The 4moms® Cleanwater™ Tub features a unique design which provides a constant flow of clean water. The clean water reservoir holds fresh water for rinsing while dirty water flows out of the side drain. The built-in color-coded digital thermometer helps you identify a comfort zone, maintaining the perfect temperature for your baby. The Cleanwater Bath Tub grows with your infant in 3 stages, making it the only tub you will ever need. Received off of registry. Once we got it home and opened the box we realized we just don’t have the space for it. Never been used, taken out of the box for maybe 5 minutes. Can only return for store credit and we don’t have the need for anything else on the website.
