Prefabricated pool

A prefabricated concrete pool comprising a formwork (28) comprising:

• a floor form (25), for pouring a layer of liquidized concrete thereon, for forming a concrete floor (27);
• a peripheral external wall form (26), disposed on said floor form (25), for limiting a size of said concrete floor (27);
• a peripheral internal wall form (24), disposed above said floor form (25) and near said peripheral external wall form (26), for pouring liquidized concrete between said external (26) and internal (24) wall forms, for forming a peripheral concrete wall (40) therebetween;
• and
• anchoring ties (31), each threaded through said internal wall form (24) and said external wall form (26), for anchoring said internal wall form (24) to said external wall form (26), for applying said disposition of said peripheral internal wall form (24) above said floor form (25),
• thereby said liquidized concrete poured between said peripheral wall forms (24, 26), and said liquidized poured concrete layer attach one another while being liquidized,
• wherein said forms (25, 26, 24) are not fixed to a ground,
• thereby said concrete floor (27) and said peripheral concrete wall (40) are transportable.
