michigammemom Cynthia is correct, the river rock tile is available as a listello border and in meshed panels for larger applications such as the shower floor pictured. Due to the natural contour of the pebbles, the grouted surface will have a slightly bumpy texture.
Charmean Neithart Interiors, LLC. The pebble product I have sourced comes in a 12" sq. sheet. If installing this product the grout joints have to be perfectly even so that a "grid pattern" doesn't surface. This is best achieved with the thinnest grout joint possible. Hope that helps.

Ann I have the pebble-tile-grid in two bathrooms .... and it is fantastic. If you use the shiny sealer, the rocks look wet all the time ... and improves the 'look' . They feel great on your feet.
