The right pool for you is the one that fits your block, your budget and the way your household will actually use it. Decide on the purpose first (play, laps, relaxing or entertaining), then match it to a construction type (concrete, fibreglass or vinyl-lined), and finally budget for the extras and running costs owners often forget, such as fencing, heating and power.
This guide walks through each decision in order, with a focus on Sydney and New South Wales, where the rules described below apply. If you live elsewhere, the planning steps are the same, but check approvals and safety law with your local council.
Quick summary
- Measure your usable space and check access for machinery before you fall for a design.
- Choose a licensed builder who knows local council requirements and NSW pool safety law.
- Compare concrete, fibreglass and vinyl-lined pools on cost, build time, flexibility and upkeep.
- Budget for fencing, landscaping, heating and ongoing running costs, not just the shell.
- Plan the maintenance routine before you build, because equipment choices shape it.
Step 1: assess your space and how you will use the pool
Start with a tape measure and a plan of your garden. Mark boundaries, the house, trees, the sewer and stormwater lines, and any easements. Then work out how much space is left once you allow for a safety fence, paving around the pool and somewhere to put the filtration equipment, ideally out of earshot of bedrooms, both yours and the neighbours’.
Look at sun and shade across the day as well. A pool in full afternoon sun warms faster and needs less heating, while one under large trees will collect leaves and stay cooler. Overhanging branches also add to cleaning time, so factor that in before choosing a spot.
Match the pool to its purpose
- Family play: a wider shape with a generous shallow end, a bench or wide entry steps, and room on the paving for supervision.
- Fitness: a lap pool, long and narrow, ideally at least 10 to 15 metres if you want to swim proper lengths. A shorter pool with a swim jet can work in tight spaces.
- Relaxing and cooling off: a plunge pool, typically only a few metres long, which suits small or inner-city blocks and uses less water and chemicals.
- Entertaining and views: a larger pool with features such as a spa, ledges, lighting or an infinity edge on a sloping block with an outlook.
Think ten years ahead. Young children grow into teenagers who want to swim laps or have friends over, and a pool is very hard to resize once it is in the ground. If you might sell within a few years, a clean, practical design with good surrounding space generally appeals to more buyers than a highly personal one.
Check site access early
Access matters more than many people expect. Fibreglass shells arrive in one piece and usually need crane or truck access, while concrete can be built on sites where only smaller machinery can get in. Steep driveways, narrow side passages, overhead power lines and neighbouring structures can all change the method and the price.
Step 2: choose the right professional
The builder you pick affects everything from approvals to how long the finish lasts. Working with an experienced pool builder in Sydney gives you local knowledge of council rules, Sydney’s clay and sandstone soils, and the best time of year to dig. In NSW, residential pool building work over the Fair Trading threshold must be done by a licensed contractor, with a written contract and home building compensation cover, so check the licence on the NSW Fair Trading online register before you sign.
Questions to ask every builder you shortlist
- Can I see recent pools you have built and speak to those owners?
- Does the quote include excavation, rock removal, fencing, electrical, plumbing and landscaping, or are those extras?
- Who handles council approval or complying development certification?
- What warranties apply to the structure, the interior finish and the equipment?
- What is the realistic timeline, and what happens if you hit rock or groundwater?
- How are progress payments staged, and what triggers each one?
A good builder listens to your ideas, explains trade-offs plainly, and gives you a clear, itemised quote and project plan so you know what to expect at each stage. Be wary of anyone who pushes for a large deposit before approvals are in place or who is vague about what the price includes.
Step 3: compare pool materials and types
The three main construction types each suit different priorities. The table below gives a like-for-like comparison.
| Factor | Concrete | Fibreglass | Vinyl-lined |
|---|---|---|---|
| Shape and size | Almost any shape or depth | Limited to manufacturer moulds | Flexible, within kit limits |
| Typical build time | Longest, often several weeks to a few months | Fastest once the hole is dug | Moderate |
| Relative upfront cost | Usually highest | Mid-range | Often lowest |
| Surface | Tiles, pebble or render | Smooth gelcoat | Soft vinyl liner |
| Algae resistance | Lower, porous finishes need more attention | High, smooth surface | Good |
| Long-term upkeep | Periodic resurfacing | Low, occasional gelcoat care | Liner replacement every several years |
| Best for | Custom designs, tricky or sloping sites | Families wanting low maintenance and a quick build | Tighter budgets |
Concrete pools
Concrete (sprayed concrete or shotcrete) is the choice for custom shapes, infinity edges, integrated spas and awkward sites. It is very durable, but the build takes longer and the interior finish will eventually need renewing. Pebble finishes tend to last longer than painted or rendered finishes, and fully tiled interiors are the premium option.
Fibreglass pools
Fibreglass shells are made in a factory and dropped into place, so once excavation is done, installation is quick. The smooth surface resists algae and is gentle on feet, which suits families. The trade-off is less design freedom, a fixed range of sizes, and the need for good site access for delivery.
Vinyl-lined pools
Vinyl-lined pools use a supporting wall and a replaceable liner. They are less common in Australia than concrete and fibreglass, but can be cheaper upfront. Liners can be punctured by sharp toys or pet claws and fade in strong sun, so budget for replacement during the pool’s life.
