Product Overview

1" x 12" Carrara White Marble Quarter-Round Trim Molding provides an elegant, smooth finishing edge for natural stone tile installations. Crafted from genuine Italian Bianco Carrara marble, this pencil-like quarter-round profile features a soft white background accented by subtle feather-like gray veining and a smooth polished finish.

Ideal for capping tile wainscoting, smoothing transitions along backsplash corners, or framing shower niches, this quarter-round trim creates a clean, rounded border that conceals raw tile edges while protecting corners against chipping and wear.

Recommended Applications

  • Kitchen Backsplash Transitions: Provides a polished, rounded edge where tile backsplashes end against drywalls or cabinetry.

  • Shower Niches & Corners: Smooths vertical and horizontal turns inside shower cutouts, window ledges, and accent walls.

  • Wainscoting & Accent Wall Cap: Serves as a decorative top rail trim for half-height marble tile walls in powder rooms and primary baths.

Design Profile

  • Aesthetic Inspiration: Italian Luxury, Classic Modern, European Bistro, Modern Organic.

  • Visual Advantage: Softens sharp tile borders and creates architectural continuity across marble tile backsplashes and shower walls.

  • Complementary Finishes: Carrara marble field tiles (subway, hexagon, mosaic), polished chrome hardware, warm white cabinetry, and gray quartz countertops.

Colors and textures may vary slightly between tile batches due to natural manufacturing variations. For a clear representation, we recommend ordering a sample.

WARNING: This product can expose you to chemicals including crystalline silica (airborne particles of respirable size) in dust created during fabrication/installation if the product is dry cut, ground, or pulverized, which are known to the State of California to cause cancer.

Installation and Handling Guidelines

⚠️ IMPORTANT: NATURAL STONE PRE-SEALING & MORTAR PROTOCOL

  • Pre-Sealing Essential: Carrara marble is a natural porous stone. Apply a penetrating natural stone sealer to the trim pieces prior to grouting to prevent grout haze and pigment absorption.

  • Pure White Thin-Set Mortar Required: Set Carrara marble trim using a polymer-modified pure white thin-set mortar (ANSI A118.4). Gray mortars will shadow through translucent light marble and permanently discolor the stone.

  • Mitering Corners: Cut 45-degree corner miters carefully using a wet tile saw equipped with a continuous-rim diamond blade designed for marble.

  • Grout Joint Placement: Butt trim pieces neatly along the finished edge of the main tile field, maintaining a consistent 1/16" to 1/8" grout line.

Care and Maintenance

  • Routine Cleaning: Clean regularly with warm water and a neutral pH natural stone cleaner. Avoid vinegar, bleach, lemon juice, or abrasive scrubbers, which will etch polished marble surfaces.

  • Periodic Resealing: Reapply a quality penetrating stone sealer every 1 to 2 years (or more frequently in heavy shower wet areas) to maintain water repellency and stain defense.

Frequently Asked Questions

Does Carrara White quarter-round trim require sealing?

Yes. Being natural marble, it is porous and should be sealed with a penetrating stone sealer before grouting and maintained periodically.

Can this quarter-round trim be used in wet areas like showers?

Yes. It is widely used to trim shower niches, window returns, and wall edges, provided it is set with white thinset mortar and properly sealed.

Why is white mortar required for installation?

Carrara marble is slightly translucent. Gray thin-set mortar can show through the stone, causing dark discoloration or shadows along the trim.
