Blue Thumb's patented AquaBox® basins are produced in-house. Our 48" Achelous basin is designed to provide a plentiful water reservoir with strength enough to support expensive and heavy fountains on its manageable, lightweight form. This basin also features a 2-piece removable grate top that includes a cut out for easy pump access with a cover to keep debris out when not in use. Additional support columns may be added when using heavier fountains. Made in the USA.
