Organisers of one play area bought £65,000 of play equipment for juniors and toddlers including a bank with funnel and tube slide, pod swing and adventure trail kit.
Existing gear had aged or been vandalised, said Bath & North East Somerset Council, which funded the work at Claverton Road Play Area.
The local authority has awarded over £250,000 to 52 play areas since it launched its funding scheme six years ago.
Alexandra Park in Bath recently received £20,000 for improvements, and the investment was in addition to the council running the Government Play Pathfinder Scheme.
Councillor Charles Gerrish said, "Bath & North East Somerset Council has listened to children and parents to deliver schemes the community can be proud."
