To provide a bath device capable of accurately estimating a deep body temperature of a bather during bathing and successfully preventing a poor health condition from being caused by rise of the deep body temperature.SOLUTION: A water heater includes a notification treatment section that when it is determined that a deep body temperature of a bather estimated by a human body thermal model HM has risen by a predetermined temperature rise threshold value or more that causes a concern about a poor health condition since start of bathing in a bathtub 2 on the basis of hot water temperature data from a temperature sensor, causes a speaker to make a predetermined notification. The human body thermal model HM is formed by dividing a human body into a skin layer SK, a core layer CR that is a human body center side of the skin layer SK and an intermediate layer MD between the skin layer SK and the core layer CR, and includes at least heat transfer between hot water in the bathtub 2 and the skin layer SK, heat transfer between the skin layer SK and the intermediate layer MD and heat transfer between the intermediate layer MD and the core layer CR. On the basis of a calculation formula obtained by the human body thermal model HM, a temperature of the core layer CR is calculated as the deep body temperature.SELECTED DRAWING: Figure 4 【課題】入浴中の入浴者の深部体温を精度良く推定でき、深部体温の上昇による体調不良症状の発症の予防が良好に行え得るふろ装置を提供する。【解決手段】給湯装置は、温度センサからの湯温データに基づいて、人体熱モデルＨＭにより推定された入浴者の深部体温が、浴槽２内への入浴開始から体調不良症状が懸念される所定の温度上昇閾値以上上昇したと判定した場合に、所定の報知をスピーカに行わせる報知処理部を備える。人体熱モデルＨＭは、人体を、皮膚層ＳＫと、皮膚層ＳＫよりも人体の中心側となるコア層ＣＲと、皮膚層ＳＫとコア層ＣＲとの間の中間層ＭＤと、に分割し、少なくとも、浴槽２内の湯水と皮膚層ＳＫとの間の熱移動、皮膚層ＳＫと中間層ＭＤとの間の熱移動、および、中間層ＭＤとコア層ＣＲとの間の熱移動を含む。人体熱モデルＨＭにより得られる計算式に基づいて、コア層ＣＲの温度が深部体温として算出される。【選択図】図４
