A former public toilet block in Bath, close to the city's cricket ground, is to be auctioned with a starting price of £20,000.
Network Rail wants to sell the public convenience and 0.023 acres of surrounding land.
The unusual property is described as a "stone-built single storey former public convenience arranged beneath a pitched tiled roof".
The auctioneers say the site "may afford potential for redevelopment".
They also point out the lavatories are built on a site that is "irregular shaped with frontage on to North Parade Road and Pulteney Road".
The toilets go on sale on Thursday, 16 December in London.