Pool styles
- Plunge pools: compact, lower running costs, great for small courtyards.
- Lap pools: long and narrow for fitness, and they can run along a side boundary.
- Infinity pools: suit sloping blocks with views, but need more engineering and a catch basin, which adds cost.
- Pool and spa combinations: a heated spa attached to the pool extends the season considerably.
Step 4: rules and approvals in NSW
Pool safety is tightly regulated in New South Wales under the Swimming Pools Act 1992 and its regulation. The main points for new owners:
- Approval: depending on the site and design, your pool may qualify as complying development through a private certifier or may need a development application to council. Your builder or certifier should confirm which applies.
- Fencing: a compliant child-resistant barrier with self-closing, self-latching gates is required, built to the Australian Standard referenced in the regulation.
- Registration: pools and spas must be registered on the NSW Swimming Pool Register.
- CPR sign: an approved resuscitation sign must be displayed near the pool.
- Selling or leasing: you will generally need a certificate of compliance or occupation certificate for the pool.
Fencing rules are where many owners trip up after handover. Pot plants, barbecues or furniture placed near the fence can create climbable footholds, and gates propped open defeat the point of the barrier. Rules differ in other states, so check with your local council if you are outside NSW, and speak to a certifier if you are unsure whether your design complies.
Step 5: budget for the whole project
Pool prices vary enormously with size, access, soil, finishes and features, so the only reliable figure is an itemised quote for your site. Get at least three and compare them line by line rather than on the headline total.
Installation costs
- Excavation and spoil removal, plus rock breaking if you hit sandstone.
- Engineering, approvals and certification fees.
- Fencing and gates, paving or decking, and landscaping.
- Electrical work, lighting and plumbing connections.
Running costs
Ongoing costs come from electricity for the pump, chemicals or salt, water top-ups, cleaning and repairs. A variable-speed pump usually uses far less power than an older single-speed pump. Heating makes the biggest difference to the swimming season but also to bills, so compare options carefully. Solar heating has low running costs in a sunny climate, while heat pumps work in more conditions. Investing in energy-efficient equipment, such as solar heaters or Pool heaters, can help reduce long-term operating costs, especially when combined with a good cover to hold the heat in overnight.
| Heating option | Running cost | Works best when | Watch out for |
|---|---|---|---|
| Solar | Low | Plenty of roof space and sun | Less effective on cloudy or cool days |
| Heat pump | Moderate | You want reliable heat over a longer season | Upfront cost and some running noise |
| Gas | Higher | You want fast heating on demand, such as for a spa | Ongoing fuel cost |
| Pool cover alone | Very low | Any pool, to retain heat and cut evaporation | Needs to be taken on and off |
Hidden costs to watch for
- Unexpected rock, poor soil or groundwater during excavation.
- Covers, cleaners and safety accessories bought after handover.
- Resurfacing, liner replacement and equipment replacement over the pool’s life.
- Possible increases in home insurance and council rates.
A sensible approach is to hold back a contingency for surprises during excavation, rather than committing every pound or dollar of budget to finishes. If the contingency is not needed, it can go towards landscaping once the pool is complete.
Step 6: plan for maintenance and longevity
A pool that is easy to look after gets used more. A simple routine keeps water clear and safe:
- Several times a week in summer: skim leaves, empty the skimmer basket and check the water level.
- Weekly: test and adjust pH and chlorine, brush walls and run a cleaner or vacuum.
- Monthly: clean or backwash the filter as the manufacturer recommends and check equipment for leaks.
- Yearly: have the pool and equipment serviced, and inspect the fence and gate latches.
Saltwater chlorinators are popular because they generate chlorine automatically and many owners find the water gentler on skin and eyes. Automatic cleaners and a well-fitted cover reduce debris, evaporation and heat loss. Water use matters in a dry climate too; our guide to sustainable garden watering has ideas for keeping the landscaping around your pool green without waste.
Common mistakes new owners make
- Choosing a pool that fills the garden and leaves no room for shade or seating.
- Placing the pump next to a bedroom window.
- Skipping a cover to save money, then paying more in heating and chemicals.
- Letting chemical levels drift, which leads to cloudy water and stained surfaces.

Frequently asked questions
Which pool type needs the least maintenance?
Fibreglass pools are generally the lowest maintenance because their smooth gelcoat surface resists algae. They also do not need periodic resurfacing in the way concrete finishes do.
How long does it take to build a pool?
It depends on type, approvals and site conditions. Fibreglass is usually quickest once approved, while concrete pools commonly take several weeks to a few months.
Do I need council approval for a pool in NSW?
Most new pools need either complying development certification or a development application. Your pool must also meet fencing rules and be listed on the NSW Swimming Pool Register.
What size pool do I need for swimming laps?
For proper laps, aim for at least 10 to 15 metres in length. If space is tight, a shorter pool with a swim jet is a practical alternative.
Is pool heating worth it?
For many owners, yes, because heating extends the swimming season. Solar heating has low running costs, heat pumps work in more conditions, and a pool cover helps either option.
Bottom line on choosing a pool
Start with how you will use the pool, measure the space and access honestly, and get three itemised quotes from licensed builders. Choose fibreglass for a quick, low-maintenance family pool, concrete for a custom design, and budget for fencing, heating and a cover from day one.
