The public toilets next to the Tourist Information Centre reopened this week – after being closed since before Christmas.
The toilets in Cornfield Road were closed before Christmas 2014 for essential repairs to the external fabric of the building, but were reopened for the busy festive shopping period.
A council spokesperson said the improvements were necessary before any internal works could be undertaken.
The internal refurbishment programme started in January and the work was completed in March.
The toilets opened again on Thursday morning.
The refurbishment involved the complete stripping out of all the facilities and replacing everything in the female, male and disabled toilets.
Local building contractors and suppliers were used extensively and the new toilet cleaning contract started on April 1.
The contract includes an attendant at the toilets throughout the summer period.
The spokesperson said the cost of the internal refurbishment was £52k.
He said, “The toilets in Cornfield Road have opened in time to accommodate the increase in visitors to the town during Easter.
“Similarly, the public toilets in Hampden Park have also opened on Thursday following extensive improvements.
Residents were upset at the long shut down and said it was disappointing that very often it appeared that nobody was working on the site and refurbishment of similar sized toilets took just three weeks to complete. The nearest toilets were those in the Arndale.
