"Smells divine and you literally float out and into bed. The best!"
Sam ⭐⭐⭐⭐⭐
Mind still racing when everything else has stopped?
Onsen is our tribute to Japan's traditional hot springs, where water, nature and silence meet. It's a 20-minute mineral bath ritual that helps quiet a busy mind and bring you back to stillness.
5 hot spring soaks in every bottle. Just $13.99 per bath.
Why it works
- Magnesium absorbs through your skin. Your body takes in what it needs while you do nothing. No pills, no powders, no aftertaste.
- Hinoki and yuzu help you find your calm. The grounding woodiness of Japanese cypress meets the bright citrus warmth of yuzu. Clean, calming and never synthetic.
- Made for the onsen ritual. Slow down, breathe in the steam and let the warm, mineral-rich water hold you.
- 20 minutes is all it takes. Pour. Soak. Breathe. You'll feel it before you finish drying off.
Measure 100 mL with ease using our Bath Tonic Measuring Cup.
A 20-minute soak inspired by Japan's hot springs. It helps:
• Quiet a busy mind
• Ground you with hinoki and yuzu
• Ease tired muscles
• Soften and hydrate your skin
Bath
Add 100 mL to warm, swirling water. Remove jewellery, slip in and relax for at least 20 minutes.
To enhance your experience, decant 100 mL into a small bowl, add a small amount of warm water (1 tbs) and swirl it gently. Pour the contents into the tub, and as you do, take three deep breaths, savouring the moment as the white mineral cloud gracefully envelops the clear water.
Foot bath
Add 30 mL into 5 L warm, swirling water. Immerse feet, relax and enjoy for at least 20 minutes.

WHAT OUR CUSTOMERS ARE SAYING
Soothing and relaxing! Another excellent quality product that smells refreshing and feels so good for my body and mind. Getting my friends on to it!!!
I love Onsen. Smells devine and you literally float out and into bed. The best!
Bought this for my daughter, because on our recent trip to Japan. She braved the public Onsen at our hotel. I asked her after she tried the Onsen Magnesium Bath Tonic, did it smell the same. She said yes. So if you want your very own private Onsen experience. Give it a go!
Cute little bottle l gifted to my daughter to enjoy a long soak after working all day
Just ordered my 2nd bottle because the ONSEN bath tonic is an absolute favourite! It’s beautifully relaxing, leaves my skin super soft & I sleep incredibly well after a bath. I use the ceramic measuring cup from 39 degrees. I book my baths in like any other essential appointment and it’s always worth it!
