The present invention is directed to a light weight booster bath that will consist of a two-piece reinforced tub unit, removable legs, drain hose, spray nozzle, utility basket, three-piece adjustable leash system with collar and assembling hardware that will fit within the nested upper and lower portion of the tub. Optional leg stabilizers and access stairs can also be part of the package additionally fitting within the nested upper and lower portion of the tub. A unique three-piece adjustable leash system will be attached to the combined tub sections by eyebolts.
