The toilet was among Beatles memorabilia sold at auction as part of the Beatle week festival in Liverpool, the group's native city in northwest England. The pre-auction estimate was 750 to 1,000 pounds.
Anne-Marie Trace, who works at the Beatles Shop in Liverpool which organized the sale, said the high price paid had taken the organizers by surprise.
"I think it's the most unusual item we've ever had in our auction," she told Reuters.
The buyer was not identified but Trace said it was likely it was "going overseas."
