A sitz bath is one in which the hips and buttocks are put in water.
It is usually used to promote healing and symptom relief around the bottom,
such as for hemorrhoids, or genitals, such as for pain following
childbirth.
There are different types of sitz baths to choose from, many of
which can be purchased at medical supply stores. A common type is a basin that
fits on a toilet seat and is filled with water.
