Although ADA does not specify the dimension, several states, including California, Texas and Illinois, require a urinal lip to extend a minimum of 14" from the finished wall. Flush controls must be mounted no more than 44" above the finished floor and comply with ADAAG specifications. A minimum clear floor space 30" wide by 48" deep must be provided to allow forward approach to the urinal.
