Thassos White Marble Tile

Thassos White Marble is a white marble trim piece offered in Pencil Liner, Bullnose Liner and Liner Quarter Round formats. The stone takes light the way only real marble does, with movement and translucency a printed surface can only approximate. It finishes edges, transitions, and baseboards so the field tile ends with a clean line.

A white surface opens and brightens a room, bouncing light through bathrooms and smaller spaces where a darker floor would close them in. Pair it with warm wood and brushed brass for a soft scheme, or black fixtures for sharper contrast.

Marble is metamorphosed limestone, formed when heat and pressure recrystallize calcite into the veined, light-reflective stone quarried for centuries of architecture. Every tile is cut from natural blocks, so veining and tone vary from piece to piece, which is the material's signature rather than a defect. Marble stays cooler than the surrounding air, takes a high polish, and brings a depth of color that printed surfaces approximate but do not match.

Marble is a calcite stone and needs sealing at installation and roughly once a year after, depending on traffic. Wipe spills quickly, especially wine, citrus, and vinegar, which etch the surface on contact. Clean only with stone-safe pH-neutral cleaners; never use vinegar, bleach, or abrasive powders. Use walk-off mats at entries and felt pads under furniture. Install with white thinset to avoid bleed-through, and dry-lay tiles first to blend natural variation across the floor or wall.
