Both Gloucester Green and Market Street are now benefiting from full time attendants at their public conveniences.
The trial will see full-time attendants present at the facilities between 10am and 6pm. The move is aimed at cutting down on the anti-social behaviour that has marred these conveniences in the recent past.
These two sites were chosen for the trial as they are the most heavily used and most prone to suffer from misuse. Additionally they have the highest profile with visitors to the city.
The attendants will focus on maintaining the cleanliness of the sites and availability of facilities. After the trial ends the Council will decide whether to fund a continuing presence at Gloucester Green and Market Street.
Cllr Nigel Chapman, Cabinet Member for Safer Communities and Customer Focused Services said: "These two city centre conveniences have suffered more than others when it comes to unwelcome anti-social behaviour. We have, for example, seen a large number of discarded needles left in them - this is unacceptable for city centre facilities that are used by residents and tourists alike. So, we were keen to have a full-time presence to make sure that when visitors use these conveniences, they will find them in the best possible condition.
"Maintaining clean and welcoming public conveniences is a benefit for all visitors to our city, wherever they come from and improves their experience and impression of Oxford."
