Frequently Asked Questions (FAQ)

What makes Thassos White marble different from Carrara marble?

While Carrara marble is known for its grey veining, Thassos White is prized for its lack of veining and its pure, brilliant white color. It is considered one of the most luxurious and "cleanest" white marbles in the world.  

Where is a quarter-round trim typically used?

Quarter-rounds (also known as "pencil liners" or "beads") are used to finish the raw edges of a tile installation. They are perfect for turning corners in a shower, edging a soap niche, or capping the top of a wainscot wall.  

Does Thassos marble require special care?

Like all natural marble, Thassos is porous. We recommend using a high-quality penetrating sealer upon installation to protect against staining. For daily cleaning, use a pH-neutral stone cleaner and avoid acidic substances like vinegar or lemon juice.

Can this trim be used in wet areas?

Yes. Thassos White marble is excellent for showers, bathrooms, and kitchen backsplashes. Because it is a natural stone, ensuring a proper seal is key to long-term performance in wet environments.  

Is the color consistent across all pieces?

Thassos is known for being the most consistent white marble available. However, because it is a product of nature, slight crystalline variations may occur, which adds to the stone's organic beauty.
