8K - 10K Litre Slimline 304 Grade Stainless Water Tank

Slimline tanks are a great alternative when you have space constraints or want to hide the tanks away. Typically used for residential applications, they can be ideal to utilise a wasted space to store valuable water coming free off your roof.

Many builders also use these tanks to meet the NSW BASIX requirements where the water is fed to the washing machine and toilets. See our BASIX packages for more info.

You can select your slimline tank measurements using our Size-a-tank feature to get just the right fit.

Slimline tanks range from 800 litres up to 10,000 Litres and range in price from $800 up to $4600. More expensive than the equivalent round tank of the same capacity, but it is a good solution if nothing else fits.

Our slimline tanks are available in an elegant stainless steel look or we can colour coat to any colourbond colour.
