For a much more in depth look into Fiberglass pools and pool ownership in general we invite you to dive into the largest collection of swimming pool Q&A on the internet. River Pools and Spas have an amazing wealth of knowledge, and we would love to share it with you. You owe it to yourself to visit their Learning Center before you buy a pool.
One of the big mistakes I see from homeowners is that they price themselves out of a pool because of all the options. During the initial planning portion of your project, plan for future options. Leave room for more decking, plumb for future water features, plumb for a slide, leave room for that salt system, plan for a pool house/shed, landscape next year, get your winter cover in the fall, or leave that pool sweep for next spring. Be careful not to price yourself out of a pool with all the extras!
