How to Build an Appliance Garage: DIY Installation Guide

Building an appliance garage transforms cluttered countertops into organized, functional workspace. Whether you're adding a corner appliance garage during a kitchen renovation or retrofitting your existing space, this DIY installation guide walks you through the entire process — from planning and measuring to installing tambour doors.

With basic carpentry skills, the right tambour door kit, and a weekend's worth of work, you can create a professional-looking appliance garage that rivals custom installations at a fraction of the cost.

Planning Your DIY Appliance Garage

Before you purchase materials or pick up tools, careful planning ensures your appliance garage functions properly and looks built-in rather than added on.

Assessing Your Space

Start by deciding where your appliance garage will live. Corner installations are popular because they utilize otherwise awkward counter space, while straight cabinet garages work well near food prep areas or beside refrigerators.

For Corner Appliance Garages: Measure the available space on both wall faces. Most corner garages use 18-24 inches on each side, creating a garage that's roughly 24-30 inches wide at the opening. Check that you have adequate depth (typically 18-24 inches from the back corner to the counter edge) to accommodate your appliances plus the tambour door track.

For Straight Cabinet Installations: Measure the linear run where you want the garage installed. Consider what's above (upper cabinets or open wall) and to the sides (adjacent cabinets or appliances). Your appliance garage should align with these elements for a seamless look.

Critical Measurements:

• Width of opening needed for your appliances
• Depth from back wall to counter front
• Height from counter to upper cabinet bottom (or ceiling)
• Location of existing electrical outlets

Measure your specific appliances before finalizing dimensions. A coffee maker might be 14 inches deep, but you'll need to add:

• 2-3 inches for the tambour track and door thickness
• 1-2 inches of clearance behind appliances for outlets and cord management

Similarly, standard appliance garages measure 16-20 inches tall, but add an inch to your tallest appliance to make sure everything will fit. A stand mixer with the bowl and attachment can reach 17 inches, while some coffee makers approach 15 inches. 

Choosing Your Approach: Kits vs. Custom Build

Most DIYers find success using appliance garage kits, but you can also use a tambour door sheet paired with either existing cabinets or simple cabinet boxes. When working with a full appliance garage kit, you get:

• Pre-assembled door with flexible wood panels ready to install
• Side panels in a variety of materials and finishes
• Included track hardware and screws
• Clear instructions and proper sizing
• Professional results without custom woodworking

You can also install just a tambour door sheet with your existing cabinets. This is much simpler than building a custom appliance garage from scratch — you're just creating the housing for a pre-made door system. But it does require carpentry skills to cut panels to the right size, as well as trimming out your garage to make sure it’s cohesive with your existing cabinetry.

You could theoretically build both the cabinet box and tambour door system from scratch, but this requires advanced woodworking skills, specialty tools (table saw, router, dado blade, etc.), precise measurements for track placement, and custom fabrication of the flexible tambour door. For most homeowners, the time, tools, and expertise needed make this approach impractical compared to using a quality tambour door kit that's designed to work right out of the box.

This guide focuses on the kit-based approach, which delivers professional results without the complexity of custom fabrication.

Choosing Your Appliance Garage Kit

Selecting the right kit is the most important decision you'll make. All of our appliance garage kits come as a complete unit, so getting the correct size is important to ensure everything works as expected.

Available Sizes

Complete appliance garage kits typically come in standard widths:

• 18 inches wide: single appliance (coffee maker or toaster)
• 24 inches wide: two small appliances or one large appliance
• 30 inches wide: multiple appliances

They also come in either a straight or corner configuration. Make sure you order the correct type for your kitchen, as corner and straight kits are not interchangeable.

Wood Species and Finish Options

Complete kits come in popular wood species such as red oak, maple, cherry, and birch. They also come in either finished or unfinished options. For best results matching existing cabinets, most DIYers choose finished kits that match their existing kitchen cabinets. However, if you have painted cabinets, you may need to paint your kit to match.

