Above Ground Pools: Is This The Right Option For You?
A pool is a great investment for your property. It can boost lifestyle, create a space to entertain family and friends, and add serious appeal to your backyard. But what if an in-ground pool isn’t practical for your site — because of a slope, limited space, hard ground/bedrock, or the layout of your block?
Key Takeaways
- Above ground pools are a practical solution for sloping blocks, rocky terrain, tight access, and smaller backyards where in-ground excavation is difficult or costly.
- There are multiple “above ground” options: fully above ground, partially above ground, or in-ground depending on site levels and design goals.
- Fibreglass above-ground installs can work extremely well, but they must be engineered correctly with the right support (retaining walls / framing / backfill strategy).
- Costs depend heavily on materials, design complexity, access, and site works — so a site assessment is the fastest way to get clarity.
Searching For Your Dream Pool?
What is an above ground pool?
An above ground pool is any pool where the waterline (and pool structure) sits above natural ground level — either partially or fully. This approach is often used when a site isn’t ideal for a fully in-ground excavation, or when you want the pool deck to connect at a specific height off the home.
Why are above ground pools so popular?
Not all backyards have the perfect conditions for an in-ground pool. Whether it’s because of slope, uneven terrain, limited space, or ground conditions, an above ground pool can be the solution.
- Versatility: They can be designed to suit awkwardly shaped yards and challenging site conditions.
- Faster path to installation: In many cases, there is less excavation required compared to fully in-ground builds.
- Safety advantages: A higher entry point can reduce unplanned access for kids/pets (note: compliant fencing and gates are still essential).
- Potentially lower long-term costs: Depending on the pool type, above ground pools can require fewer chemicals and be simpler to maintain.
Above-ground vs partially above-ground vs in-ground (what’s the difference?)
In-ground pools
In-ground pools are the most common approach. They typically suit blocks with enough usable space, workable soil conditions, and a layout that allows excavation and access.
Partially above-ground pools
Partially above-ground pools are common on sloping blocks. The pool may be set into the ground on one side and raised on the other, using retaining walls, engineered supports, and decking/landscaping to create a clean finish.
Fully above-ground pools
Fully above-ground pools sit clearly above natural ground level. This can be used to reduce excavation costs, deal with difficult ground conditions, keep the pool above a potential flood-prone area, or achieve a specific look (for example, a raised deck connection off the house).
When does an above-ground fibreglass pool make sense?
Fibreglass pools are pre-constructed in factories and delivered to site, which makes them a popular choice for many installations — including above-ground applications. An above-ground fibreglass pool can be an excellent solution if:
- You have a sloping site and need the pool elevated to work with levels.
- You want the pool deck to connect at a higher level off the house or an existing patio.
- You want to avoid excessive excavation or your site conditions make digging difficult.
- You need the pool above a potential flood plain or want the structure elevated for site drainage reasons.
- You’re building on a hillside and want the downhill side exposed (with proper erosion control and engineering).
- You’re exploring more premium features such as infinity-edge styling or feature windows in the design concept.
Benefits of an above-ground fibreglass pool
1) Potential cost savings on excavation
Above-ground installations can reduce the need for deep excavation and large volumes of backfill, which may lower overall site works compared to a fully in-ground build (site dependent).
2) Convenience and faster progress (site dependent)
With less excavation required in many scenarios, above-ground installs can be more straightforward — particularly when the design works with the natural site levels instead of fighting them.
3) Strong durability (when installed correctly)
Fibreglass shells are manufactured to be strong and resilient. When installed with the right support and engineering, they provide excellent structural integrity and long-term performance.
4) Easier aesthetic customisation
Above-ground pools can be styled beautifully with decking, cladding, retaining walls, and landscaping. A raised deck can become a feature in itself — especially for entertaining areas.

Types of above ground pools (by material)
Above ground pools can be constructed from various materials. Each option has different pros, costs, lifespan, and maintenance needs.
Concrete above ground pools
Concrete pools are built on-site and can be designed to suit unusual layouts. They’re highly customisable, but they generally take longer to build and may require resurfacing over time.
Fibreglass above ground pools
Fibreglass pools are factory-made shells that are delivered to site. They’re known for durability and relatively low ongoing maintenance. If you’re exploring options, view our range of fibreglass pools.
Plastic or vinyl above ground pools
Plastic/vinyl pools are often the cheapest upfront option, but they can be less durable and may require more vigilance with maintenance depending on the system and build quality.
What you need to get right with above-ground fibreglass installs
This is the part that matters most: an above-ground fibreglass pool needs the correct structural support. While the shell arrives pre-constructed, the installation must be engineered so the pool is properly supported and finished safely.
- Support & retaining strategy: Above-ground installs typically require retaining walls / framed decking / engineered support to protect the shell and surrounding structure.
- Custom build considerations: Where required, ensure the design and shell selection supports the installation style you’re aiming for.
- Erosion control (hillside sites): If the downhill side is exposed, you must control erosion so backfill and soil stability aren’t compromised.
- Professional installation: Above-ground installs are not the place to “cut corners”. A professional will assess site conditions and recommend the safest, most durable approach.
Pricing: what affects above ground pool cost?
Above ground pools are often cheaper than fully in-ground pools, but price depends heavily on the material and the site works required.
- Material: Vinyl/plastic tends to be cheaper upfront. Concrete is often mid-range. Fibreglass is typically a higher upfront investment, often balanced by easier ongoing maintenance.
- Design complexity: Custom shapes, premium finishes, raised decking, and feature elements can increase cost.
- Site conditions: Access, slope, ground type, retaining requirements, and drainage needs all influence installation costs.
Permits and clearances
You will generally need approvals and clearances to begin pool construction. Requirements can vary based on your location and site. Experienced pool builders are familiar with the approval process and can guide you through what’s needed.
Is an above ground pool the right fit for you?
Above ground pools are a smart solution when your yard isn’t “pool friendly” — slope, rocky terrain, limited space, hard ground, or design constraints. With the right planning and a secure installation, above-ground pools can be long-lasting, low-maintenance, and look incredible when blended into your landscaping.

Frequently Asked Questions
Can a fibreglass pool be installed above ground?
Yes. Fibreglass pools can be installed fully above ground or partially above ground, depending on site levels and design goals. The key is making sure the installation is engineered with the correct structural support.
What’s the difference between fully above ground and partially above ground pools?
A fully above ground pool sits clearly above natural ground level. A partially above ground pool is set into the ground on one side and raised on the other (common on sloping blocks).
Why would someone choose an above-ground pool instead of in-ground?
Above-ground pools can work better for sloping sites, rocky terrain, hard ground conditions, limited space, or when you want the pool deck to connect at a higher level off the house or patio.
Are above-ground fibreglass pools cheaper than in-ground pools?
They can be, especially if they reduce excavation and backfill requirements — but total cost depends on the site, access, retaining/decking needs, and design complexity.
Do above-ground fibreglass pools need retaining walls or extra support?
In most cases, yes. Above-ground fibreglass installations typically require a retaining/support strategy (and often decking/cladding) to ensure the shell is supported properly and finished safely.
Do you need permits to install an above-ground pool?
Usually, yes. Approvals and clearances vary by area, but most pool builds require compliance around permits and safety barriers. An experienced pool builder can guide you through the process.
