What’s a good price for bath & soak?

How to land in the good-price band

Bath products are bought by the bottle and poured by the capful, so cost per fl oz is the figure that matters — and a boutique bath oil can cost 20× a drugstore bubble bath for the same few minutes in the water.

• •Buy the big bottle and pour less. Most bath oils and soaks are dosed at a capful; the "luxury" instinct to pour generously is what makes them expensive per use. A large bottle used sparingly beats a small one every time on cost per oz.
• •Plain Epsom salt is the cheapest soak by a wide margin. The magnesium-sulfate part is a few cents an ounce in bulk; a scented "bath soak" is Epsom salt plus fragrance at 10–30× the price. Buy the bulk salt and add a few drops of essential oil.
• •A scented bath oil is a perfume purchase — price it that way. Cult bath oils cost per oz what a fragrance does, because that is largely what they are. Worth it for the ritual, but judge them against perfume, not against soap.
• •Bubble bath and shower gel overlap; the cheaper per oz wins for both. A good body wash foams fine under a running tap, so you rarely need a separate bubble bath — compare the two on cost per fl oz and keep whichever is cheaper.
