The Block Head’s take
The tank was introduced as being made of BlueScope Aquaplate steel, durable and Australian made, which is three of the four things a tank is supposed to be. The contestant then guessed the colour on the first try, having studied the Colorbond chart.
It is the only product on the show whose buyer prepared for the colour decision in advance.

If you are thinking of buying
- Check local rules on rainwater tanks and whether it can be plumbed into the house.
- Match the colour to your roof and fence, since Colorbond colours are consistent across products.
- Ask about delivery to the tank base, which is not always included.
