Because parents don’t want baby soup! Normal baby bathtubs hold very little water, and once it gets dirty, you’re done. The Cleanwater Baby Bathtub drains the dirty water out of the tub so your baby isn’t sitting in it. Fresh water is held in the reservoir for rinsing. Cleaner water. Cleaner baby! The color-coded digital thermometer makes it easy to set the perfect temperature for baby’s sensitive skin. It even includes a bath sponge for added support for newborns.
