Looking for males for a photoshoot

Hi everyone!
We're a student group working on a short film project and we're looking for a location for a 1-day shoot in late Feb - a toilet with a mirror and urinals, ideally with school-like decoration or just a toilet in a sports centre. We're very limited in budget and only hire for 1 day or less, so it would be nice to limit the budget to 100 pounds for the location. It could be a suburb.
If anyone has any recommendations on finding such a location in London, could you please contact me?
Thank you guys so much for your help! Looking for recommendations in London, United Kingdom
