Countertops are essential elements in kitchens and bathrooms, made from various materials such as natural stone (granite, soapstone), quartz, cultured marble, solid surface (acrylic), laminate, ceramic tiles, and engineered stone. The choice of material significantly affects indoor air quality, energy consumption, and environmental impact. Natural stone and quartz are preferred for their durability and lower chemical emissions, while synthetic options like laminate and cultured marble can emit VOCs and formaldehyde. Accessory products like adhesives and sealers can also introduce harmful substances, such as PFAS in stone sealers. Production of synthetic countertops often involves high energy consumption and petroleum-based materials, contributing to a larger carbon footprint compared to natural stone.
