I laid the shower floor tile on Saturday. The tile is the same marble that is used on the bathroom floor. The bathroom floor tile is 12 in x 12 in tile with a brushed finished. The tile in the shower are smaller pieces that have been tumbled into odd shapes and placed on a mesh to give a cobblestone appearance. I really like using this type of tile for a shower floor because it is naturally slip-proof and feels really good on the feet. The only problem with using this type of tile though is fitting the different pieces together. They don’t line up the way regular shaped tile does. I removed pieces from the mesh of unused tile to fill in any gaps where the tiles met or where a tile met the edge of the shower. It is a bit of extra work, but I really like the appearance and think it is worth it.
