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.

Technically, you can fill in a pool yourself—with the caveat that filling in a pool requires the ability to drain the pool properly and move a substantial amount of dirt, which aren’t beginner DIY skills. If you want to fill in a pool, you’re better off hiring a local pool removal professional.

The most expensive part of building a pool is typically the excavation and labor, which can account for 25% to 50% of the total project cost. This is particularly true for inground pools that require significant excavation, potentially including the rental of large equipment, and extensive construction labor. In contrast, above-ground pools are generally less expensive as they typically do not require excavation and can be installed much more quickly. Concrete in-ground pools are among the most labor-intensive options.

Rectangular pools are the most popular inground pool shape, due to their adaptability to different uses, from swimming laps to hosting parties. These pools can easily include other sought-after features, such as tanning ledges, waterfalls, sport nets, and more. Rectangular pools are also often easier to install and maintain, and prefabricated rectangular pools generally have a shorter installation time, so you can start enjoying your pool faster.
