About Thassos White Marble Octave with Blue Dots Honed Mosaic

Material Education

Thassos marble is a pure white crystalline stone quarried exclusively from the Greek island of Thassos, renowned for producing some of the whitest marble in the world. Its exceptionally bright, sugary-white surface is composed of large interlocking calcite crystals that reflect light with an almost luminous glow, setting it apart from ivory-toned or veined white marbles. The honed finish on these tiles softens the crystalline sparkle to a silky, matte-smooth surface that feels refined and sophisticated.

As a natural stone, each chip of Thassos may show subtle shifts in crystal grain size or faint translucency — these are the hallmarks of genuine quarried marble, not imperfections, and contribute to the tile's organic depth and authenticity.

About this mosaic: Octagon chips are paired with contrasting blue dot inserts and pre-arranged on a mesh-backed sheet, delivering the classic octagon-and-dot pattern in a format that installs quickly and accurately without the need to individually set each piece.

Design & Inspiration

The brilliant snow-white field tiles paired with richly pigmented blue dot accents create a crisp, jewel-like contrast that suits contemporary, coastal, art-deco-inspired, and timeless classic interiors equally well. Thassos' icy white tone pairs beautifully with polished chrome or brushed nickel fixtures, white oak cabinetry, navy or soft grey grout, and Carrara marble trim pieces.

The octagon-and-dot format is a perennial favorite for bathroom floors, where the geometric grid anchors the space with visual structure while the blue dots introduce a playful focal point without overwhelming the room. As a shower wall mosaic or powder room accent, the honed surface provides a soft, spa-like quality that polished stone cannot replicate.

Popular design combinations: pair with Thassos White 12×24 honed field tiles on walls, Carrara marble pencil liner trim, and polished chrome fixtures for a fresh, timeless bathroom.

Thassos White is the world's purest white quarried marble, sourced exclusively from the Greek island of Thassos and prized by designers for its brilliant, crystalline-white surface that outshines virtually any other white stone. This mosaic presents the iconic octagon-and-dot layout, with bright white Thassos octagons set against small blue marble dot inserts for a striking geometric contrast.

Each tile arrives honed to a silky-smooth, low-sheen finish that gives the surface a refined, understated elegance ideal for spa-inspired spaces. The chips are factory-arranged on a mesh backing, allowing for fast, consistent installation and perfectly aligned grout joints — a significant advantage in intricate patterns like octagons.

This mosaic is ideally suited for bathroom floors, shower floors, and powder room feature walls, and its timeless pattern works equally well in traditional and modern settings. Because this is a clearance or specialty item, ordering a sample first is strongly recommended to verify the blue dot tone against your fixtures and cabinetry before committing to a full order.

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, bright marble and one of the most porous white stones available — sealing before grouting and immediately after installation is essential. Apply a high-quality penetrating stone sealer and re-seal every 6–12 months in wet areas such as shower floors and bathroom floors to prevent moisture absorption, staining, and discoloration of the blue dot inserts.

Cleaning: Clean with a pH-neutral stone cleaner and a soft mop or cloth only — never use acidic cleaners (vinegar, citrus), bleach, or abrasive scrubbers, as acid will etch the honed marble surface and dull its finish permanently. Wipe up spills — especially colored liquids, coffee, or oils — immediately, as Thassos' bright white surface will highlight any staining. Avoid steam mops on natural stone.

Installation: Use white polymer-modified thinset mortar to prevent any gray adhesive from telegraphing through the translucent white Thassos chips. Install sheets mesh-side down, pressing evenly across the entire sheet to ensure full adhesive contact. Use non-sanded grout for joints under 1/8 inch; for the blue dot joints, verify grout color against the blue inserts before committing to a full bag. Back-butter individual chips as needed on shower floors to achieve 95%+ adhesive coverage.

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.
