I’m not sure the product is called “bubble bath”, but the real name escapes me!
I’m having a rare bath and was struck, not really knowing how much of the Radox to add!
I’m a frugal person generally. I serve one baggie of microwave rice to two people, for example (a previous thread).
My DF would add almost all of a LITRE bottle to his baths when I lived with my parents.
I went with about half of the 500ml bottle, which felt a bit extravagant.
How much do you add?
