Transforming a house into a dream home, especially when preparing it for sale, often involves tackling those long-envisioned projects. One such endeavor recently brought a significant upgrade to my side entry: a custom-built storage bench complemented by sleek upper cabinets. While plans for integrated shoe drawers beneath the bench and stylish doors for the upper cabinets are on the horizon, for now, functional baskets provide immediate organizational solutions. The sheer volume of other home improvement tasks means these finishing touches will have to wait, but the current setup already delivers immense practicality and aesthetic appeal.
This comprehensive guide was proudly sponsored by SPAX, whose exceptional fasteners were integral to the structural integrity and ease of assembly for this project.

Our journey to creating this highly functional mudroom began with an unconventional space. The area was originally a unique nook, formed when we sealed off what is now our formal dining room. This architectural quirk resulted in a distinctive cutout, reminiscent of a secret passage, which ultimately became the perfect foundation for our new mudroom. Strategically located at our home’s side entrance, this spot is ideal for daily routines: effortlessly bringing in groceries, conveniently taking out the trash, and, crucially, serving as a transitional zone when returning from dog walks. No more tracking mud through the main living areas! The need for a dedicated space to manage outdoor gear and easily remove shoes was paramount, leading us to consider various design possibilities. The challenge was immense, with about five distinct ideas, each offering its own blend of style and utility.

Ultimately, the storage bench emerged as the clear winner. Its design brilliantly combined maximum storage capacity with an undeniably appealing aesthetic. For those who follow my projects, it’s no secret that my design philosophy always prioritizes the seamless integration of function and beauty. I firmly believe that every inch of space should serve a purpose, and this project exemplifies that principle. The bench provides ample hidden storage, keeping the entryway clutter-free, while its elegant form enhances the overall ambiance of the space. This dedication to practical elegance guided every decision, ensuring that the mudroom would not only look good but also dramatically improve our home’s organization and flow.

Materials List for Your Mudroom Transformation
Quality materials are the foundation of a lasting build. Here’s a detailed list of what you’ll need to replicate this project, focusing on durability and a clean finish:
- 3/4″ Birch Plywood (for the main bench structure, offering robustness)
- 1/2″ Birch Plywood (for upper cabinets, balancing strength with reduced weight)
- 1×2 Maple Hardwood (for face frames, providing a premium finish and paintable surface)
- SPAX Fasteners:
- 1 3/4″ Hardwood/MDF Screws (ideal for strong, consistent joins)
- 1 1/4″ Cabinet Screws (for general cabinet assembly)
- 2 1/2″ Cabinet Screws (for securing larger components and attaching to wall studs)
- Wood Glue (e.g., Titebond, for strong, long-lasting wood bonds)
- Wood Filler (for concealing nail holes and minor imperfections)
- Primer (to prepare surfaces for a smooth paint finish)
- Paint (your chosen color for the finished look)

Step 1: Constructing the Bench Frame
The first step involves assembling the core structure of your storage bench. I began by applying a generous bead of Titebond wood glue to all mating surfaces, a critical step for creating exceptionally strong joints. After carefully positioning the boards, I utilized clamps and an assembly square to hold the pieces firmly at a perfect 90-degree angle, ensuring a precise and square box. While working on the floor, it can be tricky to apply clamps and a second assembly square on all sides simultaneously. My workaround involves holding the pieces aligned with one hand while quickly shooting in a couple of nails with a nail gun. These temporary nails provide instant stability, allowing me to then drive in the more permanent 1 3/4″ SPAX MDF/hardwood screws with confidence, knowing everything remains perfectly aligned. For now, I only installed two cleats on the top edges, as the final bench top will be custom-fitted once the bench is securely in its designated spot, ensuring an exact, gap-free fit against the wall.

These initial cleats are temporary but essential for the structural integrity of the bench frame during subsequent steps. They will provide a robust anchor point for the final top, which will be cut precisely to fill the entire space once the bench is permanently positioned. This staged approach ensures that any slight wall imperfections or floor irregularities can be accounted for, resulting in a truly custom, built-in look.

