Sitz Bath After Birth: How to Use One for Perineal and Hemorrhoid Relief

After a vaginal birth, the area between your vagina and anus (the perineum) is often swollen and tender, even if you didn’t tear. Stitches, hemorrhoids and the sting of peeing can make sitting down feel like a project. A sitz bath is one of the simplest things your nurse or midwife may suggest.

Here’s when to start, how to take one safely, what to look for in a basin, and what the evidence does and doesn’t show.

What a sitz bath is and what it’s for

MedlinePlus describes a sitz bath as a warm water bath you sit in, where the water covers only your hips and buttocks. It says sitz baths are often recommended to relieve pain and speed healing after an episiotomy or hemorrhoid surgery, and to ease pain, itching or muscle spasms.

ACOG lists a sitz bath among its tips for perineal pain after a tear or episiotomy, alongside cold packs, a pillow or cushion to sit on, a squeeze bottle of warm water at the toilet, and a stool softener. ACOG also mentions sitz baths for postpartum hemorrhoids, together with medicated sprays or ointments and cold witch-hazel compresses, and suggests a warm sitz bath to lessen swelling and pain if peeing burns in the first days.

Cleveland Clinic explains the idea behind it: warm water relaxes the anal sphincter and improves blood flow to the area. It notes that perineal soreness and swelling can happen after a C-section as well as after a vaginal birth.

What the evidence says

Sitz baths are widely recommended, but good trials are scarce. A 2026 American Gastroenterological Association expert review on hemorrhoids says sitz baths are often advised for symptom relief but that scientific data is limited. Think of a sitz bath as a low-risk comfort measure, not a treatment that will make stitches heal faster on its own.

When to start: cold first, then warm

In the first day, sources recommend cold rather than warmth. MedlinePlus says ice packs in the first 24 hours after birth reduce swelling and help with pain, and advises waiting until 24 hours after birth before taking a warm bath or a sitz bath. ACOG suggests an ice pack or cold gel pack on the perineum for 10 to 20 minutes at a time, and says this works best in the first 24 to 72 hours. Hospital leaflets vary on timing: NHS Tayside, for example, suggests a maximum of 10 to 15 minutes at a time. Wrap ice in a cloth rather than putting it straight on your skin, as the NHS advises.

Cleveland Clinic recommends that anyone who has recently had a baby ask their provider before starting sitz baths, so you get instructions that fit your birth and your stitches.

How to take a sitz bath

1. Clean the basin or tub first. Cleveland Clinic says to clean and rinse the tub thoroughly before each use. For a bathtub, MedlinePlus advises cleaning it with a disinfectant before every bath.
2. Use warm, not hot, water. Cleveland Clinic suggests about 104°F (40°C) and warns that water that’s too hot can burn your skin. Fill to 3 to 4 inches (about 8 to 10 cm), enough to cover your perineum.
3. Soak. Cleveland Clinic suggests 15 to 20 minutes. Advice varies between hospitals: NHS Tayside, for example, asks people with stitches not to sit in a bath for more than 10 minutes until the stitches have dissolved. If your hospital gave you a time, follow it.
4. Pat dry gently. Use a clean towel and don’t rub, as Cleveland Clinic advises. Then put on a fresh pad.
5. Empty and clean the basin after each use and let it dry.

MedlinePlus suggests sitz baths a few times a day; Cleveland Clinic says a provider may recommend three to four a day if they are helping.

Over-the-toilet basin or bathtub?

Both work. MedlinePlus notes that drugstores sell tubs that fit on the rim of the toilet, which you can use instead of climbing into the bathtub. Cleveland Clinic describes kits with a shallow basin that sits under the toilet seat and a bag with tubing that lets you top up warm water as you sit.

	Over-the-toilet basin	Bathtub
Getting in and out	Sit down as you would on the toilet	Lowering yourself into a tub can be hard in the first days
Water needed	A small amount	A few inches in the whole tub
Cleaning	Small and quick to wash	Clean the whole tub before each soak
Privacy and time	Easy to fit in after a toilet visit	Needs more setup time
Cost	A low-cost kit	Free if you already have a tub

What to look for in a sitz bath basin

We don’t rank brands. If you buy a basin, check:

• Fit. It should sit securely on a standard toilet bowl under the seat without rocking.
• Overflow vents at the back so water drains into the toilet instead of spilling.
• A bag and tubing if you want to add warm water as it cools.
• Smooth, easy-clean plastic without deep grooves where water sits.
• Personal use only. Cleveland Clinic advises against sharing a plastic sitz bath.

Should you add Epsom salt, herbs or witch hazel?

Plain warm water is enough. Cleveland Clinic says you don’t need Epsom salt for a sitz bath, that warm water alone works, and that salts, oils and other substances may cause inflammation. It advises adding salt or anything else only if your provider tells you to. MedlinePlus’s discharge instructions after a vaginal birth also say to use plain water and avoid bubble baths or oils.

NHS Tayside’s leaflet says there is no evidence that witch hazel or bath salts speed healing, though they aren’t thought to be harmful if you find them soothing. In short: the evidence for additives is thin, so there is no need to buy them. If you’d like to try one, ask your provider first, especially if you have stitches.

Other ways to ease perineal and hemorrhoid pain

A sitz bath is just one part of perineal care. Sources also suggest:

• Rinse instead of wiping. MedlinePlus advises spraying warm water over the area after you pee or poop, then patting dry instead of using toilet paper. The NHS says to wipe gently from front to back.
• Prevent constipation. MedlinePlus recommends stool softeners, plenty of water and fiber. Straining makes hemorrhoids worse, ACOG notes.
• Take pain relief if you need it. ACOG says ibuprofen is usually the preferred first step while breastfeeding and that acetaminophen is also safe. Our guide to ibuprofen and acetaminophen while breastfeeding explains the evidence; check doses with your doctor or pharmacist.
• Change position for feeds. ACOG suggests breastfeeding lying on your side if sitting is uncomfortable. See our guide to side-lying breastfeeding for how to set it up safely.

When to call your doctor or midwife

Stop the sitz bath and call your provider if your pain gets worse or your perineum becomes red and puffy, as Cleveland Clinic advises. Cleveland Clinic also says to call if pain hasn’t started to improve after two or three sitz baths, as you may have an infection or another cause of pain.

Contact your provider if you notice any of these signs (ACOG, MedlinePlus, NHS):

• Stitches that become more painful, or pain from a tear or episiotomy that doesn’t go away or gets worse
• Redness, swelling or discharge from the tear or cut, or a wound that seems to break open
• Vaginal discharge with a bad smell
• A fever over 100.4°F (38°C)
• Going 4 or more days without a bowel movement
• Passing a blood clot larger than a walnut
• Heavy bleeding that soaks through two pads an hour for more than an hour or two (ACOG calls for a call to your ob-gyn right away)

Call 911 if you have chest pain, trouble breathing, a seizure, severe pain in your lower belly, pain and swelling in a leg, or thoughts of harming yourself or your baby. If you’re struggling with feeding while you recover, our breastfeeding support page lists where to find help.
