Fix that thin gap between your cabinets and the floor with this quick and easy DIY update!
If you have a thin gap between the cabinet toe kick and the floor, like mine. There’s a super easy fix for that! A thin bead of caulk can fill a small gap under cabinets in less than 30 minutes. YASSS! I love a quick win, guys!
This DIY works on gaps 1/2″ and smaller. But, if your gap is larger than a 1/4″, you should use trim first, like quarter round. It’ll look much better than a larger bead of caulk.
Now, I realize some people probably wouldn’t worry about a gap this small. It isn’t something that jumps out at you when you’re in the room. But it definitely annoyed me. In fact, I’ve wanted to take care of this since our big kitchen remodel. I kinda mentioned the tile and toe kick issue in my 80+ tips for building or planning a remodel. I like to get rid of that gap because it tends to attract crumbs and spills.
Filling any small gap under cabinets in the kitchen, bath, and laundry means you don’t have to worry about dirt and sticky liquids collecting there. My boys even managed to slide a puzzle piece across the room and under our cabinets once. They were so sad that mommy couldn’t get it back out. Now it’s just a hidden treasure that someone will find someday. 😉
After filling this gap under our cabinets our kitchen feels refreshed and more finished. Maybe next weekend, I’ll have to apply my favorite grout renew and sealer in a few spots. The grout is looking pretty grungy in front of our coffee maker. I’ll try a quick scrub first, but if that doesn’t work, I know applying grout renew in my original grout color will make it look new again. I shared DIY steps and a short video of me using this in our bathroom, last summer.
Fall 2019 UPDATE: I did this grout refresh update on my kitchen floor. Here’s my YouTube video showing exactly how I used this product to brighten and seal the grout in our kitchen.
OK, let’s get this DIY to fill the small gap under cabinets in your kitchen, laundry, or bathroom started!

Easy DIY Steps to Fill the Small Gap Under Cabinets
Please Note: Pick a color that matches your cabinets. If you can’t find one, then picking a caulk that matches the grout tile might work. Just use your best judgement before you apply it. Color Fast makes a line of Caulk in a huge variety of colors too.
Wipe down the cabinets and floor with a simple cleaner and degreaser. Dawn in hot water should work. Then wipe that dry with a cloth.
Once dry, tape off the smallest gap possible with Painter’s tape. You want the tape on the floor to be directly beneath the cabinet toe kick, but not under it. And keep just a hair of cabinet toe kick showing for the top tape line. Make sure you tape all connecting cabinets in one go. Applying tape to a new section next to wet caulk would be pretty messy. 🙂
Apply a light bead of caulk across the entire line.
Use your finger to spread the caulk across the whole line. You want it to have a smooth look. It also needs to not be too thick or too thin. Just evenly fill the crack without creating a bubble or hump of caulk. Wipe excess from your finger onto a wet cloth or paper towel.
Once the line is smooth and completely filled, you can remove the tape. Make sure you remove that tape before the caulk dries.
Leave that caulk to dry. Caulk shrinks a tiny bit after drying. If, after 24 hours, you have a small gap in a spot or two, just tape off that section and apply a 2nd round of caulk.
That’s it. You’ve just blocked off that crumb and spill eating eye sore that was driving you crazy. 😉 Nice job!!
