Granite Worktops

A luxurious and unique product. Granite is a great choice for those who love the natural beauty of real stone.

Granite is a natural stone that is formed over the course of several million years during a process in which magma slowly cools and crystalises at high temperatures deep inside the earth, before finally reaching the Earth’s surface. This stone is then mined, treated and polished before being installed in your home!

At Portman Stone we have a collection of stock granites that you can view at our showroom. We would always recommend viewing the actual slabs that will be used for your worktops before proceeding as the nature of the product means that one slab can look completely different to another in the same material.

We use multiple high quality granite suppliers who source their natural stone from all across the globe.
