Plunge pools and swim spas have become increasingly popular in the Hunter region over the past decade, particularly in areas where full-size pools are impractical due to block size or budget. When it comes time to remove them, the process has similarities to full pool removal but with some meaningful differences in scale, access, and approach. The core difference is size and construction method: most plunge pools are small fibreglass shells, while swim spas are typically a prefabricated unit sitting partly or fully in-ground. Both are removable, often more easily than full-size pools.
This guide covers what’s involved in removing each type, how costs compare, and what to consider when planning the job.
What Is a Plunge Pool?
A plunge pool is a small pool, typically 2-6 metres long and 1.2-2 metres deep, designed for cooling off, hydrotherapy, or compact backyard use. In Newcastle and Lake Macquarie, plunge pools are common in:
- Smaller blocks in inner suburbs like Hamilton, Merewether, Adamstown, and Charlestown
- Courtyard homes where a full-size pool wouldn’t fit
- Properties where the owner wanted a pool but had limited budget or space
Most plunge pools in the region are fibreglass shell units, though some are poured-concrete or modular steel/vinyl liner constructions. The removal method depends on the construction type.
What Is a Swim Spa?
A swim spa is a larger unit, typically 4-8 metres long, that combines the features of a lap pool and a spa. They generate a water current for swimming in place. Most swim spas are prefabricated acrylic or fibreglass units with an integrated shell and equipment cabinet, though some are built in-ground like a pool.
Swim spas can be:
- Above-ground (freestanding): Sitting on a concrete pad with no in-ground excavation
- Semi-inground: Partially recessed into a deck or ground
- Fully inground: Installed in an excavated pit like a pool
The distinction matters significantly for removal, an above-ground swim spa is much simpler to remove than a fully inground one.
Plunge Pool Removal: The Process
For a standard fibreglass plunge pool in the Hunter region:
Step 1: Dewater. Pump or drain the water. Plunge pools hold 10,000-25,000 litres, much less than a full-size pool, so drainage is faster (usually 2-4 hours). Ensure discharge complies with local stormwater rules.
Step 2: Disconnect equipment. Pumps, filters, heaters, and automation for plunge pools are typically mounted in a small cabinet adjacent to the pool. Disconnect electrical (licensed electrician) and plumbing.
Step 3: Extract or break the shell. This depends on access and the shell material:
| Construction Type | Preferred Removal Method | Typical Duration |
|---|---|---|
| Fibreglass (good access) | Crane extraction of whole shell | 3-4 hours |
| Fibreglass (restricted access) | Break into sections, remove pieces | 1-2 days |
| In-ground concrete plunge pool | Hydraulic break-up + excavate | 1-2 days |
| Modular steel/vinyl | Dismantle and remove panels | 4-8 hours |
Step 4: Backfill and compact. The excavation is filled with granular material and compacted in layers. A small plunge pool excavation may require only 10-20 cubic metres of fill.
Step 5: Deregister. If the plunge pool was registered on the NSW Swimming Pools Register (required for pools over 300mm deep that can be accessed by children), deregister after completion. See our deregistration guide.
Swim Spa Removal: The Process
Swim spa removal differs based on whether the unit is above-ground, semi-inground, or fully inground.
Above-ground swim spa: This is the simplest removal in the category. Disconnect plumbing and electrical, drain the unit, then use a crane or telehandler to lift the unit out. Most above-ground swim spas weigh 1,000-3,000 kg empty. The unit is then transported for resale, donation, or disposal. The concrete pad remains (or is broken up separately if removal is wanted). This job typically takes 4-8 hours.
Semi-inground or fully inground swim spa: More complex. The deck or paving around the spa must first be removed or cut back to expose the top of the unit. The unit is then either extracted whole (if crane access allows) or the shell is broken up and removed in sections. For acrylic-surface swim spas, break-up produces acrylic and fibreglass fragments rather than concrete rubble.
Cost Comparison: Plunge Pool vs Full-Size Pool Removal
| Job Type | Typical Cost Range (Hunter 2026) | Notes |
|---|---|---|
| Small fibreglass plunge pool removal | $5,000 to $12,000 | Easier than full-size; depends on access |
| Concrete in-ground plunge pool | $8,000 to $18,000 | Similar process to full concrete pool |
| Above-ground swim spa removal | $1,500 to $4,000 | Crane + disposal; no excavation |
| Semi/fully inground swim spa | $6,000 to $15,000 | Depends on depth and shell type |
For comparison, a full-size fibreglass pool removal in the Hunter region typically costs $12,000 to $22,000, and a concrete pool $18,000 to $32,000. Plunge pool removal is generally cheaper due to the smaller volume of material.
