General Tile Discussion

Hi all, I have recently tiled a large bathroom in Empyrean Ice white marble 12x24 tile but am having great difficulty finding a grout that will work. All of the tiles have had all six sides sealed prior to install. I would like to stay with white (or another similar bright) grout, as darker colors really take away from the modern look of my home.

I have tried spectralock epoxy grout (bright white) but the grout picture framed really badly. Ardex WA did not but all of the light colors are not available due to some quality issues. Ardex DG1 (3 light colors) all picture framed really badly as well. I have tried ardex unsanded grouts (FG-C) and these did not absorb into the tile but the quality looks really poor .

I am kind of desperate as I have spent a lot of money trying different grouts with no luck. I would like to use an epoxy or another high quality grout to avoid short term issues with grout discoloration or early brake down. Experienced help is really appreciated.
