Owning a pool in Sydney is a quintessential part of the Australian dream. But like any part of a home, pools eventually need a little TLC. Whether your pool is looking tired, the tiles are cracking, or the equipment just isn't efficient anymore, a renovation can breathe new life into your backyard oasis.
The big question on every homeowner's mind is always: what’s the damage to the wallet?
Budgeting for a renovation isn't straightforward because every pool is different. This guide breaks down the costs you can expect in 2025, the factors that will drive your price up or down, and how to plan your budget effectively.
Why Renovate Your Pool Now?
Before we talk numbers, it's worth understanding why Sydney homeowners are choosing to renovate in 2025. Aside from aesthetics, modernizing a pool adds significant value to your property.
Maybe you bought a house with an existing pool that’s stuck in the 90s, or perhaps your current setup is leaking money through inefficient pumps and evaporation. A renovation fixes structural issues, improves safety, and upgrades energy efficiency, saving you money on running costs in the long term.
The Average Cost of Pool Renovation in Sydney
In 2025, the cost of renovating a pool in Sydney varies wildly depending on the scope of work. You can spend as little as $3,000 for minor repairs or upwards of $50,000 for a complete transformation.
Here is a general breakdown of price ranges to help you get your bearings:
- Basic Refresh ($3,000 – $10,000): This usually includes acid washing, minor tile repairs, or replacing a pump or filter. It’s about maintenance rather than a visual overhaul.
- Cosmetic Upgrade ($10,000 – $25,000): This range covers resurfacing (pebblecrete or fiberglass), new waterline tiles, and perhaps upgrading to LED lighting.
- Major Overhaul ($25,000 – $60,000+): At this level, you are looking at changing the pool shape, adding a spa, extensive structural repairs, high-end tiling (like glass mosaics), and complete landscaping integration.

Key Factors That Influence Your Quote
Why does your neighbor’s renovation cost $15,000 while yours is quoted at $35,000? Several variables play a huge role in the final price tag.
1. Pool Size and Depth
It’s simple math: bigger pools require more materials and more labor. Resurfacing a 10m pool takes significantly longer and uses more product than a 6m plunge pool. If your pool is exceptionally deep, scaffolding or specialized equipment might be needed to reach the bottom safely.
2. Surface Material Choice
What you choose to line your pool with is one of the biggest cost drivers.
- Paint: The cheapest option upfront but needs re-doing every few years.
- Pebblecrete: A popular, durable mid-range option common in Sydney.
- Fully Tiled: The premium choice. Glass mosaic tiles look stunning and last a lifetime, but the labor and material costs are high.
3. Structural Repairs
If your renovation is purely cosmetic, it will be cheaper. However, if your renovator discovers concrete cancer (rusting steel reinforcement), major cracks, or plumbing leaks, these must be fixed before any aesthetic work begins. Ignoring structural issues is a recipe for disaster later on.
4. Equipment Upgrades
Are you sticking with your old pump? Many renovations in 2025 include upgrading to variable-speed pumps, saltwater chlorinators, or smart automation systems. While these add to the upfront cost, they reduce electricity usage significantly.
5. Access to the Site
Sydney properties can be tricky. If you live on a steep block in the Northern Beaches or have a terrace in the Inner West with no side access, costs will rise. If machinery cannot be brought in easily, manual excavation and material transport will increase labor hours.

Specific Renovation Tasks and Their Price Tags
To help you build your budget, here are estimates for specific jobs commonly requested during a renovation.
Resurfacing
Resurfacing is the most common renovation task. Over time, surfaces become rough or stained.
- Pebblecrete: $8,000 – $15,000 depending on the bead quality.
- Fiberglass: $10,000 – $18,000 for a smooth, durable finish.
- Vinyl Liner Replacement: $4,000 – $8,000.
Retiling
Replacing the waterline tiles can instantly modernize a pool.
- Ceramic Tiles: $40 – $70 per linear meter (plus labor).
- Glass Mosaic Tiles: $80 – $150+ per linear meter (plus labor).
Adding Heating
Extending your swimming season is a great investment.
- Solar Heating: $3,000 – $6,000.
- Electric Heat Pump: $4,000 – $8,000.
- Gas Heating: $5,000 – $9,000 (plus gas line installation).
Lighting
Replacing old halogen lights with modern LEDs changes the mood of your backyard instantly.
- LED Light Replacement: $400 – $900 per light.
Budgeting Tips for Your Renovation
Renovations have a habit of expanding once they start. Here is how to keep your finances under control.
1. Define Your "Must-Haves" vs. "Nice-to-Haves"
Do you need a heater right now, or can that wait? Focus on structural integrity and the pool interior first. You can always add automation or new furniture later.
2. Add a Contingency Fund
Always set aside 10-15% of your total budget for unexpected surprises. Once the water is drained and the old surface is stripped back, hidden issues like rust or cracks often reveal themselves.
3. Get Multiple Quotes
Don't settle for the first price you see. Get at least three quotes from reputable Sydney pool builders. Ensure they are comparing apples with apples—check that they are quoting for the same materials and scope of work.
4. Use a Calculator
Guesswork is dangerous when budgeting. Using a tool can help you get a realistic baseline before you start calling contractors. Try this pool cost calculator Australia to crunch the numbers.
Choosing the Right Contractor in Sydney
The pool industry is busy, and finding the right tradie is crucial. Look for builders who are members of SPASA (Swimming Pool & Spa Association). This ensures they adhere to industry standards and have the necessary insurance.
Ask for references and look at their previous work. A cheap quote often means corners are being cut, usually in surface preparation or waterproofing, which will cost you double to fix in a few years.
Conclusion
Renovating your pool is a significant investment, but one that pays dividends in lifestyle and property value. In 2025, Sydney homeowners have more options than ever to create a resort-style experience at home. Whether you are doing a quick resurface or a total backyard transformation, understanding the costs upfront allows you to plan with confidence.
