ToggleHow to Install a Plunge Pool?
Installing a plunge pool involves several steps, regardless of whether you choose a custom or precast option. Here’s a general overview of the installation process:
1. Choosing Your Pool
Decide between a custom concrete pool or a precast concrete pool.
2. Site Assessment and Preparation
Before any digging begins, a qualified installer will visit your home to inspect the site. This includes checking access for machinery, measuring available space, and reviewing ground conditions.
Once everything is good to go, the real work starts. An excavator is brought in to dig a hole that’s slightly bigger than the pool itself. Why larger? This allows room for leveling and backfilling. After the hole is ready, the base is compacted with around 450mm (about 18 inches) of crushed rock—this forms a strong, stable foundation for your plunge pool.
3. Delivery and Installation
Once your plunge pool is built and ready, it’s time to bring it home. The process differs slightly depending on the type of pool you’ve chosen:
- For custom concrete plunge pools, construction happens directly on-site. This involves building the formwork, pouring the concrete, and allowing it to cure properly before any finishing work begins.
- For precast plunge pools, the unit is delivered fully formed on a flatbed truck. A crane is then used to lift and carefully lower the pool into the prepared excavation site.
4. Plumbing and Pool Equipment Setup
Now that your plunge pool is sitting pretty in the ground, it’s time to bring it to life. Essential components like a filtration system, pump, and sanitation setup are installed. These systems ensure your water stays clean and safe for swimming.
5. Electrical Connections and Final Touches
A licensed electrician will connect all necessary equipment to your home’s power supply. This step is important, as improper wiring can affect how your pool functions—and even void warranties.
6. Landscaping and Enjoying Your Pool
With the pool installed, now comes the fun part—transforming the surrounding space. Whether you go for a timber deck, paving stones, turf, or even a tropical garden theme, your plunge pool becomes the centrepiece of your outdoor haven.
Some homeowners also add fencing (which is usually required by law), shade sails, or lounge seating to create the ultimate backyard retreat.
Custom Pool Installation
Custom plunge pools are designed specifically for your needs and preferences. Here’s how the installation process typically unfolds:

1. Design Phase
During this phase, you work with a builder to create your dream pool’s specifications. You can choose the size, shape, and features like tiles around the pool or additional landscaping elements.
2. Site Preparation
Next, the site must be prepared. This involves excavation to ensure the soil can support the weight of the concrete plunge pools. You might need to clear away any obstacles in your backyard.
3. Construction Process
Once the site is ready, construction begins. This typically involves:
- Pouring concrete to create the shell of your custom pool
- Adding features like steps or benches
- Finishing touches such as tiling around the pool
This method can take several weeks but results in a unique design tailored to your specifications.
Concrete Precast Pool Installation
Precast plunge pools are manufactured off-site and delivered ready to install. Here’s how this process works:
1. Choosing the Pool
Select from various designs available from manufacturers. Precast options often come in standard sizes but may also allow some degree of customisation.
2. Site Assessment and Preparation
Just like with custom pools, you need to assess your site. Ensure that there’s enough space for delivery trucks and cranes to access your property.
3. Delivery and Installation
On delivery day, your precast plunge pool will arrive on a truck. A crane will lift it into place in your backyard—a quick and impressive sight! This entire process usually takes just a few days from delivery to being swim-ready.

Installation Process Comparison
When comparing installation process: custom vs precast plunge pool, there are distinct differences in time, cost, and flexibility.
Aspect | Custom Plunge Pools | Precast Plunge Pools |
---|---|---|
Installation Time | Several weeks | A few days |
Cost | Generally higher | More affordable |
Flexibility | Highly customisable | Limited customisation |
Construction Method | Built on-site | Manufactured off-site |
Cost Considerations
When planning for your new plunge pool, understanding costs is crucial.
Precast Pools
Precast plunge pools are often more affordable than custom options due to their streamlined manufacturing process. The overall cost includes:
- Purchase price
- Delivery fees
- Installation costs
Custom Pools
Custom concrete pools require more investment because of the bespoke design and longer construction time. Costs can include:

Conclusion
Choosing between a custom vs precast plunge pool ultimately depends on your budget, time frame, and personal preferences. If you’re looking for something unique that fits perfectly into your backyard design, then a custom concrete pool might be right for you. However, if you want an affordable option that can be installed quickly with minimal fuss, then consider going with a precast concrete pool.
