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.

Why Order a Sample
A screen can't show you how Calacatta veining reads under your kitchen lights or how a porcelain finish sits next to your cabinet color. A sample can. It's the single best way to buy stone or porcelain tile with confidence — and the cheapest mistake you'll ever avoid.

How It Works
Samples are $7.99 each. Samples ship free and leave our warehouse within 1–3 business days. Sizes vary by material and availability — typically 3"×3" up to 8"×8" — and every sample is cut from the same material stocked for full orders.

What a Sample Shows
Color, texture, finish, and overall character. Because natural stone varies piece to piece, one sample represents the material but can't show the full range of a lot. Porcelain samples are highly representative of the production run. Want to see the current lot before you commit? Ask us — we'll send photos.

Good to Know

Samples are final sale — non-returnable and non-refundable.
We recommend sampling before every full order, especially for natural stone.

Talk to a Specialist
Our stone and tile specialists will help you narrow it down. Call (855) 797-8453 or email sales@tileandmosaicdepot.com, Monday–Friday, 8:30 AM–5 PM PT.

How Your Order Ships
In-stock orders leave our warehouse within 2–3 business days. Stone, porcelain, and mosaic ship on a pallet via scheduled LTL freight and arrive 2–10 business days after dispatch, depending on destination. You'll get tracking and the carrier's name by email the day it ships.

Freight Delivery — What to Expect

The carrier calls you first. Every freight delivery is by appointment. Expect a call or text to set a window before the truck is dispatched.
Curbside delivery. The driver unloads to the curb or driveway. Freight does not include carrying material indoors or into a garage — plan for a helper or a hand truck.
Someone 18+ must sign. Inspect the pallet before signing. Note any damage, shortage, or broken shrink-wrap on the delivery receipt — this is what makes a claim valid.
Truck access. The address must be accessible to a full-size freight truck with enough space to unload.

Free Shipping
Free curbside freight on qualifying mosaic and molding orders over $1,999 in the continental U.S. Field tile, porcelain, and other product types ship at freight rates shown at checkout. Not available to Hawaii, Alaska, U.S. territories, or international addresses.

Damage & Shortages
Report within 3 calendar days of delivery with photos of the pallet, packaging, and affected pieces to sales@tileandmosaicdepot.com. Verified claims are covered. Shortages of 1–5 pieces are refunded rather than reshipped — which is why we recommend ordering 10% overage.

30-Day Returns
Uninstalled tile in full, unopened boxes may be returned within 30 days of delivery. Return freight is paid by the customer. Partial boxes, opened boxes, installed material, and samples are final sale.

Questions Before You Order?
Call (855) 797-8453 or email sales@tileandmosaicdepot.com, Monday–Friday 8:30 AM–5 PM PT. If you're unsure about freight access at your address, ask us before checkout — we'll flag anything that could hold up delivery.

Natural Variation
Quarried stone varies in color, veining, shade, movement, and finish from piece to piece and from lot to lot. Screen photos and samples show the range, not the exact tile you'll receive. Variation is the nature of the material and is never grounds for return. Porcelain is far more consistent, but shade and pattern can still shift between production runs — buy your full quantity in one order.

Before You Install

Order 10% overage. Covers cuts, breakage, and spares for future repairs. Reorders may not match in tone or lot.
Inspect every piece before setting. Pull from all boxes, blend, and dry-lay the full area. Installation is acceptance — no claims are honored once tile is set.
Hire a qualified installer. Natural stone and large-format porcelain require experience with the material. Your installer is responsible for substrate, setting materials, and method.

Sealing & Care
Natural stone should be sealed with a penetrating sealer and re-sealed periodically in wet and high-traffic areas. Clean with a pH-neutral stone cleaner only — vinegar, bleach, ammonia, and acidic cleaners etch marble, limestone, travertine, and onyx permanently. Porcelain does not require sealing. Outdoor stone weathers and shifts in tone over time; this is expected.

Responsibility
Tile & Mosaic Depot supplies material only. We are not responsible for installation, labor costs, substrate conditions, setting materials, product misuse, or damage from handling, sealing, maintenance, or chemicals. No claims, returns, or replacements are accepted on installed material.

California Proposition 65
Some natural stone and porcelain products contain substances known to the State of California to cause cancer or reproductive harm. Details at www.P65Warnings.ca.gov.
