Councillors voted last month to reopen the 10 public toilets on a restricted-hours trial basis between the hours of 11am and 3pm, ensuring the facilities could be operated and cleaned safely during the continuing coronavirus crisis.
Now the opening hours are to be extended to 10.30am to 5.30pm, with each facility cleaned four times daily.
A District Council spokesperson said:
"In the main the reopening has been successful, though, sadly, our staff have at times been subjected to verbal abuse from members of the public.
“However, following the reopening of retail, bars and restaurants, we believe it makes sense to extend opening hours, though users should note that three of the four cleans will happen during opening hours."
