Parents at Morriston Comprehensive School in Swansea are advising their children not to use the toilets after they were changed to unisex.
The toilets have separate cubicles for boys and girls and the doors reach from floor to ceiling.
The only shared area are the wash basins.
Both the school and Swansea Council say that the new toilets have reduced incidents of bullying and loitering.
