Premium Thassos White Greek Marble Tile | 6x12 x 3/8"

Experience the pinnacle of Mediterranean luxury with our 6x12 Thassos White Marble Tile. Mined from the historic island of Thassos, Greece, this marble is world-renowned for its brilliant, sugar-white clarity and high-reflectivity crystalline structure.

The 6x12 "large-format subway" size is a designer favorite for 2026, offering a modern twist on traditional tiling. Its elongated shape creates fewer grout lines, resulting in a cleaner, more expansive feel that makes even the smallest bathrooms or kitchens appear vast and radiant.

Why 6x12 Thassos is Trending

• Modern Geometry: The 6x12 ratio allows for versatile patterns, including Vertical Stacking (to add height to a room) or Offset Brick (for a classic yet bold look).

• Luminous Crystalline Surface: Unlike "cloudy" white marbles, Thassos contains natural crystals that catch the light, making it the brightest natural stone available.

• Superior Hardness: Thassos is a dolomite marble, making it denser and more durable than many other white marble varieties.

Pro-Installation & Maintenance

• White Thinset Required: To preserve the stone's translucency, you must use a high-quality White Polymer-Modified Thinset. Never use grey mortar.

• Grout Selection: For a seamless "infinity" look, use a Bright White unsanded grout. For a subtle architectural pop, a very light silver-grey is recommended.

• Sealing: Thassos is a premium investment. Apply a high-performance impregnating sealer (like Aqua Mix Sealer's Choice Gold) before grouting and annually thereafter.

• Daily Care: Clean only with pH-neutral stone cleaners. Avoid acidic household chemicals which can "etch" or dull the surface.

Frequently Asked Questions (FAQ)

Q: Can 6x12 tiles be used on floors? A: Yes. The 6x12 format is excellent for bathroom and residential floors. For wet areas like walk-in showers, the Honed finish is recommended for better traction.

Q: How many tiles are in a square foot? A: Exactly 2 tiles make up 1 square foot.

Q: Is "Thassos White" the same as "White Carrara"? A: No. White Carrara (from Italy) features grey veining and a "muddy" white base. Thassos (from Greece) is much whiter, more consistent, and has a sparkling crystalline texture rather than grey veins.

Q: Does it work with radiant floor heating? A: Exceptionally well. Thassos marble has great thermal conductivity and is fully compatible with electric and hydronic underfloor heating systems.
