Thick or Thin: Your Ultimate Guide To Choosing Between 20 mm And 30mm Worktops

By: Alan Sep 29, 2025 0 Comments

Planning a kitchen revamp? While material is crucial, the thickness of your worktop can significantly impact your kitchen’s look, durability, and cost. The most common options—20 mm and 30 mm worktops —offer unique benefits. So, how would you choose the best among them? Let’s walk you through them so you can make a smart and stylish choice that best fits into your space.

20 mm or 30 mm: Which Thickness Is Best Suited For Your Kitchen?

The standard sizes are ideal for both residential and commercial kitchens. However, making a choice that resonates with the other aspects of your kitchen may be difficult for you. Consider the following factors before making the final decision.

1. Style Of Your Kitchen

Does your culinary space symbolise a modern or a traditional look?  Well, the thickness of your worktop has a lot to do with the look of your cooking area. The 20 mm worktops are thinner slabs that give a sleek appearance, ideal for minimalist and contemporary kitchens. A 30 mm countertop is thicker with a bold and luxurious look that would fit perfectly into a classic cooking area.

2. Usage Of Cooking Space

Do you have a high-traffic kitchen that seems busy all day long? If yes, the 30 mm worktop might seem a perfect choice considering its extra durability and resistance to wear and tear. In contrast, a 20 mm countertop is sufficient for moderate-level cooking. So, accordingly, pick up the best one that suits your lifestyle.

3. Budget

How much are you willing to shell out for your kitchen renovation? Well, your choice also significantly depends on it. For cost-conscious customers, 20 mm worktops are best due to their low pricing. The 30 mm countertops might come at a higher price due to their size and weight, but their durability and long-term value justify it.

4. Cabinet Strength

Believe it or not, the selection of your countertops does depend on the cabinetry you have. For a light or older kitchen cabinet, 20 mm countertops are good to go due to their easy installation process. However, a 30 mm worktop does require a strong well-supported closet to handle the extra weight.
