The images show how the charity will restore the heritage site, bringing the historic Grade II building back into use by creating a unique health and well-being destination for the people of Newcastle.
Plans for the site include a new health and fitness facility, improved access for disabled people and a new cafe.
Peter Kay, chief executive of Fusion Lifestyle, said: “We’re pleased with the plans for the development and these new CGIs show how we’ve worked with the structure of this iconic building to create something the public will be proud of.
“Interest in the site and public support for our involvement has been wonderful and we look forward to hearing feedback from the public on our exciting plans.”
The visuals are part of a new public exhibition in the customer service area of Newcastle Civic Centre, which will run from the afternoon of 9th May until 17th June 2016.
Leader of Newcastle City Council, Cllr Nick Forbes said: “When Newcastle City Council first faced up to austerity we said we would have to look again at how we provide culture and leisure services. The result was a question mark over the future of the City Hall and Turkish Baths.
“But we made a promise to the people of Newcastle then that we would not give up on these services, that closure did not spell the end and that our commitment to the city had not diminished.
“Today is that promise made reality as we welcome the start of a new era for of Newcastle’s City Pool and Turkish Baths. “
The facility is expected to reopen to the public in spring 2018.
