The invention provides a soaking water tank and equipment for soaking tiles, and belongs to the field of building equipment. The soaking water tank comprises a tank body, a separating plate, two water pumps, a water level detector, an alarm and drying racks for placing the tiles. The tank body is separated into a first soaking cavity and a second soaking cavity through the separating plate, a first single-way valve and a second single-way valve are arranged on the separating plate, the water outlet of one water pump communicates with the first single-way valve, and the water outlet of another water pump communicates with the second single-way valve. Drying racks are arranged in the first soaking cavity and the second soaking cavity correspondingly. The water level detector is arranged in the first soaking cavity and/or the second soaking cavity, and used for detecting the height of the water level in the first soaking cavity and/or the second soaking cavity, and the alarm is mounted outside the tank body. The tiles are convenient to soak in the using process of the soaking water tank, the tiles are not prone to being damaged in the soaking process, the tiles after being soaked can complete drying action, so that the construction efficiency is improved greatly, and the construction quality is enhanced.
