Baywave TECT Aquatic and Leisure Centre will reopen to the public tomorrow after it shut down due to safety concerns.
The pool complex is expected to open at 2pm, eight days after it was shut for urgent seismic upgrades following a preliminary draft of a BECA report assessing the centre as being a Grade D seismic-prone building.
Bay Venues chief executive Gary Dawson said "great progress" has been made on remedial works.
The construction team completed the works over the weekend - ahead of the initial nine-day turnaround which would have had the facility reopening on Friday.
Strengthening included infilling a window so that it became a solid wall and adding bracing to the steel girders that run along the spine of the building. Installing six plates takes the centre from a Grade D to a Grade C seismic risk.
