What is the best material to use for a tile shower?

Question:I am completely re-doing one of the bathrooms in my home and I would like to put in a stand alone tile shower. Can someone tell me what the best material to use for it would be? Ceramic, porcelin, slate, travertine, marble?? Are any better for walls/floors/wet areas than others?

Answers:
The tile isn't as important as what the tiles are mounted to. Make sure you use material specific for wet areas. as for which one to use, it would depend on which one you like, and can afford. I like the looks of bigger tiles, but would much rather install smaller tiles. Bigger tiles can be a pain when it comes to making difficult cuts.
