What’s The Standard Granite Worktop Thickness?


When you’re designing a new kitchen, there are so many different elements to think about and it can be overwhelming making so many decisions. You have to consider which kitchen design to use, what the layout will be, and which colours will suit your interior design style. One thing you don’t want to have to worry about is how thick your granite worktop should be. Luckily, we’re here to help you decide. 


Choosing the right worktop material

In order to make an informed decision about how thick your worktops should be, you should have an idea of what worktop material you want. There are so many different types of work surface materials you can choose from. From natural stone such as granite worktops, to engineered stone, such as quartz, there’s something for everyone’s tastes!


No matter what material you go for, a general rule of thumb is that the thicker the worktop, the more durable and practical it is. 


Plus, a high-quality kitchen worktop will generally last longer than a cheaper material, such as laminate worktops.


Granite worktops are a great choice for a kitchen countertop because they’re resistant to most forms of damage, are easy to clean, and are more affordable than other stone worktops. They also add character to your kitchen space!


Choosing the right size of a granite worktop

Granite slabs are rarely larger than 3 metres, but they can be cut, shaped, and fitted to create a smooth look over a large surface area.


As the customer, you have autonomy over the shape and size of your new worktops. So, if you opt for granite worktops, the material is cut into slabs that are then tailored to your preference by your supplier.


At Mo’s StoneX, we manufacture and supply bespoke worktops, tailoring them to meet your needs and your kitchen designs. If you want to transform your kitchen, we’re here to help. But how are you meant to know what the most suitable granite worktop thickness is?


How thick are standard granite worktops?

The thickness of stone worktops differs from the thickness of wood worktops and laminate worktops. The latter are often between 38mm to 40mm in thickness whereas the standard thickness of stone worktops is 30mm. Thinner 20mm stone worktops are also available, but it’s only recently that more kitchen styles are being designed at 20mm because demand has increased.


Should I choose a 20mm or 30mm granite worktop thickness?

The thickness of your granite kitchen worktop ultimately depends on personal preference. Sleek, modern kitchens aim to maintain their minimalist appearance with a thinner worktop, however, their durability sometimes isn’t as long-lasting as thicker countertops.


Advantages of 20mm Granite Worktops

  • Granite is a durable and tough material. The thinner the stone, the less tough it is. But granite is naturally durable and is still a reliable material even at a 20mm thickness.
  • It’s a lighter weight than granite at a 30mm thickness! This may reduce the costs of installation. It will also put less strain on the kitchen cabinets and units below, meaning they will last longer.
  • It creates an effortlessly sleek and modern look in any space. They’re also perfect for splashbacks and act as a luxurious addition to contemporary kitchen spaces.
  • They’re easily customisable because there’s less material to manipulate.


Disadvantages of 20mm Granite Worktops

  • Not all granite kitchen worktop designs are available in 20mm thickness and they have to be considered on a slab-by-slab basis. So, your dream granite kitchen worktop in your preferred style and colour may not be available in 20mm.
  • There’s a risk of cracks appearing at weak points within the natural stone. This can happen in areas where the granite has been cut to fit around hobs and sinks.


Advantages of 30mm Granite Worktops

  • It is a stronger and more durable option. It’s a great material for busy areas in the home because it can withstand everyday wear and tear.
  • There is less chance of your worktop cracking in the 30mm than the 20mm worktop option because it’s thicker and tougher.
  • A thicker work surface can withstand more pressure, which is ideal for food preparation areas. 
  • 30mm worktops provide an alternative option if your kitchen style isn’t available in a 20mm thickness.
  • They’re a bold, distinctive addition to your kitchen space. Their chunkier look is fashionable and stunning, as well as practical.


Disadvantages of 30mm Granite Worktops

  • 30mm worktop options are more expensive than 20mm worktops, but they are more likely to stay in better condition for longer. Yet, granite prices are generally dropping because of the rising popularity of quartz kitchen worktops.


What thickness of granite worktop should I choose?


Although there are many benefits of both 20mm and 30mm granite worktops, what’s important is how the thickness will suit the aesthetic of your kitchen and design tastes. If you’re looking for something to complement a modern, minimalist appearance, 20mm worktops may be the most suitable choice. 


If you’re choosing based on purely practical elements, the 30mm granite worktop is the best option. You don’t have to worry about possible cracks and not placing as much pressure on the surfaces.
