Island Stone Waveline Glass tile......gorgeous. Looked at the mini waveline for a bathroom. Here is a link that might be useful: Island Stone Waveline Glass Tile

Raffi Glass also has a version of the "bubbles". I used their water-jet glass arabesque and I'm very happy with the tile. Raffi, the designer/owner was a pleasure to work with. Just checked their website and it seems to be a bit glitchy at the moment and I couldn't get the tile photos to load. http://www.raffiglass.com/

If you instead select the simulated porcelain marble from Floor & Decor you won't have to seal the marble worry about etching pay the additional cost to have marble tile instead of porcelain tile installed purchase 20% overage so your tile setter can throw out all the tiles that are completely off color and will run the job. You can have this tile set with a 1/16" joint and no one but you will know that it's not the real thing.

Are you sure they are not just floor slickers? They are applied directly over tile. https://quadrostyle.com/collections/floor-stickers
