About Tundra Gray Marble Honed Tile

Material Education

Tundra Gray is a natural marble quarried in the Mediterranean region, prized for its cool blue-gray base punctuated by soft white veining and occasional warm beige undertones. Its finely grained crystalline structure gives the stone a refined, sophisticated character that reads as both calming and architecturally bold. The honed finish reveals the stone's subtle tonal depth without the high reflectivity of a polished surface.

As a genuine natural stone, Tundra Gray will exhibit slight variations in vein intensity, background tone, and mineral patterning from tile to tile — these organic differences are the hallmark of authentic marble and contribute to the material's timeless visual richness.

About this tile: This 18×18 honed tile offers a generous format ideal for floor installations and large wall applications, allowing the natural veining to flow across broad surfaces with minimal interruption. The matte honed finish provides a smooth, non-reflective surface that is both elegant and practical for high-use areas.

Design & Inspiration

Tundra Gray's cool gray palette pairs beautifully with brushed nickel and matte black fixtures, white oak cabinetry, and crisp white grout for a clean modern aesthetic, or with warm brass hardware and walnut tones for a transitional spa-inspired look. It suits a wide range of interior styles including contemporary minimalism, Scandinavian design, coastal transitional, and understated classic interiors.

The 18×18 format is particularly effective in open-plan living areas, master bathrooms, and foyer floors, where its expansive field reduces grout lines and lets the stone's natural veining take center stage. The honed finish also lends itself well to shower floors and walls where a matte surface adds both visual warmth and a degree of slip resistance compared to polished marble.

Popular design combinations: Tundra Gray 18×18 honed floors paired with Thassos White marble mosaic shower walls and polished chrome fixtures for a light, airy spa retreat. Explore the full Marble Tile Collection for coordinating sizes, and browse more Marble Tile for complementary looks.

Tundra Gray is a natural marble celebrated for its cool blue-gray ground, delicate white veining, and subtle warm undertones that give it a sophisticated, versatile character. Quarried in the Mediterranean region, it has long been a favorite in high-end residential and hospitality design for its ability to bridge classic and contemporary aesthetics.

Finished with a smooth honed surface, this 18×18 tile delivers a matte, non-reflective look that feels grounded and refined — ideal for spaces where understated luxury is the goal. The larger format minimizes visible grout joints across floors and walls, creating a seamless, gallery-like expanse that highlights the stone's natural movement and veining.

Tundra Gray 18×18 honed tile is well suited for bathroom floors, shower surrounds, foyer entries, kitchen floors, and feature walls in living spaces. Because this product may be offered as a clearance or limited-quantity item, ordering a sample to verify color match in your space is strongly recommended before purchasing full quantities.

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: Tundra Gray marble should be sealed with a penetrating stone sealer before installation and re-sealed every 12 months in dry areas or every 6 months in wet areas such as showers and bathroom floors. As a gray marble with a honed finish, it is moderately absorbent and sealing is essential to prevent staining from oils, soaps, and minerals.

Cleaning: Clean with a pH-neutral stone cleaner or mild dish soap diluted in water; rinse thoroughly and dry with a soft cloth to prevent water spotting. Avoid acidic cleaners, vinegar, citrus-based products, and abrasive scrubbers — these will etch and dull the honed surface over time. The honed finish, while less prone to visible scratching than polished marble, will show etching if exposed to acids.

Installation: Use a white polymer-modified thinset mortar to prevent any gray bleed-through on the stone face, especially near lighter veined areas. Back-butter each 18×18 tile in addition to troweling the substrate to ensure full coverage and eliminate hollow spots. Use tile spacers consistent with your desired grout joint width and a non-sanded or fine-sanded grout for joints under 1/8 inch; for wider joints use sanded grout matched to the stone's cool gray tones.

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
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.
