A water thrifting bath-tub is disclosed. The bath-tub has a size allowing a person to sit in it to wash one's body and is smoothly declined to the sewage outlet. A foot part cave-in is formed on the bottom at a position around the outlet so as to allow a person to place one's feet therein when sitting in the bath-tub. The edge (5) between the cave-in (3) and the remaining part of the bottom (2) is curved. When a person sits in the bath-tub, the top of the bent knees of the person is reduced by the depth of the cave-in (3) , and so the bath-tub effectively thrifts water filled in the bath-tub to immerse the whole body of the person. The bath-tub does not force a person to much bend one's knees while sitting in the tub, thereby being free from giving a negative effect to the joint of the knees. The bath-tub also reduces the amount of wasting water and thereby effectively reduces environmental pollution, particularly, sewage water pollution. |
