The right temperature depends on you and on the product’s instructions. Read the bath salt label before you run the water. Hotter water does not make the product work better.
Keep the water comfortable and get out if you feel too hot, dizzy or unwell. The strength of the scent varies with the temperature, the ventilation and the amount used; it is no guide to safety.
A bath thermometer lets you check the temperature. Mix the water well to avoid hot spots and dissolve the product as directed. Keep to the time stated on the label.
With children, use only a product suitable for their age and follow all its specific instructions. Measure the temperature and stay within arm’s reach for the whole bath. Do not add essential oils or any other product to a Baby SPA bath.
