An anti-gravity toilet forms part of an auction stocked with items from the Soviet space programme.
Other lots included in the sale include spacesuits, a head shield and a space glove, according to the Canadian Press.
Sean Quinn, evaluator at the Toronto-based Waddington's auction house where the sale is to take place, said that this collection of 40 items offered buyers a unique opportunity compared to other space-related events.
He told the news provider: "This is a pretty significant collection in that we have so many actual pieces of space ships.
"A lot of space auctions tend to have a lot of autographs and stamps and that sort of thing but we have a lot of actual artefacts from the Soyuz spaceships and many of those have actually flown, which is important too."
A spacesuit worn by cosmonaut Anatoli Pavlovich Artsebarsky is expected to sell for between $25,000 and $35,000. He clocked 33 spacewalking hours in the suit in 1991.
