Inspiration for my bathroom

We have one of these standard bathrooms: white, tiny and no window. For me a bathroom should be cozy which is very difficult if you have one like ours. My dream would be a room like this with large windows and grey/brownish colors:

But I can't change the color and the size of the tiles. I might need to work with more white and silver to make it look bigger...

And to increase coziness, I've ordered a bathroom light similar to this one with fewer light spots :

I hope to get it this week and to show you some before and after pictures soon..
