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 heat exchange means 41 consists of a cylindrical body 43 for forming a refrigerant channel 42 in its thickness, and wiper bodies 44A and 44B that can freely travel on inner and outer surfaces 43a arid 43b of the cylindrical body 43. By passing a refrigerant to the refrigerant channel 42, water in the bath 11 can be frozen or heated. By moving the wiper bodies 44A and 44B on the inner and outer surfaces 43a and 43b, the freezing-up on the inner and outer surfaces 43a and 43b can be prevented, and water in the bath part 11 can be mixed appropriately. |
