If you've ever spent hours laying down a new floor only to find a "lip" sticking up the next morning, you probably need some lash 1 8 leveling clips in your toolbox. There is nothing more frustrating than finishing a long day of tiling, stepping back to look at your work, and realizing that one corner of a tile is sitting just a hair higher than the one next to it. It's called lippage, and honestly, it's the bane of every DIYer's existence.
I've been there. You think you've pressed the tile down enough, you've eyeballed it from three different angles, and you're sure it's flat. Then the thinset dries, it shrinks just a tiny bit, and suddenly you've got a toe-stubbing hazard right in the middle of your kitchen. That's exactly where these clips come into play. They take the guesswork out of the equation and make sure everything stays exactly where you put it while the adhesive sets.
What are these things anyway?
If you're new to the tiling world, you might be wondering what the "lash" part even means. It's basically a two-part system designed to hold tiles at a consistent height. You've got the lash 1 8 leveling clips, which are the clear or white plastic pieces that look like a little window or a stirrup. These go under the edge of the tile. Then you have the reusable wedges (usually yellow or red) that you slide through the clip to lock the tiles into a perfectly flat plane.
The "1 8" part is pretty important too. That refers to the thickness of the clip's base, which automatically sets your grout line to 1/8 of an inch. It's a bit of a two-for-one deal because you're leveling the tiles and spacing them at the same time. You don't have to fiddle with those tiny little rubber crosses that always seem to fall into the wet mortar.
Why the 1/8 inch size is the sweet spot
Choosing a grout joint size can feel like a big commitment. If you go too wide, it looks dated. If you go too thin, any slight imperfection in the tile shape becomes super obvious. Using lash 1 8 leveling clips gives you that classic, clean look that works for almost any project.
It's wide enough to handle slight variations in tile size (because let's be real, even expensive tiles aren't always perfectly square) but narrow enough to look modern and sleek. It's especially great for those large-format tiles that everyone loves right now. When you're working with a 12x24 or a 24x24 tile, the weight of the tile itself can cause it to sink into the thinset at different rates. The 1/8 inch clips keep those big boys in line.
Getting the hang of the installation
Using these clips isn't rocket science, but there is a bit of a rhythm to it. First, you spread your thinset like you normally would. After you lay your first tile, you slide a few lash 1 8 leveling clips under the edges. You usually want them a couple of inches away from the corners.
Then, you set your next tile right up against the clips. Once the tiles are in place, you take the wedge and push it through the loop of the clip. You can do this by hand, but if you're doing a whole room, your thumbs are going to hate you by the end of the day. Most people use a pair of specialized pliers that come with the system to cinch the wedge down tight.
The magic happens right here. As the wedge tightens, it pulls the lower tile up and pushes the higher tile down until they are perfectly flush. It's incredibly satisfying to watch. You can actually feel the tiles snapping into alignment.
A few mistakes to avoid
I've learned the hard way that you can't just set these and forget them. One big tip: make sure you don't leave a bunch of thinset squeezed up into the clip. If the mortar dries around the plastic, the clip won't break off cleanly later. I usually keep a small margin trowel or even an old toothbrush handy to quickly swipe out any excess "goop" from around the lash 1 8 leveling clips before I move on to the next section.
Another thing to keep in mind is the "kick-off" phase. You have to wait until the thinset is completely dry—usually 24 hours. If you try to remove them too early, you might actually pull the tile up or shift the position. Once it's dry, you just give the clips a sharp kick with your boot or hit them with a rubber mallet. They're designed to snap off right at the base, leaving the bottom part buried under the tile and out of sight.
Are they worth the extra cost?
Look, tiling is already expensive. Between the tile itself, the mortar, the grout, and the tools, the budget can spiral pretty fast. You might look at a bag of lash 1 8 leveling clips and think, "Do I really need to spend another thirty or forty bucks on plastic bits?"
In my opinion? Absolutely. If you're a professional, these save you so much time that they pay for themselves in labor. If you're a DIYer, they are essentially "mess-up insurance." Replacing a single tile that's set too high is a nightmare. You have to chip it out without breaking the surrounding tiles, scrape up the old mortar, and try again. It's a huge mess. Spending a little extra on a leveling system is way cheaper than a redo.
Real-world results on walls and floors
While most people think of floors when they talk about lash 1 8 leveling clips, they are a total lifesaver for walls too. Think about a bathroom shower. Gravity is constantly trying to pull those tiles down while the thinset is wet. These clips help hold everything in place so you don't end up with sagging rows or uneven corners.
I used these on a kitchen backsplash recently with some heavy porcelain tiles. Usually, keeping those things level while working around outlets is a massive headache. But with the clips, I could lock each tile to its neighbor. It gave me a lot more confidence that the final product was going to look professional, even though I'm just a guy with a weekend project.
Final thoughts on the process
At the end of the day, tiling is about 20% inspiration and 80% preparation. Using the right tools makes the 80% a lot less painful. The lash 1 8 leveling clips don't just give you a flat floor; they give you peace of mind. You don't have to wake up in the middle of the night wondering if that one tile in the corner is sloping.
If you're planning a project soon, definitely pick up a pack. Just remember to buy more than you think you need. There's nothing worse than being three tiles away from finishing a room and realizing you've run out of clips. Plus, the wedges are reusable, so once you have a set of those, you only ever have to buy the clips for your next job.
It makes the whole experience feel less like a high-stakes gamble and more like a controlled project. And when you finally walk across that floor in your socks and don't feel a single bump? You'll be glad you used them. It's those little details that turn a "decent" job into something you're actually proud to show off to your friends.
