2cm vs. 3cm which thickness is right for my project?

2cm vs. 3cm which thickness is right for my project?

When constructing a new kitchen or bathroom, you are confronted with lots of choices, options, colors, finishes, and styles this all might seem overwhelming. One of those choices is what countertop thickness to choose. In the stone industry, there are 2 primary options, 2cm (3/4”) or 3cm (1-1/4”). By using 3cm stones, edge profiles do not have seams like laminated 2cm edges. This eliminates non-matched laminated edges.

  • 2cm laminated edge installation requires plywood underneath the stone to raise the countertops above the drawer opening.
  • Laminated 2cm edge profiles only look thick at the edge. Undermount sink cut outs still show 2cm thickness
  • 3cm edges and cutouts will have the same thickness
  • Fabrication and installation costs are typically lower with 3cm

Note: There are some instances where 2cm with the plywood sub-top under the stone is better. One main reason to consider is leveling. If you are keeping existing cabinets that may have become unleveled throughout the years it is best to use the plywood sub-top so that it can be leveled and your new countertop is installed level. In these cases using 3cm stone can be challenging as the 3cm stone does not have the additional piece laminated to the edge so if shims are needed to level the 3cm stone it can create gaps between the cabinet frames and the stone that would need to be covered by trim molding.

** Not all stones are available in both thicknesses. But in comparison, utilizing 3cm stone when possible will give the best results for longevity and durability.

Notice the additional piece added to the 2cm, this creates a seam in the front of the edge profile.
