whatever you do, DON'T buy ivory! ivory bar soap leaves the thickest soap scum on my tub i've ever seen. pure my big, white behind! our daughter uses softsoap body wash, and her tub still looks as new and clean as it did the day we installed it, while DH and i use ivory bar soap and no matter how hard, how often, or what we scrub it with, the soap scum will NOT go away. i hate it, it looks terrible and i'm ashamed for anyone to see it. oh, and our tub and DD's were installed the same day, same brand and style, just a different color (beige for hers, off-white for ours). i've always used ivory, and have very sensitive skin, so i'm not sure switching soaps is an option.
