When planning your kitchen worktop project one detail that often gets overlooked is the thickness of your countertop. It might sound small compared to choosing colours or appliances, but the right thickness makes a huge difference to both style and durability.
And if you’re investing in a bespoke stone worktop for your home, getting this detail right is key to achieving a flawless finish.

Bespoke Options for Your Home
Choosing bespoke stone worktops allows you to go beyond the standard options. Many homeowners in are now requesting custom thicknesses to suit their design preferences:
-
Thicker Profiles (40mm+) – Create a bold, statement look.
-
Slimline Profiles (12mm–15mm) – Popular with modern, minimalist interiors.
-
Waterfall Edges – Extend the worktop down the sides of cabinets for a seamless finish.
A skilled stone fabricator can help you achieve these bespoke designs while ensuring structural integrity.
Things to Consider Before Deciding
When choosing the right thickness for your countertop, think about:
Cabinet Strength – Thicker stone means more weight. Ensure your units can support it.
Kitchen Style – Modern kitchens often lean towards slimmer worktops, while traditional kitchens suit chunkier profiles.
Budget – Thicker slabs use more material and can increase costs.
Practical Use – If your kitchen is busy with lots of cooking, a sturdier option may be better.
