker slabs to prevent sagging. Standard bar size spans usually don’t need more than 1.25 inches.
  • Overhangs – Increased overhangs, such as for waterfall edges or extended bar spaces, often require thicker quartz for proper support.
  • Appearance – Personal style preferences may dictate thickness. Some desire the graceful look of thin quartz, while others prefer the bold appearance of thick slabs.
  • Budget – Thicker Cambria slabs cost more due to increased materials. Prioritize longevity and durability or opt for standard thickness to save on costs.

Typical Applications for Cambria Thicknesses

Here are some common uses for the various thicknesses of Cambria quartz:

  • 2cm (0.8 inches) – Bathroom vanities, niche wall panels, fireplace surrounds, mosaic backsplashes
  • 1.25 inches – Kitchen countertops, islands, bars, laundry rooms, wet bars, hearths
  • 1.5 inches – Heavy usage kitchen countertops, commercial projects, reception desks
  • Custom Thickness – Accent walls, exterior cladding, stair treads, outdoor kitchens

Installing Different Thicknesses of Cambria Quartz

The installation process doesn’t change much for the various thicknesses of Cambria quartz. The countertops are all installed using the same basic methods:

  • Careful measurements are taken
  • The substrate is prepared
  • Slabs are cut to specifications
  • Cambria quartz is secured to the substrate using adhesive
  • Seams are tightly bonded; edges finished and polished

The only differences you may notice with thicker slabs is the need for more installer muscle when maneuvering them and potentially longer curing times for adhesives. Lighter 2cm slabs are much easier to handle.

Is Thicker Cambria Quartz Better?

When it comes to Cambria countertops, thicker is not necessarily better across the board. The optimal thickness depends on your specific project needs and application.

The 1.25 inch option provides the best balance of strength, cost-effectiveness, and ease of installation for most standard installations. Only certain applications, like heavy commercial use or substantial overhangs, require thicker quartz for structural performance.

Regardless of whether you choose a slim 2cm profile or a substantial 1.5 inch thickness, you can rest assured that Cambria quartz will provide long-lasting beauty and durability for your home. Their quartz engineering ensures strength and quality at any thickness.
