Can this room be as gorgeous with tiles?

I totally love the relax vibes of this room, the light, the space and the white metal lockers. I've seen a couple in the brocante nearby and I may check them out again to see if they would work inthe kids bedroom but I can't help wondering if this room would look as fabulous and relax with tiles or carpets for instance.

I'm asking this because I see a lot of gorgeous, inspiring rooms but they all have wooden floors and frankly even if your floorboards are old and distressed, with wooden floors, your decoration job is half done.
So I'm really interested in finding out what you've managed to achieve with your house when the Decoration Fairy God mothers were not on your side.
How creative were you to overcome something that you felt was a major eye-sore without breaking the bank?
