Bianco Dolomite Marble18 × 18 Polished

A bright white marble with grey veining, in an 18 × 18 format with a reflective polish.

Bianco Dolomite is a white marble with a clean, bright ground and grey veining that runs in soft, directional lines. The polished finish reflects light and gives the surface a glossy depth.

At 18 × 18, each tile shows a generous stretch of the stone's pattern, with fewer grout joints than a small-format tile. Variation is moderate (V3), so expect vein intensity and direction to differ from tile to tile. It is intended for indoor floors and walls.

Samples are $7.99 each, up to 10 per order. Samples ship free, within 1-3 business days. Your sample comes from the lot we have in stock now, so it shows that lot's actual color range and finish. Future lots may look lighter, darker, or more veined, so order your full quantity plus 10% at once to keep the whole job from one lot.

Where It Works

Bathroom wallsThe polished surface reflects light and suits a bright, clean bath.
Feature wallThe veining reads best across a full wall with little interruption.
Entryway floorAn indoor, low-traffic floor where the 18 × 18 format shows the stone's pattern.
Kitchen backsplashA bright, polished backdrop. Seal it and wipe up acidic spills promptly.
Wet outdoor areasPolished marble is slippery when wet outdoors. It is an indoor tile.
High-traffic commercial floorsA polished surface can scratch and etch over time under heavy use.

Care & Cleaning

Seal It

Marble is porous. Apply a penetrating stone sealer before grouting and reapply regularly. In wet areas, every 6–12 months is a sensible interval.

Clean It

Use a pH-neutral stone cleaner and a soft cloth. Skip vinegar, lemon, bleach and other acidic or alkaline cleaners, which can dull the polish.

Expect This

Polished marble can etch from acids such as wine, coffee and citrus, so wipe spills quickly. Veining will vary from tile to tile.

Tile & Mosaic Depot supplies material only. Installation method, setting materials, and substrate are your installer's responsibility. Inspect every piece before setting; installation is acceptance, and installed material cannot be returned or claimed.

Questions

Will my tile match the sample?

Your sample comes from the lot we have in stock now, so it shows that lot's actual color range and finish. Future lots may look lighter, darker, or more veined, so order your full quantity plus 10% at once to keep the whole job from one lot.

Can I use this tile on a floor?

Yes, it is intended for indoor floors and walls, including entryways and bathroom walls. Polished marble is best kept to dry, lower-traffic floors. If you are considering a shower floor, ask us first, as that use is not specified for this tile.

Does Bianco Dolomite need to be sealed?

Sealing protects the white ground from moisture and stains. Apply a penetrating stone sealer before grouting and reapply regularly, more often in wet areas.

How much should I order?

Each 18 × 18 tile covers 2.25 sq ft, and this tile is sold per sq ft. Add 10% to your measured area for cuts and waste, and order it all at once so it comes from one lot.

How do I order a sample?

Add up to 10 samples to one order at $7.99 each. Samples ship free, and they go out within 1-3 business days.

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.

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.
