Eastleigh Borough Council (EBC) will carry out a £45,000 feasibility study into options for future improvements to the Hampshire town's Fleming Park Leisure Centre.
In a recent meeting, members of the council's cabinet acknowledged the role of the complex in promoting active lifestyles and approved - in principle - investment in its facilities.
A report put forward options for improvements including a refurbishment of the existing site at a cost of between £7m and £12m, as well as a complete rebuild costing up to £22m.
The feasibility study will explore the "true building costs" of each option based on outline designs, as well as an initial business plan highlighting potential for increased revenue.
The cabinet report said: "There is clearly a need to take some action and on the face of it there would appear to be a financial case for developing a new leisure facility.
"This would support the very strong argument for remodelling leisure provision in a way that meets the needs of the 21st century and addressing some of the key issues around healthy living as articulated in the corporate plan."
