Smoosh scrubbers are compatible only with Smoosh bars. See, there is no standard soap shape out in the world. And soap bars don't have the necessary features for fitting in (and importantly: holding in place!) inside of a scrubber. So we had to launch a soap company alongside our innovative body scrubber. The Smoosh system was born: and it's excellent. You're going to love our soaps, and we're excited to continue to grow out our lineup of scented and non-scented options as we grow. You're feedback is important to us, so please join us in smooshing today and let us know how we can keep getting better for you.
