Glasgow City Council is hopeful of securing a tenant who will splash out on renting the premises in a South Side park, generating funds for the local authority.
Council bosses decided to lease the public loos in Queen's Park, on the South Side of the city, which were closed in 2005.
No asking price has been set - with the council inviting would-be renters to make an offer and give the building a new lease of life.
It is believed the site could be used for a variety of purposes, including a shop, kiosk or takeaway.
However, critics have called the rental "counter-productive", with suggest-ions the council would be better off re-opening them as public toilets.
Local councillor David Meikle, said: "This is an interesting proposal, which requires consideration. I am aware the issue of public toilet provision - the lack of - was highlighted in the Shawlands Town Centre Action Plan.
"Therefore it would seem counterproductive to get rid of toilets which could be used by the council to address this issue.
"I trust the council will consult with Shawlands' councillors, the community council, and Friends of Queens Park on this issue, to see if this is the best route to take."
The former public toilet block contains both male and female toilets.
Further details about the building are due to be released when the property goes on the market.
A Glasgow City Council spokesman, said: "We have appointed an agent to handle the facility and it will be introduced to the market in the near future.
"We welcome sub-missions and will use them to determine the future use of the site."
It is understood the money made from the property will be reinvested in the city's parks.
In 2009, a public toilet in Kelvingrove Park was transformed into a cafe.
The Queen's Rooms, which were built almost a century ago, had been lying unused for around 27 years.
However, the building was given a new lease of life when it was turned into an organic cafe called An-clachan.
