You are asking about the grout (the space between the tile), right? If so, it looks white. There is no way to know the brand of grout by having only the picture. Where is the picture sourced? Sometimes details are listed.

It's a great pic btw!

My inspiration photo was similar - dark floors with light tile on the walls. I went with a charcoal grout on the floor. But white grout was used on the wall/shower tile.

The pic above has super white tile on the walls, so my guess is the grout is white. I tried antique white grout and a soft white grout in my bathroom - but my tile called for true white grout. Going by that, I assume the grout pictured above is truly white grout. I highly doubt they would use white grout on the walls, and a different shade of white or gray on the floor. It all looks the same.

The shower floor grout looks dark though.

Who knows!

Thanks, mrsshayne. I'm planning to use laticrete's silver shadow grout for the white subway tile tub surround, and was wondering if to continue that color into the black tile. I thought someone might have some experience with black tile and would know if it is likely a true white or a light grey or... I saw people identify a grout color in another thread so I was hoping to do the same. :) Oh and they identified the color, but didn't mention the company so it took me a minute to find. That's why I thought I'd ask that odd question! And the source (Dwell magazine) details the tile, but not the grout.

A light silver grout on a black floor like that one will probably look white in photos because of the contrast.

Agree. Avoid true whites. Especially on a floor. Too stark. Silver-ish, grey-ish, a close but non-white will soften and enhance the overall look.

Thanks so much, MongoCT and enduring. That is the kind of insight I was hoping to hear. Seeing the contrast between the two grout colors on the black tile is extremely helpful. Enduring, I'm wondering if you experimented with any of the other grey grouts (dusty grey, smoke grey, etc.) on the black slate? How did you settle on mixing silver shadow and platinum?

thanks. When you see the different greys in person you can see a lot of under colors that you may not like. In my 2nd bathroom with warmer features, the silver shadow and platinum would not work. You need to sample the colors. They have plastic sample sticks that are very good color renditions. But to be sure, make sample boards before the final determination. The silver shadow has a bit of a lavender under color. It worked great in my pale bluish gray bathroom (white walls and black floor tiles). In my 2nd bathroom the tiles looked terrible with the silver shadow and platinum. 2nd bathroom had warmer colors and needed the warmer grays that laticrete offers. Both bathrooms have a near perfect grout selection. I used the epoxy grout, not the cementis grout in the Laticrete brand. Very happy with Laticrete products.

Excellent, thank you. I appreciate hearing that the sample sticks are pretty accurate. I will definitely make a test board.

Try Mapei Pewter or Silver. One of the two will be the color in the hex tile, or the equivalent from another company.

This is a black slate sample board with Mapei colors. From top to bottom: Pewter, Silver, Oyster Gray.

We used the warmer Pewter in this bathroom, which works well with the crema marfil marble and Edgecomb Gray walls.

In the next bathroom with the same floor but carrara marble we'll probably go with the silver grout.

So glad we did the sample board because Oyster Gray was my first choice based on the little sample sticks but it ended up much too brown/yellow IRL.

I would strongly advise anyone again using white grout on the floor. It will eventually look dirty. That would drive me crazy. A gray would look nice.

Thank you, Bill, for letting me know about Mapei pewter and silver! I have read that some people have had issues with Mapei's color saturation being inconsistent across a wall. Is there anything I need to watch out for? I plan to hire a professional, but would like to be as informed as possible. Any insights you might have would be greatly appreciated

Juddgirl2: Your post is so helpful! I have ordered sample sticks from Laticrete, but I don't see that option with Mapei. Did you have to buy packs of each grout color to create the sample board? Or do they have samples available somewhere?

I did buy small bags of each color and just used a small amount for the sample board. They were about $10 or so each but we ended up using one of them and it was worth the extra expense for the other two. I also might use the Silver for our next bathroom project since it will work better with the carrara marble in that room.

Without the sample board, I would have probably chosen the Oyster Gray based on the little sticks but I would not have been at all happy with that color.

It may have been mentioned above already, but you can not save grout. It has a very limited shelf life. Even if it looks normal it may set up very poorly, needing removal.

That's great perspective, juddgirl2. I will do the same. I'm excited! I take it you didn't have any of the color saturation issues I've read about with Mapei?

I've never had a problem with uneven color from Mapei, especially their latest evolution of grout, the Ultracolor.

I should clarify, that I was referring to the shelf life of cement type grout

Excellent! Thank you, Bill and enduring!

Fierceandmagical: I'm curious what you ended up going with. As it happens, that's one of my main inspiration photos for my bathroom remodel. I've got the black cement hex tile down (from cle—amazing stuff) and am doing subway tile on the walls. Unlike the photo, I want darker grout in the subway tile for that classic look, and am trying to find a grout color that will have that effect while also allowing the black floor tiles to pop a bit.

damsden1: I'm actually not scheduled to do the work until October! But I'm planning to go with Laticrete Smoke Grey as it looks good in the particular lighting I have. I tried to track down Mapei samples as people suggested, but the Lowe's stores in this area are always out of all the grey shades. Perhaps I will purchase bags of their grout and do a test board in the next few weeks.

fierceandmagical: Thanks for this. I'm confined to Mapei down here in New Orleans, and decided on the Pearl Gray for the white walls after seeing it in a friend's home. I'm going to test some lighter shades (Silver, namely) on the black tiles where they extend into a closet in case the darker gray doesn't bring out the contrast I'm looking for. Don't know if you've picked tiles yet, but the black cement from cle are truly phenomenal. Happy to attach some photos...

