A luminous, marble-kissed glass that elevates every wall

This glossy white glass tile washes walls in an ethereal glow, its soft marbleized veining adding quiet movement and sophistication. I love the slender 3x12 silhouette—timeless yet fresh—perfect for a refined herringbone or a serene stacked layout. Pair it with brushed nickel fixtures and a pale gray grout for a whisper of contrast. It’s an effortless path to a luxe, spa-like backdrop.
