The Garantia Sunda Wall Tank is a 300-litre rainwater harvesting tank with a realistic rattan-effect finish — designed to sit alongside garden furniture rather than be tucked out of sight. Manufactured by Graf, sold under their Garantia range, it connects directly to your downpipe to collect naturally soft rainwater for garden irrigation. Built from 100% recycled plastic, with a threaded tap connection that requires no drilling, and wind protection and inlet seal DN 19/32 included.
Its slim 400mm depth keeps the footprint compact while delivering serious storage capacity for a wall-mounted tank.
Key features
Rattan-effect finish – Mocca colour suits patio and garden furniture settings; no need to hide it away
300L capacity – high-volume storage in a slim wall-mounted profile
Threaded tap connection – tap installs without drilling
Tap included – easy water extraction via tap or universal hose kit
Wind protection and inlet seal DN 19/32 included – for a secure, watertight installation
Setup kit included – everything needed to connect to your downpipe except the diverter
100% recycled plastic construction – UV-stable and weather-resistant
A setup kit is included, but 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."