Access Challenges With Small Pool Removal
Plunge pools are often installed in tight courtyards or small backyards precisely because they fit where a full-size pool doesn’t. This can create access challenges for removal equipment, sometimes worse than a larger pool removal, because the pool is in a confined area by design.
For crane lifts of fibreglass shells, the crane needs adequate standing position and clear overhead space. A pool in a courtyard hemmed in by buildings, fences, or overhead wires may require a different approach, breaking the shell by hand with hand tools and removing pieces through gates or by craning sections over the fence.
When requesting a quote, provide:
- Photos of the pool and the access route
- Measurements of gate widths and overhead clearances
- Location of the equipment cabinet relative to the pool
This information lets the contractor plan the method before attending site.
Swim Spa Resale: Is It Worth Trying?
Above-ground swim spas in working condition have meaningful resale value, $5,000 to $20,000 depending on brand, age, and condition. Before committing to disposal, consider:
- Is the spa functional? (Jets, heating, pumps all working)
- How old is it? (Units over 10 years old have limited resale value)
- What brand? (Arcospa, Endless Pools, Michael Phelps brand, Jacuzzi, recognisable brands attract buyers)
- Can you access the unit for buyer inspection before removal?
Listing on Facebook Marketplace or Gumtree in the Hunter/Newcastle region a month before your intended removal date gives buyers time to arrange collection. If a buyer collects the unit themselves (using their own crane or rigging contractor), your removal cost drops to near zero.
Pool Fencing Obligations for Plunge Pools
If your plunge pool is 300mm or more in depth and accessible to children, it is subject to the NSW pool fencing laws and must be registered on the NSW Swimming Pools Register. The same deregistration obligations that apply to full-size pools apply here. See our pool fencing obligations after pool removal guide for what changes once the pool is gone.
When Does a Swim Spa Need Council Approval to Remove?
In most circumstances, removing an above-ground swim spa does not require council approval, it’s exempt development. Removing an inground swim spa follows the same rules as pool removal generally: exempt development in most cases, but check with your council if the structure is in a heritage conservation area or if the excavation is significant. Newcastle City Council and Lake Macquarie City Council websites both have exempt development guides.
How to Handle the Equipment After Removal
Plunge pools and swim spas come with integrated equipment, often in a cabinet attached to the unit or in a nearby equipment box. For swim spas especially, the equipment (pumps, heaters, jet manifolds) is proprietary to the unit and has limited standalone resale value. Most contractors will take the equipment for scrap metal or e-waste disposal as part of the job.
For newer, higher-end equipment in good condition, ask your contractor before it goes to scrap. See our broader guide on what happens to pool equipment when a pool is removed.
Frequently Asked Questions
Does a plunge pool need the same council approvals to remove as a full-size pool? Generally the same rules apply, most plunge pool removals are exempt development in NSW, but check with your local council if you’re in a heritage area or if significant earthworks are involved.
Can I remove my plunge pool myself? For an above-ground fibreglass plunge pool with good access, a determined DIYer can drain and dismantle a small pool. However, electrical disconnection requires a licensed electrician, heavy lifting requires appropriate equipment, and concrete break-up requires suitable machinery. For in-ground pools, professional contractors are strongly recommended.
Is a swim spa registered on the NSW Swimming Pools Register? If the swim spa is capable of holding water to a depth of 300mm or more and a child could access it, yes, it should be registered. Check whether your previous owners registered it and whether deregistration is needed after removal.
How long does it take to remove a plunge pool? For a fibreglass plunge pool with good access, one to two days is typical. A concrete plunge pool may take two to three days. An above-ground swim spa can be lifted out in under a day if access is adequate.
What do I do with the space after a plunge pool is removed? The small footprint of a plunge pool gives you options: paved entertaining area, garden, lawn, or even a garden shed. Because the excavation is smaller than a full-size pool, it compacts faster and can be usable within a few weeks of removal.
