What Is a Sitz Bath—And How Do You Take One?

A sitz bath is a warm, shallow bath you sit in to soak your anus and its surrounding area. The word sitz is actually derived from the German term sitzen, which means to sit.¹

You can take a sitz bath in a store-bought plastic basin that attaches to the toilet seat or in your own bathtub. For 10-15 minutes, you sit in the bath so that your anus, genitals, and area between (perineum) are covered by the water.² 

Some people might take sitz baths to get a thorough, gentle cleansing. Sitz baths can also be used to help relieve pain or discomfort from certain surgeries or conditions.³

The baths provide relief by improving blood flow and relaxing the muscle around the anus, a muscle known as the internal anal sphincter.² The warm water may also include additives, such as Epsom salt or prescribed medication, to help further.

What Is a Sitz Bath Used For?

Sitz baths can soothe pain and discomfort caused by a variety of issues. You may also take a sitz bath as part of the recovery of a recent procedure or as a way to help manage certain conditions.

May Help in Treating Hemorrhoids

Hemorrhoids are swollen veins around your anus (external hemorrhoids) or in the lining of your anus and lower rectum (internal hemorrhoids). They can develop if you put too much pressure on those veins when doing things like sitting on the toilet for too long or straining while making a bowel movement.⁴

External hemorrhoids can cause pain and itching while internal hemorrhoids can cause rectal bleeding. Using a sitz bath a few times a day can be a way to treat hemorrhoids and stop their side effects.⁴

May Speed Healing After Certain Surgeries

An episiotomy is a minor surgery sometimes performed during vaginal childbirth to help in delivery. The surgery involves cutting the perineum—the skin and muscles between the vaginal opening and anus.⁵

If you’ve recently had an episiotomy, a sitz bath may help quicken the healing process. The bath might also make the recovery less painful. This is due in part to the bath’s warmth, which can relax muscles after just 5-10 minutes of soaking. Those relaxing effects can then last for up to 70 minutes after you finish the bath.⁶

What you add to the warm bath water may also make a difference. Research shows that when myrrh gum extract is included in a sitz bath, people who had an episiotomy had significantly less redness and better wound healing than those who took a sitz bath in saline solution (a mixture of sodium chloride and water).⁷

A sitz bath is also commonly recommended after a hemorrhoidectomy, a surgery to remove internal or external hemorrhoids. However, research has been mixed as to whether the bath can actually provide pain relief or improve healing after this type of surgery.⁶

Could Improve Pain During Pregnancy or After Birth

When you are pregnant or have recently given birth, you may develop blood-filled (thrombosed) internal hemorrhoids.⁸

During pregnancy or after birth, you may also have perianal thrombosis, a collection of blood under the skin in the area around the anus.⁸

To help with both of these common conditions, healthcare providers will often recommend sitting in a warm sitz bath. The bath can improve blood circulation in the anal tissue. The bath can also ease pain associated with the two conditions by reducing muscle tension in the anal sphincter.⁸

Together with oral pain relievers, this treatment will usually bring relief.⁸

May Be Helpful in Managing Certain Infections and Diseases

People undergoing chemotherapy for acute leukemia (a type of blood cancer) may experience perianal infection as a treatment complication. The infection shows as a mass around the anus. The mass can be red, swollen, warm, and painful.⁹

A sitz bath that includes a matrine solution (an anti-inflammatory substance made from Chinese herbs) could help significantly improve symptoms of the perianal infection. Research shows that this type of sitz bath can reduce the size of the mass and also lessen pain and inflammation. A sitz bath without matrine solution does not appear to have the same effect.⁹

Some people with monkeypox may also experience relief with a sitz bath. Monkeypox is a disease that can cause a rash on several areas of the body, including on or near the genitals or anus. The rash may be painful or itchy.¹⁰

Sitting in a sitz bath might provide relief from the rash. A healthcare provider may prescribe medication like the antiseptic povidone-iodine (Betadine) or other products for you to add to the water.¹¹

You might also get relief for your monkeypox symptoms if you add any of the following to the water:¹¹

• Epsom salt 
• Vinegar
• Baking soda

How To Use a Sitz Bath

To get the lasting benefits of a sitz bath, you should likely use it two or three times a day. There are a couple of ways you can take a sitz bath: by sitting in a store-bought basin or in your tub.

Here is how to use both types of sitz baths:

Instructions for Using a Sitz Bath in a Basin

You can purchase a sitz bath online or at the store. These basins are round and shallow and usually fit over the rim of a toilet. 

If you decide to use a basin kit, check the specific instructions you find inside the box and follow them.

Generally, you will need to take the following steps when using a basin sitz bath:¹²

1. Open the kit, and familiarize yourself with the components.
2. Rinse the basin to ensure it is clean.
3. Lift the toilet seat, and set the basin on the toilet bowl. This should fit nicely in place.
4. Pour some warm water into the basin. Leave about a third of the basin empty so there isn’t too much water that overflows when you sit down. The water should be comfortably warm—not too hot. Test the temperature by putting a drop on your wrist.
5. Mix in any additives, such as Epsom salts, baking soda, or prescribed medication, that your healthcare provider recommends. Carefully swirl this around so that it dissolves.
6. Sit comfortably on the basin and remain there for 10-15 minutes.
7. Get up, dry off, and pour out the water.
8. Clean the basin for your next use.

If you prefer, you can also put the basin in a bathtub and use it there.¹¹

Instructions for Using a Sitz Bath in a Tub

If you’re using a bathtub, take the following steps for a sitz bath:¹²

1. Make sure the tub is clean.
2. Fill the tub with about 2-3 inches of warm water.
3. Pour in any additives your healthcare provider may have recommended, and swish them until they dissolve. 
4. Get into the tub. Instead of sitting up straight, lean backwards so that the water can reach the entire area.
5. Remain in the tub for 10-15 minutes before draining the water and patting yourself dry.

When To Contact a Healthcare Provider

If you are using a sitz bath to treat your hemorrhoids and your symptoms don’t improve after one week, you should contact a healthcare provider. You should also reach out if the skin around your anus becomes dry or you develop a rash in the area after using the sitz bath.

You should get immediate medical care if you experience severe pain in your anus along with rectal bleeding. This is especially true if you have abdominal pain, diarrhea, or fever.¹³

If you are using a sitz bath for reasons other than hemorrhoids, such as an episiotomy or perianal infection, you should seek medical care if pain or other symptoms worsen.¹⁴¹⁵

A Quick Review

A sitz bath is a shallow, warm bath you sit in to soak your anus and the surrounding area. As you sit in the bath, the water promotes blood flow and loosens muscles. Taking a sitz bath can have several benefits, including help in the treatment of hemorrhoids, recovery after surgery, and management of certain infections and diseases.

A sitz bath can be taken in a store-bought plastic basin that attaches to a toilet. You can also make your own sitz bath in your bathtub. Besides water, a sitz bath might have additives like medication or baking soda for added relief. To get the desired benefits, you’ll likely need to sit in the sitz bath two or three times a day for 10-15 minutes at a time. Make sure to follow the device’s instructions—as well as any guidance from your healthcare provider—when using a sitz bath.
