Shrubtubs Squares are tree tubs made from 4 mm (0.15 in) thick Corten steel. They contain a volume of substrate up to a maximum of 5 m³ (177 ft³) and are suitable for shrubs and multi-stemmed trees. Bigger city trees depend on this substrate volume.

The Shrubtub Square is a beautiful, sleekly detailed product available with a special double-layer powdercoating. The Shrubtubs can be easily relocated and have anchoring for the root ball. To prevent sagging due to soil pressure, the single-walled sides are reinforced with an upper frame. If necessary, this edge can be deepened to allow grilles to be installed.
