Use the following guide to learn about some of the most popular types of pools. Each option comes with its own pros, cons, and special considerations that should factor into your decision.

1. Above-Ground Pools

Generally the most economical option, above-ground pools sit on the surface of your yard, sometimes with a deck or patio surrounding them. Most above-ground pools are constructed with aluminum, resin, or steel sidings and vinyl liners. Patterned walls are available. You can often assemble and dismantle this type of pool with relative ease as a DIY project, or many retailers offer delivery and installation. Above-ground pools are also suitable for yards with limited access. They arrive in pieces that can easily be carried to the site for assembly.

Advantages of Above-Ground Pools

Above-ground pools are generally less expensive and easier to build than other types of pools. Here are some of the main advantages:

Above-ground versions are the most affordable type of pool.Some options are temporary structures, so you can take them with you if you move.Available in several shapes and sizes, they’re suitable for small yards.Assembling and disassembling an above-ground pool is relatively easy.

Disadvantages of Above-Ground Pools

You should also consider these downsides before choosing an above-ground pool:

Although they come in a variety of shapes and sizes, you are typically limited to the designs offered by the manufacturers.Above-ground pools can be difficult to disguise in a landscape, although carefully planned patios and decks can help blend them into your yard.Their lifespan is not as long as in-ground pools. Vinyl liners typically need replacing every five years.

Also popular are the most basic above-ground pools, which are easily filled with a garden hose and stored away when not in use. Because they require no filtration equipment, they must be regularly drained, cleaned, and refilled to provide a clean swimming environment.

2. In-Ground Pools

In-ground pools are permanent structures built directly into the landscape. They come in several varieties, with concrete, fiberglass, and vinyl-liners being the most common types. Your contractor can work with you on the choice of construction. Materials are typically chosen for strength and flexibility.

Fiberglass Pools

These are usually made by the manufacturer and delivered in one piece. Fiberglass pools are typically more flexible than concrete pools, making them a good choice in earthquake-prone areas. Fiberglass panel pools, which are constructed on-site, are another option that allows more design flexibility.

Concrete Pools

Often the most costly to build, concrete pools are poured on-site, allowing you to custom-design virtually any shape or size. Finishes include plaster, paint, and specialty coating materials, such as Pebble Tec, and are available in a range of colors.

Vinyl-Liner Pools

These in-ground pools are built with panel walls that are fastened together and sit on a concrete foundation. A custom-made vinyl liner then covers the entire pool.

Advantages of In-Ground Pools

In-ground pools offer nearly endless opportunities to customize the size, shape, and style to create your dream pool. These are the main advantages:

Most in-ground pools can be designed to fit any shape or size yard and accommodate your specific needs, such as depth for diving or fitness swimming.They can be designed easily into the landscape.There are several accessories and features available, such as diving boards, slides, water games, water fountains, and specialty lighting.

Disadvantages of In-Ground Pools

This type of pool also comes with a few significant downsides:

In-ground pools are typically more costly to build.The construction duration can be lengthy.Because the water surface is near ground-level, in-ground pools can pose a greater safety risk for young kids or pets.

3. Infinity Pools

Typically custom-made to highlight a view, infinity pools feature one or more walls with a vanishing-edge design, which sits just below the pool’s water level. This allows water to flow over the wall, creating the illusion that the water has no bounds. This type of pool is often used on sites with a steep drop-off, and showcases views of mountains, lakes, ocean, and other striking landscapes. Because of their specialized design requirements, infinity pools can be very costly to build and maintain.

4. Lap Pools

If your primary reason for owning a pool is fitness, a lap pool can be a smart investment. Designed specifically for swimming laps, this type of in-ground pool is long, narrow, and typically rectangular. Requiring minimal space, lap pools are ideal for small yards. Most lap pools offer at least 40 feet of straight, unobstructed swimming space to limit the need for frequent turns. For a single swimmer, the width of a lap pool can be as little as 8 feet. The construction considerations are similar to that of other in-ground pools.

5. Swim Spas

Swim spas are another type of pool that’s well suited for fitness use. A hybrid of a pool and spa, swim spas have water jets that allow the user to swim against a constant flow of water. Great for small yards, some swim spas span as little as 12 feet. Because the swimmer isn’t actually moving through the water, the dimensions of the pool can be much smaller. They can also be heated for dual use as a spa and a swim spa.

6. Hot Tubs and Spas

Hot tubs and spas are small, heated pools intended for relaxation or hydrotherapy. The portable, above-ground version is typically called a hot tub, while a home spa refers to an in-ground model, which is often built in conjunction with an in-ground pool. Thanks to their smaller size, hot tubs and spas are typically less expensive to install and maintain, compared to other types of pools. However, their compact dimensions also limit their use.
