The formula you’ll use to measure your pool will differ based on the shape of your pool. For a rectangular pool, you’ll use the following formula to find the size in gallons: length x width x depth x 7.5. If the depth changes from one end of your pool to the other, take the average by finding the depth at the deepest and most shallow points and dividing that number by two. Circular and oval pools require different, more complicated formulas, which can be found in this article.

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.

A well-built and well-maintained concrete pool should last anywhere from 50 to 75 years. Concrete is prone to cracking, so winterization and regular pool repairs are particularly important. Water can seep into existing cracks, freeze, and make them worse. Most homeowners should resurface their concrete every few years to maintain their pool’s lifespan. 

There are some disadvantages to a salt water pool. Besides costing slightly more than chlorine pools, salt water pools require a lot of salt. It's also harder to find a professional with salt water pool experience to do minor maintenance and repairs. Salt water can also damage some materials, so you’ll need to use specific heating, fixtures, lighting, liners, and masonry when building a salt water pool.
