Transforming old kitchen cupboards involves understanding their functionality and materials, selecting appropriate finishes and hardware, and enhancing them with accessories. Base, wall, corner, and pantry cabinets offer varied storage solutions. Wood and laminate provide durability and style options. Paint, stain, and glaze contribute to the desired aesthetic. Knobs, pulls, and handles improve accessibility and aesthetics. Shelves, drawer dividers, lazy Susans, roll-out shelves, and lighting elevate functionality and organization.