Step 2: Building and Leveling the Bench Base
A solid and level base is paramount for any built-in furniture, providing stability and ensuring the entire structure sits correctly. Lacking 2x4s at the moment, I ingeniously constructed a robust base using scrap 3/4″ plywood. The key here is achieving perfect levelness in every direction. I dedicated considerable time to shimming the base until it was absolutely flat and true, a meticulous process that prevents wobbles and ensures a professional finish for the entire bench. Once level, I securely fastened the base to the wall studs using strong 2 1/2″ SPAX cabinet screws. These fasteners are designed for superior holding power, creating a rock-solid foundation that will support years of daily use.

Step 3: Attaching Back Cleats to the Bench
To further secure the bench and provide additional anchoring points, I added 2 1/2″ cleats to the back of the bench frame. This step reinforces the structure and simplifies the process of attaching the bench to the wall. For efficiency and strength, I skipped pre-drilling pocket holes, opting instead for a direct and robust method: I simply drove my SPAX screws in at an angle. This technique, often referred to as “toe-screwing,” creates a surprisingly strong connection without the need for specialized jigs, showcasing the versatility and aggressive thread design of SPAX fasteners. This quick and effective method saved time while ensuring a firm attachment.

Step 4: Positioning and Securing the Bench
With the base meticulously leveled and the back cleats in place, the next step was to carefully lift the assembled bench frame onto its prepared base. This required careful alignment to ensure it sat perfectly square and flush. Once positioned correctly, I secured the bench to the wall studs using more 2 1/2″ cabinet screws, driving them through the back cleats and into the framing. This creates an incredibly stable and integrated unit. During this stage, I encountered a minor setback: I had accidentally cut my initial bench top too short. While a small oversight, it’s a common occurrence in DIY projects! Rather than discarding it, I decided to secure this slightly undersized piece to the cleats anyway. This not only provided an extra layer of structural rigidity to the bench but also created a perfect sub-surface for the final, custom-scribed top, ensuring a super duper sturdy seating surface.

The initial, slightly short top serves as a hidden reinforcement, demonstrating how minor mistakes can often be turned into structural advantages. This underlying support means the final visible top will feel incredibly solid and durable, ready to withstand daily wear and tear in a busy mudroom environment.

Step 5: Installing the Perfect Bench Top
With my plywood reserves depleted, I opted for MDF for the final bench top, a material known for its smooth finish and excellent paintability. The crucial step here was scribing the MDF to the wall. This technique involves tracing the exact contours of the wall onto the material, accounting for any inconsistencies or non-square corners. A jigsaw or belt sander can then be used to precisely cut or shape the board, ensuring a seamless, gap-free fit against the wall—a hallmark of high-quality built-ins. Once perfectly fitted, I applied wood glue to the underlying plywood top and carefully placed the scribed MDF on top. To ensure an incredibly strong bond and prevent any warping, I weighted it down with every heavy object I could find in my workshop, allowing the glue to cure thoroughly for several hours.
Step 6: Adding Face Frame and Decorative Toe Kick
A face frame dramatically elevates the appearance of any cabinet or bench, giving it a finished, furniture-like look while also adding structural rigidity. I meticulously cut, glued, and nailed my 1×2 maple hardwood face frame pieces into place, ensuring tight joints and a smooth surface. Following this, I decided to incorporate a decorative toe kick, a design detail I particularly admired in my kitchen cabinetry. This involves cutting angled or shaped pieces of wood that run along the bottom front of the bench, creating a more refined and intentional look than a simple straight kick plate. These pieces were carefully cut and glued into position, adding an extra layer of custom craftsmanship and visual interest to the bench’s base.

The addition of the face frame not only enhances the visual appeal but also protects the plywood edges, providing a durable surface for painting. The decorative toe kick adds a touch of bespoke charm, tying the mudroom bench into the overall design aesthetic of the home and making it feel like a custom-designed piece rather than a simple utility item.

