The best sitz baths for hemorrhoids

A sitz bath is a shallow soak of the anal area in warm water. You can do it in a bathtub or in a basin that sits on the toilet. The NIDDK’s page on hemorrhoid treatment suggests sitting in warm water, several times a day, to help relieve pain ¹. MedlinePlus says to sit in warm water for 10 to 15 minutes ². For most people, a foldable basin is enough. Our step-by-step page on how to take a sitz bath covers the same soak if you want the moves without the product comparison.

If you are buying one basin, start with the one that sits steady and folds flat. Choose a wider seat if your hips do not fit a narrow rim. Choose a simple basin if you only need a few soaks. Add a fountain only if you want the water to move. A scented powder is optional, and the trials used plain water.

The honest summary of the research: warm soaks are widely advised, the data are limited, and the surgery trials do not all agree. Use a soak for comfort during a flare. Do not expect it to replace fiber.

Our picks compared

Four basins and one optional soak. The differences are width, a hose, a fountain, and whether you want anything in the water besides warmth.

Reviews of our picks

These notes follow the listing details and the complaints that repeat: a narrow seat, a hose that fails, rubber that tears, and a shorter record for the newest basin.

How we chose these sitz baths

We started with basins that had strong overall ratings from a large number of buyers, and we read recent reviews for the same praises and the same complaints. Steady on the toilet, easy to store, and easier than a bathtub show up over and over. So do narrow seats, liners that rip, and hoses that break.

We then checked that against the studies. Those studies use plain warm water for about 10 to 15 minutes. They do not test brand-name basins, fountains, or scented salts. So the basin choice is about fit and cleanup. The Fivona is the default because buyers describe it as steady, including after childbirth and after hemorrhoid surgery, and it folds away. The Pochik stays for wider hips and for people who want to add warm water mid-soak. The RUGUO stays as a simple basin without extra parts. The Msiori has a shorter public track record than the others. Buyers so far describe a sturdy fit and a fountain piece that comes out for cleaning, and no single complaint has piled up yet. A shorter record means we are less sure how it holds up after a year. The scented soak is on the list only as an optional add-in. It is not a treatment the trials tested.

What the research says about sitz baths

The AGA clinical guidance on hemorrhoids says dietary changes, fiber, and avoiding straining or long toilet sits are reasonable first steps. It also says sitz baths are often advised for symptom relief, and that the scientific data are limited ³. The NHS page on piles says to take a warm bath to ease itching and pain ⁴. The American College of Obstetricians and Gynecologists says sitting in a bath of warm water may relieve hemorrhoid symptoms ⁵. After surgery, the ASCRS patient page on hemorrhoids says a warm sitz bath for 10 to 15 minutes, two or three times a day, can help ⁶.

One pregnancy study is more enthusiastic than the surgery trials. A 2018 comparative study of sitz baths in pregnancy followed 495 pregnant women in Saudi Arabia ⁷. One group (284 women) used a warm salty sitz bath three times a day. The other (211 women) used a topical cream twice a day. Both groups also used glycerin suppositories before bowel movements and a daily fiber supplement. The authors reported complete healing in all 284 women in the sitz group and in 179 of 211 (84.8%) in the cream group. This was a prospective comparison, not a randomized trial, and the sitz bath was not the only care either group received. A protocol that included warm soaks three times a day looked better in that clinic. A basin was not the only difference between the groups.

A 2005 review of sitz bath evidence searched the medical literature and found the support thin ⁸. The authors located one randomized study comparing a sitz bath with placebo, and they did not find enough data to prove sitz baths treat anorectal disorders. Papers they collected suggested that warm water relaxes the internal anal sphincter, the ring of muscle that keeps the anus closed. Cold sitz baths were reported to reduce perineal swelling more than warm ones, while patients tended to prefer warm water. The review also listed case reports of harm, including burns, spread of herpes, and a maternal-neonatal strep outbreak. It did not test modern toilet-top basins. The practical reading is to use your own clean basin, and to keep the water warm rather than hot.

Physiology studies explain why warm water might ease a cramp. In a manometry study, resting anal pressure fell after immersion at 40 degrees Celsius and did not fall at 5 degrees or 23 degrees ⁹. After 5 minutes of that warm water, the drop lasted about 15 minutes in volunteers and about 30 minutes in patients who had hemorrhoids, fissures, or a fleeting anal pain. A separate study sat 18 healthy volunteers and 28 patients (18 with fissures and 10 with hemorrhoids) in warm baths at 40, 45, and 50 degrees Celsius for 10 minutes at each temperature ¹⁰. Pain relief was stronger, and lasted longer, at the higher temperatures. Sphincter pressure dropped in the bath and returned to baseline over 25 to 70 minutes afterward. The muscle temperature they measured did not change, so the author thought a nerve reflex was the likely path, not the water heating the muscle directly. Fifty degrees Celsius is hot enough to burn. Do not copy the hottest lab bath at home.

The 50-person trial compared pain pills alone with the same pills plus a twice-daily soak. Pain scores were not significantly different (P = 0.234), and painkiller use was not either (P = 0.435). The 2024 trial put 32 people in each group after surgery for grade III or IV hemorrhoids, the grades that slip out. A soak starting 6 hours after surgery lowered pain by about 0.8 points (confidence interval 0.18 to 1.44) and did not change trouble passing urine. If your surgeon told you to wait, wait. The ice comparison is on our ice pack page and in ice or heat for hemorrhoids. At 24 hours, more people in the ice group had little or no swelling.

