Your countertop edges are the finishing touch that adds personal flair to your overall design theme. 

With many countertop edge profiles to choose from, you're sure to find the perfect style for your kitchen counter tops, kitchen island, outdoor kitchen, bathroom counter tops, wet bar or wine cellar. Or for something completely original, combine two different styles to create your own!

 Thickness of your countertop slab is also a consideration, so keep the following points in mind.
A 3cm slab provides a substantial profile that looks good with a variety of edge styles and is the preferred size to use. 

A 2cm slab is sometimes used, but the countertop can look rather thin. Because of this it is common to laminate the edge of a 2cm slab. 

This additional strip glued underneath the edge makes the countertop look thicker. 

However, it results in a seam that runs horizontally around the edge. 

In most cases this is not a problem and virtually unnoticeable, but the seam may be visible depending on the color and pattern of the granite, marble, travertine, limestone, etc. 

Darker countertop colors with more consistent patterns will "hide" a seam better than lighter countertops colors with lots of "movement" in their pattern. 

Unless your on a very tight budget, skip the 2cm and go with the 3cm slab. It's stronger and simply looks better.