Step 7: The All-Important Finishing Touches for the Bench
With the structural elements of the bench complete, it was time to prepare it for its final, beautiful finish. This multi-stage process is critical for achieving a professional and durable look. First, I thoroughly sanded all surfaces, starting with a coarser grit and progressing to finer grits, to ensure they were perfectly smooth and free of any imperfections. Next, I meticulously filled all nail holes and any minor gaps with wood filler, allowing it to dry completely before a final light sanding. Once the surface was impeccably smooth, I applied a high-quality primer. Priming is essential for sealing the wood, ensuring better paint adhesion, and creating a uniform base for the topcoat. Finally, after the primer had dried, I applied several coats of my chosen paint, achieving a smooth, even, and durable finish. The transformation was remarkable, yielding an absolutely awesome storage bench, ready to serve its purpose beautifully.

Step 8: Constructing the Lightweight Upper Cabinets
Moving upwards, I began work on the upper cabinets, prioritizing a lighter construction for easier installation and less strain on the wall. For this, I chose 1/2″ birch plywood. These cabinets were designed with simplicity and strength in mind, utilizing basic butt joints. This method involves joining two pieces of wood end-to-end or edge-to-edge. To ensure maximum durability, I secured each joint with a combination of high-quality wood glue and robust 1 3/4″ SPAX screws. The SPAX screws, with their aggressive threading and self-drilling tips, provide exceptional holding power, creating joints that are both strong and resistant to loosening over time, even with regular use of the cabinets.

Step 9: Joining and Securing Multiple Upper Cabinets
When installing multiple upper cabinets side-by-side, it’s essential to join them securely to create a cohesive, built-in appearance. To ensure proper alignment and prevent any bowing or gapping, I strategically placed 1/4″ blocks in between each cabinet unit. These spacers ensure consistent gaps and provide a flat surface for joining. Once aligned, I secured the cabinets to each other using 1 1/4″ cabinet screws. These screws effectively pull the cabinet frames tightly together, creating a single, robust unit that appears as one continuous piece. This method enhances both the structural integrity and the aesthetic appeal of the entire upper storage system.

Step 10: Hanging the Upper Cabinets with Precision
Properly hanging upper cabinets is crucial for safety and stability. There are generally two reliable methods: using a French cleat system or directly securing cleats in the back of the cabinets to wall studs. A French cleat offers excellent adjustability and distributes weight broadly, making installation easier for heavier cabinets. Alternatively, attaching cleats to the cabinet backs, similar to how I secured the bench, and then driving 2 1/2″ to 3″ cabinet screws directly into wall studs provides an equally strong, fixed solution. For this project, I opted for the French cleat method. This involves attaching a beveled strip of wood to the cabinet and a corresponding strip to the wall, allowing the cabinet to hang securely and be easily leveled. This method provides flexibility and ensures the cabinets are perfectly aligned and firmly anchored.

And with that, the main structural elements are in place! While it might seem like the finish line, there are still a few more steps to truly complete the vision for this highly functional mudroom. Each additional detail contributes to the overall aesthetic and utility.

