Circular tiles are a properly unusual format, breaking up the straight lines that dominate most rooms and adding real visual interest wherever they are used. They work beautifully as a splashback, across a flowing open space, or as an accent within a predominantly square or rectangular tiled area.
This shape earns its keep as a feature rather than a full-room commitment: a fireplace surround, a bathroom wall, or a kitchen splashback are all places where a circular tile can do real work. Placed strategically, it draws the eye and gives a scheme a point of real character that a straight-edged tile simply cannot offer. A circular tile also pairs wonderfully with a plain, rectangular tile nearby, letting the shape stand out rather than competing with too much pattern around it.
