Factors such as soil type, water table levels, and local climate can significantly influence the foundation requirements. Typically, a concrete base is recommended for its durability, but alternatives like polymer walls or fiberglass may also be suitable depending on your specific needs. It's essential to factor in costs, potential maintenance, and safety considerations when planning your pool installation.
