Vertical Shiplap vs. Horizontal Shiplap: Choosing the Right Style for Your Space

When considering shiplap for your home, one of the first design decisions you’ll face is whether to install it vertically or horizontally. While both orientations offer classic charm and visual interest, they each contribute a distinct feel to a room. Understanding these differences can help you select the perfect option to complement your existing decor and achieve your desired aesthetic, whether you’re aiming for a cozy farmhouse look or a sleek modern finish.

When to Choose Vertical Shiplap

If your interior design style leans towards modern, contemporary, or even transitional aesthetics, vertical shiplap is an excellent choice. Its clean, linear lines create a powerful sense of height, drawing the eye upwards and making ceilings appear significantly taller than they are. This visual trick is particularly beneficial in rooms with lower ceilings, compact spaces, or areas like the powder room in this project, where maximizing the illusion of openness is a key design goal. Vertical shiplap also offers a sophisticated, tailored look that feels fresh and updated, subtly moving beyond the traditional farmhouse association often linked with shiplap. It can beautifully complement minimalist designs, coastal modern themes, or even industrial-inspired interiors by providing subtle texture and architectural interest without overwhelming the space. Consider it for an elegant and expansive feel.

When to Choose Horizontal Shiplap

For those who prefer a more traditional farmhouse, rustic, or classic coastal design, horizontal shiplap is typically the go-to choice. This orientation is widely recognized for its ability to evoke a sense of warmth, coziness, and historical charm, reminiscent of classic seaside cottages or rural barns. Beyond its aesthetic appeal, horizontal shiplap has a practical design advantage: it can make narrow rooms appear wider. By leading the eye horizontally across the wall, it expands the perceived width of a space, making it feel more open and expansive. This technique is often employed in hallways, entryways, or smaller bedrooms to create a more balanced and inviting atmosphere. While still a timeless choice, it’s worth noting that shiplap has evolved, and vertical application brings a distinctly different, often more current, vibe to home decor.

Having embarked on numerous shiplap installation projects since the inception of this blog over six years ago, we’re certainly no strangers to working with this versatile material. However, it had been a little while since our last shiplap endeavor. Our style, like many design trends, has evolved from a more rustic farmhouse aesthetic that was popular in our previous home. Today, shiplap has expanded far beyond its original farmhouse roots. By simply orienting the shiplap planks vertically, it instantly acquires a more modern appeal, seamlessly blending with a wide array of decorating styles – precisely the sophisticated yet relaxed vibe we aimed for with the California Casual powder room. This fresh take on a classic material allows it to feel both contemporary and enduring.

Step-by-Step Guide: How to Install Vertical Shiplap Wainscoting in Your Bathroom

Installing vertical shiplap wainscoting is a fantastic way to introduce architectural detail and elevate the style of your bathroom. This project can be adapted for a full wall application or as wainscoting (half wall), allowing you to customize the look to perfectly suit your vision. For this tutorial, we’ll focus on creating beautiful vertical shiplap wainscoting, a popular choice for adding character without overwhelming smaller spaces and making them feel more grand. Follow these detailed steps to achieve a professional finish.

Essential Supplies and Tools for Your Shiplap Project

Before you begin, gather all your materials and tools. Having everything on hand will ensure a smooth and efficient installation process, minimizing interruptions and frustration. Quality tools and materials can make a significant difference in the final look and durability of your project, so invest wisely where possible.

