As handmade bath product creators at Coorong Candle Co., we spend a lot of time thinking about what goes into a good soak, from ingredients to scent profiles to how your skin feels afterwards. So when customers ask us about Kmart bath salts, we get it. Not everyone wants to splurge on artisan products for their Tuesday night bath, and Kmart has built a surprisingly solid range of affordable options worth knowing about.
Whether you're after Epsom salts for sore muscles, magnesium blends for relaxation, or something that just smells great and fizzes a little, Kmart's bath salt lineup covers more ground than most people realise. The challenge is figuring out which ones are actually worth your money and which are better left on the shelf. That's where having some product knowledge helps.
In this guide, we've rounded up 12 Kmart bath salts currently available across their stores and online. For each one, we'll break down the key ingredients, what they're best suited for, and who they'll appeal to most, so you can pick the right product without the guesswork.
1. Kmart Epsom Bath Salts 750g - Lavender and Lemongrass
This is the most recognised Kmart bath salts option in the range, and for good reason. The lavender and lemongrass combination gives you a scent that leans relaxing without being overpowering, which makes it a reliable go-to for everyday use rather than just occasional treats.
What it is
Kmart's Epsom Bath Salts in Lavender and Lemongrass are a magnesium sulphate-based soak blended with fragrance oils from lavender and lemongrass botanicals. The 750g tub gives you around 8 to 10 full baths depending on how much you use per soak, and the medium-coarse salt granules dissolve well in warm water without leaving clumps at the bottom of the tub.
The formula skips artificial colourants, so the salts appear natural off-white rather than dyed. There are no synthetic dyes or unnecessary fillers, which keeps it accessible for people who prefer straightforward, functional products without a complicated ingredient list to parse.
Best for
This blend suits anyone looking to unwind after a long day or settle down before bed. Lavender has well-documented associations with relaxation and stress reduction, while lemongrass adds a light citrus lift that stops the scent from feeling too heavy or clinical on the nose.
If you find heavily perfumed bath products irritating, the scent level here is moderate, making it a reasonable choice for those with mild fragrance sensitivity.
The 750g size also makes this a strong pick for regular, daily bathers who want value for money without paying premium prices. The cost per bath works out low, which matters when bathing is part of your daily routine rather than an occasional splurge.
How to use it
Pour one to two large handfuls into a warm running bath so the salt dissolves evenly and the fragrance releases properly before you get in. If you prefer a stronger scent experience, add a little more, but the standard amount gives you a solid starting point without overwhelming the room.
Soak for at least 15 to 20 minutes to let your skin and muscles absorb the magnesium sulphate properly. Avoid water that's too hot, as extreme heat causes fragrance to dissipate quickly and can leave your skin feeling dry after. Pat your skin dry rather than rubbing, particularly if you have sensitive skin, to keep moisture locked in.
Price and size guide
The Kmart Epsom Bath Salts 750g in Lavender and Lemongrass typically retails between $5 and $8 AUD, placing it firmly at the affordable end of the market. You get a generous amount of product for that price, which is one of the main reasons it sells consistently across both in-store and online channels.

2. Kmart Epsom Bath Salts 750g - Rose and Geranium
The rose and geranium variant sits alongside the lavender option as one of the more popular kmart bath salts in the Epsom range. It carries a distinctly floral character that appeals to anyone who prefers warmer, more romantic scents over citrus-forward or herbal alternatives.
What it is
Kmart's Epsom Bath Salts in Rose and Geranium use the same magnesium sulphate base as the rest of the Epsom range, blended with rose and geranium fragrance to create a softer, more floral bathing experience. The 750g tub and medium-coarse salt texture are consistent with the other variants, so the granules dissolve cleanly in warm water without leaving residue.
Geranium adds an earthy, slightly herbal edge that balances the sweetness of rose and keeps the overall scent from going too powdery or artificial-smelling. That nuance makes this blend more interesting than a basic single-note floral product.
