The only difference between these two rooms, and the rest of the house, is that there is more moisture generated in these two rooms. If spills are cleaned up when they happen, and water is not left standing, then wood floors are as good as any other flooring material. If you leave puddles of water to dry on their own, then an inorganic inert flooring material may be a better choice. The biggest danger is not any surface abuse, but in trapping water between the finish floor and the subfloor, which could occur with any material. The trapped moisture cannot dry out, and this leads to an environment that promotes mold and mildew growth. Cork floors and floating floors offer slight cushioning underfoot, and are recommended for kitchens, exercise rooms, or any room where you’re on your feet most of the time.
