Fleximake 40L Grey Water Bladder

More Capacity. Same Smart Design. Built for Longer Adventures.

When a weekend away turns into weeks on the road, you need a grey water solution that keeps up. The Fleximake Grey Water Bladder 40L is an Australian-made, foldable waste water tank built for caravanners, camper trailer owners and extended 4WD tourers who need a bit more capacity without the bulk of a rigid tank.

More and more campsites, national parks, caravan parks and rest areas across Australia now require travellers to arrive with a self-contained grey water solution. The 40L bladder gives you the capacity to go longer between dump runs while keeping your setup fully compliant.

🏕️ More Capacity for the Long Haul

The 40L bladder is the go-to choice for families, couples on extended trips, or anyone running a larger setup. Like its 20L sibling, it folds completely flat when empty for easy storage in tight spaces. The integrated lifting straps mean you can carry a full bladder comfortably and safely to the disposal point without awkward manoeuvring.
