It's not a specific brand of tile per se and many distributors and manufacturers make virtually the same tile. It is a faux limestone which is available in 4 or 5 similar but unique colour ways. Since I am in Canada and this is an International site I feel if ou just take this photo to your local tile supplier they will be able to show you a variety of suitable options. Good luck with your project.

Actually this was a faux marble travertine but limestone is very similar.

Thank you, its one of the best bathroom's i have seen, my wife loved it and wants it for our cottage :) She likes your work.
