There are a few different factors that will determine the cost of installing an inground pool, such as the size of the pool, the materials used, and the level of customization. However, in general, fiberglass pools are the cheapest option, followed by vinyl pools and then concrete pools. If you're looking for a budget-friendly option, I would recommend vinyl or fiberglass pools. Vinyl is generally cheaper than fiberglass, but it may not be as durable over time. Fiberglass is more expensive than vinyl but is more durable and requires less maintenance.

It depends on the size of the pool and the insurance company. Typically, an inground pool will add about $25-$50 to a homeowner's insurance policy.