Damsden-- If you're looking for a stark contrast, that'll do it for you. Pearl Gray is more on the darkish side of the grays, and with white tile, it'll almost appear as charcoal. You might do better with the silver or pewter. It'll still give you a pretty heavy contrast, but not NEARLY as much as the pearl gray would. One thing you want to think about-- I'm not sure what size tile you're going to use, but if it's something like a subway tile, or anything smaller than a 12x12, the grout joints might take over the surface (it'll be all you see) with this kind of contrast. With white tile, if you want something that will give you a mild contrast without being all you see, look at Warm Gray.

This is warm gray with a white hex tile

Thanks for the input. Here's the effect I'm looking to achieve with the tile—I've included a kitchen shot as well, since my kitchen is very similar to the one pictured, with 6x6 up the walls and stainless steel counters. Do you think the pearl gray is too much? My grout lines are very thin, for what it's worth.

Here's my kitchen in progress—ignore the hideous ceiling fan. That's with no grout, but it's essentially the look I want. There'll be three open shelves on the non-window wall, and a hood above the stove, to break up the massive wall of tile.

Id say if you want the look of this picture you posted then the darkish grout will be too dark, as Bill says. I'm referring to your progress picture just above my post.

damsden1: Those cle tiles look sumptuous. I'm just using the black hexagon tile you can find at Wayfair. They're still quite nice.

Bill V.: Thank you for sharing your wisdom! I can't believe how many hours I have sweated over the grout color so it's great to hear your insights.

I would bet a paycheck on the grout in that pic being warm gray or an equivalent from another company-- Laticrete's Silver Shadow, Custom's Platinum, etc.. One way or another a very light gray. This is the effect I was talking about-- just enough of a contrast to show the grout joints, but not enough where the grout takes over the look of the area.

In your sample pic, BELOW the sink is what Silver grout would look like. A little more of a stark contrast.

fierceandmagical, Bill V: so in the end I went with my gut and did the Pearl Gray. It's still drying, and lightening, but it turned out to be exactly what I was looking for. Attaching a few photos in different light, but you can see it contrasts nicely with the black tile without being too stark. Thought it may help with your remodel. Thanks everyone for all the help...

Wow, what a beauty!!!

And that paneled door to the bathroom is wonderful.

Stunning work in both rooms!

Thanks! The door is from the 1830s—had to refashioned as a pocket door. One of the pluses to living in New Orleans is it's easy to find lots of great old stuff like that. I'll send another photo in a week or so when we have the fixtures and vanity in—I couldn't be more excited. Not to all: the Pearl Gray is not super dark—it's much lighter in person than in the photos.

damsden1: All the tiles you chose are very cool. I'm a big fan of the square tile in running bond with grey grout--it looks fantastic!

It looks gorgeous! What tub did you use and what is the stone surround? What are the measurements of the stone around it and are there any seams?

Thanks! I'm just about done now, and can post some final photos if interested. Here's the tub: https://www.wayfair.com/Soaking-Drop-In-or-Alcove-30-x-60-Bathtub-BT104-BT%25C2%25A0-FINF1001.html. 

I chose it because it was two inches deeper than most, so ideal for baths but not a hassle to step into for showering. It was also a lot cheaper than a lot, mainly because it's acrylic instead of cast iron. My contractor packed the base with sand and insulation, so it "feels" super solid like iron, not plastic-y at all. I was constrained by a very small space, but would have gone a bit wider if I could. That said, for a single bather it's really a dream.

The surround is black soapstone, which is just awesome stuff. Tough, can be cleaned with anything, and like granite is totally solid, so it doesn't get etchings or anything. The more I use it, the better it looks. The surround roughly measures 32.5x67, with a 5 inch lip around 3 sides, and 11 inches in the back for where I can put shampoo and even sit down. No seams—had to buy a whole slab to get that look, but I used the inset for the vanity, so nothing was wasted.

If you had the space, I bet this one would be nice: https://www.wayfair.com/Soaking-Drop-In-or-Alcove-32-x-60-Bathtub-BT102-BT-FINF1004.html

And if you have the money, you can't beat cast iron. But it's two to three times more, and since I knew I was going to encasing the whole thing in stone, I didn't need for the tub itself to be so upscale.

Thanks for the information. I love soapstone! I used it for my kitchen counters and am trying to convince my husband that we should use it in our bathroom too. Would love to see finished photos!

Here's some I just snapped—not the best photos but you'll get the vibe. Still waiting on the p-trap in unlacquered brass to complete the vanity, which I made using cheap Ikea cabinets with custom reclaimed oak fronts. What you can't see is that the ceiling is super cool and high: it slopes from the shower up to 12 ft, with the original beams, boards, and even old knob and tube wiring exposed. It's a tiny space that actually feels quite spacious now.

They were the big splurge—totally the real deal, and absolutely worth it. It's all unlacquered so it gets that nice patina. Did the same in my kitchen for the pulls.
