Undertray Water Tanks
Undertray Water Tanks: A Smart Solution for Off-Road Adventures
Are you tired of juggling water storage while exploring the outback? Do you need a reliable, space-saving way to carry fresh water on your 4WD trips? Undertray water tanks offer a practical and durable solution, keeping your water secure without taking up valuable cargo space.
Built tough for Australian conditions, these tanks are designed to fit neatly under your vehicle, giving you easy access to clean water wherever your adventures take you. Let’s explore why undertray water tanks are a must-have for off-road enthusiasts.
Why Choose an Undertray Water Tank?
Undertray water tanks are a game-changer for 4WD and camping setups. Unlike traditional water containers that clutter your vehicle, these tanks mount discreetly beneath your chassis, freeing up room for gear and supplies.
The BOAB Poly Water Tanks, distributed by Canyon Off-Road, are a standout option. Made from tough, BPA-free polyethylene, they ensure safe water storage without the risk of contamination. Their ‘drop-in’ installation makes them compatible with a wide range of vehicles, from utes to trailers.
These tanks are built to last, with reinforced construction that withstands rough terrain and extreme temperatures. Whether you’re crossing the Simpson Desert or setting up camp in the High Country, you can trust your water supply to stay secure.
With multiple outlet options, including 1/2" BSP fittings, you can easily connect taps or plumbing systems for hassle-free water access. The 1.5" BSP threaded filler makes refilling quick, while the optional breather line prevents airlocks during fast fills.

Versatile and Convenient Water Storage
One of the biggest advantages of undertray water tanks is their versatility. They come in various sizes and capacities, so you can choose the perfect fit for your vehicle and travel needs.
The BOAB tanks, for example, measure 1070mm in length, 805mm in width, and just 115mm in height, making them slim enough to tuck under most 4WDs. At only 11kg when empty, they won’t add unnecessary weight to your rig.
These tanks aren’t just for underbody mounting—they can also be installed in footwells, luggage areas, or even on roof racks if needed. This flexibility means you can optimise your vehicle’s space without sacrificing water capacity.
For long trips, having a reliable water source is crucial. Undertray tanks let you carry enough water for Drinking, Cooking, Washing
so you can stay self-sufficient in remote areas. No more relying on questionable water sources or running out mid-journey.
If you’re serious about off-road adventures, an undertray water tank is a smart investment. Check out Canyon Off-Road’s range of 4x4 accessories to find the perfect tank for your setup. With durable construction, easy installation, and practical features, it’s the ultimate upgrade for any overlanding rig.
