About Bianco Dolomite Marble 4×12 Polished Tile

Material Education

Bianco Dolomite is a white dolomitic marble quarried in Turkey, prized for its crisp white base and bold, sweeping grey veins that cut dramatically across the surface. Its high dolomite mineral content gives it a slightly warmer, denser character than classic Carrara, with a luminous polished face that amplifies every vein and crystal within the stone. The result is a striking, high-contrast natural stone that feels both fresh and timeless.

As with all natural marble, no two tiles are identical — variation in veining density, direction, and shade intensity is an inherent signature of genuine Bianco Dolomite and contributes to its authentic, one-of-a-kind character.

About this tile: This 4×12 field tile format — often called a 'subway plank' — offers a modern elongated profile that emphasizes horizontal or vertical lines in any layout. Each tile arrives individually cut and polished, ready for straight-set or stacked installation on walls and select floor applications.

Design & Inspiration

Bianco Dolomite's white-and-grey palette pairs beautifully with brushed brass or matte black fixtures, warm white oak cabinetry, and cool concrete or grout tones, suiting contemporary, transitional, and minimalist spa-inspired interiors alike. Its bold veining provides enough visual energy to anchor a feature wall without the need for additional pattern or ornamentation.

The 4×12 elongated format creates a sense of height when installed vertically and a calm, expansive feel when laid in a horizontal brick pattern, making it ideal for shower surrounds, vanity walls, and kitchen backsplashes where a refined yet dramatic stone look is desired. The polished finish reflects light generously, brightening smaller spaces and enhancing the natural depth of the veining.

Popular design combinations: pair vertically stacked Bianco Dolomite 4×12 tiles with a Bianco Dolomite hexagon mosaic floor and polished chrome fixtures for a cohesive, gallery-style bathroom.

Bianco Dolomite is a striking white dolomitic marble sourced from quarries in Turkey, distinguished by its bright white field and bold, sweeping charcoal-grey veins that give it a more dramatic character than many classic white marbles. This 4×12 polished tile captures the full luminosity and pattern of the stone in a sleek, elongated format.

The high-gloss polished finish heightens the contrast between the white base and dark veining while producing a reflective surface that adds depth and light to any room. The versatile subway-plank proportion works equally well in horizontal brick-set, vertical stacked, or offset patterns, giving designers and homeowners significant creative flexibility.

Bianco Dolomite 4×12 tiles are well suited to bathroom walls, shower surrounds, kitchen backsplashes, and accent applications in living areas. Because polished marble is more susceptible to etching from acids, we recommend sealing before use and ordering a sample to confirm color and vein variation in your specific 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: Bianco Dolomite is a porous white marble that should be sealed before installation and resealed every 6–12 months in wet areas such as showers and around sinks. Use a premium penetrating (impregnating) stone sealer formulated for marble to protect against moisture, staining, and mineral deposits. Lighter stones show staining more readily, so diligent sealing is especially important.

Cleaning: Clean with a pH-neutral stone cleaner and a soft cloth or mop — never use vinegar, citrus-based cleaners, bleach, or abrasive scrubbers, as acids will etch the polished surface and leave dull spots. Wipe up spills immediately, particularly coffee, wine, juice, and oils, to prevent staining. For daily maintenance, warm water and a microfiber cloth are sufficient.

Installation: Use white polymer-modified thinset mortar to prevent any grey adhesive from telegraphing through the semi-translucent white marble. A 3/16" V-notch or 1/4" square-notch trowel is appropriate for this format; back-butter each tile for full coverage on walls. Install with a 1/16" joint and finish with a non-sanded white or light grey grout. Dry-lay tiles before installation to distribute veining variation naturally across 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.

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.
