Grande Willis Oak Medium Grey Waterproof WPC | COREtec Floors

What is Grande Willis Oak?

Grande Willis Oak is a rigid, wood-look WPC floor in a warm medium brown shade, with a thick, heavy-wear surface for a simple, carefree finish.

Is it waterproof?

Yes — 100% waterproof. Everyday spills, pet accidents, and mop water won't swell, warp, or delaminate the planks when wiped up promptly; standing water should still be cleaned up quickly. Not approved for outdoor installation; test the subfloor for moisture before installing.

How durable is it, and what traffic can it take?

Grande Willis Oak features a 30 mil wear layer — approximately 0.76 mm — built for heavy residential use and many commercial applications, offering exceptional protection against scratches, scuffs, and everyday wear. It's among the thicker wear layers commonly found in WPC flooring.

Will it hold up to daily life?

Grande Willis Oak's 30 mil wear layer and finish are rated for pet claws, chair legs, dragged furniture, and heavy daily traffic — the scratch resistance that matters in kitchens, entryways, and pet households where foot and paw traffic concentrates.

What does the plank surface look like?

Up close, the plank surface shows long grain lines running nearly the full length of the board, with an open, flowing figure and enough contrast to give each plank its own character. Several small, tight knots sit scattered across the boards at a moderate density, and dark mineral streaking threads through the grain here and there. The board-to-board variation is pronounced, so a laid floor of Grande Willis Oak looks varied rather than uniform, a detailed wood-grain print with real depth, not a flat repeat.

Quiet enough upstairs or in a condo?

There's no separate underlayment to buy and no pad to choose. Grande Willis Oak's factory-attached acoustic pad comes bonded to every plank and dampens footfall noise throughout the home — one less material decision and one less install step.

Is it safe for indoor air?

Yes — Grande Willis Oak carries GREENGUARD Gold certification, independently tested for low chemical emissions. That matters most for households with allergies, asthma, or young children.

Will this color work in my room?

Under the bright midday light coming through the room's many windows, Grande Willis Oak's warm brown lifts while its taupe-grey undertone stays quiet, so the floor reads clean and open rather than heavy. A medium tone like this takes strong daylight well, so it won't wash out the way a pale floor can, and the warmth keeps a white-walled room from feeling cold. In a bright, south-facing living room expect the brown to feel a little warmer through the afternoon; in softer or cooler light it leans toward its taupe-grey side. It pairs naturally with cool whites and a teal accent or two.
