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.

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.
