The award-winning Toilevator is the leading toilet riser that adds 3.5 inches in height to your existing toilet. Suitable for people with mobility issues such as arthritis or those who use a wheelchair, the Toilevator helps users maintain independence. The Toilevator is easy to install and stays secure in the proper fixtures. There is no special cleaning or maintenance required for the device, and it fits standard round or elongated toilet bases. The Toilevator is often preferred over supports attached to the toilet seat because it is more discreet and never needs to be removed.
