PROBLEM TO BE SOLVED: To provide a heat-storing bath that can be composed compactly and inexpensively while the entire part is integrated. SOLUTION: This heat-storing bath consists of an outer shell part 21, a bath part 11 that is arranged in the outer shell part 21, a heat exchange means 41 that is arranged in the bath part 11, and a lid part 31 for freely blocking the upper opening part of the bath part 11. The bath part 11 is composed of a cylindrical, closed-end inner-layer body 12 made of FRP, and an outer-layer body 13 made of an expanded body being laminated outside the inner-layer body 12. The outer shell part 21 is polygonal, and a corner part is composed by a fresh air heat exchanger 71. By forming the corner part of the outer shell part 21 using a group of fresh air heat exchanger s 71, an entire assembly including an outdoor machine can be made easily by reducing man-hours, and the entire strength of the outer shell part 21 can be secured by the group of fresh air heat exchangers 71. |