Best for
This blend works well for anyone who finds floral scents comforting and grounding. Rose and geranium both appear in aromatherapy for their association with emotional balance and mood support, which makes this a solid pick when you want something that feels more nurturing than a citrus or sharp herbal option.
If you tend to find rose-scented products too sweet or synthetic, the geranium cuts through that and gives the blend a more balanced, natural finish.
How to use it
Add one to two generous handfuls into a warm running bath and let the salt dissolve fully before you step in. The floral fragrance releases best in water between 37°C and 40°C, warm enough to carry the scent without drying out your skin.
- Soak for at least 15 minutes to get the most from the magnesium sulphate
- Pat your skin dry rather than rubbing to hold in moisture after your bath
Price and size guide
The rose and geranium variant is priced in line with the rest of the Epsom range, making it easy to try without committing to a significant spend upfront.
| Detail | Specification |
|---|---|
| Size | 750g |
| Approximate uses per tub | 8 to 10 baths |

3. Kmart Epsom Bath Salts 750g - Pink Grapefruit and Nectarine
The pink grapefruit and nectarine variant brings a brighter, more uplifting energy to the kmart bath salts Epsom range. Where lavender calms and rose nurtures, this one wakes you up, making it the obvious pick for morning baths or midday resets rather than wind-down soaks before bed.
What it is
Kmart's Epsom Bath Salts in Pink Grapefruit and Nectarine use the same magnesium sulphate base as the rest of the Epsom line, but the fragrance profile here is citrus-forward and fruity rather than floral or herbal. The 750g tub holds medium-coarse granules that dissolve cleanly in warm water, and the scent carries a sharp, juicy quality that fills the bathroom quickly once the salt hits the water.
Nectarine adds a soft, sweet undertone that keeps the grapefruit from going too tart or sharp. That balance makes the blend more approachable than a straight citrus product, which can sometimes read as cleaning product rather than bath soak.
Best for
This blend suits morning bathers who want their bath to feel energising rather than sedating. Citrus scents are widely associated with improved alertness and mood lift, so if you find lavender or floral options too sleepy for a pre-work soak, this variant gives you the same Epsom salt benefits in a scent that actually suits the time of day.
This is also a strong option for warmer months when heavier floral scents can feel stuffy and a lighter, fresher profile sits better.
How to use it
Add one to two handfuls to a warm running bath and let the salt dissolve before stepping in. Because citrus fragrance dissipates faster than floral or herbal scents in heat, keep your water temperature moderate rather than hot to hold the scent longer. Soak for at least 15 minutes to get full value from the magnesium sulphate.
Price and size guide
This variant sits at the same price point as the rest of the range.
| Detail | Specification |
|---|---|
| Size | 750g |
| Approximate uses per tub | 8 to 10 baths |
| Price range | $5 to $8 AUD |

4. Kmart Magnesium Bath Salts 650g
The Kmart Magnesium Bath Salts sit in a slightly different category from the Epsom range. While Epsom salts are magnesium sulphate, these are formulated with magnesium chloride, which many people consider more bioavailable, meaning your skin may absorb it more readily during a soak.
What it is
The Kmart Magnesium Bath Salts come in a 650g tub and are unfragranced or lightly scented depending on the batch, making them one of the more straightforward options across the kmart bath salts range. The granules are slightly finer than the Epsom variants, which means they dissolve faster in warm water and require less stirring to fully break down. The formula focuses on functional bathing rather than fragrance experience, so if you prefer your bath products to do a job without a strong scent, this one sits in the right lane.
Best for
This product works well for people who prioritise muscle recovery and relaxation over scent. Magnesium chloride is a popular choice among athletes, people with physically demanding jobs, and anyone who experiences tension or restlessness in their body at the end of the day.
If you have sensitive skin or react to added fragrance, the minimal-scent formulation makes this a safer starting point than most of the other options in the range.
How to use it
Add two to three large handfuls into a warm bath and give the water a brief stir to help the salts dissolve fully before you get in. Soak for 20 minutes minimum to allow adequate skin contact time. Rinse off lightly afterwards if your skin tends to feel sticky, which is common with magnesium chloride products.
