Grande Marina Oak Medium Grey Waterproof WPC | COREtec Floors

What is Grande Marina Oak?

Grande Marina Oak is a rigid, wood-look WPC floor in a soft warm-grey greige-taupe shade, with a heavy-duty, high-traffic wear layer for a durable, easy-care finish.

Is it waterproof?

Yes — 100% waterproof. Powder-room splashes, daily wet feet, and towel drops wipe up without harm when cleaned promptly. Indoor use only — not for installation inside showers or wet rooms, and outdoor installation is not approved.

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

Grande Marina Oak has a 30 mil wear layer — equivalent to 0.76 mm — ideal for heavy residential use and many commercial applications, so you get exceptional protection against scratches, scuffs, and everyday wear. A notably thick, hard-wearing surface for its class.

Will it hold up to daily life?

Kitchen stress test: dropped cutlery, pans slid from oven to counter, refrigerator casters, and dishwasher spray — Grande Marina Oak's 30 mil wear layer and finish handle the spills, dropped pots, and dragged stools of daily kitchen use, and wipe clean with a vinyl-safe cleaner.

What does the plank surface look like?

Up close the plank surface is where Grande Marina Oak earns its character. A broad, open cathedral grain runs down the middle of each board, with a strong central figure and swirling peaks that give the plank real movement. Fine mineral streaks thread through that figure, and here and there a small knot breaks up the field -- sparse and small, never busy. The variation from board to board is strong, so laid out as a floor no two planks look quite alike, which keeps a wide expanse of Grande Marina Oak from falling into an obvious repeat.

Quiet enough upstairs or in a condo?

There's no separate underlayment to buy and no pad to choose. Grande Marina 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 Marina 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?

In the room it was photographed in, Grande Marina Oak sits under soft midday daylight from real windows, and that even, natural light is what this greige-taupe likes best. The daylight lifts the warm side of the color so it reads soft and open rather than a flat grey, and against bright white walls and trim it looks clean and fresh. Because the tone is a light medium, it keeps a room feeling larger and brighter, which is a good match for a compact apartment. Pair Grande Marina Oak with cool greys and crisp white for a calm Scandinavian scheme, or bring in natural textures and greenery if you want a softer, warmer feel.
