Shaker and flat-panel cabinets can both last 20 years or more. Durability depends on construction, materials, and finish, not door style. Shaker doors are more forgiving of everyday wear because their framed profile hides minor scuffs. Flat-panel doors have fewer places for grime to collect, so they are easier to keep clean. For South Florida kitchens, humidity resistance, a quality core material, and proper installation matter more than the door profile you choose.
