Cowdenbeath Leisure Centre will close for more than a year for a major refurbishment.
Plans include moving the library and upgrading all of the facilities, including the gym, sauna, steam room, changing areas and the pitch.
Work starts on April 15 and the centre won't reopen until next autumn.
Fife Sports and Leisure Trust bosses say the work will take about 14 months to complete.
Emma Walker, CEO at Fife Sports and Leisure Trust, said: "Cowdenbeath Leisure Centre is a vital part of the community, promoting physical activity, sports, and leisure. This ambitious endeavour promises an array of benefits for both customers and the broader community."
Scott Urquhart, head of operations at Fife Sports and Leisure Trust, said: "We have carefully planned the relocation of activities to ensure our customers can continue their fitness and leisure routines during the renovation.
"We are grateful for our customers' understanding and cooperation during this transition. The upcoming renovation of Cowdenbeath Leisure Centre represents a significant step towards creating a more vibrant and integrated community space."
Until the start date all classes and activities will continue as normal.
While work is ongoing there is temporary arrangements in place. Some classes won't be held while others have moved to nearby centres.
Linda Erskine, Fife Council's spokesperson for communities and leisure, welcomed the announcement which she says "will mean a much improved facility for everyone".
She added: "Providing better sporting facilities for Fifers is an important priority for the council.
"The improvements to Cowdenbeath Leisure Centre will have a transformational impact to the local neighbourhood and provide a facility which is welcoming and inclusive to all and provide integrated services of leisure and cultural spaces."
