COREtec CRT01 Natural Opula Waterproof Luxury Vinyl Tile Flooring 18" x 36"

The COREtec CRT01 Natural Opula Collection brings the timeless beauty of natural stone to any room in your home — without the weight, fragility, or maintenance demands of real travertine and marble. Each tile measures a generous 18 inches by 36 inches, delivering the large-format stone aesthetic that defines luxury interiors, on a foundation of COREtec's advanced WPC (Wood Plastic Composite) rigid core technology.

At 12mm thick with a premium 30-mil wear layer — one of the heaviest wear layers available in residential luxury vinyl tile — Natural Opula is engineered for exceptional durability and authentic stone replication. The 30-mil wear layer surpasses most residential LVT wear layer thicknesses, providing protection suited to the most demanding household environments. A 4-pattern repeat ensures natural variation across the floor surface, preventing the repetitive appearance that undermines the realism of lesser tile products.

Every tile features a pre-attached cork underlayment for natural sound absorption and a warmer, more comfortable feel underfoot compared to bare-bottom tile — addressing one of the most common complaints about hard tile surfaces. The collection is GREENGUARD Gold Certified, meeting the most stringent VOC emission standards for indoor air quality, and is backed by a Lifetime Residential Limited Wear Warranty.

With four distinct stone-inspired colorways — spanning warm travertines and dramatic marbles — COREtec CRT01 Natural Opula brings the visual richness of natural stone to kitchens, bathrooms, living areas, and basements with the practical performance that real stone simply cannot match.

Product Specifications

Why Choose COREtec CRT01 Natural Opula?

30-Mil Wear Layer — Premium Stone Protection At 30 mils, Natural Opula's wear layer is among the thickest available in residential luxury vinyl tile — providing exceptional scratch, scuff, and abrasion resistance that preserves the beauty of the stone surface for decades. This is the wear layer thickness that distinguishes a premium LVT from a standard one, delivering long-term surface integrity in the most active households.

18" x 36" Large-Format Stone Tile The 18" x 36" tile format replicates the scale of high-end natural stone installations — the kind typically found in luxury hotel lobbies, upscale kitchens, and designer bathrooms. At this size, grout lines are minimized and the visual flow of the stone pattern reads as intended, creating an expansive, seamless look that smaller tile formats cannot achieve.

100% Waterproof WPC Core COREtec's WPC rigid core is waterproof through the entire tile — not just the surface. Natural Opula will not warp, swell, or buckle from moisture, making it suitable for kitchens, bathrooms, wet rooms, and below-grade basement installations where real stone and ceramic tile require complex waterproofing membranes.

4-Pattern Repeat for Natural Stone Realism A 4-pattern repeat means four distinct tile surface images are used across the installation, preventing the repetitive, obviously-printed appearance that undermines stone realism in lower-quality LVT products. The result is a floor that reads as authentically varied natural stone rather than a repeated pattern.

Pre-Attached Cork Underlayment Every Natural Opula tile ships with a factory-attached cork underlayment — a significant advantage over bare-bottom LVT tiles. The cork layer provides natural sound absorption, thermal comfort, and a softer feel underfoot, addressing the acoustic and comfort limitations that make real stone tile impractical in many living spaces and upper-floor installations.

GREENGUARD Gold Certified — Indoor Air Quality GREENGUARD Gold is the most rigorous indoor air quality certification available for flooring products, independently testing for hundreds of VOCs including formaldehyde. At GreenFlooringSupply.com, GREENGUARD Gold certification is a core requirement — ensuring every COREtec product we carry is safe for families, children, pets, and individuals with chemical sensitivities from day one.

Lifetime Residential Limited Wear Warranty COREtec backs Natural Opula with a Lifetime Residential Limited Wear Warranty — a reflection of the long-term confidence that comes with a 30-mil wear layer and WPC rigid core construction.

Where COREtec CRT01 Natural Opula Performs Best

The large-format stone aesthetic of Natural Opula makes it a natural fit for kitchens and open-plan living areas where the uninterrupted visual flow of 18" x 36" tiles creates a sense of space and luxury. The 100% waterproof WPC core makes it equally practical in bathrooms and wet rooms where real stone requires costly waterproofing membranes and regular sealing maintenance.

For basements and below-grade installations, Natural Opula's WPC core handles moisture and temperature fluctuations that would crack or stain natural travertine and marble over time. The pre-attached cork underlayment also makes below-grade installations more comfortable underfoot — addressing the cold, hard quality that makes stone tile impractical in basement living spaces.

In entryways and mudrooms, the 30-mil wear layer handles the abrasive grit and moisture of high-traffic entry zones that quickly degrade thinner LVT products. And in commercial-adjacent spaces like home offices, studios, and showrooms, Natural Opula delivers a professional, upscale stone aesthetic with the durability to back it up.

Ideal Spaces: Kitchens · Bathrooms · Wet Rooms · Entryways · Basements · Living Rooms · Dining Areas · Home Offices · Laundry Rooms · Mudrooms

Installation Information

Floating (Click-Lock): Tiles click together and float over the subfloor — no adhesive required. Suitable over concrete, plywood, and most existing hard surface floors in good condition. Compatible with radiant heat systems. The pre-attached cork underlayment is included with every tile, so no separate underlayment purchase is needed.

Full Spread Glue Down: For applications requiring a fully adhered installation. Recommended for certain commercial applications or where maximum stability is required. Note: remove or do not use the attached cork underlayment for glue-down installations — follow COREtec's official installation guidelines.

The WPC rigid core's exceptional rigidity and subfloor bridging capability makes Natural Opula more forgiving over minor subfloor imperfections during floating installation than traditional ceramic or stone tile.

Always follow COREtec's official installation guidelines and acclimate tiles prior to installation. Contact us at 888-976-8166 for installation questions.

Frequently Asked Questions — COREtec CRT01 Natural Opula

Is COREtec CRT01 Natural Opula truly waterproof? Yes. Natural Opula features a 100% waterproof WPC core through the entire tile — not just the surface. It will not warp, swell, or buckle from moisture, making it suitable for kitchens, bathrooms, wet rooms, and below-grade basement installations.

How does Natural Opula compare to real travertine or marble tile? Real travertine and marble are porous, require regular sealing, can crack under impact, and are extremely cold and hard underfoot. Natural Opula replicates the visual beauty of natural stone with none of these limitations — it is waterproof, scratch-resistant, warmer underfoot thanks to the cork underlayment, and requires no sealing or special maintenance.

Does COREtec Natural Opula include an underlayment? Yes. Every tile ships with a factory pre-attached cork underlayment providing natural sound absorption, thermal comfort, and a softer feel underfoot compared to bare-bottom LVT tiles.

What is a 4-pattern repeat?
