According the the council, works are taking longer than first expected and, in the best interest of public safety, the centre will remain closed until works are completed.
The fitness centre is open and operating on winter hours.
Winter hours at the fitness centre are Monday to Friday: 6am-7pm; Saturday 9am-4pm; Sunday 10am-4pm
The council stated it apologised for any inconvenience.
