Garantia 2-in-1 Water Collector & Planter – 300 L, Zinc Grey

£410.39

The Garantia 2-in-1 Water Collector & Planter combines a 300-litre rainwater storage tank with a removable planter cup on top. Manufactured by Graf, sold under their Garantia range, it collects rainwater from both your downpipe connection and the planter cup above, making the most of every rainfall. The removable planter cup makes it easy to grow flowers or plants on top, clean the inside of the tank, and customise the look to suit your garden.

Built from 100% recycled plastic, with a 3/4" brass thread for tap connection without drilling. Inlet seal DN 19/32 and plant fleece included.

Key features

  • 2-in-1 design – collects rainwater via downpipe connection and integrated planter cup; removable cup for easy cleaning and planting

  • 300L capacity – larger storage volume than the Natura and VASO equivalents

  • Chrome or brass tap included – connects via integrated thread without drilling

  • 3/4" brass thread – tap installs without drilling

  • Inlet seal DN 19/32 and plant fleece included – inlet seal ensures a watertight downpipe connection; plant fleece lines the planter cup to retain compost without blocking drainage

  • 100% recycled plastic construction – UV-stable and weather-resistant

  • Zinc Grey finish – works as a garden feature rather than something to tuck out of sight

Connecting to your downpipe

A downpipe diverter is required separately — add one to your order below. If you're connecting to a square downpipe, you'll need the Square Downpipe Diverter specifically.

Per Graf's installation guidance: "The water butts do not come predrilled. This product is very easy to use and can be drilled in by anyone. Simply attach the drill bit onto your drill and begin drilling – remember you must drill the hole in the water butt at the same level as the hole in the downpipe! As long as the holes drilled in both the water butt and the downpipe are level, the water will continue down the downpipe when the water butt is full."
