An infinity-edge (vanishing-edge) or raised pool is one of the more involved jobs on the books, not because the pool itself is unusual to demolish, but because of what’s built around it. These pools are almost always sited on sloping or view-oriented blocks, purpose-built to sit above the natural ground level or spill visually toward a view, which means the structure holding them up is frequently doing real retaining work. Remove that structure carelessly and you’re not just taking out a pool, you’re potentially destabilising the terrace, deck or garden bed below it.
This guide sets out what makes infinity-edge and raised pool removal different from a standard in-ground job, what drives the cost up, and what to check before getting quotes. Every figure here is an indicative, region-wide guide from our pool removal cost by pool type guide, not a fixed price; the exact scope and number always follow a free site inspection.
What Makes an Infinity-Edge or Raised Pool Different to Demolish
A standard in-ground pool sits below or at ground level, surrounded by soil on every side, and the demolition sequence is straightforward: break the shell, cart the rubble, backfill the void. An infinity-edge or raised pool changes that picture in a few specific ways:
- A vanishing edge wall. The signature “disappearing” edge of an infinity pool is a lowered section of wall with a catch basin or weir behind it, collecting the water that spills over. That catch basin is itself a smaller concrete structure tied into the main shell, and it has to be broken out and accounted for separately from the main pool body.
- Retaining structure. Raised and infinity-edge pools on sloping blocks are frequently built with at least one wall doing double duty as a retaining wall for the terrace, deck or garden above or beside it. On some builds the entire downhill wall of the pool is the retaining structure for everything uphill of it.
- Elevated construction. Where the pool sits above natural ground level rather than in it, there’s often a substantial engineered base or podium beneath the shell, itself sometimes suspended over a void or a lower-level structure such as a garage or storage room.
- Plant room and plumbing runs. Infinity-edge systems need a balance tank, additional pump capacity and pipework running from the catch basin back to plant, all of which needs disconnecting and, in most cases, removing as part of the job.
None of this is exotic engineering by trade standards, but it does mean the removal sequence has to be planned by someone who understands what’s structural and what’s cosmetic before the first breaker touches the shell.
Why the Retaining Function Changes the Price and the Process
The single biggest cost and risk driver on these jobs is confirming what happens to the slope once the pool’s retaining wall is gone. If a wall was genuinely retaining the ground or a structure behind it, that function has to be replaced, either with a new engineered retaining wall built as part of the same job, or with a re-graded, engineered slope that no longer needs a wall at all. Skipping this step and simply smashing out a retaining wall on a sloping block is how a straightforward pool removal turns into a shifted terrace, a cracked driveway, or worse, months later.
In practice this means an infinity-edge or raised pool removal on a genuinely sloping or view block should involve, at minimum, a geotechnical or structural assessment of what the wall is doing before demolition starts, and often an engineer’s design for whatever replaces it. That assessment and design work sits on top of the demolition and backfill costs that apply to any concrete pool removal, which is the main reason these jobs land at the higher end of the region’s overall concrete pricing.
Indicative Cost for Infinity-Edge and Raised Pool Removal
These figures build on the standard concrete pool removal ranges set out in our pool removal cost by pool type guide, with an allowance for the additional structural and access complexity typical of infinity-edge and raised builds.
| Scenario | Indicative range | Notes |
|---|---|---|
| Standard concrete pool, full removal, reasonable access | $12,000-$25,000+ | Baseline concrete range, no retaining or elevation involved |
| Infinity-edge or raised pool, non-retaining wall, reasonable access | $18,000-$28,000+ | Extra catch basin, balance tank and plant removal |
| Infinity-edge or raised pool, genuine retaining function, engineering required | $25,000-$45,000+ | Includes engineering assessment and design of replacement retaining or re-graded slope |
| New engineered retaining wall to replace removed structure | Quoted per site by a structural engineer and contractor | Scope varies enormously with wall height and load |
These are indicative, region-general figures, not a quote. The real number depends entirely on how much of the pool’s structure is genuinely load-bearing, how steep the site is, and what machine access is available, all of which are confirmed at a free site inspection.
What a Proper Quote Should Include
Because these are higher-stakes jobs than a standard in-ground pool, a proper quote and process should cover:
- A structural or geotechnical assessment of what any pool wall is retaining, before any demolition sequence is finalised.
- Demolition staged to protect what’s uphill or adjacent, rather than breaking the whole structure out in one pass.
- Removal or capping of the catch basin, balance tank and associated plumbing, separate from the main pool shell.
- A clear plan for what replaces the retaining function, whether that’s a new engineered wall or a re-graded, stabilised slope.
- Backfill and compaction matched to the site’s slope and drainage, the same discipline that applies to every pool removal but with extra attention to water management on a sloping block. Our excavation and backfill page covers what that process should look like.
- Standard inclusions: draining, licensed electrical disconnection, asbestos assessment of older surrounds, and NSW Swimming Pool Register deregistration once the job’s done.
Is Full Removal or Partial Fill-In an Option?
Full removal is almost always the safer and more common approach for infinity-edge and raised pools, precisely because a partial fill-in leaves a structure in the ground whose retaining function is now unmonitored and unmaintained. Where a genuine retaining wall is part of the pool, leaving it buried and untested under load is a bigger long-term risk than it would be for a straightforward flat-block pool with no structural role. If a fill-in is being considered on one of these sites, it needs an engineer’s sign-off on the retaining question just as much as a full removal would.
Infinity-Edge and Raised Pool Removal: FAQs
Why does infinity-edge pool removal cost so much more than a standard concrete pool? The extra cost comes from the catch basin and balance tank system, the retaining or structural function many of these pools serve on sloping blocks, and the engineering assessment needed before demolition can proceed safely. A standard flat-block concrete pool doesn’t carry any of these extra scope items.
Does every raised or elevated pool need an engineer before removal? Not necessarily, but any pool wall that appears to be holding back soil, a terrace, a deck or a structure above or beside it should be assessed before demolition starts. This is determined at the site inspection, not assumed from the pool’s style.
Can the retaining wall just be left in place and the pool removed around it? Sometimes, if an engineer confirms the wall functions independently of the pool shell and can be safely retained on its own. This is a case-by-case structural question, not a standard part of the removal process.
Does this apply to raised above-ground-style pools too, or only true infinity-edge builds? It applies to any pool, infinity-edge or simply raised, where the structure is elevated above natural ground level or built into a slope such that a wall is doing more than just holding water. The vanishing edge itself is one specific version of this broader retaining-and-elevation problem.
How long does an infinity-edge or raised pool removal take? Longer than a standard concrete pool removal, commonly a week or more once engineering assessment, staged demolition and any replacement retaining work are factored in. Timing is confirmed at inspection once the scope of retaining work is understood.
