I dont know who made it - but it's called "Penny Tile" due to the size and shape...
...but it makes for a lovely shower, doesn't it?

Thanks so much.

This look can also be created using Merola Tile's Penny Round Light Blue. It can be found online with the Home Depot. http://www.homedepot.com/p/Penny-Round-12-1-4-in-x-12-in-Light-Blue-Porcelain-Mesh-Mounted-Mosaic-Tile-FKOMPR42/100572934#.UbCslkCcfFM

Hi Natalia, I know these comments were a while back, but I wanted to check on this type of tile again. I'm doing blue penny tile in my bathroom, and I have a sample of the Cepac blue mine looks like it has a slightly dark edge, slightly weathered look. Your tile in this photo doesn't look that way. Do you remember whether your tile was like that and the grout covers that up? I really like this slightly aqua color, and wondering whether it's a different one than the sample I have.

It is actually Cepac Tile's Classic Round Collection color CR-2 Aqua. :-)
