Essential maintenance works mean the swimming pool at Morriston Leisure Centre is being closed until early in the New Year.
The works to repair pillars supporting the pool area began last month and are expected to last for a further six weeks.
The pool is scheduled to re-open on Monday January 3 with a full resumption of normal services on Monday January 10.
Dave Osborne, Swansea Council’s Leisure Operations Manager, said: “We’re temporarily closing the pool to carry out essential maintenance to the pool area.
“We apologise for any inconvenience this may cause our customers but I’d like to remind them that our other Active Swansea pools will be open.”
