Overview of Sitz Bath. A sitz bath is a bath in just enough water to cover the buttocks, upper thighs and lower abdomen. It is more labor intensive than other hydrotherapy treatments, but it powerfully affects the pelvic and abdominal organs.
1 Place the sitz bath on the toilet seat in a way that it does not move. 2  Fill it up with warm water; make sure that the water is not too hot. 3  Some sitz baths have vents so that the water does not overflow and spill out when you sit. 4  If your sitz bath does not have vents, make sure you do not overfill it.
