About Thassos White Marble Octave with Black Dots Honed Mosaic

Material Education

Thassos marble is a pure white crystalline stone quarried from the Greek island of Thassos, renowned for producing one of the whitest marbles on earth. Its luminous, sugar-crystal surface is virtually free of veining, delivering an almost glowing brightness that few other natural stones can match. The honed finish softens the reflectivity to a silky matte sheen, enhancing the tactile quality of the stone while preserving its signature brilliance.

As a product of nature, individual tiles may display subtle shifts in crystalline grain and tone — slight warm or cool undertones are a hallmark of genuine Thassos marble and are considered part of its natural beauty.

About this mosaic: This mosaic features large Thassos white octagon pieces paired with small black marble dot inserts, all pre-arranged and factory-mounted on a mesh-backed sheet for fast, consistent installation. The octagon-and-dot layout is a classic geometric format that arrives ready to set, dramatically reducing layout time on the job site.

Design & Inspiration

The crisp, pure white field of Thassos pairs beautifully with matte black fixtures, polished chrome hardware, warm brass accents, and deep charcoal grout — suiting everything from classic Victorian bathrooms to minimalist contemporary spa retreats. Its cool, bright palette also complements white oak cabinetry, Carrara marble countertops, and soft linen tones for a light-filled transitional aesthetic.

The octagon-and-dot format is a timeless pattern that creates a graphic, structured rhythm without overwhelming a space — ideal for bathroom floors, shower floors, and powder room feature walls where a classic yet refined statement is desired. The high-contrast black dot inserts act as natural visual punctuation, adding depth and preventing the all-white surface from feeling flat.

Popular design combinations: pair with Thassos white subway tiles on the walls, matte black fixtures, and warm brass towel hardware for a boutique hotel bathroom look. Explore the full Thassos White collection for coordinating sizes, and browse more marble mosaics for complementary looks.

Thassos White marble is quarried on the Greek island of Thassos and is celebrated worldwide as one of the purest, brightest white marbles available. Its dense crystalline structure gives it an almost luminous, backlit quality that instantly elevates any interior.

This mosaic is honed to a smooth, satin-matte finish and arranged in a classic octagon-and-dot pattern, with large white Thassos octagons accented by small black marble dot inserts. Mounted on a mesh backing, each sheet installs quickly and maintains perfectly consistent spacing, making it an excellent choice for both professional tile setters and skilled DIYers.

Best suited for bathroom floors, shower floors, and powder room walls, this mosaic is a timeless choice that works in traditional, transitional, and modern interiors alike. Because this is a natural stone clearance item, we recommend ordering a sample before committing to a full quantity, and purchasing 10–15% overage to account for cuts and pattern matching.

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 marble is a bright white, dense stone but remains porous and must be sealed before installation. Apply a premium penetrating stone sealer prior to grouting and reseal every 12 months in shower and wet-area applications. A colour-enhancing or neutral impregnating sealer is recommended to preserve the stone's natural white appearance without yellowing.

Cleaning: Clean with a pH-neutral stone cleaner and a soft microfiber cloth or mop. Avoid vinegar, citrus-based cleaners, bleach, or any acidic or alkaline products, as these will etch the honed surface and permanently dull the finish. Wipe up spills promptly — particularly oils, coffee, and dark liquids — as the bright white surface can show staining more readily than darker stones.

Installation: Use white polymer-modified thinset mortar to prevent any grey bleed-through on the translucent white Thassos chips. Align mesh-backed sheets carefully, butting edges together before pressing firmly into the mortar. Use non-sanded grout for joints under 1/8 inch. Back-butter individual sheets in addition to spreading thinset on the substrate to ensure full coverage and prevent hollow spots. Allow full cure before grouting.

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.
