Short answer: for most new moms in Canada, the best postpartum sitz bath soak is a salt blend that pairs Epsom salt with Dead Sea salt and gentle botanicals, so one bag works in a portable sitz basin and in the tub. Plant of Life Post Partum Sitz Bath Salt does exactly that, with organic oils and herbs and no preservatives on the ingredient list.
If price per soak is all you care about, Lansinoh and Peas in a Pod are cheaper. Here are the real numbers.

How we compared
We compared label facts and prices only: full ingredient lists, bag size, price per 100 g, and the number of soaks per bag where the brand states it. Prices were checked October 28, 2026 on Well.ca, Amazon.ca and plantoflifeco.com, in Canadian dollars. We also checked Frida Mom, Bodily and The Honest Company. None of the three lists a sitz soak on its own store right now (Frida Mom sells peri bottles, healing foam and cooling liners instead), so they are not in the table.

Best overall: Plant of Life Post Partum Sitz Bath Salt
This is the fullest ingredient list in the table: Epsom salt, Dead Sea salt, MSM, organic MCT coconut oil, organic sweet almond oil, organic sesame oil, organic white oak bark, aloe vera, organic nettle leaf and lavender oil. No preservatives appear on the list.
One 454 g bag gives about 5 to 7 soaks in a portable sitz basin (60 to 80 g each) or about 3 tub sitz baths (125 g each). It is $23.99, or $21.59 with Subscribe and Save, rated 4.92 out of 5 from 26 reviews, and it ships from a Canadian brand in 2 to 5 business days.
Lowest cost per soak: Lansinoh
Lansinoh is the value pick if you plan to soak every day. The 10 oz bag is $14.99 on Well.ca, and Lansinoh says it makes up to 20 sitz baths at 1 to 2 tablespoons each. That is about 75 cents a soak, far below anything else here.
The trade off is the formula. Alongside Epsom salt, aloe, frankincense, lavender and calendula, the list includes water, glycerin and two preservatives, potassium sorbate and sodium benzoate. Fine for many moms, but not the "just salts and plants" bag some people want.
Best herbal sachets: Earth Mama
Earth Mama is a different style of product. You brew six sachets of organic herbs like tea, cool the liquid and use it in your sitz basin. The herbs are certified by Oregon Tilth and the box is Non-GMO Project Verified. The ingredients are sea salt, organic oatmeal, witch hazel leaf, yarrow, plantain and calendula.
A bonus moms love: the brewed sachets can double as a cool pad, and the extra liquid can go on a pad for padsicles. It is $14.99 for six uses on Well.ca, about $2.50 a soak.
Best budget salt: Peas in a Pod
Peas in a Pod is a Canadian brand, and its Sittin' Pretty Perineal Salts are the cheapest per gram in our table: 625 g for $20.99, about $3.36 per 100 g. The list is short: Epsom salt, baking soda, cucumber extract, lavender, Roman chamomile, peppermint and tea tree oils, some of organic origin. There is no Dead Sea salt and no carrier oils, so expect a simpler soak.
Also on Amazon.ca
Fivona is a budget Epsom blend at $14.71 for 400 g, or $3.68 per 100 g. Pure Body Naturals has the most ratings in our list (4,036 on Amazon.ca) but is the priciest salt at $13.07 per 100 g. Matter Company, another Canadian brand, sells a pure herb blend of certified organic calendula, comfrey, lavender, rosemary, rose and yarrow, but at $18.99 for 85 g it is the most expensive per gram.
What to look for when buying
- Read the full ingredient list. Some "natural" soaks include water, glycerin and preservatives. Salts and dried botanicals should not need them.
- Salt base. Epsom salt is the standard. A blend with Dead Sea salt adds a wider mix of minerals.
- Works in a portable basin. Check the label gives a dose for an over the toilet sitz basin, not only a full tub.
- Soaks per bag. Divide the bag by the label dose. A cheap small bag can run out in the first week.
- Gentle scent. Lavender and chamomile are common. Strong mint or tea tree can feel intense on sensitive skin.
FAQ
What is the best sitz bath soak after birth?
Look for an Epsom salt base with a short list of gentle botanicals and no preservatives. Plant of Life combines Epsom salt, Dead Sea salt, MSM, organic oils and organic herbs in a 454 g bag. If you want the lowest cost per soak, Lansinoh makes up to 20 sitz baths per 10 oz bag. For a herbal tea style soak, Earth Mama is the classic.
How much sitz bath salt do I use?
Follow your bag. Plant of Life suggests 60 to 80 g for a portable sitz basin, or 125 g in the tub, then a 15 to 20 minute soak. Lansinoh suggests 1 to 2 tablespoons in a sitz basin or a cup in the bathtub. Peas in a Pod suggests up to half a cup in the bath.
Can I use plain Epsom salt for a postpartum sitz bath?
Many moms do, and plain Epsom salt is the base of almost every soak in our table. A blended soak adds things plain Epsom salt does not have, such as Dead Sea salt, calming lavender, plant oils for softer skin, and herbs like nettle or calendula. You are paying for the blend and the convenience of one ready bag.
When can I take a sitz bath after giving birth?
Plant of Life's directions say to wait a minimum of 3 days after delivery before a bath, and note that water on sensitive areas may sting at first before settling. Many moms start with a portable sitz basin over the toilet because it is easier than climbing in and out of a tub.
How long should a sitz bath be?
Most labels in our table say 15 to 20 minutes. Plant of Life says soak for 15 to 20 minutes and pat dry with a clean towel, and notes it may be used daily. Lansinoh also says 15 to 20 minutes, once daily or as desired. For a stronger soak, Plant of Life suggests using less water.