• 5″ Shiplap Boards: We highly recommend pre-primed shiplap tongue & groove boards, like those readily available from Home Depot. The pre-primed aspect saves a considerable amount of time and effort during the painting stage, as it eliminates the need for a separate priming step. The tongue & groove design makes assembly straightforward, ensuring a tight, consistent fit between planks.
• 1×2-1/2″ MDF Craftsman Moulding: This will serve as your upper rail, providing a clean, finished edge to the top of your wainscoting. It adds a touch of classic trim detail.
• 1×4-1/2″ MDF Craftsman Moulding: Used for the lower rail or baseboard, this wider piece helps create a substantial and polished foundation for your shiplap, enhancing its visual impact and protecting the bottom edge.
• Construction Adhesive: Such as Liquid Nails. For vertical shiplap, construction adhesive is absolutely crucial as you cannot reliably nail every board into a wall stud. We’ve found this particular type to be exceptionally strong and reliable, providing the necessary long-term hold.
• Caulk Gun: Essential for applying construction adhesive and caulk neatly and efficiently. Choose one with a smooth trigger action for better control.
• Cordless Finish Nailer: A finish nailer will significantly speed up the installation process and leave much smaller nail holes compared to a traditional hammer, resulting in a cleaner finish that requires less wood filler.
• 1 1/2″ Finish Nails: The standard size for securing shiplap boards and trim pieces with a finish nailer.
• Tape Measure: For accurate measurements – “measure twice, cut once” is the golden rule!
• Pencil: For marking cuts, guidelines, and electrical cutouts.
• Jigsaw: Indispensable for making intricate cutouts around outlets, switches, and other wall obstacles. A fine-tooth blade will yield cleaner cuts.
• Power Drill: For pre-drilling holes, especially when creating starting points for your jigsaw blade in electrical openings.
• Table Saw or Circular Saw: Necessary for ripping boards to width or trimming them precisely for corners and edges. A table saw offers superior precision for long, straight cuts.
• Miter Saw: (Optional but highly recommended) A miter saw makes cutting boards to length quick, easy, and precise, especially for repetitive cuts and angled corners.
• Wood Filler: For filling nail holes and minor imperfections in the wood, ensuring a perfectly smooth surface for painting.
• Caulk: To fill gaps where the shiplap meets the ceiling, floor, or other trim. Use a paintable acrylic latex caulk for best results, providing a seamless, professional finish.
• Rags: For cleaning up excess caulk or adhesive, keeping your workspace tidy.
• Sander with Medium Grit Sanding Pads: For smoothing dried wood filler and preparing the surface for an even paint application.
• Outlet Spacers: Crucial for bringing outlets and switches flush with the new shiplap surface, ensuring safety and a proper fit for cover plates.
• Jumbo Outlet/Switch Covers: These larger covers are excellent for gracefully concealing any slightly imperfect cuts around electrical boxes, providing a clean, finished look.
• Flathead Screwdriver: For safely handling electrical components (after turning off power!).
• Paint of your choice: For bathrooms, a satin or semi-gloss finish is highly recommended for its durability, moisture resistance, and ease of cleaning.

The Installation Process: A Detailed Walkthrough

Step 1 – Accurately Measure Your Room’s Perimeter and Calculate Material Needs

Begin by meticulously measuring the entire perimeter of the room where you intend to install the wainscoting. This crucial first step ensures you purchase enough material and plan your cuts efficiently. Once you have this measurement, calculate how many shiplap boards you will require based on the width of your boards. Always factor in extra material for potential waste, miscuts, or future repairs – a good rule of thumb is to add 10-15% to your total. For instance, our powder room had a 22-foot perimeter. We decided on a 4-foot wainscoting height, so we purchased 27 eight-foot boards, which we planned to cut exactly in half. This approach yielded 54 four-foot sections, leaving us with a comfortable buffer for waste and ensuring we didn’t run short mid-project.

Step 2 – Precisely Measure and Cut Shiplap Boards to Length

Using a miter saw, carefully cut your shiplap boards to the desired height. For our project, we opted to cut our 8-foot boards exactly in half to 4 feet. This specific measurement was chosen not only for its simplicity but also because it allowed us to maximize material efficiency and significantly reduce waste, making the project more budget-friendly. Remember to wear appropriate safety gear, including eye protection, when operating power tools. Consistent cuts are key to a uniform look.

Step 3 – Establish the Top Line of Your Shiplap Wainscoting

On your wall, mark the desired height for the top of your wainscoting with a pencil. In our case, this was 4 feet from the floor. Then, using a reliable level (a long level is best for this), extend this mark around the entire room to create a perfectly straight, horizontal line. This line will serve as your unwavering guide for aligning the tops of all your shiplap boards, ensuring a consistent and professional appearance. A crucial tip for smooth installation: strategically place your wainscoting height a couple of inches above any existing outlets or light switches. This foresight will help you avoid awkward, small cuts later and allow for easier installation of the top rail, making your life much simpler.

Step 4 – Verify and Level the Initial Shiplap Board Placement

Before you commit to attaching your first shiplap board, hold it in place against the wall and use your level to double-check its alignment for both plumb (vertical) and level (horizontal) accuracy. This step is paramount; the first board sets the foundation for all subsequent boards. If your first board isn’t perfectly plumb and level, any inaccuracies will compound down the line, resulting in a noticeably crooked installation. Remember, room corners are rarely perfectly true 90-degree angles, so relying solely on the corner for a straight edge can lead to significant problems. Always trust your level over the visual appearance of a corner or wall edge.

