- GO AHEAD, GET NAKED. Boon's updated NAKED baby bathtub is better than ever. The one-piece design now includes a built-in bump on one side, creating a supportive recline that's perfect for newborn baths. Growing babies and toddlers have plenty of room to play in the suds while sitting up on the other, wider side of NAKED. When bath time is done, the updated legs feature easy-click buttons that make them simple to fold down.
