The utility model relates to the technical field of bathroom goods, and particularly relates to a device for preparing shower gel. The device comprises a stirring pot, and a stirring mechanism arranged in the stirring pot, and further comprises a water storage tank, a material storage tank and an emulsifying pump, wherein the water storage tank and the material storage tank are respectively connected with a liquid feeding hole of the emulsifying pump through liquid feeding pipes, valves are arranged on the liquid feeding pipes, and a liquid outlet of the emulsifying pump is connected with the stirring pot through a liquid discharging pipe. Sodium fatty alcohol polyoxyethylene ether sulfate can be rapidly dispersed in water by the emulsifying pump; because no air is mixed in the process of dispersing the sodium fatty alcohol polyoxyethylene ether sulfate in water, thus foams are prevented from being generated, defoaming waiting is not required, and thus the dissolving efficiency and the production efficiency of the shower gel are increased.
