How to do a sitz bath at home correctly: 5 steps for effective hemorrhoid pain relief

Hemorrhoids, anal fissures, or anal irritation can cause burning, itching, and discomfort, especially after bowel movements. Sitz baths with warm water are a common home care remedy used to soothe the anal area and relieve discomfort. This method is also known as anal immersion or sitz baths for hemorrhoids.

According to medical guidelines, a sitz bath only requires immersing the buttocks and perineal area in a moderate amount of warm water, which can be done using a bathtub or a specialized sitz bath device. In this article, Tiptory helps experts guide readers on how to properly take a sitz bath for hemorrhoids, from preparing the water and immersion time to important considerations to avoid further irritating the anal area.

Proper sitz bath to relieve discomfort

Prepare warm water and soak for the correct duration

1. Fill a bathtub or clean basin with warm water to a depth of about 7.5–10 cm (3–4 inches). The water level only needs to be deep enough to cover the buttocks and anal area when seated.

2. Sit in the water for about 10–20 minutes. This type of sitz bath can help soothe the pain, burning, and irritation around the anus, commonly experienced with hemorrhoids or anal fissures.

3. The water should be comfortably warm, not too hot. Soaking the anus in excessively hot water can irritate or burn the skin, so do not try to increase the temperature in hopes of faster symptom relief.

Gently dry the anal area

• After a sitz bath for hemorrhoids, gently pat the anal area dry with a clean, soft towel. Do not rub vigorously as this can cause more pain to the irritated area.

• Keep the anal area clean and dry after soaking. If using a bathtub or basin for a sitz bath, clean the device thoroughly before and after each use.

Appropriate soaking frequency

• This can be done 3–4 times daily when the anal area is painful or uncomfortable, or according to the frequency recommended by a doctor or healthcare professional.

• Sitz baths for hemorrhoids primarily aim to soothe symptoms and aid in anal hygiene; they do not replace treatment for the underlying cause of hemorrhoids. If experiencing severe pain, prolonged bleeding, or if symptoms do not improve, seek medical examination to determine the cause.

Part 1: How to take a simple sitz bath at home using a bathtub

Step 1: Clean the bathtub before soaking

Clean the bathtub before taking a sitz bath

• Before taking a sitz bath or performing anal immersion, thoroughly clean the bathtub to reduce dirt, soap residue, and microorganisms that could come into contact with the sensitive skin area.

• Use a cleaner suitable for the bathtub material and scrub all areas that will come into contact with water, especially the bottom and sides of the tub. It is not necessary to use chlorine-based cleaners if regular cleaning products meet the cleaning requirements.

Rinse off cleaner completely

1. After scrubbing, thoroughly rinse the bathtub with clean water to completely remove any remaining cleaner, residue, and cleaning products.

2. Only begin the sitz bath for hemorrhoids when the tub has been rinsed clean and there are no lingering odors or residues from cleaning chemicals. This is especially important because the irritated anal area can be more sensitive to chemicals.

3. Do not mix cleaning agents, especially chlorine-containing products with vinegar or acidic substances, as this can produce toxic gases.

Step 2: Take a sitz bath with sufficiently warm water

Adjust water level appropriately

• Fill the bathtub with warm water until the water level reaches about 7.5–10 cm (3–4 inches). This amount of water is usually sufficient to cover the anal area, genitals, and perineum when seated.

• No need to fill the tub completely. When taking a sitz bath for hemorrhoids, the goal is to immerse the affected area in water, while avoiding water waste and making temperature control easier.

Check temperature before soaking

1. The water should be warm and comfortable, not scalding. You can use your finger or test a small amount of water on sensitive skin, like your wrist, beforehand.

2. A temperature of about 40°C (104°F) is typically used for warm water anal immersion. Do not use excessively hot water, as it can cause burns or make the inflamed, irritated skin area more uncomfortable.

3. If you are being treated for hemorrhoids, anal fissures, or other anal conditions, prioritize your doctor's specific instructions. In some cases, healthcare professionals may recommend a cool sitz bath instead of warm water.

Notes when taking a sitz bath

• Comfort is more important than trying to maintain a specific temperature. If the water causes a burning sensation, pain, or discomfort in the anal area, stop and adjust the temperature.

• For a sitz bath for hemorrhoids, warm water primarily helps soothe symptoms. It should not be considered a method that can self-treat all causes of anal pain, itching, or bleeding.

Step 3: Only add salt when instructed by a doctor

Prioritize clean water for sitz baths

• When taking a sitz bath for hemorrhoids or anal immersion, clean warm water is usually sufficient to soothe the painful area, while also helping to relax and reduce discomfort.

• Do not arbitrarily add salt, medication, or other substances to the water simply because you think they will make the sitz bath more effective. Some substances can cause skin dryness, irritation, or worsen inflammation.

Only use additives as prescribed

• If your doctor instructs you to add salt or a treatment product to the water, use the correct type, amount, and method as directed.