Step 5 – Secure Boards with Construction Adhesive and Finish Nails

Once your first board is perfectly leveled, apply a generous S-shaped bead of construction adhesive to the back of the board. Position the board on the wall, aligning its top edge precisely with your pencil line. Firmly press the board into place, ensuring good contact with the adhesive. Then, use your cordless finish nailer to drive a few 1 1/2-inch finish nails strategically into the board to hold it securely while the adhesive cures. The adhesive is especially critical for vertical shiplap installations, as it’s often difficult to align every board with wall studs. Unlike horizontal shiplap, where you can often nail directly into studs for primary support, vertical applications heavily rely on strong adhesive for long-term stability and to prevent warping.

Step 6 – Continue Installation, Consistently Checking for Level and Plumb

Continue this process around the room, attaching each subsequent shiplap board. The tongue and groove system will help guide the planks into place, ensuring consistent spacing between boards. As you work your way across the wall, constantly check each new board with your level to ensure it remains perfectly plumb and aligned with your established pencil line. Even small deviations can become noticeable over time, creating a visually unappealing result, so diligence in checking your level will pay off with a professional-looking finish. Don’t rush this step, as accuracy here is paramount for the overall success of the project.

Step 7 – Custom Trim Boards for Corners and Irregular Spaces

As you approach corners or areas where full boards won’t fit perfectly, you’ll need to trim your shiplap boards to size. Utilize a table saw or circular saw for these cuts. A table saw provides the most accurate and clean rips for precise fits, especially crucial for both inside and outside corners where gaps would be unsightly. Measure carefully, often measuring at multiple points along the board, and make clean, straight cuts to ensure a seamless transition between walls and a professional finish. It’s better to make several small adjustments than one large, irreversible cut.

Step 8 – Precisely Mark Electrical Obstacles on Boards

When you encounter outlets, light switches, or other wall fixtures, you’ll need to make precise cutouts in your shiplap boards. Use a tape measure and pencil to carefully mark the exact dimensions and location of the obstacle on the board that will cover it. Measure the width and height of the electrical box and transfer these measurements to your shiplap board. A helpful trick we often use is to trace the smaller, standard outlet cover directly onto the board. This acts as a convenient template and helps ensure your cut is properly sized. Remember, it’s always better to cut slightly smaller than too large, as you can always trim more off for a perfect fit, but you can’t add wood back on.

Step 9 – Create Starting Points for Jigsaw Cuts

To facilitate clean and accurate jigsaw cuts for your electrical openings, use your power drill to create pilot holes. Drill a hole (large enough to fit your jigsaw blade) at each of the four corners of the traced outlet or switch opening on the board. These holes will provide a convenient starting point for your jigsaw blade, allowing you to easily insert the blade and begin your cut without damaging the surrounding wood or making rough entry points. This technique ensures cleaner, more controlled cuts, especially in delicate areas.

Step 10 – Carefully Cut Out Wall Obstacles with a Jigsaw

With your pilot holes drilled, use your jigsaw to carefully cut along the traced lines, creating the opening for the outlet or switch. Take your time with these cuts to ensure they are as clean and straight as possible. A steady hand and a sharp jigsaw blade will yield the best results. Remember to adjust your grip and angle as needed to navigate the corners smoothly, ensuring you stay within your marked lines. Always double-check the fit before applying adhesive and permanently attaching the board.

Step 11 – Install the Customized Board onto the Wall

Once the cut-out for the electrical box is complete and you’ve verified it fits, apply construction adhesive to the back of the board, just as you did with the others. Carefully place the board on the wall, ensuring the cut-out aligns perfectly with the outlet or switch. Secure it in place with your finish nailer, making sure it’s plumb and level with the surrounding shiplap. Double-check all alignments before moving to the next board. Take extra care with these custom-cut pieces to maintain the overall quality of your wainscoting.

Step 12 – Use Spacers to Make Switches Flush Against Shiplap Boards

With the shiplap now covering your electrical boxes, the outlets and switches will naturally be recessed from the new wall surface. To bring them flush with the new shiplap, you’ll need to install outlet spacers. **IMPORTANT SAFETY NOTE: Before touching any electrical components, ALWAYS turn off the power to the corresponding circuit at your home’s breaker panel. Use a voltage tester to confirm the power is off.** Use a flathead screwdriver to loosen the screws holding the outlet or switch in its box. Slide the plastic spacers behind the outlet/switch until it sits perfectly flush with the shiplap, then carefully retighten the screws. Take all necessary safety precautions when working with electricity to prevent shocks or damage.

Step 13 – Finish with Oversized Outlet and Switch Covers

To achieve a truly polished look and gracefully conceal any minor imperfections in your cuts around electrical boxes, we highly recommend using jumbo or oversized outlet and switch covers. These larger covers offer extended coverage compared to standard plates, ensuring that your previous template cuts (which were often based on smaller covers) are completely hidden. This results in a clean, professional appearance that elevates the overall finish of your wainscoting. This small detail makes a significant difference in achieving a seamless, high-quality look.

