PROBLEM TO BE SOLVED: To develop a bath apparatus capable of increasing the concentration of carbon dioxide in water and facilitating construction work, and a carbon dioxide introduction unit.SOLUTION: The bath apparatus 1 includes a heat source part 2 for heating water, and the carbon dioxide introduction unit 3 as a unit separate from the heat source unit 2. A reheating circulation circuit 55 is configured between the heat source part 2 and a bath tub 5. The carbon dioxide introduction unit 3 includes a carbon dioxide dissolving apparatus 83 for dissolving carbon dioxide in water. In the carbon dioxide dissolving apparatus 83, carbon dioxide is dissolved in normal temperature water or water near normal temperatures supplied from a water supply flow passage 84. The gas-dissolved water is introduced to the reheating circulation circuit 55 via a gas-dissolved water connecting flow passage 77 and supplied to the bath tub 5. Thereby, hot water of appropriate temperatures containing a high concentration of dissolved carbon dioxide can be accumulated in the bath tub 5. |
