Enduramaxx 1000L Slimline Rainwater Tank review
A full tonne of rainwater, UK-made, in a side-return-sized footprint.
By Tom Rowland · Updated 20 July 2026 · Price checked against our tracker
The garden-scale ceiling: a thousand litres in a UK-manufactured slimline tank that fits a side return or the strip behind a garage. If you irrigate a serious vegetable plot, this is the difference between a water butt that's empty by mid-June and a reserve that carries you through a dry spell — which is exactly when it matters. A tonne of water demands respect: a flat, load-rated base (a proper slab, not gravel), and it's garden water, not drinking water, without treatment.
