Does anyone have experience of marble floor tiles in their kitchen? We are in the process of extending and re-fitting our kitchen, and need to choose floor tiles this weekend (we have been deliberating for weeks!). We have decided to go for white carrara marble worktops (against grey hand-painted units). We like the idea of having the floor tiles match the worktop. Is a marble kitchen floor a nightmare? Polished or honed? It's a typical young family kitchen, high traffic. Thanks for your thoughts!
