Charcoal Grey Limestone is a refined sedimentary stone celebrated for its deep, cool grey tones, subtle fossil detail, and understated natural veining. Quarried in Europe, it brings a timeless, architectural gravitas to both residential and commercial interiors.

Finished with a leathered surface treatment, this 18×18 tile offers a velvety, low-sheen texture that softens reflections while enhancing the stone's natural relief. The large format minimizes grout joints for a sleek, continuous look, and the leathered finish helps conceal minor scratches and water spots better than a polished alternative.

Best suited for interior floors, feature walls, and covered outdoor applications, this tile is an excellent choice for entryways, bathrooms, kitchens, and living areas seeking a bold, sophisticated foundation. As a clearance or specialty stone, ordering a sample is strongly recommended to confirm color and texture match prior to purchase.

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: Limestone is a porous stone and must be sealed before installation and regularly maintained. Apply a penetrating stone sealer prior to grouting and reseal every 12–18 months in wet areas such as bathrooms and kitchens. The leathered finish is slightly more resistant to staining than polished but sealing remains essential.

Cleaning: Clean with a pH-neutral stone cleaner diluted in warm water and a soft mop or cloth. Avoid acidic cleaners, vinegar, citrus-based products, and bleach, all of which will etch and dull the limestone surface over time. Wipe up spills promptly, especially acidic liquids like wine, coffee, and juice.

Installation: Use a white or grey polymer-modified thinset mortar appropriate for large-format stone tiles. Back-butter each tile in addition to applying thinset to the substrate to ensure full coverage and prevent hollow spots. Use tile leveling clips to maintain consistent plane across the 18×18 format. Allow for proper expansion joints at perimeter walls and transitions.

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.

Order a Sample First

Seeing real stone in your own space — under your own light, beside your own finishes — is the best way to buy with confidence. We make it easy and affordable.

How It Works
Samples are just $7.99 each with free shipping, and they ship in 1–3 business days. Sizes vary by material and availability, typically ranging from 3"×3" up to 8"×8". Exact dimensions aren't guaranteed, but every sample is cut from the same material you'll receive in a full order.

What a Sample Shows
Samples help you evaluate the general color, texture, finish, and overall character of a product before committing to a full order. Because natural stone varies from piece to piece, your sample is representative — it may not capture the complete range of variation across an entire lot. For current lot photos, just ask our team.

Good to Know

  • Samples are final sale — non-returnable and non-refundable.
  • Ordering a sample before a full purchase is always recommended, especially for natural stone.
  • Planning a larger or custom quantity? Contact us for a tailored quote.