Price and size guide
This tub is competitively priced given its focus on functional magnesium delivery rather than premium fragrance blending.
| Detail | Specification |
|---|---|
| Size | 650g |
| Approximate uses per tub | 6 to 8 baths |
| Price range | $6 to $9 AUD |
| Available in-store | Yes |
| Available online (kmart.com.au) | Yes |
5. Epzen Relax Magnesium Epsom Salts 900g
The Epzen brand represents a step up within the kmart bath salts lineup. While it sits on the same shelves as Kmart's own-label options, Epzen operates as a dedicated bath and body brand with a stronger focus on therapeutic formulation rather than basic fragrance and salt combinations.
What it is
Epzen Relax Magnesium Epsom Salts come in a 900g tub, making it one of the larger sizes available in the range. The formula combines magnesium sulphate with a calming essential oil blend, typically built around lavender, to create a product that bridges the gap between a functional recovery soak and a more indulgent bathing experience.
The granule texture is medium-coarse and dissolves readily in warm water. The Epzen packaging is also more considered than Kmart's own-label tubs, which makes it a reasonable option if you're buying a bath product as a gift rather than just for yourself.
The 900g size gives you noticeably more product per tub than most other options in the range, which matters if you bathe regularly and don't want to restock every few weeks.
Best for
This product works best for people who want consistent magnesium delivery alongside a proper scent experience rather than one or the other. The relaxation-focused blend suits evening bathers who use their bath as part of a wind-down routine, and the larger tub size suits regular use rather than occasional soaks.
How to use it
Add two generous handfuls to a warm running bath and let the salts dissolve before you get in. Soak for at least 20 minutes to allow the magnesium to work effectively. Keep the water temperature between 37°C and 40°C so the essential oil fragrance lasts through your soak rather than burning off quickly.
Price and size guide
The Epzen Relax Magnesium Epsom Salts sit at a slightly higher price point than Kmart's own-label equivalents, reflecting the brand positioning and larger tub size.
| Detail | Specification |
|---|---|
| Size | 900g |
| Approximate uses per tub | 10 to 12 baths |
| Price range | $9 to $12 AUD |
| Available in-store | Yes |
| Available online (kmart.com.au) | Yes |
6. Epzen Soothe Magnesium Epsom Salts 900g
The Epzen Soothe variant sits alongside the Relax version as one of the more refined options within the kmart bath salts range. Where Relax leans toward lavender-driven calm, Soothe takes a different approach, using a eucalyptus and peppermint-forward blend that targets physical discomfort more directly than most other options on this list.
What it is
Epzen Soothe Magnesium Epsom Salts come in a 900g tub and combine magnesium sulphate with cooling botanical extracts, typically eucalyptus and peppermint, to create a soak that feels noticeably different from the standard floral or citrus alternatives in the range. The granules are medium-coarse and dissolve well in warm water, releasing a sharp, mentholated scent that fills the bathroom quickly and lingers for the duration of your soak.
The eucalyptus and peppermint combination gives this product a spa-like quality that most budget bath salts simply don't deliver.
Best for
This blend works well for people who carry tension in their muscles after physical activity, long working hours, or time spent on their feet. The cooling nature of peppermint and the decongestant properties of eucalyptus make this a practical pick when you want your bath to feel actively therapeutic rather than purely relaxing.
People who enjoy a sharper, more invigorating scent profile over florals will also find this more satisfying than the lavender-dominant options available from both Epzen and Kmart's own label range.
How to use it
Add two large handfuls to a warm running bath and allow the salts to dissolve fully before stepping in. Keep your water at a moderate temperature since the eucalyptus fragrance fades faster in very hot water. Soak for 20 minutes to get the most from the magnesium content.
