WHAT OUR CUSTOMERS ARE SAYING
Best sleep ever after this relaxingly pampering bathing experience.
Absolutely delicious. Such a calming aroma and silky feel.
I have never lived anywhere without a bath and have had ritual baths throughout my whole adult life. You have provided me with 'at home' next level bathing that adds further health benefits and luxury. Thank you. X
I just love soaking in the bath with this tonic. I have loads of aches and pains in my back and I can feel it easing the moment I touch the water.
I have not come across any of your bath tonics that have not been great. I love just soaking in the bath with the tonics. We have been away on a road trip around nsw and I made sure we had enough bath tonics to last us while we were away.
