Not every home improvement is about paint and tiles. Some of the most worthwhile upgrades are plumbing ones that improve water efficiency, reliability and everyday comfort — often for less than the cost of a cosmetic renovation. Here are seven practical plumbing upgrades worth considering for your Gold Coast home.
1. Replace an old single-flush toilet with a dual-flush suite
Older single-flush toilets can use up to 11 litres per flush. A modern dual-flush toilet with a 4-star WELS rating uses around 4.5 litres for a full flush and 3 litres for a half flush. For a family, the water savings are significant over a year. See our guide on whether to repair or replace your toilet.
2. Install water-efficient showerheads
Showers are one of the largest indoor water uses in most homes. A water-efficient showerhead with a high WELS rating can reduce water use per shower by 30–50% without noticeably affecting pressure. The savings show up on both your water and energy bills (less hot water to heat).
3. Upgrade to a tempering valve (or a modern mixer)
Older homes may have hot water delivered at tank temperature, with cold water mixed at the tap. A tempering valve delivers a safe, controlled temperature at the outlet, reducing scalding risk and improving comfort. If your hot water is too hot or not consistent, a tempering valve upgrade may be the fix. See our hot water services
4. Install a rainwater tank for garden irrigation
A rainwater tank connected to your roof can supply garden irrigation and, with the right plumbing, toilet flushing and laundry. On the Gold Coast, where summer storms deliver plenty of rain, a tank can significantly reduce mains water use. See our guide on the benefits of installing a rainwater tank
5. Replace old galvanised supply pipes
Older Gold Coast homes may still have galvanised iron supply pipes that rust internally, reducing pressure and discolouring the water. Replacing them with copper or approved plastic pipe restores pressure and water quality, and removes a common source of burst pipes. If your water pressure has dropped or the water is discoloured, a pipe assessment is worthwhile.
6. Add a water filter
An under-sink or whole-house water filter improves taste and reduces chlorine and sediment. Under-sink systems are relatively simple to install and maintain; whole-house systems require more plumbing but treat all water entering the home. See our guide on water filter installation
7. Upgrade your hot water system
If your hot water system is old, undersized or inefficient, upgrading to a modern system — whether continuous flow, heat pump, or a correctly sized storage system — can improve reliability, reduce running costs and ensure you don't run out during the morning shower rush. See our guide on hot water system sizing
Which upgrade is right for you?
The best upgrade depends on your home's current plumbing, your water usage and your budget. A plumber can assess what's most worthwhile for your situation. If you're considering any of these upgrades, contact our Gold Coast team for advice and installation.
