Why Autumn is the Perfect Time to Install a Plunge Pool

As the weather cools down, many homeowners assume pool season is coming to an end—but autumn is actually the perfect time to install a plunge pool. Not only do you avoid the peak summer rush for installations, but pairing your Aussie Plunge Pool with a heater ensures year-round relaxation, no matter the season.

If you’re considering a DIY plunge pool installation, this guide will take you through everything you need to know—from preparing your site to final installation and maintenance.

DIY Plunge Pool Installation

1. Pre-Installation: Planning & Council Approvals

Before you begin installing your Aussie Plunge Pool, make sure you’ve completed these essential steps:

✅ Check Local Council Requirements – Pool regulations vary by area. Most councils require:

Pool fencing that meets Australian safety standards.
A pool registration with local authorities.
Correct backwash drainage setup (to sewer or stormwater, depending on council rules).
CPR & safety signage.

✅ Choose the Right Location – Your plunge pool should be placed on stable, level ground away from large trees to reduce debris buildup.

✅ Gather Tools & Materials – You’ll need:

– Excavation tools (if installing inground).
– Crusher dust or sand base material (for stability).
– A pool pump & filtration system.
– Plumbing connectors & hoses.

✅ Dial Before You Dig – Call 1100 to ensure no underground pipes or cables interfere with installation (this is a free service) OR visit https://www.byda.com.au/contact/

2. Site Preparation & Pool Placement

Step 1: Preparing the Base

A stable, level base is critical for a successful installation.

1. Mark out the installation area ensuring at least 150mm extra space around the pool.
2. Excavate the ground (if required) to create a firm, even surface.
3. Lay a 100mm compacted crusher dust or sand base to support the pool’s weight.
4. Check for level using a spirit level—an uneven base can cause future structural issues.

Step 2: Positioning the Pool

1. Arrange safe delivery—your Aussie Plunge Pool shell will arrive pre-formed.
2. Carefully lower the pool onto the prepared base using lifting equipment (if needed).
3. Check alignment and levelling—the pool should sit flush on the surface.

Step 3: Backfilling (For Inground Installations)

If installing inground, fill the pool with water first before backfilling to allow for natural flex. Use crusher dust or sand to backfill, compacting gently to avoid unnecessary pressure on the walls.

3. Plumbing & Filtration System Setup

Your Aussie Plunge Pool comes pre-cut with a skimmer box and return line nozzle for easy installation.

Step 1: Install the Skimmer Box & Return Fitting

• The skimmer box hole is pre-cut at the factory.
• Affix the skimmer box following the manufacturer’s manual.
• Attach the return fitting using the provided threaded adaptor.

Step 2: Set Up the Pool Pump & Sand Filter

• Use 15kg of Quartz sand (0.4 – 0.8mm grain size) for filtration.
• Connect hoses as per the instruction manual, ensuring they are clear of debris before use.
• Test all connections for leaks before turning on the system.

  Pro Tip: Running the filter system daily will help maintain crystal-clear water year-round.

4. Filling & Balancing the Water

Once plumbing is complete, it’s time to fill your plunge pool!

Step 1: Fill with Water

• Use a garden hose or arrange bulk water delivery if needed.
• As the water level rises, check for leaks around fittings and hoses.

Step 2: Treat the Water

• Add pool chlorine or mineral salts to prevent bacteria growth.
• Use a test kit to check pH, alkalinity, and chlorine levels.
• Adjust chemical levels as needed for safe swimming conditions.

Pro Tip: If your area was affected by heavy rains or flooding, ensure your fill water is clean and free from contaminants.

5. Post-Installation: Safety & Enjoyment

✔️ Install Pool Fencing

• Ensure fencing meets Australian safety regulations.
• Install childproof gate latches to prevent unauthorised access.
• Mount a CPR safety sign on the fence as required by law.

✔️ Consider Heating for Year-Round Comfort

Autumn is the perfect time to install a plunge pool heater. Options include:

• Electric heat pumps – Energy-efficient & cost-effective.
• Solar pool heating – Utilises free energy from the sun.
• Gas heaters – Ideal for rapid heating in colder climates.
  Pro Tip : By installing a heater now, you can enjoy your Aussie Plunge Pool throughout winter.

✔️ Regular Maintenance

• Test & balance water weekly to keep it safe.
• Clean filters & skimmers to prevent clogging.
• Check fittings & pipes regularly for wear or leaks.
