Biyusai 4x4 is the square-format mosaic in INAX's Biyusai collection, made of glazed porcelain tiles with a distinctly Japanese earthenware texture and a deep, reflective glaze. The square grid gives a wall a clean, classic structure with rich color and subtle variation.

Like the rest of the Biyusai collection, the 4x4 is built to be combined. It comes in a range of colors and works alongside the other Biyusai shapes and sizes, so designers can mix formats to build custom patterns and effects. It's available in White, Moss Green, and Navy Blue.

As a glazed porcelain, Biyusai 4x4 is durable, water-resistant, and easy to clean, which makes it well suited to feature walls, backsplashes, and bathroom or kitchen walls. The navy blue is also rated for pool applications. Natural variation in color and glaze from tile to tile is part of its character.
