Deciding on the type of inground pool to install is a big decision. There are many factors to consider, including cost, size, shape, and maintenance requirements. When it comes to ease of maintenance, fiberglass pools are often the best choice. Unlike concrete pools, which require regular acid washes to prevent stains, fiberglass pools are non-porous and highly resistant to staining. In addition, fiberglass pools are less likely to crack or chip, and they don't require the same level of chemical treatment as concrete pools. As a result, fiberglass pools offer a lower level of maintenance and can provide years of enjoyment with minimal hassle.
