Smaller apartment - smaller bathroom

[SunnyArms]

I've been fishing for tips on how to make my small bathroom look bigger. I found one of Caesarstone's blogs that talked about how to design a small bathroom. It said: sliding doors, wall-mounted vanity and toilet, and big tiles (or at least the correct size ones). It's my first time having an apartment on my own so I'm kind of clueless about what to do here. What else can I do that won't really let me violate any contract clauses? TIA.
