A swimming pool is constructed from a tank having sidewalls supported against the outwardly acting water pressure only by engagement along their upper edges with a surrounding platform braced along its outer circumference against a peripheral sill or set of posts sunk into the soil at a distance from the basin. The space between the sidewalls of the basin and the peripheral support means is largely empty and accommodates water supply ducts as well as troughs to catch the overflow spilling across the platform; when provided with a fluidtight bottom lining, this space can also serve for the temporary storage of excess pool water.
