I'm so glad a professional tile installer put this tile in my bathroom for me! Although the "pebbles" are manufactured on sheets, the sheets don't fit or merge together on any side to create a cohesive flow. My installer resorted to hand-placing many of the pebbles into the gaps left when applying one sheet next to another. He did a great job and the tile is very cute finished, but it took more hours and labor $ than expected. Woe betide the newbie do-it-yourselfer on this product.
