To simplify assistance to bathing by a bathing assisting tool which proves useful when an assisted person needing light assistance is taking a bath.

By being provided with a sitting section 2 of an assisted person in the upper portion of a float 1 including a countless number of fine closed pores and made of a material floating in a bath, resisting at least its deadweight, the bathing assisting tool delays the sinking of the assisted person into the bath by buoyancy acting on the float 1 and resistance of the bath acting on the underside of the float 1 when the float 1 sinks.
