Oak hardwood flooring is the most common wood floor in North America, especially red oak. Red oak is the name of the tree, not the color of the wood. A red oak floor is a surface that will hold up to wear and use. Due to its hardness, red oak resists dents, an important consideration if you're not planning to use area rugs. Oak hardwood flooring holds wood stains evenly and comes in a wide variety of stain colors. It can be light or dark, but its distinctive grain pattern is almost always obvious.