Price and size guide
The Soothe variant is priced in line with the Epzen Relax, reflecting the same 900g tub size and brand positioning within the Epzen range.
| Detail | Specification |
|---|---|
| Size | 900g |
| Approximate uses per tub | 10 to 12 baths |
| Price range | $9 to $12 AUD |
| Available in-store | Yes |
| Available online (kmart.com.au) | Yes |
7. OXX Bodycare Sprinkle Bath Salts 650g - Watermelon
The OXX Bodycare range represents a different direction within the kmart bath salts lineup. These products prioritise fun, fruity fragrance over therapeutic function, which makes them a practical choice when you want a bath that's enjoyable and uplifting rather than recovery-focused.
What it is
OXX Bodycare Sprinkle Bath Salts in Watermelon come in a 650g tub with a lighter salt base than the Epsom or magnesium chloride options elsewhere in the range. The granules are finely milled, which means they dissolve almost immediately in warm water rather than requiring any stirring or waiting. The watermelon fragrance is bold and sweet from the moment you open the tub, leaning into a playful, summery character that sets it apart from the more functional options on this list.
If you prefer your bath to feel like a treat rather than a recovery session, the OXX Bodycare range makes a strong case for itself.
Best for
This product suits younger bathers or anyone who enjoys bright, fun scent profiles over the more traditional lavender and eucalyptus options. It also works well as a gift for teenagers or as a fun addition to a gift basket alongside candles or soaps. Because the formulation focuses on fragrance rather than therapeutic mineral content, it is a better fit for people seeking an enjoyable sensory experience than those looking for muscle recovery or sleep support.
How to use it
Pour one to two handfuls directly into a warm running bath and watch the salts dissolve quickly. The watermelon scent carries well at moderate water temperatures, so avoid filling your bath too hot or the fragrance will fade before you even step in. Soak for as long as you like since this product is more about the experience than a timed mineral absorption process.
- Use a smaller amount for a lighter scent
- Add more if you want a stronger fragrance hit
Price and size guide
The OXX Bodycare Sprinkle Bath Salts sit at the more affordable end of the range given their lighter formulation and fragrance-forward focus.
| Detail | Specification |
|---|---|
| Size | 650g |
| Approximate uses per tub | 8 to 10 baths |
| Price range | $5 to $7 AUD |
| Available in-store | Yes |
| Available online (kmart.com.au) | Yes |
8. OXX Bodycare Sprinkle Bath Salts 650g - Grapefruit
The grapefruit variant of the OXX Bodycare Sprinkle Bath Salts offers a sharper, more energising take on the same fun, fragrance-first formula as the watermelon option. If you find tropical-sweet scents a bit much, this one gives you citrus brightness without veering into candy territory.
What it is
OXX Bodycare Sprinkle Bath Salts in Grapefruit come in a 650g tub with the same finely milled salt base found across the OXX Bodycare range. The granules dissolve quickly in warm water, releasing a clean, zesty grapefruit fragrance that reads fresh and uplifting rather than overly sweet. Like the watermelon version, the formulation focuses on scent experience rather than therapeutic mineral content, so you get a light and enjoyable soak rather than a recovery-focused product.
The grapefruit scent here lands noticeably closer to a fresh-squeezed citrus note than a synthetic candy interpretation, which makes it more versatile across different age groups and preferences.
Best for
This variant works well for people who want their bath to feel energising and refreshing rather than sedating. Grapefruit is a popular choice in morning routines because citrus scents are widely associated with alertness and mood uplift, making this a solid option if you prefer a bath at the start of the day rather than the end. It also suits anyone who finds lavender or floral options in the kmart bath salts range too heavy for regular use.
How to use it
Pour one to two handfuls into a warm running bath and let the salts dissolve on their own since the fine granules break down fast without any stirring. Keep your water temperature moderate to preserve the citrus fragrance, as grapefruit dissipates quickly in very hot water. Soak for as long as you like, then rinse off lightly if needed.
- Use less for a subtle background scent
- Add more for a stronger citrus hit that carries through the room
Price and size guide
The grapefruit variant sits at the same price point as the rest of the OXX Bodycare Sprinkle range.
| Detail | Specification |
|---|---|
| Size | 650g |
| Approximate uses per tub | 8 to 10 baths |
| Price range | $5 to $7 AUD |

9. OXX Bodycare Sprinkle Bath Salts 650g - Strawberry
The strawberry variant completes the OXX Bodycare Sprinkle Bath Salts trio available across the kmart bath salts range. It carries the sweetest, most dessert-like scent of the three OXX options, which makes it the most distinctive in terms of character and the most likely to split opinion based on your personal scent preferences.
