Columbia's Lewis Walnut 5" Engineered flooring comes in three semi-gloss shades of Walnut hardwoods - Natural, Mocha, and Hazelnut. This 5-ply wood floor can be glued, stapled, floated, or nailed onto any level of your home. The kissed edges have the look of square edges but help hide unevenness in the subfloor. These 1/2" planks have fine graining and come with a 25-year residential warranty.
