If youíre taking a sitz bath in the bathtub, the first step is to clean the tub. Mix two tablespoons of bleach with a half-gallon of water. Scrub the bathtub and rinse thoroughly.
Next, fill the tub with three to four inches of water. The water should be warm, but not hot enough to cause burns or discomfort. You can test the temperature of the water by placing a drop or two on your wrist. When you have found a comfortable temperature, add any substances your doctor recommended for the bath.
Now, step into the tub and soak your perineum for 15 to 20 minutes. Bend your knees or, if possible, dangle your legs over the sides of the tub to keep them out of the water altogether.
When you get out of the bathtub, gently pat yourself dry with a clean cotton towel. Donít rub or scrub the perineum, as this may cause pain and irritation.
