The Garantia Extra Slim Stone-Effect Wall Tank delivers 400 litres of rainwater storage in one of the slimmest profiles available — just 280mm deep. Manufactured by Graf, sold under their Garantia range, it's the practical choice for gardens, patios, or side returns where space is tight but storage capacity still matters. Built from 100% recycled plastic, UV-stable and weather-resistant throughout.
At 1840mm tall and only 280mm deep, this tank fits flush against a wall without eating into your outdoor space — and the stone-effect finish in Graphite Grey means it doesn't need hiding away.
Key features
Ultra-slim profile – 280mm deep, fits against virtually any garden wall
400L capacity – serious storage without the footprint
100% recycled plastic construction – UV-stable and weather-resistant
Stone-effect finish – suits urban or rural garden settings
Brass-coloured aqua-quick plastic tap included
Setup kit included – everything needed to connect to your downpipe except the diverter
2-year manufacturer's guarantee
Connecting to your downpipe
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."
