About Rain Tanks Australia

With over 30 years in the rainwater tank industry, we know what works and what lasts. We’ve helped thousands of homeowners, builders, and businesses find the right tank solution for their property – and we’re still just as passionate about it today.

We specialise in compact, modular 1,000 litre slimline tanks that solve a problem traditional tanks can’t: fitting serious water storage into tight spaces. At just $350 each with all joining fittings included, our tanks make it easy and affordable to start harvesting rainwater or expand your existing setup without the hassle.

Every tank we sell is brand new with a manufacturer’s warranty, and we keep plenty of stock on hand so you’re not waiting around. Whether you’re picking up from our Lake Haven location on the Central Coast or the factory in St Marys, we’ll make sure you leave with exactly what you need.

We’re not a faceless warehouse. When you call, you’ll speak directly to us, who’ll walk you through sizing, configuration, colours, and anything else. No scripts, no runaround – just straight answers from someone who’s done this for three decades.
