I am looking to head to Europe on a route where Air Canada is flying the A330-300. I am bigger person and find typical economy lavatories too narrow to be able to sit and do my business. Does anyone know the dimensions of the lavs on the AC A330-300? I know they say the have handicap accessible but that means nothing these days. I just need to know if there is at least one roomier lav on this plane and would love to know exact dimensions if anyone has them.

Thanks in advance.
