Traditionally, hex tiles came in patterns of white with black accents.
A border in black was common too.
The combination is still popular in traditionally-styled bathrooms, and continues to impart a clean, classic look.
Of course all white is just as timeless, and works in a variety of styles. Here it goes classic.
But it can do transitional...
... Or minimal and modern well too.
Mosaic hex tiles might be worth a try if you're looking for a more contemporary style. They can provide a subtle hint of color...
... Or make an impact in a bolder hue.
The natural striations and tones of marble become more apparent in smaller tiles, like these hexagonal ones.
The look is luxe and livable, as smaller tiles are less prone to cracks.