What it is
OXX Bodycare Sprinkle Bath Salts in Strawberry come in a 650g tub with the same finely milled salt base used across the OXX Bodycare Sprinkle range. The granules dissolve quickly in warm water without any stirring, releasing a sweet, candy-leaning strawberry fragrance that fills the bathroom fast. Like the watermelon and grapefruit versions, the formulation prioritises fragrance enjoyment over therapeutic mineral delivery, so this is a product built around the bathing experience rather than muscle recovery or sleep support.
The strawberry scent sits firmly in sweet, fun territory rather than attempting a realistic fruit note, which works in its favour if you enjoy indulgent, playful bath products.
Best for
This variant works best for younger bathers or anyone who enjoys bold, sweet fragrance as part of their self-care routine. It makes a strong addition to gift sets or gift baskets for teenagers and younger adults who find the herbal and floral options in the range too grown-up or dull. Because the formula leans entirely into fragrance rather than therapeutic function, it suits people who want their bath to feel like a treat rather than a recovery tool.
How to use it
Pour one to two handfuls into a warm running bath and let the finely milled salts dissolve on their own. Keep your water temperature moderate rather than hot so the strawberry fragrance carries through your full soak. Soak for as long as suits you since there is no timed mineral absorption process to follow with this product.
Price and size guide
This variant is priced in line with the rest of the OXX Bodycare Sprinkle range, keeping it accessible for regular use.
| Detail | Specification |
|---|---|
| Size | 650g |
| Approximate uses per tub | 8 to 10 baths |

10. Kmart bath salts and soaks section online
Beyond individual products, Kmart's dedicated bath salts and soaks section on kmart.com.au gives you a single place to browse the full range, compare options side by side, and check current stock availability at your nearest store before making the trip. It operates as a useful tool in its own right, particularly when the product you want might be sold out locally.
What it is
The kmart bath salts and soaks section on kmart.com.au is a filtered product category page that pulls together every bath salt, Epsom soak, and magnesium blend stocked across Kmart's Australian locations and distribution network. You can browse by price, brand, or fragrance type, and the page updates regularly to reflect seasonal additions and clearance lines that don't always make it to every physical store. It covers Kmart's own-label Epsom and magnesium ranges, the Epzen line, and the OXX Bodycare Sprinkle salts.
Checking the online section before heading in-store saves you from discovering that the specific variant you want is out of stock on arrival.
Best for
This online section suits anyone who prefers to research before buying or who lives further from a major Kmart location and relies on delivery. It also works well when you want to compare the full range in one sitting without walking the aisles or asking staff. Click and collect is available on most lines, which combines the convenience of browsing online with same-day pickup if stock is confirmed at your local store.
How to use it
Navigate to kmart.com.au and use the search bar or the health and beauty category to find the bath salts and soaks section. Filter by price range or brand to narrow your results quickly. Add your preferred products to your cart and select delivery or click and collect at checkout based on your location and urgency.
Price and size guide
Prices across the online section match in-store pricing, so you won't pay more for the convenience of browsing digitally. Delivery fees apply for orders under the free shipping threshold, which varies by promotion period, so checking the current minimum at checkout before finalising your order is worthwhile.
11. Kmart bath salts for better sleep
If you struggle to wind down at the end of the day, adding bath salts to your evening routine can make a genuine difference. The right product here isn't about the most expensive option in the range or the most elaborate formula. It comes down to picking the correct scent profile and magnesium type to support your body's natural shift toward rest.
What it is
The best kmart bath salts for sleep support are the lavender-forward options from both Kmart's own-label Epsom range and the Epzen Relax tub. Lavender has well-documented associations with reducing anxiety and supporting sleep onset, and pairing that fragrance with magnesium sulphate gives you a soak that works on two levels. The magnesium helps your muscles release tension while the scent signals to your nervous system that it's time to slow down.
