Vinyl Plank Without Quarter Round: Ditch the Trim for This Flawless Look
You’ve just installed beautiful new vinyl plank flooring. The lines are clean, the color is perfect, but then comes the final step: covering the edges. For decades, the go-to solution has been quarter round molding, a simple trim piece that hides the necessary expansion gap between the flooring and the baseboard.
But for many homeowners seeking a modern, seamless aesthetic, quarter round can feel like a bulky afterthought. It breaks up the clean line from the wall to the floor and can detract from pristine new baseboards. The problem is, you can’t just skip it; that gap is essential to prevent your floor from buckling.

Why Quarter Round is a Design Dilemma
Quarter round molding serves a purely functional purpose: to hide the perimeter gap required for floating floors like vinyl plank. This gap, typically about 1/4 inch, allows the floor to expand and contract with temperature and humidity changes. Without it, planks can push against the walls and create unsightly bulges or separations.
While effective, quarter round often looks tacked on. It adds an extra horizontal line that can make baseboards look shorter and busier. For those who have invested in taller, more stylish baseboards, adding a curved piece of trim at the bottom can undermine the entire design goal, creating a finished look that feels compromised rather than intentional.
The Professional Secret: Ditching Trim Altogether
Achieving a clean edge without quarter round is not only possible, it’s the preferred method for high-end, professional installations. The secret isn’t in some special type of flooring but in the installation technique itself. The goal remains the same—to hide the expansion gap—but the method is far more elegant.
The key is to use the baseboard itself to cover the gap. This creates a direct, uninterrupted line from the wall to the floor. It’s a subtle detail that makes a significant visual impact, resulting in a cleaner, more modern, and spacious appearance.
The Best Method: Remove and Reinstall Your Baseboards
The most reliable and effective way to get this professional look is to remove your baseboards before installing the vinyl plank flooring. Once the flooring is laid, with the required expansion gap around the perimeter, the baseboards are reinstalled on top of the new floor. The thickness of the baseboard neatly covers the gap, completely eliminating the need for any additional trim.
Follow these steps for a perfect finish:
- Carefully Remove Baseboards: Use a utility knife to score the caulk line along the top of the baseboard. Then, gently use a pry bar—with a putty knife behind it to protect the wall—to pry the baseboards away.
- Label Everything: As you remove each piece, label it on the back with its corresponding location (e.g., “North Wall, Piece 1”). This will save you a massive headache during reinstallation.
- Install Your Flooring: Lay your vinyl plank flooring according to the manufacturer’s instructions. Be sure to use spacers to maintain a consistent 1/4-inch expansion gap around the entire room.
- Reinstall the Baseboards: Place the baseboards back in their original locations, resting them directly on top of the new flooring. Nail them into the wall studs, not into the floor, to allow the flooring to move freely.
- Finish the Job: Caulk the top edge of the baseboards and fill any nail holes. A fresh coat of paint on the baseboards will complete the seamless, professional look.
Alternative Method 1: Undercutting Baseboards or Drywall
In some situations, particularly with very thick or ornate baseboards you don’t want to risk damaging, undercutting is an option. This involves using an oscillating multi-tool or a jamb saw to cut away the bottom of the existing baseboard or drywall. The vinyl plank can then slide directly underneath.
While this can work, it requires extreme precision and can be messy. It’s often more difficult than removing and reinstalling the baseboards and carries a higher risk of damaging your walls or trim if not done perfectly. For most DIY projects, the remove-and-reinstall method is superior.
Alternative Method 2: Use Shoe Molding
If removing baseboards isn’t feasible, consider shoe molding instead of quarter round. Shoe molding is more rectangular and less bulky than the perfect quarter-circle of quarter round. It provides a more delicate and refined look while still effectively covering the expansion gap.
Shoe molding is a good compromise if you want a cleaner profile but cannot remove the existing baseboards. It offers a more subtle transition and is often seen as a more decorative and less purely functional option than its bulkier cousin.
Critical Factors for a No-Trim Installation
Forgoing quarter round leaves no room for error. Two factors become absolutely critical for a successful installation: a flat subfloor and straight walls. Without trim to hide imperfections, any issues will be immediately obvious.
