An improved floor-level adjusting device for a pool is particularly designed to be incorporated in an existing pool at low cost without the destruction thereof. The floor-level adjusting device for a pool has a movable floor disposed in a pool for vertical movement, and a plurality of lifting mechanisms disposed on and along the side walls of the pool and connected with the movable floor for moving the movable floor in the vertical direction so that the depth of water in the pool above the movable floor can be adjusted in an appropriate manner.