• Before using any additives for anal immersion, consult your doctor or healthcare professional, especially if the skin is abraded, inflamed, or bleeding.

Do not mix homemade ingredients

• Common ingredients like salt, vinegar, baking soda, or essential oils are not inherently safe when they come into contact with the anal area. Adding them to sitz bath water for hemorrhoids does not always improve symptoms and can cause irritation.

• Unless specifically instructed, the simpler and safer option is to take a sitz bath with clean water at an appropriate temperature.

Step 4: A 10-20 minute sitz bath is sufficient

Sit in the correct posture to immerse the affected area in water

• Slowly sit into the bathtub filled with warm water, avoiding sitting down too quickly if the anal area is painful or sensitive.

• Adjust your posture so that the water covers the entire anal area, genitals, and perineum that need care. You can slightly bend your knees or lean your back against the tub to sit more comfortably.

Maintain appropriate soaking time

• Take a sitz bath for hemorrhoids for about 10–20 minutes. There is no need to soak longer to increase effectiveness, as prolonged water exposure can soften and irritate the skin.

• During the first few minutes, the painful or irritated area may still feel uncomfortable. However, this sensation usually subsides as the body adjusts to the warm water.

Keep the water at a comfortable temperature

• If the water cools down during anal immersion, you can add a suitable amount of warm water to maintain comfort.

• Do not use excessively hot water to compensate for temperature loss. If you experience burning, increased pain, dizziness, or unusual discomfort, stop the sitz bath and get out of the tub.

• If your doctor has instructed you to use cool water instead of warm water, adhere strictly to that instruction instead of adjusting to hot water yourself.

Step 5: Gently dry after soaking

Exit the bathtub carefully

• After a sitz bath for hemorrhoids, slowly stand up and step out of the tub. If you feel dizzy or lose balance, hold onto the side of the tub or ask for assistance.

• Especially after soaking in warm water for a relatively long time, do not stand up abruptly. Moving slowly helps reduce the risk of slipping, falling, or dizziness.

Pat dry the anal area, do not rub

• Use a clean, soft towel to gently pat dry the anal area, genitals, and perineum.

• Do not rub, scrub, or wipe vigorously after anal immersion, as the injured tissues can be very sensitive. Strong friction can increase irritation, inflammation, or cause burning pain.

Only apply medication as directed

• If your doctor has prescribed an ointment, cream, or instructed you to use gauze, apply it after the skin has been patted dry and exactly as directed.

• Do not arbitrarily apply creams, medications, or hygiene products to the anal area just because you have just finished a sitz bath, especially if you are unsure whether the product is suitable for your current condition.

Maintain appropriate frequency

• You can take a sitz bath for hemorrhoids 3–4 times daily or as recommended by your doctor, depending on the cause and severity of your symptoms.

• If pain, bleeding, or irritation does not improve, recurs, or worsens, seek medical attention instead of continuing self-care at home.

Part 2: Instructions for using a specialized sitz bath basin

Step 1: Clean the sitz bath basin before use

Clean the sitz bath basin properly

• If using a specialized sitz bath basin placed on the toilet, clean the basin before each use, even if it is new. This helps limit dust and bacteria from coming into contact with the anal area, especially when the skin is injured.

• Wash the basin with a cleaner suitable for its material, scrub all surfaces that will come into contact with water and the body, then rinse thoroughly with water to completely remove any cleaning product residue.

Check the kit before anal immersion

1. Some anal immersion kits come with a water bag, tubing, or accessories to deliver water to the affected area. Inspect and clean these parts according to the manufacturer's instructions.

2. If the kit requires mixing a solution into the water, only do so with clear instructions from the manufacturer or a healthcare professional. Do not arbitrarily add chemicals or medications to the sitz bath water for hemorrhoids.

Ensure the basin is clean but free of chemicals

• After cleaning, rinse thoroughly with clean water and check to ensure there is no residue or odor from cleaning agents before use.

• The anal and genital areas are quite sensitive. Therefore, the goal of cleaning the basin is to reduce the risk of contamination without allowing residual chemicals to come into contact with the skin.

Step 2: Assemble the sitz bath kit correctly

Thread and secure the water tube

• If the sitz bath kit includes a water bag and tubing, assemble the parts before adding water to the basin.

1. Thread the plastic tube connected to the water bag through the hole at the front of the sitz bath basin.

2. Pull the tube into the middle of the basin, then secure it to the clip at the bottom of the basin so that the tube does not move during anal immersion.

3. Recheck the connections to ensure the tube is securely attached and does not bend, twist, or come loose during use.

Follow the kit instructions

• The position of the tubing hole and securing clip may vary between different types of sitz bath kits for hemorrhoids. If you cannot determine the installation position, refer to the product's user manual instead of guessing how to assemble it.

• Before soaking, it is advisable to check the water flow and the stability of the basin to prevent leaks, dislodged tubing, or the basin shifting when seated.

