A sitz bath is one of the simplest and most effective home treatments for hemorrhoid pain, and all you need is a few inches of warm water. The warm water relaxes the ring of muscle around your anus (the anal sphincter), which increases blood flow to the swollen tissues, reduces muscle spasms, and promotes healing. Here’s exactly how to do it right.
What You Need
You have two options: a plastic sitz bath basin that fits over your toilet seat, or your regular bathtub. The basin is inexpensive (usually under $15 at any pharmacy or online) and more practical for repeated daily use since you won’t need to fill and clean an entire tub each time. It also keeps the rest of your body dry and makes it easier to get in and out.
If you use your bathtub, fill it with just 3 to 4 inches of water. You’re only soaking your hips and buttocks, not taking a full bath.
Step-by-Step Instructions
Start by cleaning your basin or tub with a disinfecting wipe before each use. Then fill it with warm water. The temperature should feel comfortably warm on the inside of your wrist, similar to what you’d use for a baby’s bath. Water that’s too hot can irritate already inflamed tissue or cause burns in a sensitive area. If you can’t comfortably hold your hand in the water for 10 seconds, let it cool.
Lower yourself into the basin or tub so the water covers your anal area completely. Sit for 15 to 20 minutes. You can gently flex and relax your pelvic muscles a few times during the soak to help the warm water reach the tissue around the hemorrhoid. If the water cools down noticeably before you’re done, add a little more warm water to keep the temperature consistent.
When you’re finished, stand up slowly. Pat the area completely dry with a clean, soft towel or cloth. Don’t rub. Rubbing irritates swollen hemorrhoid tissue and can worsen itching. You can also let the area air dry if patting feels uncomfortable. Leaving moisture on the skin can lead to additional irritation, so make sure you’re fully dry before getting dressed.
How Often to Take a Sitz Bath
For active hemorrhoid flare-ups, aim for two to three sitz baths per day. Taking one after each bowel movement is particularly helpful since that’s when hemorrhoids tend to be most irritated. You can also take one before bed to ease discomfort for sleeping.
Most people notice relief within a few days of consistent use. There’s no strict limit on how many days you can continue, but if your symptoms haven’t improved after a week of regular sitz baths, that’s worth bringing up with a healthcare provider.
Plain Water vs. Additives
Plain warm water works well on its own. The therapeutic benefit comes from the warmth and the immersion, not from anything dissolved in the water. Some people add Epsom salt (about 2 tablespoons per basin), which can feel soothing, but there’s no strong clinical evidence that it speeds healing beyond what warm water alone provides.
Avoid adding bubble bath, scented soaps, or any fragranced products. These can irritate the already sensitive and inflamed tissue around hemorrhoids and make itching worse. If you want to add anything, stick with plain Epsom salt or a small amount of baking soda.
How Effective Are Sitz Baths?
A clinical study comparing sitz baths to topical anorectal cream in pregnant women with hemorrhoids found that 100% of patients in the sitz bath group achieved complete healing, compared to about 85% in the cream group. That’s a meaningful difference, and it suggests sitz baths aren’t just a comfort measure. They actively promote tissue recovery.
The mechanism is straightforward: when the warm water relaxes your anal sphincter, blood circulates more freely through the swollen hemorrhoid tissue. Better blood flow means more oxygen and immune cells reaching the area, which is what drives healing. The muscle relaxation also directly reduces the throbbing, pressure-like pain that hemorrhoids cause.
Sitz baths work well alongside other conservative treatments like high-fiber diets, stool softeners, and gentle topical products. They’re not an either/or choice.
Keeping Your Equipment Clean
If you’re using a plastic sitz bath basin, clean it with a disinfecting wipe after every use and let it air dry. Don’t just rinse it with water and set it aside. Bacteria can colonize damp plastic surfaces quickly, and introducing bacteria to inflamed hemorrhoid tissue increases your risk of infection. Replace the basin if it becomes cracked, stained in a way that won’t clean off, or visibly damaged.
When a Sitz Bath Isn’t Enough
Stop using sitz baths and contact your doctor if your pain or itching gets worse instead of better, if the skin around your anus becomes noticeably red and puffy, or if you develop unusual discharge. Bleeding during bowel movements that doesn’t improve with conservative care also warrants a medical evaluation, since it can signal something beyond a simple hemorrhoid.
If you’re pregnant or recently postpartum, check with your provider about timing before starting sitz baths. And if you have open wounds in the perianal area, skip the sitz bath until a doctor says otherwise, since soaking open wounds can introduce infection.
