Hi Martin1674,
It has been a number of year since we did this job. But there are a number of suppliers in my area that we commonly use. I would suggest checking with one of them: Bedrosians, Tile Shop, Bullnose Tile or Dal-Tile. They are all in San Jose, CA.
I actually just got word from one of the guys suggesting you check out Walker Zanger at Tile Fantastic.
Best of luck!
