Thank you for your compliments Sweetieferret! You can probably get this marble from any tile showroom that sells natural stone. It is beautiful stone and one of my favorites. Marble will lose it's shine over time due to soap and hard water (which we have here in Phoenix) and should be sealed regularly. I think they recommend annually, but I would check to be sure. At some point in time, you'll need to have it buffed to bring it back to life. Using a polished natural stone in a shower is a little of a sacrifice because it does require upkeep, but it's so beautiful! There are beautiful porcelain products that mimic this stone. I would look into that if you don't want upkeep. Good luck with your project!