Step 11: Integrating Functional Cubbies
To maximize the storage potential and add an element of practical design, I decided to incorporate small cubbies directly beneath the upper cabinets. These cubbies are perfect for holding smaller items, mail, or decorative accents. To simplify the finishing process and ensure a pristine paint job, I made the strategic decision to paint all the individual cubby components *before* assembly. This foresight prevented what would undoubtedly have been a royal pain of trying to paint into tight corners and crevices after construction. For the cubby unit, I opted for a solid 1/2″ plywood back, providing durability and a clean look. Once assembled and painted, I carefully clamped the cubby cabinet to the underside of the upper cabinets and then securely fastened it to the wall studs using 2 1/2″ SPAX cabinet screws, ensuring it was robustly integrated into the overall structure.
The pre-painting step for the cubbies proved invaluable, saving significant time and effort in the long run. These small organizational compartments significantly enhance the functionality of the mudroom, providing designated spots for various items and contributing to a tidy and efficient entryway.
Step 12: Addressing the Wall for a Seamless Look
The next critical step involved tackling the wall itself, which presented a unique challenge due to a previously patched door opening. My primary goal was to avoid any further extensive drywall patching or skim coating, a task I was keen to bypass. The perfect solution came in the form of decorative wall planking. This not only concealed the door patch flawlessly but also added character and texture to the mudroom, transforming a functional space into a visually appealing area. The planks provided a clean, consistent surface that beautifully complemented the newly installed bench and cabinets, creating a cohesive and polished aesthetic.

Step 13 (Optional): Creating a Decorative Cross Header
This particular step addresses a unique architectural situation in my home, primarily applicable if you have an unusual or “funky” door setup. To provide a clean termination point for the wall planking and to defer decisions about the adjacent areas, I needed to create a decorative cross header. This header needed to protrude slightly beyond the planks and extend all the way up to the ceiling, effectively framing the mudroom entrance and allowing the planking to end neatly. This design choice gave me the flexibility to decide later what I might do on the other side of the doors—perhaps extending the wall or adding further trim. In DIY, there’s always something else to consider down the road! Once the header was in place, I completed the installation of the remaining wall planks, creating a truly integrated and thoughtfully designed space.
The custom cross header is a testament to adapting design solutions to unique home layouts, ensuring a professional finish even in challenging spaces. It provides a visual anchor and allows for future modifications without impacting the integrity of the mudroom design.

Step 14: Extending the Face Frame for Crown Molding
To achieve a truly built-in, custom look that seamlessly integrates with the ceiling, I wanted the face frame to extend all the way up. This provides a solid backing for the crown molding, ensuring a clean and professional finish where the cabinetry meets the ceiling. To support this extended face frame, I added strategically placed wooden blocks along the top edge of the upper cabinets and wall, providing crucial attachment points. Following this, I carefully measured, cut, glued, and nailed each piece of the face frame extension into place, working meticulously piece by piece. This detailed approach ensures tight, precise joints and a perfectly straight line, critical for the flawless installation of crown molding in the next stage.
The extended face frame creates a robust and continuous surface, essential for the elegant transition from the cabinet structure to the decorative crown molding. This attention to detail significantly enhances the bespoke feel of the mudroom built-ins, making them appear as if they were always part of the home’s architecture.
Step 15: Final Painting, Crown Molding, and Hooks
With all the structural and decorative elements now firmly in place, it was time for the penultimate step: a comprehensive paint job. I meticulously painted all surfaces of the built-ins and wall planking, ensuring even coverage and a smooth, professional finish. My strategy for the crown molding was to paint it separately before installation. This clever approach minimizes touch-ups; once the crown molding is installed, only the small nail holes need to be filled, sanded, and painted, saving considerable time and effort. Now, all that remains are the final touches: installing the freshly painted crown molding to bridge the gap between the cabinets and ceiling, and adding the functional hooks for coats and bags. While the project is “mostly finished,” and I absolutely adore the results, there’s always the possibility of future enhancements as new ideas spark!
Even in its “mostly finished” state, I am absolutely thrilled with the transformation. This mudroom now serves as a highly efficient and beautiful entryway, solving our storage dilemmas and enhancing the daily flow of our home. The functionality of the bench and cabinets, combined with the aesthetic appeal, makes this project a true success. While I envision adding custom drawers and doors in the future to match potential kitchen cabinet styles, for now, the open storage with baskets and the elegant simplicity of the upper cabinets provide exactly what we need. This built-in solution has brought immense joy and order to a previously underutilized space, proving that thoughtful design and dedicated DIY effort can create truly impactful changes within a home. It’s a testament to how even “mostly finished” can still be absolutely perfect.
