The lightest floor grout will get dirty fast and also pops in an odd way with the hex tile. The more grey grout of the floor options makes better sense.

The choice you posted for the wall tile seems really off. Look carefully at tons of inspiration pics for your exact same tile and see how different grouts change the look. How close can they be spaced? Are you soing horizontal stacked?

@Kendrah thank you. The blue tile is equipe artisan in aqua also sold as Bedrosians cloe baby blue. I plan to do them stacked vertically and offset. Planning for minimal grout lines.

I'd choose Avalanche, a soft white ... seal the grout, it will stay fresh forever.

that said, I am so blown away by people who complain about dirty grout.

How dirty must one be to whine about tile grout? sorry, just had to vent.

all your selections look lovely, they'll be stunning! Happy Christmas!

That type of wall tile needs larger grout lines, or the lippages and irregular grout lines will shout really loud at you. For the floor, Cobblestone is in between Frost and Silver. Mint is discontinued, so not sure why they have that as an option. 5230, Armor, is a brand new color, and a bit lighter and bluer than Silver. But Silver is the best of the 3 shown.

Have your tile installer make a mockup with the grout, do not trust the website pictures or the samples.

Great points thanks guys :)
