A portable bathtub has several advantages to the user. Firstly, one can use it while on a camp side or at the outdoor activities. You will not get stranded as you visit remote areas where there must be a set up for a temporal bathing place.   Also, it becomes useful when you are renovating your bathroom. You will use it temporarily as you wait for the construction to end. Typically, a portable bathtub is necessary for a traveling lifestyle that involves camping or hiking in remote places.
