Why a bladder tank

More water, less wasted space

A rigid tank needs a square hole. A Fleximake bladder fills the space you've already got, whether that's a rear footwell, the gap beside a drawer system, or the floor of a boat.

Fits awkward spaces

Box, pillow and cut-out shapes sit low and flat in footwells, under seats, in drawer cavities and in tray tubs, with sizes from 12 to 1000 litres.

Folds flat when empty

Drain it and roll it up. You get your legroom and cargo space back between trips, and you're not carrying the weight of a rigid tank.

Built tough

Reinforced potable PVC or extra heavy-duty TPU with high-frequency welded seams. Water and fuel bladders carry a 2-year manufacturer's warranty.

Measure your space before ordering. Fitment varies between vehicles and model years.

Choosing a material

Heavy-duty PVC or extra heavy-duty TPU?

Most drinking water bladders come in two grades. Both are made for drinking water; the difference is how hard you plan to use them.

Heavy-duty PVC

The everyday choice for touring and camping.

  • 900GSM reinforced potable PVC
  • HF and hot-air welded seams
  • Best value per litre

Extra heavy-duty TPU

Fleximake's toughest option, made for hard touring and rough use.

  • Premium potable TPU
  • Extra resistance to abrasion and punctures
  • Same fits and fittings, tougher skin
Fleximake 40L grey water bladder
Grey water

Grey water bladders

Catch sink and shower water at camp instead of letting it run onto the ground, then empty it at a dump point. When you're done, it folds flat and packs away.

  • 20 L and 40 L sizes
  • Suits caravans, camper trailers, motorhomes and 4WD setups
  • Drain outlet for easy emptying
  • Collapses flat when empty

From $220.00 NZD incl. GST

  • 1200GSM reinforced TPU, rated for diesel, petrol and chemicals
  • Built-in tie-down points to secure the load
  • 2-year manufacturer's warranty

Common questions

Good to know

Is the water safe to drink?

Yes. Fleximake drinking water bladders are made from potable PVC or TPU to the AS/NZS 4020 standard for materials in contact with drinking water. The water can taste slightly different at first, so give a new bladder a rinse before the first fill.

How do I know which one will fit?

Every product page lists the bladder's dimensions. Measure the space you want to use, and allow for the bladder rounding out as it fills. If you're unsure, send us your measurements and vehicle and we'll help.

Can I get a custom size or shape?

Yes. Dimensions, shape, fittings and fitting positions can be made to order. Custom work costs more than standard sizes, so get in touch for a quote.

Can I use a water bladder for fuel, or a fuel bladder for water?

No. Water bladders are made from potable materials for drinking water. Fuel bladders are made from fuel-resistant TPU for diesel, petrol and chemicals. Keep each one for its intended use. For jet fuel or other specialty fuels, contact us first.

What warranty do they have?

Standard Fleximake water and fuel bladders carry a 2-year manufacturer's warranty. Claims in New Zealand are handled through TowPro.
