Lavotorium 

A very elligant bathroom with a skylight and toilet paper is dispensed by a guy named Geeves.

I felt the need to take a Lavotorium break during our training.

lavitorium

A fancy, clean, or “executive” bathroom, usually a public one.

Person 1: “I have to use the lavatory.”
Person 2: “Don’t use that one, use the lavitorium on the second floor. It’s really fancy and decorative and has those automatic sinks and paper towel dispensers.”
