Renovating your home is an exciting opportunity to refresh your space, boost functionality, and add long-term value. But while many homeowners focus on surface-level improvements - new flooring, fresh paint, updated cabinetry - it's often what's behind the walls that truly makes the biggest difference.
If you're planning a renovation, don't overlook the importance of upgrading your plumbing. It's the perfect time to future-proof your home and avoid costly plumbing repairs down the line.
Here are the top plumbing upgrades to consider during a home renovation. As Sunshine Coast Plumbing and Hot Water explains, “Renovation is the ideal time to modernise your plumbing - because what's behind the walls matters just as much as what's in front of them.”
1. Replace Old Pipes
Older homes - especially those built before the 1990s - may still have galvanised steel or copper pipes. These materials are prone to corrosion, blockages, and leaks over time.
If you're opening up walls or replacing floors, it's the ideal moment to upgrade to modern piping materials like PEX or PVC. Not only are these materials more durable, but they're also more resistant to scaling, rust, and temperature changes.
Bonus: You'll likely improve your water pressure and reduce the chance of future plumbing failures.
2. Upgrade to Water-Efficient Fixtures
Swapping out outdated taps, toilets, and showerheads for water-saving alternatives can significantly reduce your water usage - and your utility bills.
Look for fixtures with a high WELS (Water Efficiency Labelling and Standards) rating. Dual-flush toilets, low-flow showerheads, and mixer taps are all worth the investment. Many Australian states also offer rebates or incentives for choosing efficient fixtures, so it pays to check what's available in your area.
3. Consider a Tankless or Solar Hot Water System
Is your hot water system due for an upgrade? If it's more than 10 years old, it may be time to explore a newer, more efficient model.
Tankless (instantaneous) hot water systems take up less space and heat water on demand, saving energy. Alternatively, if you're looking to reduce your carbon footprint and running costs, a solar hot water system with an electric or gas booster could be the way to go.
Upgrading during a renovation allows for easier repositioning of units and pipework if needed.
4. Add or Relocate Plumbing for a Second Bathroom
Renovations are the perfect time to increase your home's liveability - and resale value - by adding an ensuite or second bathroom.
Whether it's a compact powder room under the stairs or a full ensuite extension, planning your plumbing early is key. Consider drainage access, water supply, ventilation, and waterproofing. Working with a licensed plumber from the start will help avoid costly mistakes later.
5. Install a Water Filtration System
Australia's tap water is generally safe to drink, but installing a whole-house water filtration system can take your water quality to the next level. These systems reduce sediment, chlorine, and other impurities, offering cleaner water from every tap.
Since filtration units are typically installed where the water line enters your home, a renovation is the easiest time to make the upgrade.
6. Improve Stormwater and Drainage
Renovations often involve landscaping changes, new roofing, or extended eaves. These can affect how water flows around your property.
It's worth reviewing your stormwater drainage setup to avoid pooling, erosion, or foundation damage. New downpipes, guttering, or stormwater pits may be required. A licensed plumber can assess the current system and recommend any necessary improvements to ensure proper runoff.
7. Future-Proof With Smart Plumbing Tech
If you're already upgrading your home's electrical and lighting, why not do the same for your plumbing?
Smart plumbing technology includes leak detectors, sensor taps, and Wi-Fi-enabled hot water systems. These modern tools help prevent water damage, reduce usage, and allow remote monitoring from your phone.
Some options even notify you of unusual water flow patterns - ideal for early leak detection.
8. Reconfigure Laundry & Kitchen Layouts
Thinking of relocating your laundry or redesigning the kitchen? This is your chance to update ageing pipework, install new appliance connections, or even add a dishwasher or butler's pantry.
Coordinate early with your plumber to ensure all connections are safely and efficiently installed. It'll make the space more practical and reduce the risk of plumbing issues as your household needs grow.
Final Tip: Always Use a Licensed Plumber
It might be tempting to cut costs during a reno, but plumbing is not where you should compromise. Hiring a qualified, licensed plumber ensures the work is safe, up to code, and built to last.
Plus, professional plumbing upgrades often add significant value to your home and can make a huge difference in daily comfort.
