COREtec Grande Lotte Oak is a 15 mm WPC luxury vinyl plank from the COREtec Originals Premium collection, 9 inches wide in mixed 28", 55", and 82" lengths. One carton covers 20.67 square feet, and project quantities are quoted individually.
A warm oak that stays warm without going orange
Lotte Oak is a warm light-to-medium oak with honey and tan tones running through an oak grain pattern. The design layer mixes straight grain with occasional cathedral figuring, and pale streaks cut across the darker passages in a way that keeps the floor from looking uniform or printed. There is a subtle limed quality to the lighter areas, and that is what stops the warmth from tipping into the orange or yellow of older honey-oak floors.
Embossed-in-register texturing aligns the surface texture with the printed grain, so the plank feels like brushed oak underfoot rather than like a texture running independently across an image. Enhanced painted bevels outline every board, which keeps each plank defined even at this size.
One caution on color, because it costs people money. No screen renders flooring accurately, including ours. Order a sample and look at it in the actual room, in morning daylight and again under your evening lamps, next to the cabinets and trim that are staying.
What Lotte Oak pairs with
Warm neutrals are having a long run in residential design, and Lotte Oak sits in the middle of the shift away from grey flooring. It pairs naturally with white and off-white cabinetry, natural stone counters, brass or matte black hardware, and the linen, jute, and rattan textures that go with a modern organic palette. Against sage, clay, or muted olive walls it holds more depth.
The warm tone also does real work in north-facing rooms and finished basements, where limited natural light can make a cooler floor read flat.
Wide planks show more of each board's variation than narrow ones do. Across a large floor that reads as natural movement, which is the point of the format. If you want a uniform, low-variation look, a narrower plank in a more consistent visual will get you closer.
Where the 82-inch plank earns its price
Scale is what separates Grande from the rest of COREtec Originals. An 82-inch plank measures 6 feet 10 inches. Lay that across a 12-foot room and two planks plus a cut piece span the width, where a standard 48-inch plank needs three planks and a cut. Fewer end seams, longer uninterrupted runs, and a floor that carries the eye across a room instead of breaking it into segments.
Large open-plan living areas, primary bedrooms, and long hallways are where that pays off. Short rooms cut too many boards to show the format, so in narrow spaces like galley kitchens and entryways, run the planks along the longer dimension to keep the seam count down. If your largest room sits under roughly 11 feet on its short dimension, a 7-inch-wide COREtec Originals Premium plank gives you the same core and the same wear layer for less per square foot.
Every carton holds all three lengths, 28", 55", and 82". The mixed lengths let seams stagger naturally without cutting every board. Installers used to uniform-length vinyl sometimes try to plan a pattern around it; the random distribution is the intended look, and fighting it produces more waste rather than a better floor.
A 15 mm WPC core, not SPC
Underneath the visual, this is a 15 mm plank built on a waterproof foamed WPC core, and it feels meaningfully different from the SPC products that dominate this price bracket. The foamed core is softer and warmer underfoot, and the factory-attached cork underlayment adds acoustic dampening that matters on second floors and over concrete slabs.
SPC is denser, thinner, and holds up better against concentrated point loads: a piano leg, a loaded safe, a hard-caster desk chair. WPC trades some of that dent resistance for comfort and quiet. If sound and underfoot feel matter more to you than maximum dent resistance, WPC is the reason people choose COREtec Originals.
At the surface, a 30 mil wear layer under a UV acrylic finish is heavy enough to carry a 10 Year Medium Commercial Limited Warranty alongside Lifetime Residential coverage. Medium commercial is a higher traffic rating than light commercial, which makes this a workable specification for home offices, boutiques, and similar light commercial spaces as readily as for a family home.
A 30 mil wear layer resists abrasion and wearing through. It does not make the surface scratch-proof. Dragged furniture, bare chair feet, and grit tracked in on shoes will mark any vinyl floor. Felt pads and a doormat handle most of it.
The floor is GREENGUARD Gold certified for low VOC emissions, installs above, on, or below grade, and needs no acclimation period.
What 15 mm means for your doors and appliances
At 0.59 inches, Grande is among the thicker floating floors sold today. Check that number against four things before your order ships.
Interior doors need about 5/8 inch of clearance at the bottom or they will drag. Doors can be trimmed, so treat this as a budget item rather than a dealbreaker.
Dishwashers and slide-in ranges sit in a fixed opening under the countertop. Adding 0.59 inches of floor underneath can make future removal difficult, and in tight installations the appliance may not slide back in at all. Measure your current clearance now, not after the floor is down.
Cabinet toe kicks lose more than half an inch of visible height, because a floating floor goes over the existing subfloor rather than under the cabinets. On a long run that changes the proportion noticeably.