What You'll Need: Materials and Tools

Once you’ve chosen your appliance garage kit, you’ll need to gather a few more things. Having the right tools ensures proper mounting and a finished product that looks built-in.

Our appliance garage kits are complete, pre-fabricated units that include:

• Tambour door mounted to a solid wood face frame
• Prefinished side panels in a variety of materials and finishes
• Tracks for smooth door operation
• All necessary mounting hardware and brackets
• Doweled joints for easy, strong assembly
• Spring-assisted roll system for smooth opening

You might also need:

• Shims for leveling and alignment
• Wood glue (optional, for reinforcing joints)
• Finishing materials (if kit is unfinished):
• Stain or paint to match your cabinets
• Clear coat or polyurethane
• Sandpaper (120 and 220 grit)
• Paintbrushes
• Caulk in a color that matches your cabinets

• Drill with bits or screwdriver
• Level
• Tape measure

• Safety glasses
• Dust mask (if sanding or finishing)
• Work gloves

Preparing for Installation

Before you start installing, proper preparation ensures smooth progress. To start, your appliance garage mounts to wall studs, not just drywall.

• Use a stud finder to locate studs in your installation area
• Mark stud locations with painter's tape or a pencil
• You need at least 2-3 studs within your mounting area for secure installation

Finishing the Kit (If Unfinished)

If your kit is unfinished, it’s easier if you add finish before assembly. You’re more likely to get a smooth and even finish this way, rather than trying to work around your other cabinets and countertops. 

Sanding:

• Lightly sand all surfaces with 120-grit sandpaper
• Follow with 220-grit for a smooth finish
• Sand in the direction of the wood grain
• Remove all dust with a tack cloth

Staining (if matching stained cabinets):

• Apply wood conditioner to prevent blotchy appearance (especially on oak or pine)
• Apply stain with a cloth, following manufacturer directions
• Wipe excess and allow to dry completely
• Apply second coat if needed for color depth
• Let dry 24 hours before clear coat

Painting (if matching painted cabinets):

• Apply primer suitable for wood
• Sand lightly after primer dries
• Apply 2-3 coats of cabinet paint, allowing drying time between coats
• Let final coat cure for 24-48 hours before installation

Clear Coat:

• Apply 2-3 coats of polyurethane or clear coat
• Sand lightly with 320-grit between coats
• Final coat should cure 48-72 hours before installation

Custom Service Hardware carries a full line of stains and polyurethane for your finishing needs, so you can buy them at the same time as your appliance garage.

Kit Assembly

Most kits require minimal assembly as the tambour door is already mounted to the face frame, so you're just joining the side panels. It’s important to follow the directions included with your individual kit, but we’ll walk through a common assembly process so you understand what’s involved.

Step 1: Join Side Panels to Face Frame

• Most kits use doweled joints that simply press together
• Apply wood glue to dowel holes in the face frame
• Align side panels with dowel holes
• Press firmly together until joints seat completely
• Wipe away any excess glue immediately

Step 2: Verify Unit is Square

• Use a carpenter's square to check corners are 90 degrees
• Check that the unit sits flat on your work surface
• Make any adjustments before glue sets

Step 3: Allow Glue to Cure

• Let assembled unit sit for at least 1 hour before handling
• Full cure typically takes 24 hours
• Don't stress joints during cure time

Step 4: Verify Door Operates Smoothly

• Roll the door up and down several times
• It should glide without binding or sticking
• Spring-assisted opening should feel smooth
• If door sticks, check that tracks are clean and properly seated

Installing the Appliance Garage

With your kit assembled and finished, you're ready for installation.

