Looking for the best grout colors for subway tile or marble? See gray grout colors in real spaces to help you choose!
A dear friend is currently remodeling her master shower. This – and our ability to enjoy any excuse to chat š – led to a long discussion regarding tile and grout. While this may not sound like the most riveting of topics, any person who is in the middle of a renovation can tell you that it’s an important one! So I decided to put together a little guide on choosing grout colors.
I realized when writing this that I have now been renovating kitchens and bathrooms with white and marble tile for fifteen years (and longer if you remember and count the story from my childhood home)… So if you’re considering that classic look, I hope you find these options helpful!
Grout Color FAQs
Should I use white or gray grout?
This is obviously a personal preference… but my answer is still gray. Always gray. Why? Because I cannot keep white grout white. I’d like to be able to because I do love the look of white tile with white grout; it allows the texture of the tile and grout to shine. But keeping white grout white just feels impossible to me, so I always prefer gray.
What color grout looks best with white subway tile?
White subway tile with gray grout is such a classic look. Fortunately, there are many beautiful options! You can use light gray or dark gray, warm gray or cool gray… See below for exact brands and colors with pictures!
What color grout looks best with marble?
Choosing a grout color for marble tile can be a little tricky because natural stones always have potential variations. But generally speaking, I think a light to medium gray that blends with some of the natural variations of the stone is best. Again, see below for exact brands and colors with pictures.
How big should grout lines be?
I realize this isn’t exactly a grout color question, per se. But the size of grout lines affects the impression that the color makes… And everyone seems to ask this question anyway, so I’m answering it. š
My go-to grout line size is 1/8″. I find it is small enough to keep the grout feeling minimal, but large enough to have uniformity. I have sometimes used other sizes, certainly, but this is probably what I use for 90% of projects these days.

Best Gray Grout Colors for Subway Tile and Marble
White Tile with Gray Grout
I actually have two favorite medium to light grout colors to share with you: one warm and one cool. Either can be paired with marble, too, as you can see in the images below. I choose warm or cool depending on the surrounding colors (cabinetry, walls, etc.). See here for more thoughts on warm and cool colors.
Favorite warm gray grout for white ceramic tile: Mapei Warm Gray grout (all in one grout replaces both sanded and unsanded)
Favorite cool grey grout for subway tile: Polyblend Platinum sanded grout or non-sanded grout
White Tile with Dark Gray Grout
For a more dramatic appearance, consider a more contrasting grout. Dark gray grout provides a classic yet modern look.
Favorite dark gray grout for white tile: Delorean Gray grout in sanded or unsanded
Marble Tile with Gray Grout
Given how often I like to mix marble and white ceramic tile, it’s probably not too surprising that my favorite light colored grout for marble tile is the same as my favorite grout for subway tile.
If I had to choose just one, I think the cooler gray, the Polyblend Platinum, looks especially beautiful with Carrara marble. I used Platinum grout for our marble backsplash in our kitchen as well as our Bianco Carrara master bathroom.
Favorite cool grey grout for marble: Polyblend Platinum sanded grout or non-sanded grout
If your space calls for a warm gray, though, then never fear. The natural variations of white and gray marble lend themselves to warm tones, too. I used a warm gray grout on our tumbled marble floor tile in my girls’ bathroom and love the result.

Marble Mosaic Tile with Gray Grout
Speaking of mosaic marble floor tile, I haven’t shared this project yet (so please forgive the in-process iphone shot!), but we also used Mapei Warm Gray for these geometric mosaic tiles. I love how the shape of the tiles is highlighted by using a color that is slightly lighter than the gray marble.
Update: see the full finished bathroom here.
In short, here are my favorite grout colors for white subway tile and marble:
- warm light gray: Mapei Warm Gray
- cool light gray: Polyblend Platinum
- dark gray: Polyblend Delorean Gray
I hope you found this helpful! Be sure to pin it for your next renovation.
Do you ever recommend/not recommend marble mosaic tile with white grout? In what cases? Thanks!
White grout is beautiful, but it is hard to keep clean. That is why I prefer gray for most circumstances. Hope that helps!
Everything I’ve read, as well as marble installers tell me darker grout will stain white marble tile where it touches. I would love to use black grout but don’t want to ruin my tile for the future. Any experience with that…or long term adverse reactions?
I have heard that dark grout can stain marble. I don’t have any experience with this myself, but I would be wary of it… If it’s really the look you want, you might consider a more gray Carrara (rather than a bright white marble) so the color different wouldn’t be as stark. I wish I had a better answer for you!
Hi! What color/size grout do you like with an all white marble like thassos going on the walls? My bathroom already has a carrara marble floor purchased, so I would have to take that into consideration.
I still like warm gray or platinum for all tile going in bathrooms because I think it’s more forgiving than white grout. š But the grout will look darker against the thassos than against the Carrara, if that makes sense. If you want it to blend more, you could look for a soft white grout for the walls and use platinum or warm gray for the floors. I hope this helps!
Is there any chance you can comment on āFrostā by Mapei for my Carrera shower walls. I really think I would like the grout lines to disappear and this color has been suggested to be. Or is there any other color that would blend the most and disappear ?? Thank you !!!!
Frost is a great color! I have a friend who used frost with her marble shower floor and it looks fantastic! Highly recommend!
Thank you so much !! Actually changed my mind to the Platinum today and I think itās going to look fantastic !! I was concerned that it might be too dark but it actually blends with the Carrara perfectly and ties in with the floor color as well !!!
Wonderful! It’s funny with Carrara. Since it’s natural stone, it really depends on how gray your actual pieces are whether platinum or frost is a better match. So glad you found something you love!
