Countertops are horizontal surfaces that are installed in kitchens, bathrooms, and other areas of the home for a variety of purposes, including preparing and cooking food, washing dishes and hands, and storing and using small appliances. 

Countertops are typically made of a durable, water-resistant material such as stone, concrete, or man-made materials like quartz or solid surface. They are typically installed on top of cabinets or other base units to provide a work surface. Countertops come in a wide range of materials, colors, and styles to suit different design preferences and budgets.
