Are you looking for a new grey water tank?
This isn’t the most glamorous caravan accessory, but it’s a very useful one. If you plan on travelling to Australian National Parks, then a grey water tank may actually be a legal necessity.
It’s not mandatory to have a caravan grey water tank at regular campsites, but it’s advisable. Environmentally responsible campers dispose of their grey water in a considerate manner - rather than just dumping it on the ground.
But where do you start? There are so many products on the market it can be confusing.
Let’s look at a variety of greywater tanks for caravans from different manufacturers and break them down to figure out the best option for you.

Best Caravan Grey Water Tanks
50L Universal Water / Grey Water Tank
Best Value
One of the most affordable portable grey water tanks for caravans, the Universal costs between $50 and $90, with a one-year warranty.
This caravan water tank comes in at 50L which makes it suitable for most camping vehicles. If you’re planning on spending a lot of time on a pitch, this may be the right size for you.
The tank’s smaller size also means lighter weight. It weighs just 2.5kg which is great news for your caravan’s payload.
It’s also a very durable tank and designed not to fail. The manufacturers blow mould it from food-grade high-density polyethylene.
However, this caravan grey water tank presents several potential issues.
Firstly, the size won’t suit everybody. If you’re planning on spending a lot of time off the grid and away from suitable dump points, a bigger tank may be required. The same applies if you have several people in the vehicle.
You will need to drill a 3-4mm hole in the top of the tank to allow for air venting. This may be irritating for those who prefer to avoid DIY and want a more plug-and-play type solution.
Another problem is that this greywater tank may swell when full. It will fill relatively quickly so this is important to keep an eye on.
70L Fiamma Water Tank
Honourable Mention
Fiamma is a brand leader in the world of caravan appliances.
Most caravan enthusiasts will be familiar with this Italian manufacturer. Their caravan grey water tanks aren’t cheap but they are well made and come with a one-year warranty.
Like the smaller Universal tank, Fianma makes it from non-toxic plastic. However, it holds an extra 20L so you won’t have to empty it as often.
It comes with all of the fittings for installation. This includes clamps, so it can be easily mounted on walls or floors. Meanwhile, you can place it horizontally or vertically for greater flexibility.
This caravan grey water tank weighs less than 5kg so it’s not heavy at all.
However, the $179 price point may put off a lot of potential customers because it’s possible to buy bigger tanks at a cheaper cost.
