The invention discloses a production method of a glass fiber reinforced concrete stone-like bench. The glass fiber reinforced concrete stone-like bench is of a hollow structure and comprises a bench top plate and side supporting plates. The production method of the glass fiber reinforced concrete stone-like bench includes the following steps that a, a mould is made according to a bench model, and the surface and side faces of the mould are sprayed with a colorful decorative finish which is 2-3 mm thick; b, a rebar reinforced layer is arranged, sprayed with a GRC structure which is 2-3 cm thick, and coated with a film to maintain moisture, hydration is promoted, and demoulding is realized in one day; c, film covering is performed for maintenance after demoulding, the outer surface is subjected to acid pickling in one to two days, colors of internal colored sand are exposed, and a semi-finished bench is obtained; d, the semi-finished bench is maintained with water for 1-2 h, the outer surface is smeared with a water repellent agent layer to obtain the stone-like bench. The invention further provides the glass fiber reinforced concrete stone-like bench manufactured through the production method. In this way, the processing steps are simple, and the obtained stone-like bench has the advantages of being low in mass, bright in color and not prone to cracking and having texture like sandstone.