A warm shower spray is another option the trials have looked at. In 120 people after hemorrhoidectomy, pain, irritation, and hygiene scores were similar with a warm water spray or a sitz bath ¹⁴. The spray group found it more convenient and were more satisfied. Wound healing at four weeks was 90% with the spray and 93% with the sitz bath. If a basin is awkward, a gentle warm rinse can stand in. Our bidet picks are the at-home version of that idea. A 2025 trial compared an electronic bidet with warm sitz baths for seven days after hemorrhoid surgery. Pain scores on day 7 were similar (38.3 with the bidet versus 42.0 with sitz baths, P = 0.453), and the trial did not confirm that the bidet matched soaks closely enough for the comparison the authors planned ¹⁸. Treat a rinse as a stand-in when a basin is awkward.

Fiber still has the clearer evidence for bleeding. A 2006 meta-analysis of seven fiber trials found fiber cut bleeding risk by about half ¹⁶. A soak will not do that. Hemorrhoid home remedies sorts soaks from remedies that have less behind them. Hemorrhoid treatment is the wider map if home care is not enough.

Which sitz bath to buy

Buy the basin that fits your toilet and your hips. The water does the work the studies describe. The plastic is there so you do not have to fill a tub.

The Fivona suits most people, especially after childbirth or surgery, when climbing into a bathtub hurts. August reviews praise how steady it feels and how flat it folds into a cabinet. The split is size. Wider hips sometimes find it narrow. If that is you, do not force it.

The Pochik is the wider, deeper basin, with a flusher hose for topping up warm water while you sit. Buyers call it a help in pregnancy and after birth, and they say it fits round and elongated toilets. Plain water works in it. Durability is the weak spot: a few people report a torn liner or a hose that breaks early. If you do not need the hose, you do not need this extra part.

The RUGUO is the basic foldable basin. It fits under most seats, stores under the sink, and is easy to clean. People describe relief on painful days. Some find the rubber section tears with regular use. Choose it when you want a simple soak and you are not counting on the basin for years of daily use.

The Msiori adds a small fountain. There is no trial showing that moving water heals hemorrhoids faster than still warm water. Buy it if you want that sensation and you like that the fountain piece comes out to wash. The storage bag is part of the listing. Because the track record is shorter, check it after a few weeks of use. If the seal weeps or the pump fails, a still-water basin is the backup, and the soak itself does not depend on the motor.

The Better Bath soak is a large resealable pouch people stir into warm water. Buyers like the scent, say it dissolves quickly, and often use it in postpartum routines. The complaint is cost compared with plain bath salt. Skip it if your skin reacts to fragrance. The pregnancy study used salty water, not a scented mix, and even that salt was part of a package with fiber. We would not add a measured dose of salt at home on the strength of that one study. Plain warm water is the version the physiology studies used.

How long and how often to soak

During a flare, 10 to 15 minutes, two or three times a day, matches MedlinePlus, the ASCRS post-surgery advice, and the three-times-a-day pregnancy protocol ^2,6,7. NIDDK says several times a day without a minute count ¹.

1. Wash the basin with soap and water. Let it sit steady on the toilet. If it rocks, it is the wrong shape for that seat.
2. Fill it with warm water, only to the overflow holes. Test it on the inside of your wrist. It should feel like a warm bath, not like the hottest tap.
3. Sit for 10 to 15 minutes. If the water cools early, add warm water through a hose if you have one. If you do not, empty and refill. Do not pour a just-boiled kettle over your lap while you are sitting.
4. Pat dry. Rubbing itchy skin makes it worse. The NHS says to pat rather than rub, and to keep the area clean and dry ⁴.
5. Repeat two or three times on days when the area is sore. You can use the timer below for the 10 to 15 minutes.
6. Wash the basin again and let it dry before you fold it away.

After surgery or birth

Ask your surgeon before the first soak. One trial’s comfort benefit came from starting at 6 hours, and another trial found no pain benefit at all ^11,12. The recovery timeline after hemorrhoidectomy is the week-by-week picture, including the first bowel movement. If you cannot get into a tub, a toilet basin is the reason these products exist. Buyers who used a basin after surgery often say that was the point.

After a vaginal birth, a basin is easier than a deep tub while stitches are sore. Warm water is the ACOG suggestion ⁵. Our postpartum hemorrhoid guide covers how long symptoms often last and what is reasonable while breastfeeding. A local warm soak is not a drug. Bleeding, fever, or a soak that stings a repair are reasons to call your obstetric provider. Hemorrhoids during pregnancy is the page to read before the birth, when soaks are already part of conservative care.

What to do if a soak is not helping

Give it a few days of 10 to 15 minute soaks, not one hurried sit. Then change something specific.

1. Check the temperature and the time. Lukewarm water for two minutes is not the soak the guidelines describe. Scalding water is not safer, it is a burn risk ¹⁵.
2. If the outside is swollen and throbbing, add a wrapped cold pack at a different time of day. Ice did better than soaks for early pain after surgery in the 2025 trial ¹³.
3. Soften the stool. Fiber is the intervention that cut bleeding risk in pooled trials ¹⁶. A soak does not.
4. If the basin is the problem (narrow, tipping, or a broken hose), switch basins. The water is the treatment. The plastic is replaceable.
5. If about a week has passed and pain or bleeding is no better, see a doctor. NIDDK uses that one-week checkpoint for over-the-counter hemorrhoid products ¹. A soak deserves the same limit. How to get rid of hemorrhoids fast is the 48-hour plan if you are still in the first two days.

When to see a doctor instead

The NHS lists painless bleeding, pus, and feeling feverish as reasons to get prompt advice ⁴. The US Preventive Services Task Force recommends colon cancer screening for adults 45 to 49 and more strongly for adults 50 to 75 ¹⁷. New bleeding in those years should be checked even if a soak makes the itch better. Our page on when to see a doctor for hemorrhoids lays out same-day symptoms versus a routine visit. Stop if the water burns, and get examined if a week of soaks has not changed the pain or the bleeding.
