Thassos White and Blue Celeste Marble Mosaic Tile 12x12 Sheet

Bright, clean, and quietly luxurious, the Thassos White and Blue Celeste marble mosaic brings gallery-white stone and calming blue together on one 12x12 sheet. It is the kind of quiet detail that makes a bathroom feel custom, not off-the-shelf.

This honed marble mosaic pairs milky Thassos white with soft blue celeste in a crisp geometric layout, and the matte honed finish keeps the stone smooth and glare-free. As natural marble, every sheet carries its own faint veining and tone shifts, so treat that lot-to-lot variation as character rather than a flaw. Because marble is porous, plan to seal the tile before use and reseal periodically to guard against stains and moisture.

It shines as a shower accent band, a vanity backsplash, or a framed niche where the polished blue and white stone can catch the light. The palette leans coastal, so it suits a bright, breezy Florida bath beautifully.

Want to see the veining in person? Order a single sheet as a sample and live with it on your wall for a few days before you commit to the full order.
