The invention provides a splashing-preventing liquid-storage laundry platform, which comprises a first grid and a second grid that are formed by grid bars at intervals, wherein the tops of the grid bars of the first grid are bulged, the grid bars of the first grid and the second grid are arranged in a staggered way and the second grid is lower than the first grid, sliding airtightness is formed between the grid bars of the first grid and the second grid, the same ends of the grid bars of the second grid are provided with bosses and hinged with a rotating shaft, and the other ends of the grid bars of the second grid are provided with a telescopic rod for adjusting end height. The grid bars of the first grid are arranged at intervals, when a hydrant is turned on, a water stream impacts the tops of the grid bars of the first grid or falls into the spaces among the grid bars of the first grid, the water stream is blocked by the bosses at the tops of the grid bars and mostly transversely splashed or blocked at the spaces among the grid bards, so as to greatly reduce splashing; meanwhile, when the non-boss ends of the grid bars of the second grid turn up, a water storage tank can store water under the cooperation of the bosses and the turn-up of the non-boss ends of the grid bars.
