West Yorkshire's Wakefield Council is planning to build a new £14.8m swimming and leisure complex in Pontefract.
Plans for the complex, unveiled this week, include a 10-lane swimming pool, studio pool, gym and exercise suites, a sports hall and a climbing zone.
The proposals for the centre also include a cafe and soft play area, community space and exercise referral rooms as well as outdoor tennis courts and five-a-side 3G pitches.
The centre would replace existing leisure facilities in Castleford, Knottingley and Pontefract, which would close under the proposals.
Castleford Pool, built in 1983 and Knottingley Sports Centre, built in 1969, would shut in January. But Pontefract Pool, dating back to 1985, would remain open until the new centre was built.
