Press Packer Sara got in touch with Newsround to tell us how bad her school toilets are.
So we want to know what the loos are like at your school.
Are they shiny and new, with lots of light and clean and fresh every day?
Or are they really old and in a room that's really small and smelly?
E-mail and let us know now!

"My school toilets really stink! They're so old the same ones were there when my Dad went to school! There's loads of toilet paper on the ground and most of them are blocked!"
Czara, 11, Republic of Ireland
"My school toilets aren't great. The locks are difficult to operate sometimes and they don't put toilet paper in the cubicles so you have to get it before you go in! There are some days that you have to go without, because there is no paper. I try to avoid them as much as possible."
Heather, 13, Carrick Fergus, Northern Ireland
"They're ok, but no one ever flushes the chain and some doors don't lock."
Megan, 8, Salford
"My school toilets are fine, they always have toilet paper and refill the soap holders. The only down side its that one of the locks are broken."
Cara, 11, Worthing
"Our toilets are filthy and most kids need to learn how to aim!"
Arif, 12, Essex
"My school toilets are just a hole in the ground in the playground with doors, and although they flush the water is turned off in winter as the pipes freeze!! I never use them and wait until i get back home."
Millie, 10, France
"In my old school the toilets were horrible and there were all soggy tissues stuck to the ceiling. They would sometimes fall down on you. How disgusting!"
Houda, 12, London
"Our toilets smell so bad, though we have Japanese style ones that we don't have to sit down on. But pee is all over the floor, we have slippers to change into to go into the bath room that are supposed to be blue and pink but the back is covered in black gunk, and the windows are so small we barely get any air. Since we brush our teeth right after lunch, the sink smells like saliva, so gross!"
Emily, 13, Japan
"My toilets are great because they are in my home - as I am home-educated!"
Emma, 9, Harrow
"Our school toilets have even had rats and there's no soap!!"
Rachael, 12, Chesterfield
"I go to a school in Penderyn. We've got a brand new school. The toilets are fine. But the toilets in our old school were DREADFUL. Used loo roll everywhere, writing on the back of the doors, broken locks. You wouldn't want to go there! All you would see is a great big vat of yellow water!"
Alex, 10, Merthyr Tydfil
"Our school is getting knocked down, so we're in Porto cabins. The toilets look OK at a glance because they're new. There are 4 toilets, and boys AND girls can use them. So every time there is always pee around the seats from the boys, and the girls find it a nightmare."
Emma, 11, Hereford
"Our school toilets are disgusting! There's nothing good about them. The girls have about 10 toilets but we can only use 2 of them as all the locks are broken. The sinks are minging so nobody really uses them. There's never any soap or toilet roll and half the taps don't work."
Rebecca, 13, Derby
"Our school toilets are new and shiny and we are gonna keep them that way!"
Emily, 8, Barnstaple
"The school council has been doing loads of fundraising events to improve them, fortunately! They aren't too bad, though."
Ellie, 11, Mirfield
"Kids in my school put paper towels down the toilet and block them! The toilets are too low down - and so are the doors!"
Callum, 8, Evesham
"My school in America has okay toilets. They are usually quite clean, but once my friends and I found a snake in one of them!"
Luna, 10, America
"Our school has just spent LOADS on new school toilets and they are sooooo cool. If your school doesn't have much money, raise money by having cake stalls or jumbles sales."
Lottie, 11, London
"The school ones are OK, it's the toilets in the changing room that are horrible! The loo seats are always broken or wobbly and there must be a problem with the sewers coz they always reek which makes the whole changing room smell! It's horrible, especially as we have PE before lunch!"
Becca, 13, Milton Keynes
"The girls toilets in my school are really nice but there's one problem, they have rude graffiti everywhere!"
Ceri-Anne, 12, Bridgend
"Our toilets are foul. No one ever flushes them, the mirrors are gone and the graffiti on the back of the door really is gross."
James, 13, London
"Our school is fifty years old and about to be knocked down. They say there is no point in smartening them up, but they need it! We have no locks and even no soap. The toilets are awful, and one is only 30 cm high!"
Lloyd, 12, Norwich
"My school's toilets are only nice for the Year 10 and Year 11s. Unfortunately, the ones for my year are the worst - broken locks, smelly and the soap dispensers don't work!"
Lola, 12, London
"My school toilets STINK! They are really horrible! They are never flushed and always blocked . The boys toilets are even worse!"

Naomi, 11, France
"My toilets at school are disgusting! I wonder how the teachers would feel if they used them?"

Megan, 10, Harrogate

Lily, 11, Nottinghamshire
"Our toilets at my school are generally very good, but at one of my previous schools, it was horrible. The doors were so small that you could see over them - UGH!!"
Melissa, 12, Cumbria
"My toilets are those horrible metal ones that always really stink and have too wide pans. I wish we could get new ones!"
Bethan, 12, Stockport
"The majority of school toilets smell - it's a well know fact of life! It's because no-one can be bothered to treat them how they would treat their own toilet and the school doesn't put enough money in to making it look good!"
Nicola, 13, Bristol
"They are in an appalling state. The caretakers should do more to make the toilets hygienic."

Claire, 10, Scotland
"Our toilets really stink. When you go into the toilets, they really make you want to be sick."

Shannon, 12, Bradley Stoke

Rabia, 13, Dubai
