Wood floors can be used in a kitchen area but must you should only use engineered hardwood and not solid hardwood. Engineered hardwood flooring is much more durable and able to withstand changes in temperature, humidity and moisture far better than solid wood flooring. This is solely due to the way it has been constructed. On the surface it looks just like solid wood, as the top layer of the plank is actually real wood, then underneath is layers of plywood to give it its dimensional strength and stability. Engineered hardwood flooring is a great alternative to solid wood flooring as it is more durable, less costly and still gives the timeless character and feel of a solid wood floor.
If you do decide to install engineered wood flooring into your kitchen, then you will still need to be careful and wipe away any water spills. By doing so you reduce the risk of the standing water possibly penetrating and damaging the floor's surface.
