Plans for the development, on School Drive, will see the installation of a climbing wall, a 100-station fitness suite and a 25-station group cycling studio across a two-storey building.
The larger swimming pool will measure 25 x 12.5 metres and alongside it will be a learner pool measuring 15 x 10 metres which will feature an adjustable floor.
Work is scheduled to begin this year and the new centre is expected to be open by the end of 2017.
Morgan Sindall area director, Richard Fielding, said: “We’re pleased to be involved in this project and confident that the finished facility will be well received by the local community.
“Once complete it will provide the people of Bromsgrove with a modern environment in which to exercise and prove an enduring addition to the leisure offering in the area.”
The centre will be self-funding, unlike the current Dolphin Centre which runs at a heavy annual loss, and the process of selecting a day-to-day operator to run it will shortly take place.
The leisure centre is the latest redevelopment in Bromsgrove under a strategic Town Centre regeneration partnership of public bodies that was formed in 2010 to redevelop areas of the town, making major efficiency savings across the public purse.
This has led to the total revamp of the high street, major retail developments coming forward across the town and a near-total overhaul of public buildings.
