Square tiles bring the most classic format in tiling to a kitchen, used across an enormous range of styles from period to thoroughly contemporary.
For the floor, large format porcelain is the practical choice, available in wood, stone, cement, and plain effects, and easy to wipe clean through daily use. A square tile also works brilliantly on a splashback or surround, and turning it forty-five degrees for a diagonal layout brings real character to a smaller kitchen.

A diagonal layout also brings real character to a smaller kitchen floor, making the room feel a touch more spacious.
