Dekton Worktops What is the Difference between 4 mm, 8 mm, 12 mm, 20 mm and 30 mm Dekton Worktops

What is the Difference between 4 mm, 8 mm, 12 mm, 20 mm and 30 mm Dekton Worktops

Mon, Jul, 2019 Maria Kairuz

As standard industry guidelines, Dekton worktops are available in different thicknesses – from slimmer to thicker slabs. Their thickness varies for different reasons, such as for serving as backsplashes, wall installations, flooring solutions or kitchen worktops.

The Thickness of Dekton Worktops

Dekton worktops are available in 4 mm, 8 mm, 12 mm, 20 mm and 30 mm thicknesses. However, each thickness level contributes to higher countertop value and better wear in highly functional areas.

According to industry experts, 30 mm thick Dekton slabs are expensive but provide long-term value compared to thinner slabs in terms of installation and durability. The 20 mm Dekton worktops are obviously thinner than 30 mm slabs; however, it is more affordable than the 30mm Dekton slabs, as less material is required for manufacturing 20 mm worktop slab.

On the other hand, 12 mm, 8 mm and 4 mm worktops are thinner respectively compared to 20 mm and 30 mm Dekton slabs. While the thinner slabs are equally appealing and give similar aesthetic appeal as the thicker slabs, the thinner versions are more vulnerable to cracks, chipping or scratches.

Edge Profile

The Dekton worktops are available in three different edge profiles:

  • Half Bullnose (Waterfall) or Bullnose Edge Profile

The Bullnose edge profile has a curved design, which is rounder than the single pencil edge. It appears to have a single but unbroken curve. This edge profile is suitable for thinner 4 mm and 8 mm Dekton worktops to have the more fluid, contemporary impression. 

The Half Bullnose (or Waterfall) edge profile is good for 12 mm or thicker worktops. It has a curvy shape at the top, but the bottom is flat, just like a waterfall and hence, named “waterfall” edge profile. 

  • Square Edge Profile

The Square profile looks great in both traditional and modern kitchens. It gives solid appeal and appearance to the worktops with simple and clean lines. When making a square edge profile, the designers still give it a slightly curvy touch at the top edges so that it doesn’t become quite sharp and increase the risk of injury. This edge profile looks brilliant on 12 mm or thicker worktops.

  • Single Bevel Edge Profile

The single bevel edge profile looks great on 20 mm and 30 mm Dekton worktops, giving a geometric layout to your countertops without messing with the clean lines. It has two sweeping archers on the top and bottom, creating the timeless impression that’s likely to become the focal point of your worktop. 


The thinner slabs (like 4 mm, 8 mm and 12 mm) are perfect to offer a sleek look to your kitchen countertop and may support various applications. Some contractors prefer thinner Dekton slabs for particular applications like backsplashes, fireplace surrounds, bath/shower, flooring or wall coverings. 

On the other hand, designers and homeowners opt for 20 mm and 30 mm worktops for their kitchen worktops, as well as other functions like upstands, splashbacks and window sills. Installing these thicker Dekton worktops ensures that you don’t have to buy additional material for vertical panelling or fabrication of these thicker slabs. 


The 4 mm, 8 mm and 12 mm worktops are cheaper than 20 mm and 30 mm Dekton worktops due to ease of installation and use of less material. Therefore, many homeowners and interior designers prefer them for different uses in their house.

On the other hand, the 20 mm Dekton worktops are cheaper than 30 mm worktops; however, these are quite similar in terms of functionality and resistance against chipping, cracking or any other type of damage. If 30 mm Dekton worktop is out of your budget, you can opt for 20 mm Dekton slab, as no one will be able to notice the difference between the two.

Which thickness level is suitable for which area of your house?

Not sure which thickness level of a slab is suitable for different areas of your kitchen? You must discuss your budget and options with an experienced professional fabricator to get a personal and up-close look at the thickness of your selected Dekton countertops. However, there are some fabricators who only work with a certain thickness of a worktop based on their personal preference or experience. They may find a certain thickness level better than the other. So, you must keep in mind the thickness parameter and speciality of the experts when selecting an installation professional.
