About White Carrara Marble Polished Quarter Round Trim

Material Education

White Carrara marble is quarried from the Apuan Alps of Tuscany, one of the world's most storied stone-producing regions. It is characterized by a soft white to light grey background laced with feathery grey veining and a subtle crystalline luminosity that catches light elegantly. Its warm, creamy undertones distinguish it from brighter white marbles, lending spaces a timeless and refined character.

As a product of nature, each piece of Carrara marble will display its own unique veining density and tone — slight differences from piece to piece are the hallmark of genuine natural stone and add authentic warmth to any installation.

About this molding: This 1×12 quarter round molding features a gracefully curved profile milled from solid Carrara marble and finished to a high polish, creating a smooth, reflective transition between two surfaces. Sold per linear foot, it is designed to cap edges, finish baseboard transitions, and provide elegant detail work wherever a polished stone border is needed.

Design & Inspiration

The soft white and grey palette of this quarter round pairs beautifully with chrome and brushed nickel fixtures, white oak cabinetry, and cool-toned field tiles in materials like Thassos white, Calacatta, or subway ceramic. It suits a broad range of styles, from classic European bathrooms to clean, modern spa retreats and transitional kitchen designs.

The 1×12 quarter round format is ideal for finishing shower floor-to-wall transitions, framing wainscoting, and capping backsplash edges with a cohesive, built-in look. The polished finish reflects light along the curve of the molding, adding a jewel-like detail that elevates even simple tile layouts.

Popular design combinations: pair with White Carrara 3×6 polished subway tile and a Carrara marble hex floor for a fully coordinated, hotel-inspired bathroom. Explore the full White Carrara Marble collection for coordinating sizes, and browse more marble moldings & trims for complementary looks.

The White Carrara Marble 1×12 Polished Quarter Round Trim is crafted from solid natural Carrara marble, sourced from the legendary quarries of Tuscany. Its soft white base and characteristic grey feather veining bring classic Italian elegance to any tiling project.

Milled to a precise quarter-round profile and polished to a mirror-like sheen, this molding creates a smooth, decorative transition between floor and wall surfaces, or along any exposed tile edge. The high-polish finish enhances the natural veining and adds a refined, luminous detail that coordinates seamlessly with other Carrara marble field tiles and mosaics.

This trim piece is ideally suited for shower enclosures, bathroom wainscoting edges, kitchen backsplash borders, and fireplace surrounds. As a clearance or accent trim item, ordering a sample is recommended to confirm vein tone and finish match with existing or planned field tiles before committing to a full order.

Free Shipping: As a molding, this product qualifies for free curbside shipping on orders over $1,999 within the continental U.S. Orders below that threshold ship at standard rates calculated at checkout.

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: Seal this Carrara marble molding with a penetrating stone sealer before installation and re-seal every 6–12 months in wet areas such as showers. As a pale white stone, Carrara is more susceptible to staining and should be sealed thoroughly and regularly to protect against moisture and product absorption.

Cleaning: Clean with a pH-neutral stone cleaner and a soft, damp cloth. Avoid acidic cleaners, vinegar, citrus-based products, or anything abrasive — the polished finish is particularly vulnerable to etching from acids, which can dull or cloud the reflective surface permanently.

Installation: Use white polymer-modified thinset mortar to prevent grey adhesive from telegraphing through the light stone. Apply thinset to both the substrate and the back of the molding for full coverage and maximum adhesion. Use non-sanded grout for tight joints and ensure the curved profile is level and flush with adjoining field tile edges before the adhesive sets.

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.

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.
