Greg Kohfeldt, owner of Kohfeldt's Auto Repair in Florence, said the toilet was installed by the previous owner of the shop in the 1950s and came from the German dictator's favorite yacht, the Aviso Grille, The Times, Trenton, N.J., reported Monday.
The yacht was commissioned in December 1934 and was taken by the British following World War II. The vessel was stripped down for scrap in the early 1950s and the toilet and sink ended up at the auto repair shop, which Kohfeldt purchased 19 years ago, the report said.
Kohfeldt said the toilet and sink would draw one or two visitors each month and the number jumps to six to 12 people a month whenever the items appear on TV or in print media.
The owner said he is planning to remodel his bathroom and put the Hitler toilet up for display.
"If someone actually had an interest in what is left of the sink and the toilet I would probably sell it," he said. "But they'd have to have an interest ... if someone is just going to offer me $100, it'll sit here forever."
