Flat Water Tanks

Flat water tanks are designed for installations where height is restricted but reliable water storage is still required. Their low-profile design makes them ideal for applications where traditional vertical tanks will not fit.

About Flat Water Tanks

Common uses for flat water tanks include:

  • Underslung van tanks
  • Campervan and van conversions
  • Under-floor installations
  • Situations where weight needs to be distributed across a wider surface area
  • Low eaves or single-storey rainwater harvesting systems

Manufactured from durable, UV-stabilised polyethylene, our flat water tanks provide a space-saving solution without compromising on strength or capacity.

We stock a wide range of sizes and orientations to suit different vehicle builds, domestic installations and commercial applications. With 29 models available, you can choose the right capacity and footprint for your project.

If you cannot find the exact dimensions you need, contact our team with your required measurements and we will help you identify the most suitable option.
