InGround Pools: Everything You Need to Know

In places like Australia where days can get really hot, one can find solace in a resort-style home that provides relief from the discomforts brought by the weather. And while many are planning for a pool installation to have a backyard swimming pool,  it’s important to keep in mind the best options: an inground and an aboveground pool.

Aboveground pools used to be the most popular choice among households in Australia. However in the recent years, there has been an increase among homes with inground pools due to the benefits that they bring.

Inground pools are the best choice for big families, or for those who usually host pool parties, or even for people who do regular pool workouts. With its versatility and large size, inground pool could be considered as the best pool choice for homeowners.

In this article, we cover essential information about inground pools. Get to know the differences between inground and aboveground pools, the types of inground pools and their costs.

What is an Inground Swimming pool

Inground pools are essentially the type of pools that are dug up from the ground. The above ground pools, on the other hand, sit on the ground with sturdy walls to contain the water. In terms of function, the two are the same. However, inground pools are considerably larger and have more features than the other one.

To give you a better perspective, here’s a quick comparison between Inground and Aboveground swimming pools.


Above ground pools last up to 15 years and the liners up to 9 years.

Inground Pools last up to 20 years (depending on the type) and the liners up to 11 years.  


The two do not differ much in terms of maintenance demand. However, a concrete inground pool needs to be resurfaced every 10 years while the above ground pool’s liners have to be replaced every 5 to 9 years.


Inground pools are more costly than above ground pools. However the cost pales in comparison to its quality, size and features.

Three Main Types of Inground Pools

Three Main Types of Inground Pools

There are three main types of inground pools depending on the material used in construction.

Concrete Pools

It is a fully custom-built pool that can be formed in any shape such as following the shape of your backyard. It is also called gunite or shotcrete pool because a concrete is shot onto the steel reinforced walls. Its surface is  either tiled or plastered and finished with a desired texture.

Among the three types of inground pools, concrete ones take longest to install. It can take up to 3 months to finish such project.


Customisable, Strong and durable,

Can be remodeled and updated


More expensive, Longer to install

Vinyl-lined Pool        

The most affordable of the three, vinyl-lined pools are made from a prefabricated liner that fits into the reinforced wall frame of the pool. Most vinyl pools are rectangular in shape as it is only slightly customisable. However, there is a wide option of colors that can suit your personal taste and style.

One of its drawbacks is that it’s not as strong as the concrete pool. Hence, it is more expensive and difficult to include additional pool options. Also, the liners are sensitive to sharp objects. A 20-30mm thick liner is the safest choice.

Only slightly customisable

Not as strong as the concrete pool

Can easily get punctured by sharp objects

Fibreglass Pools

Fibreglass pools are made of preformed bowl shaped piece that is transported and installed in your pool project. As such, customisation is very difficult to do to that point that it is almost considered not customisable. It lasts longer but costs a little more than the vinyl pool.

On the brighter side, it is a very durable material with a stain-resistant finishing. Unlike concrete, its smooth gel coat finish harbors less algae, hence it is easier to maintain.

Not customisable

No control on the placement of fittings

With a good background about the three types of inground pools, the most important question is, “What about cost?”

The Cost of Inground Pools

The Cost of Inground Pools

To be honest, there is no precise answer to this question as there are factors that add up to the cost of a swimming pool project. These factors include:

Size. The size of the pool has the largest share in the price tag. It is the biggest factor in calculating the price.

Depth. As inground pools include an intensive excavation, the deeper the pool, the more expensive is its cost, as it requires more labor and materials.

Added features. Adding unnecessary features definitely increases costs. For example, pool decks are the most expensive addition to a swimming pool project. It can even cost higher than the pool itself.

However, in terms of the type of material used, the price of inground pools is discussed below:


Price range:  $50,000 to $100,000

Maintenance Cost (over 10 year period): $27,000.00

Concrete or gunite is considered a premium material, thus concrete pool generally costs way more than vinyl or fibreglass (although a first rate fibreglass pool could cost more than concrete). Turn-key projects could cost $50,000 to $100,000. However since you don’t need to replace its liners, the cost of concrete pool becomes reasonable in the long run.


Price range: $25,000 to $50,000

Maintenance Cost (over 10 year period): $11,500

Vinyl is by far, the cheapest inground pool. Installation of vinyl pool by a professional pool builder costs around $25,000 to $50,000. However, some owners who have the skill, tools and willingness can have DIY vinyl pool, and altogether save thousands of dollars.  


Price range: $45,000 to $85,000

Maintenance Cost (over 10 year period): $3,750

Fibreglass pools generally cost lower than a concrete pool, with an average price of $45,000 to $85,000. However, it can cost much more if the project requires extra features, elaborate design or extensive retaining walls. Of the three types, it is the cheapest to maintain.
