18x18
The 18×18 is a timeless large-square format that brings a clean, generous look to natural stone floors and walls. Genuine marble, travertine, and limestone in an 18×18 square — covering ground with fewer grout lines for a calm, seamless surface.
Why choose 18×18
The generous 18×18 square covers more ground per tile than a 12×12, meaning fewer grout lines and a cleaner, more open feel — while staying a versatile, easy-to-install size. It's a classic choice for natural stone floors, showers, and feature walls, where the larger format lets the stone's natural color and veining flow across the surface. Set in a straight grid for a crisp look or on a diagonal to make a room feel larger.
Marble
Honed and polished marble in whites, beiges, grays, and veined varieties.
Travertine
Warm, earthy travertine in honed, tumbled, and brushed finishes.
Limestone
Calm, soft-toned limestone for floors, walls, and outdoor spaces.
Honed & Polished
Smooth matte or glossy refined surfaces for elegant interiors.
Tumbled & Brushed
Rustic, slip-resistant textures for a weathered, organic look.
Large Square
Fewer grout lines and a clean, open feel across any floor.
Care & install: These are natural, porous stones — seal them and clean only with pH-neutral products, avoiding acidic cleaners that etch stone. A level substrate helps large-format tile lie flat and minimizes lippage. Order a sample to see the color and finish in your own lighting, and blend tiles from multiple boxes during installation.