Step 1: Positioning the Unit 

• Lift the assembled garage and set it into position
• Check level front-to-back and side-to-side
• Adjust with shims as needed

Step 2: Verify Alignment Before Driving Any Screws

• Check that unit is level in all directions
• Front edge aligns with adjacent cabinets (if any)
• Positioned at correct height relative to upper cabinets
• All gaps are even and consistent

Step 3: Mount to Walls

• Drill pilot holes if needed
• Holes should align with wall studs you marked earlier

• Use 3-inch screws through panels into wall studs
• Start with top corner screws to hold unit in place
• Tighten gradually, checking that unit doesn't shift
• Don't over-tighten! You can crack or split panels

Step 4: Final Check

• Verify unit is still level after all screws are tight
• Test tambour door operation again — it should roll smoothly
• Check for any wobble or movement (shouldn't be any)

Corner Installation Specifics

Corner appliance garages require extra attention:

• Both walls must have stud locations for mounting
• Both sides must be perfectly level for the curved track to work
• Shim behind unit if walls aren't perfectly square

Finishing Touches

It might be tempting to call it a day once your appliance garage is installed, but the details are what make the difference between "DIY project" and "professional installation." 

Apply Caulking:

• Use caulk matching your cabinet color (or clear)
• Apply a thin bead of caulk where the unit meets the wall, countertop, and adjacent cabinets
• Apply with steady pressure, then smooth with a wet finger immediately
• Wipe excess with a damp cloth before it dries
• Let cure per manufacturer instructions

Install outlets:

• Hire a licensed electrician (recommended for safety and code compliance)
• Outlets typically install 4-6 inches above counter
• Cost is typically $150-$300 for professional installation

Add Lighting:

• Battery-powered LED puck lights mount to the top
• Motion-activated options turn on when door opens
• Creates a premium feel and improves visibility

Troubleshooting Common Installation Issues

Even with complete kits, you may encounter issues. Luckily, most are easy to resolve and don’t take additional tools or materials.

Issue	Possible Causes	Solutions
Tambour Door Sticks or Binds	Unit not level (tracks must be level for smooth operation) Debris in tracks Side panels squeezed too tightly against door during assembly	Loosen mounting screws slightly and re-level unit Remove door and clean tracks thoroughly Check that side panels haven't shifted
Door Won't Stay Closed/Open	Spring mechanism not engaged properly Tracks installed at wrong angle Unit not mounted level	Check spring mechanism per kit instructions Verify tracks are level  Remount unit ensuring perfect level
Gaps Between Unit and Cabinets	Wall not plumb Adjacent cabinets not perfectly aligned Unit mounted at slight angle	Use shims behind unit to compensate for wall irregularities Fill small gaps with caulk (gaps under 1/4-inch) For larger gaps, consider adding decorative trim
Unit Feels Wobbly	Not enough mounting screws into studs Screws too short or not hitting studs Panels not properly secured	Add more mounting screws at stud locations Use longer screws (3-inch minimum) Verify all screws actually hit studs (not just drywall)

Frequently Asked Questions

Can I install an appliance garage kit myself?

Yes, complete appliance garage kits are designed for DIY installation. With basic tools (drill, level, screwdriver), most homeowners can successfully install a kit. The key is choosing the right size kit, finishing it to match your cabinets, and ensuring it's mounted level and securely to wall studs.

Do I need to build a cabinet box for an appliance garage kit?

Complete appliance garage kits include the tambour door, face frame, side panels, and all necessary hardware. You're assembling and mounting a pre-fabricated unit to your wall, not building a cabinet from scratch. This makes installation much faster and easier than custom construction.

What's the difference between corner and straight appliance garage kits?

Corner kits typically offer more storage space due to the larger corner area, allowing you to store more appliances. Straight kits follow the linear run of your counter, but are often easier to blend in seamlessly with your existing cabinets.  

Should I hire an electrician to add outlets to my appliance garage?

Yes, we strongly recommend hiring a licensed electrician to install any electrical outlets. This ensures proper code compliance, safe installation, and correct GFCI requirements. Professional electrical installation is fairly affordable and provides peace of mind.

How do I match the kit finish to my existing cabinets?

You can order an unfinished kit and apply the same stain or paint used on your existing cabinets, or take one of your cabinet doors to a paint store to get an exact color match. Apply stain or paint to the kit before installation, following the same process used on your cabinets (primer, paint/stain, clear coat) to ensure a seamless match.
