Solid or engineered hardwood? Start with the room.
Both use real wood, but their construction differs. Solid hardwood is a single piece of wood. Engineered flooring has a wood surface supported by layers beneath it.
The product matters more than the label
Two engineered products can have different wear layers and installation requirements. Solid floors also vary by species, dimensions, and finish. Compare the specific products you are considering.
Check the installation conditions
Subfloor type, moisture, and the level of the home can affect suitability. Some engineered products allow installation methods that a particular solid floor does not. Follow the manufacturer's requirements rather than assuming one rule covers the whole category.
Do not confuse stability with waterproofing
Engineered construction can offer dimensional-stability advantages, but that does not make every engineered wood floor waterproof. Leaks and unsuitable moisture conditions can still damage flooring.
Ask about future maintenance
The ability to sand a floor depends on remaining usable material, condition, and manufacturer guidance. A real wood surface does not guarantee that an engineered floor can be refinished repeatedly.
Compare samples in your home
Look at grain, color, plank width, and sheen in the room's actual light. Consider adjoining floors and the transitions between them.