Step 3: Place the sitz bath basin securely on the toilet

Place the basin in the correct position

• Open the toilet lid and seat, then place the sitz bath basin onto the toilet rim so that it sits evenly.

• Check the entire rim of the basin to ensure it makes stable contact with the toilet rim and is not tilted to one side.

Check for stability before soaking

• Gently press on the basin with your hand to check. The basin should not wobble, tilt, or slide when force is applied.

• Only begin anal immersion when the basin is stable. If the basin wobbles or does not fit the toilet, do not attempt to use it, as water may spill or the user may lose balance.

• If the kit comes with specific installation instructions, prioritize following the manufacturer's guidelines, as the design and securing methods may vary between different types of basins.

Step 4: Pour warm water into the sitz bath basin

Pour water into the basin or reservoir bag

• If the sitz bath kit consists only of a basin, pour warm water until it is deep enough to cover the perineal area, usually about 7.5–10 cm (3–4 inches) when seated.

• If the kit includes a reservoir bag and tubing, first move the flow control clamp to the "Off" position. Then, pour warm water into the bag to prevent water from flowing out during preparation.

Place the water bag higher than the basin

• Place the water reservoir bag on a table next to the toilet or hang it in a secure position, higher than the sitz bath basin. This height allows water to flow down into the basin through the tubing when the clamp is opened.

• Check the bag, tubing, and connections before anal immersion to prevent leaks or unintended water flow.

Check the water temperature

1. Use your finger to check the water before pouring it into the basin or bag. The water should be warm, comfortable, and not scalding.

2. A temperature of approximately 40°C (104°F) is typically used for a warm sitz bath for hemorrhoids. Do not use excessively hot water, as it can cause burns or make the irritated anal area more uncomfortable.

3. If your doctor instructs you to use cool water instead of warm water, adhere strictly to that instruction.

Only add solution when indicated

• If your doctor instructs you to add salt or a supportive solution to the water, use the correct type and amount as recommended.

• If there is no specific instruction, a sitz bath with clean water is the simpler option. Do not arbitrarily add salt, medication, or other ingredients with the aim of increasing the effectiveness of a sitz bath for hemorrhoids.

Step 5: Sit in the correct posture during a sitz bath

Sit into the sitz bath basin very carefully

• Slowly sit down into the sitz bath basin, adjusting your posture so that the anal area and perineum are comfortably immersed in the water.

• Do not sit down abruptly, especially when the anal area is painful, swollen, or sensitive. Ensure the basin is firmly secured on the toilet before sitting.

Open the water tube if your kit includes one

1. For a sitz bath kit with a bag and tubing, move the regulating clamp to the “Open” position to allow water to flow into the basin.

2. Water may flow through the tube and directly contact the perineal area before collecting in the basin, allowing the affected area to be immersed in water.

3. If the stream of water is uncomfortable, move the clamp to the “Closed” position, remove the tube end from its fixed position at the bottom of the basin, and let the tube rest inside the basin. This way, water will flow into the basin instead of spraying directly onto the skin.

Adjust if you feel pain or discomfort

• During the first few minutes of a sitz bath for hemorrhoids, some people may experience slight pain or stinging as the affected area comes into contact with water. This sensation may gradually subside after a few minutes.

• However, if the pain, burning, or irritation increases instead of decreases, stop the sitz bath, check the water temperature, and the condition of the skin being treated.

• Do not endure pain caused by the water jet. The goal of a sitz bath is to provide comfort and help alleviate symptoms, not to cause further irritation to the affected area.

Step 6: Soak in water for 10–20 minutes

Soak for enough time to relieve discomfort

• If using a sitz bath kit with a water bag and tube, slowly open the clamp to allow water to flow into the basin until the anal and perineal areas are in contact with the water.

• Soak for approximately 10–20 minutes. This duration can help soothe pain, burning, and discomfort in the anal area, while also assisting in cleaning the irritated area.

• There is no need to soak longer with the expectation of increasing the effectiveness of a sitz bath for hemorrhoids. Care should focus on comfort and avoiding further skin irritation.

Maintain a comfortable water temperature

• During a sitz bath, if the water cools and becomes uncomfortable, you can add a suitable amount of warm water to maintain a pleasant temperature.

• Do not use excessively hot water to rewarm the basin. Hot water can cause burns or further irritate the already damaged anal area.

Monitor the water level in the basin

• When adding water, do so slowly to prevent overflow. Some sitz bath basins have a drain slot at the back, allowing excess water to flow into the toilet.

• Before sitting, ensure the basin is securely and stably placed. Throughout the soaking process, if increased pain, burning, or unusual discomfort occurs, stop rather than continue.

Step 7: Gently pat dry after a sitz bath

Stand up and get out of the basin slowly

• After a sitz bath for hemorrhoids, slowly stand up from the basin. If you feel dizzy or lightheaded, hold onto a sturdy surface nearby or ask someone for assistance to avoid losing balance.
