Groutless Tile Installation: Can You Tile without Grout?

Here’s an age-old question: can you do a groutless tile installation? Well, the short answer would be a simple no – you should not attempt to install tile without grout.
Why’s that, you might wonder.  It’s not like grout adds to the stability of the tile installation (unless we talk about a few exceptional cases) so why is grout necessary?

Simply put, various natural materials, such as stones, are manufactured for use with a pretty consistent size. Not to mention, most of them look identical. That is why a newcomer’s first instinct might be to install them without grout lines.

There is also the argument that groutless tile installation simply looks better and makes the work seem more compact or put together. Still, experienced contractors will tell you that this isn’t a good option, and even the thinnest of grout lines can make a big difference.

Understandably, most installers have a love-hate relationship with grout. It takes up a lot of time, and it requires meticulous work. There are cases when laying tile without grout will probably leave the job looking a lot better.
But here’s the thing: if you want the job to last, then you need to use grout. Groutless tile has a higher chance of breaking, meaning that you would need to resume the work.

With these considerations in mind, this article will discuss some of the reasons tilling without grout is an ineffective method and why you should stick to the traditional practices.

Tiles Are Not Identical

Your tiles might look like they have the same size, but chances are they don’t. The differences could be relatively small and impossible to notice without measure, but they can interfere with the groutless installation process. When you put the tiles together, those tiny irregularities will add up, making the final result look a bit off and unprofessional. The last thing you want after you’ve worked for hours to install tiles is to notice that they are not aligned properly.

Grout allows you to mask the differences in tile sizes and control the outcome. In fact, even the smallest lines can make the tiles fit perfectly with one another, giving the final result a nice symmetrical look.

Material Might Get Caught Between Tiles

Regardless of the size of the project, certain elements might get between your tiles if they are not grouted. It can be dust, dead cells or other debris that will find a way between your tiles no matter how compact you think the installation looks. Grout can prevent such scenarios.

You can spend hours putting the tiles together and be pretty satisfied with the result. But without grout, there will always be a tiny space between the tiles that acts like a magnet waiting to attract debris. In time, these small differences between the tiles will have gathered enough dust and debris to ruin the entire ensemble.

Don’t assume that you can just clean the tiles after the installation process is over. That can prove to be quite a difficult task because even the slightest mistake is enough to damage one of the tiles and require you to work more than you’ve initially planned just to fix the error.
One of the easiest ways to avoid this nightmare scenario: you’ve guessed it – use grout when you install tiles.

Yes, They Move

Another reason you should reconsider the entire concept of groutless tile installation is that tiles move. Because the edges of the tiles will continuously rub against each other, they are likely to chip or even break at some point. Which, let’s be honest, is not ideal.

Sure, there are other tips and tricks you can use, but they only minimize the impact and don’t stop the tiles from moving and rubbing against each other. Grout, on the other hand, acts as a buffer and prevents the tiles from making contact while they expand or contract.

What You Can Do

It’s not all bad. After all, grouting is like the biggest, most impressive scene right before the grand finale. It’s the last step of your tile installation process. At the end it even completes the entire look for your work. It is the key difference between tile work that stands the test the time and those that end up in need of tweaks.

Grouting Tile - Don't Do Groutless Tile Installation

Above all, remember what the ANSI specification says about the minimum grout joint size (A108.02-4.3.8):
“To accommodate the range in facial dimensions of the tile supplied for a specific project, the actual grout joint size may, of necessity, vary from the grout joint size specified. The actual grout joint size shall be at least three times the actual variation of the facial dimensions of the tile supplied. Example: for tile having a total variation of 1/16″ in facial dimensions, a minimum of 3/16″ grout joint shall be used. Nominal centerline of all joints shall be straight with due allowances for hand-molded or rustic tiles. In no circumstance shall the grout joint be less than 1/16″.
The biggest issue you might face with the process of grouting has a lot to do with getting the right thickness for the mix or having it dry solid before you even get the chance to use it.

What about Rectified Tiles?

You might have heard about rectified tiles and wondered if these mechanically cut materials don’t require grout for the installation.

So, is that true?

Rectification is a mechanical process that requires milling the edge of the tile at a specific angle, which suggests that the materials will have the same size. As such, you can install them without worrying that the final result will look unaligned and unprofessional. That happens because this process allows you to cut each tile to the same size, with an accuracy of 0.2 mm. Rectification works for both floor and wall tiles.

Tiles that have gone through this process are popularly believed to be freed from the necessity of grout because of their nearly identical size and perfectly cut edges. However, that is not exactly the case.

Even if rectified tiles allow you to avoid using grout without having the result look unaligned, the materials are still in danger of being chipped or damaged. Perfectly cut edges will not perform better than regular tile when friction occurs, so they can still cause a variety of problems if you opt for a no grout tile installation.

In truth, rectified tiles allow for a thinner grout line. But, the misconception that they can go groutless might leave your work looking unprofessional. Rectified tiles still very much rely on grout if you want them to withstand the test of time. However, you’ll find that their grout lines can be a lot harder to notice in the case of these rectified tiles.

The Sanded vs. Unsanded Debate

Most specialists have a pretty good understanding of the differences between sanded and unsanded grout; therefore, we won’t go into too many details.

Sanded and unsanded – these are the two most common grouting materials. It’s not a debate per se, but you need to be able to choose the right grout for your type of work to properly complete the job. We’ve mentioned that grouting your tiles ensures that your work will be long lasting. Well, having the right grout material for the right type of work also plays a major role in the success and durability of your project.

