There are basically two types of above ground swimming pools, hard-sided pools and inflatable pools with soft sides.

Hard-sided pools:

Hard-sided pools are available in several varieties of depths and sizes. These hard-sided pools are generally oval (egg shaped) or round in shape with a sheet metal frame. The most common depth is approximately 4 - 4 ½ feet. For stabilization, one piece of flexible metal wall with a sheet metal rail is attached to the top. The top rail is attached to the inserted vinyl liner so that the water is contained. A metal-sided pool is difficult to assemble, as it requires more detailed ground preparation.

Soft-sided pools:

Soft-sided pools have become ever more popular over the last decade. These above ground pools are available in both rectangular and round shapes, with the rectangular shape being more popular. These pools also have metal frames, and are available in a variety of depths and sizes. These pools are known for their strength and durability and are cheaper than hard-sided pools. They are a great way to have a customized pool as they can be built in large sizes. Soft-sided pools can be placed on almost any surface. They can be placed on dirt, grass, sand, concrete and even gravel. The pools have tolerance up to 3” out of line on each level. The pool liner material which is used in these pools is similar to that used in bullet proof vests. This makes the pool liner puncture resistant and durable. Soft-sided pools can be assembled within a few hours.

Both hard-sided and soft-sided pools require a filter and an electric pump to circulate the water. Other desirable accessories may include an automatic pool cleaner, automatic chlorinator, pool heater , a swimming pool light or even a swimming pool slide. Above ground pools are easier to install and are cheaper in price compared to in-ground swimming pools.
