The Honed Thassos White Marble Bias Border with Black Dots showcases one of the world's most coveted natural stones — pure crystalline white marble from the Greek island of Thassos — shaped into a sleek 2×12 decorative trim piece. The inlaid black dot pattern introduces a graphic, jewel-like accent against the luminous white ground, making this border a statement detail in any refined interior.

The honed finish delivers a smooth, matte-to-satin surface that softens the marble's natural sparkle into an understated elegance, reducing glare while still conveying depth and luxury. The bias (diagonal) profile adds architectural dimension and visual interest at transitions, niches, or border runs, and the piece arrives ready to set with standard white thinset mortar.

This border is ideal for bathroom and shower wall accents, mirror frames, fireplace surrounds, and backsplash perimeters — anywhere a polished decorative line is desired. As a clearance or specialty trim item, we recommend ordering a sample to confirm color match with your field tile, and purchasing a modest overage to account for cuts. Seal upon installation and maintain regularly to protect the honed surface in wet environments.

Free Shipping: As a molding, this product qualifies for free curbside shipping on orders over $1,999 within the continental U.S. Orders below that threshold ship at standard rates calculated at checkout.

Processing & Delivery: Orders are processed within 2–3 business days. Large orders ship via LTL freight — curbside delivery only. An adult must be present to sign for delivery. Estimated transit: 2–10 business days after shipment.

30-Day Returns: Uninstalled tile may be returned within 30 days of delivery. Inspect all tile carefully before installation — installed tile cannot be returned or exchanged. Samples are final sale.

Exclusions: Free shipping does not apply to Hawaii, Alaska, U.S. territories, or international addresses. Additional charges may apply for remote delivery areas.

Sealing: Thassos White is a dense but highly porous white marble that is exceptionally susceptible to staining — seal this border with a penetrating impregnating sealer immediately upon installation. In wet areas such as showers, reapply sealer every 6–12 months. The pure white background makes any unsealed staining highly visible, so consistent sealing is essential.

Cleaning: Clean with a pH-neutral stone cleaner diluted in warm water and a soft cloth or sponge. Never use acidic cleaners (vinegar, citrus-based products), alkaline degreasers, or abrasive pads — acids will etch the honed surface and acidic residue is especially visible on bright white marble. Wipe spills — especially coffee, wine, and oils — immediately to prevent absorption.

Installation: Use white polymer-modified thinset mortar to avoid any gray show-through on the translucent white stone. Butter the back of each piece fully to ensure complete contact and prevent lippage. Use non-sanded grout in a bright white or matching tone for any joints. Align the bias angle carefully during layout to maintain a clean, consistent diagonal line across the installation.

Important: Inspect all tile before installation. Variations in color, veining, and texture between pieces are natural characteristics of genuine stone — not defects. Order 10% overage for cuts, waste, and future repairs. Tile & Mosaic Depot specialists are available M–F 8:30AM–5PM PST at 855-797-8453.

Product & Installation Guidance

Natural stone is a product of the earth — every piece is one of a kind. A little planning ensures your finished installation looks its best and lasts for decades.

Natural Variation
Color, veining, texture, shade, movement, finish, and sizing vary from piece to piece. Product photos and samples are a general reference and may not match the exact material you receive. These variations are inherent characteristics of natural stone — they are part of its beauty, not defects.

Before You Install

  • Order roughly 10% extra to allow for cuts, waste, and future repairs.
  • Blend tiles from multiple boxes as you work to achieve the most natural, balanced appearance.
  • Dry-lay and inspect the full layout before setting a single tile.
  • Installation constitutes full acceptance of the product, so review everything carefully first.

Sealing & Care
Natural stone should be sealed with a quality penetrating sealer before and after installation, and re-sealed periodically in wet or high-traffic areas. Clean only with a pH-neutral stone cleaner; avoid acidic products, bleach, vinegar, and ammonia, which can permanently etch the surface. Outdoor installations may weather or change tone over time with exposure.

Responsibility
Tile & Mosaic Depot is not responsible for improper installation, labor costs, substrate conditions, product misuse, or damage from improper handling, sealing, maintenance, or harsh chemicals. No claims, returns, or replacements can be accepted on installed material.

California Proposition 65: Some natural stone products contain substances known to the State of California to cause cancer or reproductive harm. For more information, visit www.P65Warnings.ca.gov.

Order a Sample First

Seeing real stone in your own space — under your own light, beside your own finishes — is the best way to buy with confidence. We make it easy and affordable.

How It Works
Samples are just $7.99 each with free shipping, and they ship in 1–3 business days. Sizes vary by material and availability, typically ranging from 3"×3" up to 8"×8". Exact dimensions aren't guaranteed, but every sample is cut from the same material you'll receive in a full order.

What a Sample Shows
Samples help you evaluate the general color, texture, finish, and overall character of a product before committing to a full order. Because natural stone varies from piece to piece, your sample is representative — it may not capture the complete range of variation across an entire lot. For current lot photos, just ask our team.

Good to Know

  • Samples are final sale — non-returnable and non-refundable.
  • Ordering a sample before a full purchase is always recommended, especially for natural stone.
  • Planning a larger or custom quantity? Contact us for a tailored quote.
