The basin (1) has a bottom (2), and a peripheral wall (3) defining an enclosure of the basin, where the wall is formed of prefabricated panels (4). A permanent holding unit holds the panels in upright position. The holding unit includes tie rods (51), where each tie rod extends between the peripheral wall and the bottom by connecting the wall and the basin. Each tie rod is coupled to the peripheral wall and the bottom by removable connections (6, 7). Sealed inner coating covers the bottom and a portion of inner face of the wall and tie rods. |