Well now Iām having second thought again since I think my tile job is not perfect and I want the lines to disappear. Are there any other very pale grays you could recommend ?? Had the tile job been perfect, I would have gone w platinum :((((
Can you remind me what you tried? White with white tile would be the best at hiding imperfections.
My walls are Carrara marble. Unfortunately, there are some imperfections w the grout lines so I want them to disappear as much as possible. I think the Platinum is beautIful but Iām afraid it will draw too much attention to the lines. Mapei Frost seems to have a bit of a yellow cast. What I really want is a pale, pale gray to blend with the primary stone color , not the veining.
I have personally seen frost and it doesn’t cast yellow for me. It is a light gray and might be a great fit for you!
Recently did a remodel of our kitchenā¦. we went with white cabinets, white, shiny
3āx9āsubway tile and white grout. Ugh, too much white! And (as you mentioned) the grout is turning a little yellowish. Trying to work with Revere Pewter paint on walls – and they appear much more beige then gray in this kitchen. Have been playing around with grout pens – dark is too stark, med. gray seems ok but may seem like too much if itās everywhere, and winter gray doesnāt go well with the Revere Pewter. Please helpā¦. which grout will work? Maybe itās time to just move, lol.
Hi Jen! Revere Pewter is a warm beige, so a warm gray grout color might be your best bet!
Hello,
Remodeling a bathroom with SW Sea Serpent vanity and white subway tile. I need a wall color and grout choice. I love the wall color in your pictures featuring the navy vanity. Do you know what color it is? I am leaning toward warm grey grout with a matching wall color. The other grout color Iām considering is silver but am afraid it might be too dark.
Hi Ann,
The wall color featuring the navy vanity is SW Snowbound, a beautiful crisp white. I’d recommend a warm gray grout, it’s a great color choice for grout for cleaning and classic warmth.
Thank you! You think the warm grey is enough of a contrast? Iām so worried it might be too light. (Although at this point I already told contractor warm grey). Can I go wrong with the warm grey????
It’s one of my favorite applications for most grout installations, so I think it’s generally the right choice.
Hello, one more thing. Installer is using Mapei Ultra Color Plus FA. Is that what you use? Are Mapei colors consistent across their various formulas?
Yes! That’s a great grout brand. They are pretty consistent that I have seen.
Hi Rachel, I am struggling to choose which grout color to go with. I love the idea of clean white on white but like you said will struggle to keep it clean. So I have been thinking really thin and dark to go with my 3×12 white subway tile. My cabinets are going to be olive green and I am leaning towards a callacata trevi white quartz. I have a farmhouse sink, faucet and pulls will be black but lots of stained wood accents including open shelves with the tile around it. Trying to give you all the details to give me your opinion on what direction I should go. I like the gray I just wondered if the dark would be better with the dark and wood accents. Thanks for your help!
White grout, while beautiful, is a difficult choice with food and water stains. A warm gray would be beautiful in this option. It will honestly blend in and let the tile design shine!
Hi there, I love your work! Do you have any issues keeping Platinum grout clean in showers or on floors? Iām leaning towards Delorean just for up keep purposes but I love the cleanness of a lighter color . thanks!
I don’tāespecially as a busy family of 6! Be very careful with bleach cleaning products as they can lighten the grout color. I like a product called Simple Green.
Love your home & blog! I am currently installing a honed carrera marble kitchen backsplash. I know you love Platinum , however, when I did a sample of platinum on my marble tiles, it turned the edges a slight gray all around and wouldnāt come off. Question: Would you ever recommend Arctic White as a possible grout to use with the honed carrera marble? Wondering if the white may look nice too. Thank you for your help!
White is a difficult color for grout especially in the kitchen due to food stains. Have you tried a lighter gray? Frost could be a good choice.
Hi! I love the platinum grout but my builder uses TEC. Do you happen to know what would be the equivalent color in that brand of grout? Thanks!
I don’t, but if you find a stockist for both, I bet you could find the right match in person.
I am doing a 3āX3ā hexagonal tumble marble on the floor. I budgeted for a simple white subway tile for the shower surround. What size subway tile would you recommend? 3āx 6ā or 3ā x 8ā?
Thank you
Judy
I’ve used 3×6 for a traditional, classic look!
Hi! I have the berwyn countertop color from cambria, benjamin moore pale oak walls, white subway tile in kitchen floor to ceiling in some places. Agonizing over grout color! Want light and bright but . ….
Will warm grey be too dark for a small kitchen in an open floor plan? The pale oak walls adjoin, again, my kitchen and living room are essentially the same small space.
Thx
Is there any chance you could share how Prism brand grout in “Bleached Wood” translates? I have an open concept and was thinking about using it for my Bedrosians Cloe backsplash and hexagon tile surrounding the fireplace that looks very similar to the one shown above with the gray grout. I feel like they should have the same grout since it’s open concept and can’t decide if it’s too dark. I want a light, warm feel.
Hi Elizabeth! I don’t have an example in that grout color, but sometimes a quick Google search might show some results with that tile. I do love that tile option!
Hi, I recently bought wavy, textured white subway tiles, white cabinets, and a white granite countertop with light gray veining and black flecks. I went with a white theme overall because I have a very busy tile floor that Iām not replacing at this time. I would like a gray grout. Iām torn between Mapei Warm Gray and Delorean Gray. I donāt want a stark, busy contrast, nor do I want something too light. I also donāt want the tiles to look too busy because the ābossā in the room is the kitchen floor tiles. I have painted the walls a pale warm gray. Any advice?
I really love warm gray for this application. It blends in and brightens the space without looking busy.
I was in the same situation and took Rachelās advice and went with Mapei Warm Grey. Itās perfect. In my opinion it looks darker than the sample grout stick I had. Love it.
Love it!
