The invention discloses a fiberglass coated water container which includes an inner liner, a thread interface fixedly connected at the neck of the top part or the bottom part of the inner liner as well as a fiberglass coated layer coated outside the inner liner to carry out pro+tection on the inner liner. An annular embedding structure used for embedding and fixing the end part of the fiberglass coated layer is correspondingly arranged on the outer wall of the thread interface. The fiberglass coated water container has a simple structure, is conveniently processed and manufactured, can reliably run for a long period and can effectively solve the hidden trouble problem existed in peeling off between the inner liner and the coated layer.
