The previous owners of our house didn't put any splashback in the kitchen. It's just a painted wall with glossy Ikea cabinets. The paint is not wipeable and already looks dreary. As it is a northfacing room but with a huge window and very light I am thinking of fixing a thin rectangle of marble across. The wall does have 2 double sockets which I want to keep. What is the best place to buy this piece of marble and also have sockets cut into it? Or is it better to get marble tiles? Thanks a lot.
