I purchased this tile for a shower floor that I'm installing for a client. They found the tile originally at a design center of a large tile supplier. Wayfair had a better price and delivered very quickly. 

Pros: These stones provide a great floor in a shower because of the cut and tumbled surface. 
Cons: some of the stones fall off the mesh while handling them. Shouldn't be a major issue installing them on a shower floor but would be a pain trying to put them on a vertical surface.
