Coral Daydream Series - tile selection

Help! I'm finding it really difficult to settle on what kind of tile I want in my house.
I had originally thought the 300x600 through the main area and 300x300 in the wet area and bathroom wall tile. I was unsure of the way it looked transitioning from bathroom to hall. Now I'm thinking just get the same tile throughout the entire house but I'm also not sure that the 300x600 is going to look good running the same way as the rest of the house. So then I thought maybe 600x600 throughout the entire. The tile that I like is a earthy brown porcelain tile and know I can get in any of the mentioned sizes. Not sure of what colour wall tile to put with it either.
Sorry about the long post, just hoping for some direction. Pictures of your daydream bathrooms would be much appreciated for inspo!! Thanks.
