10 IKEA Kitchen Design Mistakes to Avoid

Learn From Other People's Mistakes

The IKEA Kitchen Planner is a powerful tool, and IKEA's SEKTION system offers incredible flexibility. But that flexibility also means there are many ways to get things wrong. After installing hundreds of IKEA kitchens across Pennsylvania, Delaware, Maryland, and Washington DC, we have compiled the most common mistakes we see and how to avoid them.

Catching these errors at the design stage is straightforward. Discovering them on installation day is expensive and frustrating. Here are the top 10 mistakes to watch out for.

1. Inaccurate Measurements

This is the single most common and most consequential mistake. Every other decision in your kitchen design depends on accurate measurements.

What Goes Wrong

• Measuring to the outer edge of drywall versus the stud location
• Forgetting to account for out-of-square walls and uneven floors
• Missing the locations of plumbing pipes, electrical outlets, and gas lines behind walls
• Not measuring ceiling height at multiple points, since older homes often have uneven ceilings

How to Avoid It

• Measure each wall at least three times at floor level, counter height, and upper cabinet height
• Measure ceiling height in multiple locations across the kitchen
• Use a level to check if walls are plumb and floors are level
• Map every pipe, vent, outlet, and switch with measurements from at least two reference points
• Consider hiring a professional to measure. Our free in-home measurement service catches issues that most homeowners miss.

2. Ignoring Filler Pieces

IKEA cabinets come in fixed widths: 12, 15, 18, 21, 24, 30, and 36 inches. Your walls almost certainly will not be an exact multiple of these sizes. That is where filler strips come in. They bridge the gap between the last cabinet and the wall.

What Goes Wrong

• Designing a layout that leaves awkward gaps between cabinets and walls
• Forgetting to order filler pieces entirely
• Using fillers that are too narrow, under 2 inches, which look odd and are hard to install cleanly

How to Avoid It

• Always plan for filler strips of at least 2 to 3 inches at wall transitions
• Place fillers in corners or against walls where they are least visible
• Order extra filler material. It is inexpensive and far better to have it than need it.

3. Forgetting About Toe Kicks

Toe kicks are the recessed panels at the base of your cabinets. IKEA's SEKTION base cabinets sit on adjustable legs, and the toe kick covers snap onto those legs. They are a separate purchase, and they are easy to forget when building your order.

What Goes Wrong

• Not ordering toe kick boards and cover plates at all
• Not ordering enough toe kick material for islands, which need toe kicks on all exposed sides
• Forgetting the toe kick for filler areas and inside corners

How to Avoid It

• Measure the total linear footage of toe kick needed for every cabinet run, including islands and peninsulas
• Order 10 to 15 percent extra since cuts and corners create waste
• Do not forget the corner connector pieces that allow toe kicks to turn 90 degrees cleanly

4. Poor Appliance Clearances

IKEA cabinets are designed to work with specific appliance dimensions, but not all appliances are the same size. Even a quarter-inch difference can prevent a dishwasher from fitting or a refrigerator door from opening properly.

What Goes Wrong

• Designing around standard appliance sizes without checking your actual appliance specifications
• Forgetting that a refrigerator door needs clearance to open past the adjacent cabinet or wall
• Placing an oven or range too close to a corner, making it impossible to fully open the oven door
• Not leaving enough space for the dishwasher to open when the oven door is also open

How to Avoid It

• Download the specification sheets for every appliance you plan to install before starting your design
• Design with the actual dimensions, not assumed standard sizes
• Check door swing clearances. Refrigerators, ovens, and dishwashers all need room to open fully.
• Leave at least 3 inches of clearance between an oven or range and an adjacent wall or tall cabinet for heat dissipation

5. Skipping Cover Panels

Cover panels, also called end panels or skin panels, are the decorative panels that cover the exposed sides of cabinets. Any cabinet side that is visible at the end of a run, on an island, or next to a refrigerator needs a cover panel to look finished.

What Goes Wrong

• Not ordering cover panels for exposed cabinet sides
• Ordering the wrong size cover panel, since base cabinet panels are different from wall cabinet panels
• Forgetting that islands need cover panels on all non-adjacent sides

How to Avoid It

• Walk through your design mentally and identify every exposed cabinet side
• Order cover panels that match your door style and color
• For islands, you will typically need cover panels on the back and both ends
• Consider using a cover panel on the side of your refrigerator enclosure for a cleaner look than raw cabinet material

6. Wrong Door Hinge Direction

Every cabinet door opens either left or right. In the IKEA planner, it is easy to place doors without thinking about which direction they should swing. Incorrect hinge placement makes your kitchen frustrating to use every single day.

