A bath or basin used indoors or outdoors for fluid storage is provided with a rollable protection in the form of a reinforced sheet fastened around its outer edges and supported by pontoons so that a hollow space is formed between the sheet and the fluid surface in the basin. An absorber is integrated in the sheet. The protective sheet can be rolled onto a winch, with the pontoons emptied of air and the absorber emptied of fluid. |
