Looking to duplicate this look in my shower, love how this turned out, very beautiful, spa like and beachey. So, I would like to find out the mfg. and color of the pebble tile on the shower floor, and also the color of the grout you used. I'm finding out grout color really makes a big difference on the end result. Light, medium, and dark grout look very different even with the same pebble tile. Also, any tips on type of grout or any additives necessary would be appreciated.
