Marble tiles for the bathroom?

Since I was released early from work today because of the lovely first day of summer, I had some time to go back to the bathroom place. They had called us with the good message that there was a cheaper solution than the hand made slab of belgian hardstone that we wanted for the shower basin. The solution was basalt, also a natural stone. Only drawback was the order time of at least 10 weeks. So the best and nicest way forward seems just tiling the whole floor. Just need to decide on the colour now!

And for the walls we'll just stick with the good old Metro tiles. They'll make a nice contrast with the modern taps that we have in mind.