What Goes Wrong

• Upper cabinet doors that open toward a wall instead of toward the center of the work area
• Paired doors that open in the wrong direction, banging into each other when both are open
• Doors that block access to adjacent cabinets or drawers when open

How to Avoid It

• Stand in front of each cabinet in your design and imagine reaching for its contents
• Doors should generally open away from the nearest wall and toward the main work area
• Paired doors should open outward, meaning the left door hinges on the left and the right door hinges on the right
• Check that no open door blocks another cabinet or drawer from opening simultaneously

7. Insufficient Lighting

Kitchen lighting is often an afterthought, but it has an enormous impact on how your kitchen looks and functions. IKEA offers integrated lighting solutions, but they need to be planned into the design from the start because they affect electrical rough-in.

What Goes Wrong

• Relying on a single overhead light fixture for the entire kitchen
• Not planning for under-cabinet lighting, resulting in shadows on your countertop work surfaces
• Forgetting to include interior cabinet lighting for tall pantry or glass-door cabinets
• Not planning electrical outlets or hardwire connections for lighting before cabinets are installed

How to Avoid It

• Plan for three layers of lighting: ambient (overhead), task (under-cabinet), and accent (in-cabinet or decorative)
• IKEA's OMLOPP and IRSTA LED strips work well for under-cabinet task lighting
• Have your electrician install outlets or hardwire connections for under-cabinet lights before cabinets go up
• Consider in-drawer lighting for deep drawers. It is a small luxury that makes a big difference in daily use.

8. Ignoring the Work Triangle

The kitchen work triangle, the relationship between the sink, stove, and refrigerator, is a fundamental kitchen design principle. These three points should form an efficient triangle that minimizes steps during cooking.

What Goes Wrong

• Placing the sink and stove too far apart, requiring excessive walking during meal prep
• Putting the refrigerator in a location that disrupts the flow between sink and stove
• Creating a triangle path that crosses through a high-traffic walkway or island seating area
• Making the triangle too small, resulting in a cramped, uncomfortable cooking experience

How to Avoid It

• Each side of the work triangle should be between 4 and 9 feet
• The total perimeter of the triangle should be between 13 and 26 feet
• No leg of the triangle should cross through an island or peninsula
• If you have a two-cook kitchen, consider two overlapping work zones instead of one triangle

9. Choosing Trendy Over Timeless

IKEA offers a wide range of door styles, from ultra-modern high-gloss to traditional shaker profiles. It is tempting to choose the trendiest look, but kitchens are a long-term investment that you will live with for 10 to 20 years.

What Goes Wrong

• Choosing bold, saturated cabinet colors that feel dated within a few years
• Selecting ultra-trendy hardware that does not age well
• Mixing too many different door styles or colors in one kitchen, creating visual chaos
• Forgetting that IKEA discontinues styles periodically, meaning future replacement doors or panels may not be available in your chosen style

How to Avoid It

• Neutral cabinet colors including white, off-white, gray, and natural wood tones have the longest staying power
• Add personality through easily changeable elements: backsplash tile, hardware, accessories, and wall paint
• Limit your design to two door styles maximum, one for base and wall cabinets and optionally a second for an island or accent area
• If you love a bold color, use it on the island only and keep the perimeter cabinets neutral
• Consider IKEA's BODBYN for a classic look or AXSTAD for modern minimalism. Both are timeless choices.

10. Not Planning for Plumbing and Electrical

Your IKEA kitchen design needs to account for where water supply lines, drain pipes, electrical outlets, and gas lines are located, or where they need to be moved to. This is often the most expensive oversight.

What Goes Wrong

• Designing a sink cabinet location without checking if the drain pipe can reach that position
• Planning for an island sink without budgeting for the significant plumbing work to run supply and drain lines under the floor
• Not including enough electrical outlets. Code typically requires outlets every 4 feet along countertops and dedicated circuits for major appliances.
• Forgetting about the range hood venting route. Does it vent through the wall, through the ceiling, or recirculate?

How to Avoid It

• Document all existing plumbing and electrical locations before starting your design
• Consult with a licensed plumber and electrician during the design phase, not after ordering your kitchen
• Budget for plumbing and electrical work separately. These are often the most expensive parts of a kitchen renovation beyond the cabinets themselves.
• Plan outlet locations to comply with local building codes. DC, Maryland, Pennsylvania, and Delaware all follow the National Electrical Code with local amendments.
• Decide on your ventilation strategy early. Ducted ventilation requires planning the duct route before cabinets are installed.
