The invention is directed to a method of preparing bathtub with cushion and a bathtub with cushion, and more particularly, a method of preparing bathtub comprising a first operation of forming an external structure layer forming an external appearance of a bathtub; a second operation of forming a mold-release agent layer having a bathtub forming surface corresponding to an internal shape of the bathtub and a flange extending from a circumference of the bathtub forming surface to the outside, on an external surface of an internal mold; and a third operation of forming a semi-rigid foam layer having a soft foam layer and an unfoaming painted layer formed sequentially between the external structure layer and the mold-release agent layer by being injected in a space between the external structure layer and the mold-release layer. In virtue of the present invention, there is provided a bathtub with cushion function having a good contact feeling with regard to the inside layer of the bathtub, giving comfort due to its cushion, securing safety from impact due to its elastic material, having such an excellent warmth keeping ability that there is no need to refill water during bath, and being able to be utilized even as a bed or cradle after bath especially in case of being applied to bathtubs for infants. Further, it enables to manufacture a cushioned bathtub with a low cost due to a simplified manufacturing process and thereby reduction of unnecessary production loss and manufacturing costs. |
