What is overage?

Overage is a safety to ensure you have enough tiles required for your project. Overage also ensures you have extra tiles to cover you in the event of human error during installation, such as breakages, and so that you can store spares for future use should tiles become damaged over time. This is particularly important as tiles can be discontinued, making it a challenge to match if you don’t have spares of the originals.
