About Bianco Dolomite Marble 18×18 Honed Tile

Material Education

Bianco Dolomite is a natural marble quarried in Turkey, prized for its crisp white to soft gray base punctuated by charcoal and warm taupe veining. Its crystalline grain structure gives the surface a subtle sparkle even under a honed finish, lending understated elegance to any space. The tonal contrast between the bright field and bold veining makes each slab — and every tile cut from it — visually dynamic.

As a product of nature, no two tiles are identical; slight shifts in vein density, color tone, and mineral patterning are the hallmark of genuine Bianco Dolomite marble and should be embraced as part of its character.

About this tile: This 18×18 honed tile is a large-format field tile cut to a square format that lays up quickly on floors and walls, minimizing grout lines for a clean, expansive look. The matte honed surface diffuses light softly, making it ideal for spaces where a polished sheen would be too formal.

Design & Inspiration

Bianco Dolomite's white-gray palette pairs beautifully with warm brass fixtures, matte black hardware, white oak cabinetry, and soft greige wall colors, suiting modern, transitional, and classic interiors alike. Its bold veining adds movement without overwhelming a room, making it equally at home in a minimalist spa bathroom or a traditional kitchen.

The generous 18×18 square format creates a seamless, gallery-like floor plane that visually expands smaller rooms and anchors open-plan spaces. The honed finish softens the contrast between field and vein, resulting in a sophisticated, muted elegance rather than high-gloss drama.

Popular design combinations: pair Bianco Dolomite honed floor tiles with a polished Calacatta Gold marble feature wall and satin brass fixtures for a layered, luxurious master bath. Explore the full Marble collection for coordinating sizes, and browse more Marble tile for complementary looks.

Bianco Dolomite is a striking natural marble sourced from quarries in Turkey, featuring a bright white to cool gray base laced with bold charcoal and warm taupe veining. Its crystalline structure gives the stone a quiet luminosity that elevates both contemporary and classic interiors.

Cut to a generous 18×18 inch square and finished with a smooth honed surface, this tile delivers a refined matte look that resists the fingerprints and water-spot visibility associated with polished marble. The large format minimizes grout joints, creating a fluid, uninterrupted surface ideal for open, expansive layouts.

Bianco Dolomite honed tile is well suited to master bath floors, shower walls, kitchen floors, and feature walls in living areas. Because this is a clearance or natural-stone product with inherent variation, ordering a sample before purchasing your full quantity is strongly recommended to confirm the tone and veining density suit your project.

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 marble should be sealed with a penetrating stone sealer before grouting and immediately upon installation. In wet areas such as showers and bathroom floors, reseal every 6–12 months to protect against moisture penetration and staining. The white base tone makes this stone particularly susceptible to discoloration from oils, wine, and acidic liquids, so consistent sealing is strongly advised.

Cleaning: Clean with a pH-neutral stone cleaner and a soft microfiber cloth or mop. Avoid vinegar, citrus-based cleaners, bleach, or any acidic or alkaline products, which will etch the honed surface and dull its finish. Although honed marble is slightly more forgiving than polished marble regarding visible etching, prompt cleanup of spills — especially oils, coffee, and red wine — is essential.

Installation: Use white polymer-modified thinset mortar to prevent gray thinset from telegraphing through the lighter stone. Back-butter each tile in addition to applying thinset to the substrate to ensure full coverage and eliminate voids beneath the large-format slab. Use a 3/16" to 1/4" notched trowel and maintain consistent 1/16"–1/8" grout joints; unsanded grout is acceptable at narrow joints, while sanded grout suits wider joints. Allow thinset to fully cure before grouting.

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.