Step 14 – Install the Upper Rail for a Finished Edge

Once all your vertical shiplap boards are securely in place and all electrical work is safely completed, it’s time to add the finishing trim. Attach the 1×2-1/2″ Craftsman moulding along the very top edge of your newly installed vertical shiplap wall. This piece serves as the upper rail, providing a crisp, clean line and a sophisticated cap to the wainscoting. Use both construction adhesive and finish nails to secure it firmly, ensuring the top edge is perfectly level across the entire wall. This trim piece not only adds aesthetic appeal but also conceals the raw top edges of your shiplap planks.

Step 15 – Install the Lower Rail (Baseboard)

Next, install the 1×4-1/2″ Craftsman moulding at the bottom of your shiplap boards. This wider piece will act as your new baseboard, providing a sturdy and aesthetically pleasing foundation for your wainscoting. Apply construction adhesive to the back and secure it by nailing directly into the vertical shiplap boards, ensuring a snug fit against the floor and a seamless transition. This completes the primary structural installation of the wainscoting, giving it a complete, built-in appearance.

Step 16 – Fill All Nail Holes with Wood Filler

With all the boards and trim securely in place, the next crucial step is to address any visible nail holes. Using a quality wood filler, meticulously fill every nail hole, ensuring each is slightly overfilled or “proud” of the surface. This allows for sanding without creating depressions. Apply the filler smoothly with a putty knife or your finger. Allow the wood filler to dry completely according to the manufacturer’s instructions, which typically takes a few hours. Proper drying time is essential for a durable, smooth finish.

Step 17 – Seal Gaps with Caulk for a Seamless Look

Once the wood filler is dry, it’s time to caulk. Apply a thin, consistent bead of paintable caulk to all seams and gaps: where the shiplap meets the upper rail, where the lower rail meets the shiplap, where the baseboard meets the floor, and where the shiplap meets the corners of the room. Smooth the caulk immediately with a wet finger or a damp rag for a clean, professional finish. Caulking fills minor gaps, prevents moisture intrusion (especially important in a bathroom!), and creates a seamless, built-in appearance, making your wainscoting look truly custom. Let the caulk dry thoroughly before proceeding to the next step, as indicated on the caulk’s packaging.

Step 18 – Sand Wood Filler Smooth

After the wood filler has completely dried, use your sander with medium-grit sanding pads to smooth out any excess filler, ensuring the surface is perfectly flat and flush with the wood. Be careful not to over-sand and create depressions in the wood. Remember this crucial rule: **never sand caulk.** Sanding caulk will cause it to crack, tear, and lose its elasticity, compromising the smooth finish and sealant properties. Focus your sanding efforts only on the wood-filled areas until they are undetectable to the touch and visually blend seamlessly with the surrounding wood, ready for paint.

Step 19 – The Final Touch: Paint Your Shiplap to Perfection

Finally, it’s time for the most transformative step: painting! For bathroom wainscoting, professional painters overwhelmingly recommend a satin or semi-gloss paint sheen. These finishes are not only more durable and scuff-resistant but also much easier to clean and significantly more resistant to moisture and humidity, which is absolutely essential in a bathroom environment. Specifically, waterborne alkyd paint formulas like Benjamin Moore Advance or Sherwin Williams Pro Classic are excellent choices, offering a hard, furniture-like finish that stands up beautifully to daily wear and the challenges of a humid space.

For our California Casual powder room project, we chose Benjamin Moore Stonington Gray in a satin finish for the elegant vertical shiplap wainscoting. This soft, versatile gray provides a sophisticated and calming contrast to the walls above, which were painted with Benjamin Moore Chantilly Lace in an eggshell finish. The combination creates an airy, serene, and incredibly stylish space that feels much larger, brighter, and more inviting than its previous state. Apply at least two thin coats for optimal coverage and durability, allowing proper drying time between each coat.

It’s truly remarkable how much bigger and brighter this bathroom feels now that the outdated gold paint color has been replaced with this fresh, contemporary palette and the added architectural detail of the vertical shiplap. This project proves that even small spaces can make a huge impact with the right design choices and a little DIY effort. The transformation is not just visual; it significantly enhances the perceived value and comfort of the space.

The final reveal for this charming powder room is just around the corner, so be sure to keep an eye out for the complete transformation, showcasing all the finishing touches. We promise, it’s absolutely perfect and will provide even more inspiration for your next home improvement project!
