Fossil Brown Limestone

Fossil Brown limestone — warm brown natural limestone with fossil character in leathered and polished tiles. An earthy stone for floors and walls.

About Fossil Brown Limestone 18×18 Leathered Tile

Material Education

Fossil Brown is a richly textured limestone quarried in the Atlas Mountain region of North Africa, celebrated for its warm chocolate-brown and caramel tones interspersed with naturally occurring fossilized marine organisms. The stone presents an earthy, organic palette accented by ivory and taupe fossil impressions that create an almost archaeological visual narrative across every tile. Its dense composition and subtle crystalline matrix give it a grounded, tactile character that stands apart from more uniform sedimentary stones.

Because Fossil Brown is a product of ancient marine sediment, each tile carries a unique arrangement of fossils, color shifts, and tonal depth — this natural variation is the hallmark of authentic limestone and is considered a desirable feature, not a flaw.

About this tile: This 18×18 field tile is finished with a leathered surface, a mechanical process that lightly textures the face of the stone to produce a soft matte sheen with gentle peaks and valleys — making it notably slip-resistant while preserving and enhancing the stone's inherent fossil detail.

Design & Inspiration

Fossil Brown's warm brown, taupe, and ivory palette pairs beautifully with brushed brass or oil-rubbed bronze fixtures, white oak cabinetry, linen upholstery, and warm-toned grouts, suiting earthy contemporary, Mediterranean, transitional, and biophilic interior styles. Its naturally muted, organic tones anchor a space without competing with other design elements.

The generous 18×18 format lays up efficiently to create expansive, visually calming floors with minimal grout lines, while the leathered finish adds dimension and a sophisticated tactile quality that polished stone simply cannot replicate. This size and finish combination is especially powerful in open-plan living areas, spa bathrooms, and covered outdoor patios where large-scale natural texture is desired.

Popular design combinations: Fossil Brown leathered floors paired with warm white plaster walls, brushed brass faucets, and a teak vanity for a luxurious earthy spa bathroom. Explore the full Limestone collection for coordinating sizes, and browse more natural stone tile for complementary looks.

Fossil Brown Limestone is a striking natural stone sourced from the Atlas Mountain region of North Africa, distinguished by its warm chocolate-brown and caramel base tones punctuated by an abundance of fossilized marine shell and coral impressions in ivory and taupe. Each 18×18 tile is a one-of-a-kind record of prehistoric ocean life, making this material as visually compelling up close as it is at room scale.

The leathered finish is applied through a diamond-brushing process that gently roughens the tile surface, creating a low-sheen, matte appearance with subtle texture that accentuates every fossil and tonal variation within the stone. This finish is notably more forgiving than polished limestone — it conceals water spots, light scratches, and everyday smudging while providing improved traction underfoot, making it an excellent choice for high-use floor applications.

Fossil Brown leathered tile is ideal for interior floors, feature walls, bathroom floors, and covered outdoor spaces such as patios or loggia — the leathered finish performs exceptionally well in areas where durability and slip resistance matter. As a clearance or natural stone product with inherent shade variation, ordering a sample before committing to a full installation is strongly recommended to confirm the color matches your project vision.

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: Fossil Brown Limestone must be sealed with a high-quality penetrating stone sealer prior to installation and grouting. Reseal annually in bathroom floors and wet areas, and every two years in lower-traffic areas. The leathered finish is more porous than polished limestone and will readily absorb oils and liquids if left unsealed.

Cleaning: Clean with a pH-neutral stone cleaner diluted in warm water — never use vinegar, lemon-based cleaners, bleach, or any acidic or alkaline products, as limestone is highly susceptible to etching and surface degradation from acids. For the leathered finish, avoid abrasive scrub pads; a soft microfiber mop or cloth is sufficient for routine cleaning. Wipe up spills, especially acidic liquids like wine or citrus juice, immediately.

Installation: Install with a large-format gray or beige polymer-modified thinset mortar; back-butter each tile in addition to combing the substrate to ensure full coverage and eliminate hollow spots in the 18×18 format. Use a grout joint of at least 3/16 inch to accommodate natural stone calibration tolerances. Select a sanded grout in a warm beige or mocha tone to complement the stone's earthy palette. Ensure the substrate is flat to within 1/8 inch over 10 feet before tiling.

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.

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
