Product Overview

Crafted from genuine Grassland green marble, each sheet features classic 3/4-inch to 1-inch penny round chips arranged in a honeycomb mosaic layout.

Recommended Applications
-
Shower Pans & Bathroom Floors: The circular penny round format creates an abundant grid of grout joints, offering superior underfoot slip resistance in wet shower enclosures and powder rooms.
-
Kitchen Backsplashes & Feature Walls: Adds soft botanical green tones and tactile circular geometry behind ranges, prep sinks, and vanity mirrors.
-
Shower Niches & Accent Features: 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: Grassland 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 jade, mint, and moss 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, Botanical Spa, Japanese Wabi-Sabi, Soft Scandinavian.
-
Visual Advantage: The fluid penny round geometry softens rigid room angles, while soft sage and jade marble tones introduce a tranquil, nature-inspired focal point.
-
Complementary Finishes: Brushed brass or warm gold hardware, natural white oak or walnut millwork, polished nickel fixtures, and creamy quartz or light gray marble countertops.
Frequently Asked Questions
Does Penny Marble Grassland 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 penny marble tile safe for shower floors?
Yes. Penny round mosaics are among the best choices for shower floors because the small circular chips create frequent grout lines that significantly enhance slip resistance when wet.
Why is white thinset mortar required for installation?
Grassland marble can display slight translucency. Standard gray thinset mortar can show through the stone, dulling its soft green hues or causing dark shadows across the chips.
