About Bianco Dolomite Marble Polished Tile

Material Education

Bianco Dolomite is a striking white marble quarried in Turkey, prized for its bright white base and bold, dramatic grey veining that cuts across the surface with energy and movement. The polished finish amplifies the stone's natural crystalline structure, producing a reflective, mirror-like sheen that makes its high-contrast veining truly pop. Its luminous surface and graphic patterning place it among the most visually arresting white marbles available.

As a product of nature, each tile of Bianco Dolomite will vary in the intensity, direction, and density of its grey veining — this natural variation is the hallmark of genuine stone and ensures every installation is one of a kind.

About this tile: This 18×18 polished field tile offers a generous, floor-friendly format that showcases the full sweep of Bianco Dolomite's dramatic veining across each slab-sized piece. The larger format minimizes grout joints for a cleaner, more seamless look and installs efficiently on both floors and walls.

Design & Inspiration

Bianco Dolomite's crisp white ground and bold charcoal-grey veining pairs beautifully with polished chrome, matte black fixtures, white oak cabinetry, and dark grout lines, fitting naturally into modern, transitional, and classic interior styles. Its high contrast makes it equally at home in dramatic contemporary bathrooms as it is in timeless kitchen and foyer designs.

The 18×18 format is ideal for open bathroom floors, entryways, and feature walls where the full scale of the veining can be appreciated without interruption — the polished finish reflects light and visually enlarges the space. Laid in a straight-set grid with thin matching or contrasting grout, it creates a refined, gallery-like atmosphere.

Popular design combinations: Bianco Dolomite 18×18 polished floors paired with matte black vanity hardware, white shaker cabinetry, and a Bianco Dolomite subway tile accent wall for a cohesive, high-end bath suite.

Premium Natural Stone

Secure Packaging

Bianco Dolomite is a natural white marble sourced from quarries in Turkey, defined by its vivid bright white background and bold, sweeping grey veining that gives each tile a dynamic, painterly quality. The polished surface finish intensifies the stone's inherent brilliance, delivering a glossy, light-reflective sheen that enhances both the contrast and depth of its veining.

Cut to an 18×18 inch format and polished to a high gloss, these field tiles are designed to minimize grout joints and maximize the visual continuity of the stone's dramatic patterning. The result is an expansive, seamless aesthetic that makes spaces feel larger, more open, and unmistakably luxurious.

This tile is well-suited for bathroom floors, foyer installations, feature walls, and shower surrounds where a bold yet refined statement is desired. As a clearance or natural-stock item, ordering a sample first is strongly recommended to confirm shade and veining match your project expectations before committing to a full quantity.

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 grouting and regularly thereafter — apply a penetrating stone sealer every 6–12 months in wet areas such as showers and bathroom floors to guard against moisture, staining, and discoloration. The white ground is particularly susceptible to staining from colored liquids, oils, and soap residue, so diligent sealing is strongly recommended.

Cleaning: Clean with a pH-neutral stone cleaner and a soft microfiber cloth; never use vinegar, lemon juice, bleach, or any acidic or alkaline cleaners, as these will etch and permanently dull the polished surface. Wipe up spills — especially wine, coffee, and citrus — immediately, as the polished finish, while beautiful, is more vulnerable to acid etching than honed or tumbled finishes.

Installation: Use white polymer-modified thinset mortar to prevent any grey adhesive from telegraphing through the stone on this pale marble. Back-butter each tile in addition to applying thinset to the substrate for full, void-free coverage on the 18×18 format. Use a 3/16" to 1/4" grout joint and a non-sanded or fine-sanded grout in a complementary tone; ensure the substrate is flat and rigid to prevent cracking of this natural stone.

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.
