[Problem] To provide a footbath container which enables easily and hygienically taking a footbath while showering in a bathroom. More specifically, to provide a footbath container which facilitates drainage of bathwater collected in the container after a shower, the inside surface of which can easily be dried, and which it is easy to hygienically manage. [Solution] This footbath container comprises a base plate 10 having a rectangular shape and two pairs of facing wall plates which can be erected from the base plate. First wall plates 20, which form a pair, have folds 21 provided diagonally upwards from both ends of a bottom edge, and each of the first wall plates 20 can be folded outwards along the folds and collapsed; second wall plates 30, which form a pair, are collapsed inwards, and the footbath container is folded flat. The footbath container is provided with an adhesion preventing means which, in a state in which the footbath container is folded so the first wall plates 20 extend from the bottom plate 10, prevents adhesion at least between the bottom plate 10 and the inner surface of the second wall plates 30.
