The pools at Guernsey's Beau Sejour will be closed during part of the summer holidays for a refit and deep clean, ahead of next year's Island Games.
A new surface will be laid around the outside of the pool, and some cracked windows replaced.
The pools will close from Monday 18 July to Monday 15 August.
Bosses say the maintenance is timed to coincide with the pools' quietest period.
"Unfortunately, due to ongoing operational staffing challenges this summer, we are unable to provide an alternative indoor swimming facility on this occasion.
However, customers can be reassured we have scheduled this closure during the summer months when historically footfall to our pools is at its lowest.
As a result, we hope this closure will impact as few customers as possible. Instead, we encourage customers if they are able to, to perhaps enjoy a sea swim at the many beautiful beaches that Guernsey has to offer." - Sam Herridge, Head of Recreation Services.
