Baker continued: "Talking to the Penrice students, I have decided to remove the outer doors of the boys’ toilets for a trial period.
"This decision was taken due to small amounts of vandalism, but more importantly that younger students identified the toilets as an area of the school where sometimes they felt uneasy about entering.
"So far the response from the children and the feedback from individuals has been overwhelmingly supportive of this decision."
Baker said all "safeguarding aspects" of the decision has been reviewed to "ensure that privacy is not compromised for any student or member of staff".
He finished by saying he will decide whether the trial period worked at the end of the school term.
Stressed parents commented on the Facebook status to express their concerns.
"There are a lot of female students who are feeling extremely uneasy about the situation," one mother with a child at the school wrote.
"They are saying they can see the boys using the urinals when they are walking past."
Another mum wrote: "There is no way in the world this is an acceptable solution, this is the most disgusting thing I have ever heard.
"Build some more toilets for goodness sake or let the children use the staff facilities and see how quickly this abhorrent situation is resolved."
Others claimed they had not been contacted about this decision and only found out via Facebook.
"Could I ask why the parents were not consulted please?" asked one mother.
Another wrote: "How many students do you actually talk to? I have two children in different years and neither of them are supportive of this decision."
The Huffington Post UK has contacted the school for further comment.