Use unsanded grout for lines smaller than a ⅛ inch wide since it will shrink as it dries. If you’re working on vertical surfaces, you’ll find that it’s a lot easier to use unsanded grout for wall installations, given that it is a lot stickier than other materials. As a result, it won’t fall off as you try to fit it into the grout lines.

Sanded vs Unsanded Grout

On the other hand, sanded grout will work better for wider grout lines. If the name’s not a good enough clue, know that this material has fine sand added to stop it from shrinking as it cures. Though it can be used in smaller grout lines just as well, it’s a lot easier to apply it to larger lines.

However, with sanded grout, you also need to pay attention to the type of tile material you’re using. In some cases, sanded grout might not react positively with these materials as the sandy texture can scratch the tiles. Make sure to test it before using it to check if the mixture will scratch the surface of the tiles.

In a Nutshell

Yes, it’s technically possible to do a groutless tile installation, but as the article pointed out above, it’s not exactly worth it. There are three main downsides to skipping the grout when installing tiles:

  1. If the tiles are not identical, they will appear unaligned;
  2. Dirt can get beneath them and damage them in the long run;
  3. Movement can lead to breakage.

So what happens if one of your clients insists on skipping the grout? Well, you should try to talk them out of it. Of course, in the end, it’s their decision to make, but try to help them understand why grout is important. Some might desire a compact look, and think the grout simply disrupts the pattern of the tiles. Try to make them see that the benefits of grout will ultimately serve them in the long run. After all, it’s very likely that many will prefer choosing something that lasts longer, rather than opting for a few months of “looking pretty.”

  1. Hey, I think your website might be having browser compatibility issues.
    When I look at your website in Ie, it looks fine
    but when opening in Internet Explorer, it has some overlapping.
    I just wanted to give you a quick heads up! Other then that, great blog!

  3. If this can be wooden then eventually this can start to rot causing difficulty
    with your roofline. You can try to remove it
    manually, but between the time it takes and the risk of hurting yourself along with the tile, this
    can be one region where receiving a professional intend
    to do it makes a lot more sense. As with nearly all troubling situations in daily life prevention is obviously better than a
    cure and so it can be with tile cleaning as well.

  4. I have glass tile with beautiful beveled edges in the store I did not see grout between each piece. Does the same go for glass

    1. You ALWAYS need to use grout. You’ll have to work carefully in this case because it can be difficult to get the grout inbetween beveled corners.

  5. My kitchen guy was telling me that he has grouted the tiles to the walls and no grouted between tiles as it’ll give a seamless effect and insisted on no grouting between tiles on the splashback. He said splashback is ok. Is this true?

    1. It’s not what we recommend. The better way to do it would be by spreading adhesive on the wall, laying the tile onto the adhesive with spacers and levelers, and then grouting between the tiles. This is the more common way of laying any tile installation, including on a wall.

  6. Got guys in tiling bathroom.
    Using spacers horizontally but none vertically so tiles butt up to tiles yet need grouting horizontally!
    These are two experienced builders here, am I to question them?

    1. Hi Mike. That’s hard for us to say without seeing their work in person. But you are the client. You have every right to ask what they are doing, how they are doing it, and why they are doing it that way. Just be polite and honest about your question. They are professionals. If they are good at their job they will be able to tell explain what they’re doing.

  7. We let them install our tiles without grout and were assured that they would fit so tight together that grouting wasn’t needed. Looked beautiful for about a day then wow, what a mistake!!! Every-day dirt got in there and it’s awful. Does anyone know a way to fix this? Thank you!

    1. Hi Marilyn. If the tiles are layed too close together to fit grout inbetween them, then you’ll have to de-install them and start over… Sorry they did your installation so poorly.

  8. My wife and I were assured by the fabulous designer at a certain f&d store that the glass subway tiles could be installed without grout. After reading the previous comments and replies, we’ve decided to use grout, but would like to keep the tiles with the smallest space possible. Any suggestions on the minimal spacing size and the type of grout that would work best. It is a wall next to a soaker tub. Thanks, in advance.

    1. Hi Craig. We’re glad you read our blog. It would have been a disaster in the long run to install your tiles with no joints at all. In your case, the smallest grout joint we’d recommend is 1/16 inches. If you want to keep your tile installation looking as close as possible to how it would with no grout at all, maybe using *transparent* grout will help you achieve that look.

  9. The tiles I have are very thick and look like old barn wood planks. Using grout would make them look like tiles. No grout and it would look like an authentic wood floor. Suggestions?

    1. Hello Phill. Any tile installation requires a grout joint. If you don’t have grout joints between your tiles, they will crack and chip very quickly and your tile installation won’t last very long and won’t tolerate the wear and tear of being walked on. A grout joint between 1/8 and 3/16 of an inch should be fine for most wood-look tiles. You can also use a black or brown colored grout so that it doesn’t look as noticeable.

  10. I had a tile floor put in my 14′ x 14′ study in 2012 with zero grout. I wanted a more contemporary look. The tile I bought said it was precision cut for that option. 10 years later it is still perfect. It was put over a slab floor by a professional installer. So I was under the impression that this is a normal option. After reading a lot of horror stories about it, it would make me think twice about doing it again. Thanks for the warnings. FYI, the temperature range has even exceeded 40 F and no broken tiles.
