About Thassos White Marble 12×24 Honed Tile

Material Education

Thassos White is an exceptionally pure white marble quarried exclusively from the island of Thassos in the Aegean Sea, renowned worldwide for its brilliant, snow-white surface and fine crystalline grain. Unlike most white marbles, Thassos contains virtually no veining, producing a luminous, cloud-free field of white that reflects light with a distinctive, almost glowing quality. Its dense crystalline structure gives it a subtle sparkle that sets it apart from other white stones.

As a genuine natural stone, minor variations in crystal size and occasional faint translucency are inherent characteristics of authentic Thassos marble — these subtle nuances are a mark of its natural origin and add depth to an otherwise pristine surface.

About this tile: This 12×24 honed tile features Thassos White marble in a large-format rectangle with a smooth, matte finish that tempers the stone's natural brilliance into a softer, velvety appearance — ideal for creating expansive, seamless surfaces on floors and walls.

Design & Inspiration

Thassos White's pure, unblemished white palette pairs beautifully with polished chrome, brushed nickel, warm brass fixtures, and crisp white oak or walnut cabinetry, anchoring both minimalist modern and serene spa-inspired interiors. Its neutral perfection also complements bold accents such as Nero Marquina black marble, navy cabinetry, or aged bronze hardware for striking contrast.

The 12×24 large-format rectangle creates long, uninterrupted sight lines that visually expand a space, making it a favorite choice for master bathroom floors, shower surrounds, and feature walls where a seamless, gallery-like surface is desired. Laid in a staggered brick pattern or straight stack, this format emphasizes the stone's pure white expanse and minimizes grout interruption.

Popular design combinations: pair with a Thassos White 1×2 herringbone mosaic accent band and polished chrome fixtures for a cohesive, luxury spa bathroom. Explore the full Thassos White Collection for coordinating sizes, and browse more Marble Tile for complementary looks.

Thassos White marble originates exclusively from the Greek island of Thassos and is celebrated as one of the world's purest white marbles — a dense, crystalline stone with virtually no veining and a naturally luminous, snow-white surface.

Finished with a precision hone, this 12×24 tile offers a smooth, low-sheen surface that softens the stone's natural brilliance while retaining its refined elegance; the large-format size speeds installation and dramatically reduces grout lines for a clean, continuous look.

Best suited for bathroom floors, shower walls, and feature walls in dry or properly waterproofed wet areas; because Thassos is a dense but pale stone highly susceptible to staining, sealing before and after grouting is strongly recommended — ordering a sample first is advised to appreciate the tile's true white tone in your lighting conditions.

Free Shipping: This product ships at standard freight rates calculated at checkout based on your location and order size.

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 pale, porous marble that must be sealed before installation and again after grouting with a high-quality penetrating stone sealer. In wet areas such as showers, re-seal every 6–12 months to prevent staining and moisture infiltration. Because of its pure white surface, even minor staining is highly visible, making diligent sealing especially critical.

Cleaning: Clean with a pH-neutral stone cleaner or mild dish soap diluted in warm water — never use acidic cleaners (vinegar, citrus), bleach, or abrasive scrubbers, which will etch and dull the honed surface. Wipe up spills immediately, particularly oils, coffee, or colored liquids, as the white stone will absorb stains quickly. Dry the surface after cleaning in wet areas to prevent water spotting.

Installation: Always use white polymer-modified thinset mortar to prevent any gray bleed-through on this ultra-white stone. Back-butter each tile in addition to combing the substrate to ensure full coverage and prevent lippage on the large-format tiles. Use a non-staining white grout and seal all grout joints thoroughly before use; a 1/16"–1/8" grout joint is recommended for a tight, near-seamless appearance.

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.

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