The Epzen Relax 900g tub is the stronger recommendation here because it delivers a more concentrated essential oil blend alongside a larger magnesium dose per soak than the Kmart own-label Epsom tubs.
Best for
This approach works best for people who struggle to switch off after physically or mentally demanding days. If your sleep difficulty comes from a racing mind or physical restlessness rather than a diagnosed condition, a warm magnesium bath about 60 to 90 minutes before bed sits within your own bedtime routine as a practical, low-cost intervention.
How to use it
Run a warm bath between 37°C and 40°C and add two generous handfuls of your chosen lavender-scented salt. Soak for at least 20 minutes rather than rushing. Keep your phone out of the room and dim the bathroom lights if possible. The temperature drop your body experiences after leaving the warm water actively signals your brain to initiate sleep, so timing your soak correctly matters as much as the product itself.
Price and size guide
You can build a solid sleep-focused bathing routine for well under $15 AUD using products already covered in this list, with the Epzen Relax sitting at the higher end and Kmart's own Epsom Lavender and Lemongrass tub at the lower end.
| Product | Size | Price range |
|---|---|---|
| Kmart Epsom Lavender and Lemongrass | 750g | $5 to $8 AUD |
| Epzen Relax Magnesium Epsom Salts | 900g | $9 to $12 AUD |
12. Kmart bath salts for sore muscles after exercise
Post-exercise recovery is one of the most practical reasons people reach for bath salts in the first place. Rather than spending money on specialist sports recovery products, the right option from the kmart bath salts range does the job at a fraction of the price.
What it is
The best options for muscle recovery in the Kmart range are the magnesium-based products, specifically the Kmart Magnesium Bath Salts 650g and the Epzen Soothe 900g. Both deliver meaningful magnesium content per soak, and the Epzen Soothe adds eucalyptus and peppermint to the mix, which gives your bath a cooling quality that complements post-exercise muscle soreness particularly well. The Kmart own-label magnesium tub works better if you prefer a minimal-scent option that lets the magnesium do its job without a strong fragrance alongside it.
Best for
This approach suits anyone who trains regularly, whether that is running, gym sessions, sport, or manual work that leaves your legs or back tight at the end of the day. Magnesium applied through the skin during a warm bath is a practical and accessible way to support muscle recovery between sessions, and it costs significantly less than magnesium supplement tablets or specialist recovery products from sports stores.
The Epzen Soothe is the stronger pick if your soreness is concentrated in specific muscle groups, as the eucalyptus and peppermint create a noticeably cooling sensation that makes the soak feel actively targeted rather than passive.
How to use it
Run a warm bath and add two to three large handfuls of your chosen magnesium salt. Avoid very hot water since extreme heat can increase inflammation rather than reduce it. Soak for at least 20 minutes to allow proper skin contact time. Rinse off lightly afterwards if the magnesium leaves your skin feeling sticky.
Price and size guide
Both recommended products are well under $12 AUD, making this a genuinely affordable recovery tool compared to alternatives.
| Product | Size | Price range |
|---|---|---|
| Kmart Magnesium Bath Salts | 650g | $6 to $9 AUD |
| Epzen Soothe Magnesium Epsom Salts | 900g | $9 to $12 AUD |
Quick recap
The kmart bath salts range covers more ground than most people expect for the price. If you want therapeutic magnesium delivery, the Epzen Soothe or Epzen Relax tubs give you the most per soak. For a scented everyday option, Kmart's own Epsom range in lavender, rose, or grapefruit all do the job reliably. The OXX Bodycare Sprinkle salts suit anyone after a fun, fragrance-first experience rather than a recovery focus.
Your best starting point is matching the product to your actual goal, whether that's winding down before sleep, easing sore muscles after exercise, or simply making your bath more enjoyable. Use the online section at kmart.com.au to confirm stock before heading in-store, and check back regularly since the range shifts with season and availability.
