The present invention relates to a steam sauna apparatus for home use easily used in the home； capable of reducing indiscriminate power consumption by controlling a heating surface； and capable of receiving functional steam by inserting the sterilization of the steam and a beauty or Chinese medicine functional pack. More specifically, the steam sauna apparatus connects a first, a second, and a third heating board for generating steam by heating the water by receiving the power of a positive pole and a negative pole to a guide inside a body including a filling space in which water is filled by piling the first, the second, and the third heating board. The third heating board (23) constructs the heating unit having a half surface with an insulator and moves the heating unit in the rotation of a spindle shaft by exposing the spindle shaft, in which a female screw is formed at an outer circumference to combine with the male screw of the spindle combined with the first heating board, outside the body. A connector combined with steam exhaust hole formed at an upper side of the body is connected to a wrinkle double pipe in which an inner part is composed of metal and in which an outer part is composed of synthetic resin. A nozzle unit is composed of a cylinder nozzle to spray the steam and is constructed at other end of the wrinkle double pipe. The nozzle of the nozzle unit is connected to a sauna booth to supply the steam. The steam sauna apparatus can reduce an unnecessary heating surface and power consumption by controlling the heating surface by dividing the surface of the heating board.본 발명은 가정에서 쉽게 사용할 수 있으며 발열 면적을 조정하여 무분별한 전력소비를 줄일 수 있으며 스팀의 살균과 미용이나 한방기능 팩을 끼워 기능성 스팀을 제공받을 수 있는 가정용 스팀사우나 장치에 관한 것으로, 더욱 상세하게는 물이 충진되는 충진공간을 갖는 몸체의 내부에서 양극,음극의 전원을 공급받아 발열하여 물의 가열로 스팀을 발생시키는 제1,2,3발열판을 적층형태로 이격 배치하여 가이드로 서로 연결하고, 상기 제3발열판(23)은 1:2비율의 면적으로 절연체를 사이에 두고 분할되어진 상태의 발열부를 구성하고, 상기 제1발열판의 상부로 결합되는 스핀들의 수나선에 나선결합되게 외주면에 암나선이 형성된 스핀들축이 몸체의 외부로 노출되어 스핀들축의 회전시 발열부가 상하로 이동하도록 구성하고
