Should the grout be the same color? Not necessarily. Will it look weird to use a darker gray on the floor and a lighter gray in the shower? Not at all. Any recommended colors for the shower and floor tiles along these lines? I've been getting stuff at Lowe's and they carry MAPEI Warm gray for the subway tile, and silver for the hex, if you lke a darker grey for the hex. Silver is actually a medium grey, but it'll appear alot darker with the white tile. Our bathroom isn't perfectly square. I think a colored grout seam that is uneven will be really obvious(that's my understanding where you would do any flubbing). Can you grout just the seam white? Can you skip grout and caulk it? Any suggestions here? Grout everything on the floor the same color. it'll actually show up more if you try doing what you suggested. It'll literally draw attention to it. What you want to dpo is make sure that you're square to the most obvious walls from the door. Especially with the hex, it won't be quite as obvious as you think, unless it's WAY out, and then nothing you can do will hide it, even using a blending color grout. One other thing-- that joint where the floor hits the walls should be caulked, but still caulk it with a caulking that matches the grout, both color AND texture. Does anyone know what the measure is for hex tile and subway? For subway, use unsanded, and for the hex, use sanded.

morton5, you could actually go in a couple of different directions with that tile. Both greys AND tans would work with it. Custom-- Antique white Bone Linen Oyster grey Delorean grey Laticrete-- Antique WHite Latte Parchment Smoke Grey Sterling Silver Mapei-- Bone Ivory Summer Tan Silver Pewter As for the "woofer", he's great-- just won't let me post!! I've been working on this one post now for about 20 minutes!! He think's it's play time!!

I think dark brown grout would make the tile colors pop.

personally I think trying to match the blue would be too matchy. (note I'm not a pro. I am a graphic designer who is extremely color sensitive, but I'm not an interior designer, so take that for what it is.) So, my vote is #9. It's a grey that compliments both the blue and white tile. And it's not too dark or light, so you can get that reduced contrast look you're thinking of. However, did you get that sample color off the web? It's far better to go see it IRL. Take home some samples and view them in the room where they're going, next to your tiles. See if the vendor will actually grout some sample tile for you if possible.
