"Oh, our classroom doesn't have a roof any more but it's okay! We'll have cooking class outside today!"
You're exaggerating a situation you don't know the first thing about.
dr_pepper said the ceiling in one room had an issue. That could just be that the ceiling tiles are out of place, or there's a small leak. Not that the entire building has no roof.
You also have to consider the budgets that schools get, and where the money comes from. There may be grants given to them from government awards or other bodies that help them put in things like toilets.
Or, having gender-neutral toilets may give them access to other rewards for making their school more accessible, thereby giving the school more resources to use in other areas.
None of us, even dr_pepper know the full details behind how his school has chosen to currently spend money.
