Concrete pools have the longest life span. As long as you properly maintain your concrete pool, you can expect it to last 50 to 100 years. That said, you will need to resurface your concrete pool as it ages. Fiberglass is durable, but fiberglass pools generally only last around 25 to 30 years. That said, some high-end fiberglass pools can last more than 50 years if they’re well-maintained.

Spools can come as small as 10 x 6 feet, so they don’t take up a lot of room in your yard. You’ll want to plan for pool decking, fencing, and other features that may take additional space, but for the most part, a spool’s small footprint makes it a great choice when you don’t have much yard space to spare.

An above-ground pool with a deck can increase your home's value by as much as 4% to 7%, but it depends on your local climate, potential buyers, and the size and condition of your pool. Some buyers see a pool as a liability instead of a luxury, especially if it's at the end of its life span. In general, it's best to add a pool and deck to your property if it will bring you enjoyment—not because it raises the value of your home.

In most states, it is a legal requirement to have a fence around your pool to protect both swimmers and pool owners. These laws can vary by state, city, and county, so you must research the specific regulations in your area before installation. The rules may also differ for inground versus above-ground pools, with inground pools typically requiring a full fence. Additionally, most homeowners' insurance providers will require a fence around a residential pool before providing coverage. As a general rule, it's always best to have a fence for everyone's safety.
