How much bath salt should I use per soak and what water temperature works best?

For a typical home bathtub (150–180 litres), 100–200 g of the Jordanian crystals is a practical starting point — enough to make the water feel noticeably mineral-rich without leaving a heavy residue. If your tub is smaller or you prefer a lighter soak, start with 80–100 g and adjust next time.

Water temperature should be comfortably warm, around 36–39 °C. Very hot water increases transepidermal water loss and can leave skin feeling tighter afterward, which defeats the softening purpose of the minerals. The source notes that warmth, buoyancy, and uninterrupted rest time are the three factors that make the soak restorative, so aim for a temperature you can stay in for the full 15–20 minutes without overheating.

Dissolve the salt completely before stepping in; stirring with your hand or a bath scoop helps the dense Jordanian crystals disperse evenly. After soaking, rinse briefly with lukewarm water and pat skin dry — leaving a faint mineral film is fine for most people, but rinsing removes any excess salt that could feel gritty once dry.
