The elderly gentleman had had a stroke and was continuing to use the toilet by squatting on the rim of the pan. This was very unsafe. A floor level toilet could not be installed because other members of the family use it in the normal way.
A steel framed double platform with cork surfaces was made to fit either side of the toilet pan, at the height of the rim. It has a pull-out step to aid getting on to it and the platforms do not project forward of the pan/normal seat.
The client is now able to use the toilet more safely and other members of the family are not inconvenienced.
