OK Baby Onda Support Bars White. The cleverly designed Onda Support bars can be used to fix the OKBaby Onda Baby Bath or Onda Evolution Baby Bath across most standard adult baths, raising the baby bath to a comfortable level for bathing. Using your baby bath directly over the adult bath removes the need to lift or carry a heavy, full tub to the bath to empty it and keeps most of the splashing where it belongs! The expanding non-slip durable support bars adjust in size (min 53cm max 75cm) and can be easily fixed directly (with the screw pack included) to the Onda Baby Bath or the Onda Evolution Baby Bath.
