About Thassos White Marble Octave with Black Dots Polished Mosaic

Material Education

Thassos marble is a pure, snow-white crystalline stone quarried from the Greek island of Thassos in the northern Aegean Sea. Renowned worldwide for its exceptional whiteness and luminous, glass-like brilliance, it contains virtually no veining — just a clean, sparkling crystalline matrix that reflects light beautifully. The black dot accents in this mosaic are crafted from Nero Marquina, a deep jet-black marble sourced from Europe, providing a dramatic tonal contrast.

As a genuine natural stone, subtle variation in crystal grain size and occasional faint mineral inclusions are natural characteristics of authentic Thassos marble, ensuring each sheet is uniquely its own.

About this mosaic: Octagon chips are pre-arranged with small black marble dot inserts in the classic octagon-and-dot pattern, mounted on a mesh-backed sheet for fast, consistent installation — the grid alignment is already done for you.

Design & Inspiration

The striking contrast of pure snow-white Thassos against jet-black Nero Marquina dots pairs beautifully with polished chrome or matte black fixtures, white oak cabinetry, and crisp white grout for a timeless, high-contrast aesthetic. This mosaic is equally at home in classical Victorian-inspired bathrooms, sleek contemporary spa retreats, and refined transitional interiors.

The octagon-and-dot pattern is one of the most enduring geometric tile formats in design history, lending a sense of elegant structure and visual rhythm to floors and walls without feeling busy. The polished finish amplifies Thassos's legendary luminosity, making even smaller spaces feel open, bright, and expansive.

Popular design combinations: pair with honed Carrara marble field tiles on the walls, brushed nickel fixtures, and white oak vanity for an effortlessly sophisticated bathroom. Explore the full Thassos White collection for coordinating sizes, and browse more marble mosaics for complementary looks.

Thassos White Marble is quarried from the Greek island of Thassos and is celebrated as one of the purest, most brilliantly white natural stones in the world — its crystalline structure gives it an almost luminous, glass-like glow that no other white marble can replicate. This mosaic pairs that iconic Thassos white with deep black Nero Marquina marble dots for a timeless octagon-and-dot composition.

Each chip is polished to a high-gloss finish that intensifies the contrast between the snow-white octagons and the jet-black dot inserts, creating a crisp, jewel-like surface with strong visual impact. Chips arrive factory-arranged on mesh backing, dramatically reducing layout time and ensuring perfectly consistent spacing throughout your installation.

This mosaic is ideal for bathroom floors, shower floors, kitchen backsplashes, and powder room accent walls where its classic geometric pattern can take center stage. Because this is a clearance or specialty item, we recommend ordering a sample first to confirm the color matches your space, and ordering 10–15% overage to account for cuts and future repairs.

Free Shipping: As a mosaic, 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 an exceptionally pure, low-porosity marble, but its brilliant white surface will show any staining immediately — sealing is strongly recommended. Apply a premium penetrating stone sealer before grouting and reseal every 6–12 months in wet areas such as showers and bathroom floors. In kitchen applications, reseal annually or whenever water stops beading on the surface.

Cleaning: Clean with a pH-neutral stone cleaner or a diluted mild dish soap and warm water. Never use acidic cleaners (vinegar, lemon-based products, or grout haze removers containing acid) as they will etch the polished surface and cause permanent dull spots on the white marble. Blot spills immediately — especially coffee, wine, and citrus — to prevent staining the bright white field.

Installation: Always use white polymer-modified thinset mortar to avoid any gray bleed-through that could discolor the translucent Thassos chips. Use non-sanded grout for joints under 1/8 inch to prevent scratching the polished surface during grouting. Back-butter each sheet lightly in addition to spreading thinset on the substrate for maximum bond, and align mesh sheets carefully before setting to maintain consistent dot spacing throughout the field.

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

Ordering a sample before a full purchase is always recommended, especially for natural stone.
