Product Overview
Penny Marble Large Green 11.75" x 12" Mosaic Tile scales up classic circular geometry with rich botanical color and luxury natural stone depth. Crafted from genuine green marble, each mesh-backed sheet features oversized penny round chips (approx. 1.25" to 1.5" diameter) arranged in a continuous honeycomb grid.
The larger chip proportion highlights the stone's organic character—displaying an expressive palette of emerald, mint, and sage green with distinct white and crystalline veining. Mounted on flexible mesh backing sheets (~0.98 sq. ft. per sheet), this large penny round mosaic offers a bold, contemporary twist on traditional small-chip mosaics while providing natural slip resistance and smooth coverage across shower floors, accent walls, and backsplashes.

Shower Niches & Feature Panels: Serves as an eye-catching, organic backdrop inside recessed shower cutouts, window ledges, and fireplace surrounds.
Installation & Handling Guidelines
⚠️ IMPORTANT: NATURAL STONE PRE-SEALING & MORTAR PROTOCOL
-
Pre-Sealing Essential: Green marble is a porous natural stone. Apply a high-quality penetrating natural stone sealer to the mosaic sheets prior to grouting to guard against grout haze and pigment absorption.
-
White Thin-Set Mortar Required: Always set light and colored natural marble using a polymer-modified pure white thin-set mortar (ANSI A118.4). Gray thinset can shadow through translucent stone chips and alter the green color balance.
-
Non-Sanded Grout Selection: Maintain a 1/16" to 1/8" grout joint. Use a non-sanded grout or high-performance flexible grout formulated for delicate natural stone to avoid scratching the marble face during grouting.
-
Dry Laying & Color Blending: Natural green marble exhibits expressive tonal shifts across boxes. Open multiple boxes and dry-lay sheets before setting to blend mint, sage, and deep green tones evenly.
Care & Maintenance
-
Routine Cleaning: Clean regularly using warm water and a neutral pH natural stone cleaner. Avoid acidic cleaners, vinegar, bleach, lemon juice, or abrasive scrubbers, which will etch 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.
Design Profile
-
Aesthetic Inspiration: Modern Organic, Art Deco Revival, Botanical Spa, Contemporary Luxury.
-
Visual Advantage: The oversized circular geometry delivers a more modern, impactful visual scale than traditional small penny tiles while showcasing rich green mineral movement.

Frequently Asked Questions
Does Large Green Marble Penny Round mosaic tile require sealing?
Yes. As genuine natural marble, it is porous and must be sealed with a penetrating stone sealer prior to grouting and maintained periodically over time.
Is this large penny marble tile safe for shower floors?
Yes. The circular chip layout provides plenty of grout lines to ensure excellent slip resistance underfoot in wet shower environments.
Why is white thinset mortar required for installation?
Green marble can display slight translucency. Standard gray thinset mortar can show through the stone, dulling its rich green hues or causing dark shadows across the chips.
