Rental Bathroom Renovation

Ok, I wish this were actually about bathroom renovation. But, as I live in a rental, it's only about trying to make my truly heinous, beige bathroom slightly less so.

As I just mentioned, my bathroom is beige. Builder's beige. The floor and half the walls are tiled with builders beige and the upper half of the walls are painted to match. The only variety in the room comes from the white elements, i.e.- the ceiling, toilet, sink and bathtub. How sad is it when you think of your white toilet as adding interest?