A Perfectly Flat Subfloor is Non-Negotiable. Any dips or high spots in the subfloor can cause planks to flex or sit unevenly. This can lead to visible gaps between the bottom of the baseboard and the flooring. This is related to the question of how forgiving vinyl plank flooring is; without trim, its forgiving nature diminishes significantly. An uneven subfloor can also contribute to a bouncy feeling underfoot, as planks are not fully supported.
Straight Walls Are a Must. If your walls are wavy, the reinstalled baseboard will follow that wave, creating an inconsistent gap between the trim and the straight edge of your flooring. Before you begin, check your walls with a long straightedge to identify any major issues that might need to be addressed.
| Method | Best For | Pros | Cons | Skill Level |
|---|---|---|---|---|
| Remove/Reinstall Baseboards | New installations or renovations | Cleanest, most professional look; No extra trim needed | More labor-intensive; Risk of damaging trim during removal | Intermediate |
| Undercutting Baseboards | Installations where baseboard removal is not possible | Hides gap without removing trim | Requires precision tools; High risk of damaging baseboards or walls | Advanced |
| Shoe Molding | Covering gaps without removing baseboards | More elegant than quarter round; Easy to install | Still adds an extra line; Not as clean as no trim | Beginner |
| Quarter Round | The quickest and easiest solution | Effectively hides large or uneven gaps | Can look bulky and dated; Detracts from clean lines | Beginner |
What About Glue-Down Vinyl Plank?
It’s important to distinguish between floating vinyl plank and glue-down vinyl plank. Glue-down LVP does not require an expansion gap because it is fully adhered to the subfloor. This stability means it won’t expand or contract significantly.
With glue-down vinyl, you can install the planks directly against the baseboards for a seamless look without any special techniques. However, proper subfloor preparation is even more critical, as any imperfections can affect adhesion. Issues can arise, for example, when installing over old adhesive, which can compromise the bond of the new floor.
Frequently Asked Questions
Is quarter round necessary for vinyl plank flooring?
No, quarter round is not always necessary for vinyl plank flooring. It is primarily used to cover the expansion gap left around the perimeter of the room. If your baseboards are thick enough to cover this gap, or if you use other finishing methods, you can achieve a clean look without it.
Why is there a gap between the vinyl planks and the wall?
An expansion gap is required for most vinyl plank flooring, especially floating floors. This space, typically 1/4 inch to 3/8 inch, allows the flooring to expand and contract with changes in temperature and humidity without buckling. Failing to leave an adequate expansion gap is a common installation mistake.
What can I use instead of quarter round for vinyl plank flooring?
There are several alternatives to quarter round for a modern finish. Shoe molding is a popular choice that is less bulky than quarter round. Other options include using taller baseboards that cover the expansion gap, or applying a flexible, paintable caulk for a seamless look.
Can I install vinyl plank flooring without removing my baseboards?
Yes, you can install vinyl plank flooring without removing existing baseboards, and this is often done to save time. In this case, you will need to leave an expansion gap and cover it with a trim piece like quarter round or shoe molding. For a cleaner, more professional appearance, removing the baseboards before installation is recommended.
How do I hide the expansion gap without using quarter round?
To hide the expansion gap without quarter round, you can install the vinyl plank flooring first and then install new, thicker baseboards on top to cover the gap. Another method is to carefully cut the flooring to leave a minimal, consistent gap and then fill it with a flexible caulk that matches the floor or baseboards. Some people also opt for shoe molding, which is slenderer than quarter round.
The Final Verdict: Is It Worth the Extra Effort?
Skipping quarter round in favor of a cleaner installation is absolutely worth the effort for anyone seeking a modern, high-end finish. While it requires more work upfront—specifically, removing and reinstalling your baseboards—the result is visually superior.
By using your baseboards to hide the expansion gap, you create a seamless transition that makes rooms feel larger and more polished. It’s a hallmark of a thoughtful, professional installation that elevates the entire space. Don’t settle for the easy way out; take the extra step to give your new floors the flawless edge they deserve.
