To provide a device for treating bathtub water capable of rapidly sterilizing the bathtub water by efficiently generating plasma to shorten a time of treating the bathtub water, and a bathtub apparatus.SOLUTION: A gas phase G is generated in the vicinity of a revolution center of a revolving flow F1 of a liquid L1 by revolving the introduced liquid L1. The device includes: a treatment tank 12 capable of attaching a discharge part 17 to a bathtub 90; a pump 50 capable of connecting to the bathtub, and for introducing a bathtub water 92 held in the bathtub from an introduction part into the treatment tank; a first electrode 30 at least a part of which is disposed in the treatment tank, and contacts the bathtub water in the treatment tank; a second electrode 31 disposed so as to contact the bathtub water in the treatment tank; and an electric power source 60 for having the gas phase generate plasma by impressing a voltage between the first electrode and the second electrode. Plasma is generated to the gas phase to sterilize the liquid, and to produce a modified constituent, the produced modified constituent is solved in the bathtub water and dispersed into the bathtub water to produce a treatment liquid L2, and the produced treatment water is supplied into the bathtub from the discharge part.SELECTED DRAWING: Figure 6D 【課題】プラズマを効率良く発生させて浴槽水を迅速に殺菌できて、浴槽水の処理時間を短縮でき浴槽水処理装置及び浴槽装置を提供する。【解決手段】導入された液体Ｌ１を旋回させることにより、液体Ｌ１の旋回流Ｆ１の旋回中心付近に気相Ｇを発生させるとともに排出部１７が浴槽９０に取り付け可能な処理槽１２と、浴槽に接続可能でかつ浴槽に保持される浴槽水９２を、液体として導入部から処理槽内に導入するポンプ５０と、処理槽内に少なくとも一部が配置されて処理槽内の浴槽水に接触する第１電極３０と、処理槽内の浴槽水に接触するように配置された第２電極３１と、第１電極と第２電極との間に電圧を印加して気相にプラズマを発生させる電源６０とを備えて、気相にプラズマを発生させて、液体を殺菌するとともに改質成分を生成し、生成した改質成分が浴槽水に溶解して浴槽水中に分散して、処理液Ｌ２を生成し、生成された処理液が排出部から浴槽内に供給する。【選択図】図６Ｄ
