Pietra Gray Marble12 × 24 Polished

A dark gray marble tile with fine white veining, in a 12 × 24 format with a polished finish.

Pietra Gray runs from deep charcoal to slate gray, threaded with fine white and ivory veins. Some lines are hairline thin. Others are bolder and run the length of the tile. The polished finish deepens the dark field and sharpens the contrast with the veining.

The 12 × 24 rectangle lays straight or in an offset brick pattern. Fewer grout lines give a wall or low-traffic floor a calm, continuous look. Polished stone shows water spots and fingerprints, so it suits rooms that are easy to wipe down.

Samples are $7.99 each, up to 10 per order. Samples ship free. 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

  • Feature WallA polished dark field with pale veining gives a living room or bedroom wall real presence.
  • Bathroom WallLarge tiles keep grout lines few on vanity walls and tub surrounds. Seal the stone first.
  • Kitchen BacksplashA dark, veined backdrop behind the range or counter. Wipe up splashes promptly.
  • Low-Traffic FloorSuits a dry indoor floor such as an entry or powder room, where scratches are less likely.
  • Outdoor & Frost-Exposed AreasThis polished marble is made for indoor use. Choose a material rated for exteriors.
  • Commercial or High-Traffic FloorsPolished dark stone shows scratches over time. A honed finish wears better under heavy use.

Care & Cleaning

Seal It

Apply a penetrating stone sealer before grouting and again after installation. In wet areas, re-seal every 12 months to guard against moisture and staining.

Clean It

Use a pH-neutral stone cleaner or diluted mild dish soap in warm water. Skip vinegar, citrus, bleach and abrasive scrubbers.

Expect This

Polished marble can etch from acids and shows water spots and fingerprints more than honed stone. Dry the surface after wet use. Veining and tone 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 order 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.

How do I order a sample?

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

Does Pietra Gray need to be sealed?

Sealing protects the stone from moisture and stains. Use a penetrating stone sealer before grouting and again after installation. In wet areas, re-seal every 12 months.

How do I clean polished Pietra Gray?

A pH-neutral stone cleaner or mild dish soap in warm water works well. Wipe spills promptly and dry the surface, since acids such as vinegar and citrus can etch the polish.

Can I use it outdoors?

Pietra Gray 12 × 24 polished is made for indoor floors and walls. The polished finish is not suited to exterior or frost-exposed areas.




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.
  • Larger or custom quantity? Contact us for a tailored quote.

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.
