Think of your tub as an oasis. A place of privacy, serenity and pure indulgence. Now think of an essential product that can help transform your tile or glass enclosure into, well, pretty much heaven (at least for half an hour). Bath salts, grains, bubbles, foams, gels, teas and a bevy of other suds serve one common purpose: to make you the queen (or king) of your bathroom castle. Pour it in and enjoy.
