Huntly swimming pool is set to close next month for 12 weeks for an £300,000 upgrade.
Both swimming pool plant system will be modernised and the old spa pool, which has not worked for years, will be removed to provide more plant room space for the centre’s paddling pool.
The building’s heat recovery system is also being replaced.
Gym-goers will be able to work out in a much more temperate environment thanks to the installation of a new air conditioning system and the changing room floor will be replaced.
John Harding, from Aberdeenshire Council, said: “We are delighted these essential works are now taking place. This is a large investment of over £300,000.
“We know some people will be disappointed at the loss of the old spa pool but it was no longer repairable and its removal will allow for some other essential plant upgrades.
“We are confident these wider improvements will make the swimming pools, gym and changing environments far more comfortable for customers.”
The council said nearby swimming pools can be found in Turriff, Alford, Banff and Inverurie while Huntly’s is closed.
