Type of wood: Different species of wood have different hardness, grain patterns, and color. Oak, maple, and cherry are popular choices due to their durability and attractive look. Exotic woods like Brazilian cherry or mahogany are often more expensive but offer unique colors and patterns.
Solid vs. Engineered: Solid hardwood is a single piece of wood, whereas engineered hardwood is a veneer of real wood bonded to several layers of less expensive, high-density material. Your choice may depend on factors like your budget, location in the home, and subfloor material.
Finish: Prefinished hardwood flooring has been sanded, stained, and sealed at the factory, whereas unfinished flooring is finished on site. Prefinished flooring is more convenient, but unfinished flooring offers more customization options.
Grade: The grade of the wood describes its appearance, such as the number of knots or other natural features. Higher grade woods are more uniform in appearance but often more expensive.
