This is a Rolling Shower Base designed to be use with the Anchor Pediatric Bath Chairs. The base, which attaches easily and securely to the bath chair, allows the bath chair to be conveniently rolled into shower areas. With the base attached, it's a snap to position and reposition the chair as needed. 4 casters and a sturdy base help to make sure the chair doesn't tip or lean over. Height adjustable, ensuring the proper positioning of the child to get clean. A child should never be left unattended while the bath chair is in use. The Rolling Shower Base comes in one size but fits both sizes of Anchor Pediatric Bath Chairs. Using the base does not interfere with any of the adjustability of the Bath Chair. The high-quality casters ensure that the base can be used safely in wet, slippery environments. Easy to clean needing just warm water and soap.
