Tiling for Kitchen and Bathroom

I have been looking at a lot of different kitchen and bathrooms online trying to work out what looks good and I have decided to go white tiles in both the kitchen for the splashback and the same in the bathroom on the walls. For the bathroom floor I am going a slight tan type colour. Hard to explain, but it looks good.

In the builders selection you don't get an allowance for any feature tiles, but I decided I would like something. I think I am going to get a vertical strip in the shower using pebbles 3 wide that look like these:

I have been quoted about $105 for the tiles and then I need to allow for labour as well. I will ask for the labour quote and then decide.
