20mm vs 30mm Quartz and Granite Worktop

Granite and Quartz both make first-rate and outstanding countertops. However, with several thickness options available, it becomes challenging for most homeowners to make the right selection.

Is it safe to use 20mm quartz or 30mm granite worktop? Which one is better – 20mm granite countertop or 30mm granite countertop? What is the cost difference between 20mm or 30mm granite and Quartz?

Although the answers to these questions depend significantly on personal choices, there are specific reasons to choose one over the other. So, let's take a look at some significant differences between 20mm and 30mm quartz and granite worktops, and how you can select one.

A lot of people prefer picking 20mm quartz kitchen countertops over other popular kitchen worktops. As a matter of fact, quartz worktops are usually available in 20mm thickness with multiple color options. Traditionally reserved for window sills, backsplash, and upstands, 20mm quartz countertops are becoming immensely popular among the homeowners.

On the other hand, granite worktops are readily available in 20mm and 30mm thickness options. These worktops offer the utmost functionality and are easy to maintain. So, if you’re looking for a natural stone with amazing features as your kitchen worktop, then 20mm or 30mm granite worktops could be an ideal choice for you.

When it comes to suitability, 30mm granite worktops are considered more suitable over 20mm granite kitchen countertops. Granite stone occurs naturally, and it contains fissures and natural veins. Therefore, thinner granite slabs are sealed and coated with a plastic mesh to prevent cracks and breakages.

It means that buying 20mm granite over 30mm granite worktops will run the risk of cracks over time. As a matter of fact, thicker natural granite worktops are much better in terms of tensile strength with minimal weak points.

Conversely, quartz worktops are engineered stones, which mean that their durability, color, and consistency can be controlled on every slab. Although 20mm quartz kitchen countertops are thinner, their durability and tensile strength are much superior as compared to 20mm granite worktops. Quartz slabs make ultra-compact surfaces, and unlike granite worktops, they do not contain any weak points or fissures.  

Cost is one of those leading factors that could probably influence your selection of worktop for your home kitchen. When it comes of granite worktops, 20mm granite worktops are 8 to 10% cheaper than 30mm granite slabs.

Similarly, 20mm quartz kitchen countertops are cheaper than 30mm quartz slabs. The percentage difference in the prices of quartz worktops may vary according to various quartz brands and color patterns.

Well, if you're willing to give a more streamlined look to your kitchen area, then it is safe for you to buy 20mm granite or 20mm quartz worktop for your home kitchen. Although, the 20mm and 30mm quartz both are well suited as kitchen worktops, it is imperative that you pick the right color pattern, and design to match your kitchen's existing color schemes. If you're not able to find the right color pattern, then you can opt for naturally designed granite worktops for refining the looks of your contemporary kitchen.
