Kitchen design mistakes to avoid

Designing a kitchen is one of the most exciting home improvement projects you can take on, but it’s also one of the easiest to get wrong.

The kitchen is a high-function space, and even small design errors can create issues that last for a long time (and can be expensive).

Whether you’re planning a full renovation or making a few upgrades, understanding these common kitchen design mistakes will help you create a space that is practical and stylish.

Ignoring the Kitchen Work Triangle

The work triangle is fast to the distance between the sink, stove, and refrigerator. Your three main work zones. If they’re too far apart or too close, the kitchen becomes inefficient.

A poorly planned triangle leads to awkward movement and difficulty when preparing meals.

To prevent this, keep each leg of the triangle between four and 9 feet away from one another to ensure that the kitchen flows smoothly.

Not Planning Enough Counter Space

Of all kitchen complaints, lack of counter space is one of the most common.

From meal preparation to setting down groceries, counters are important.

Cramped counters create clutter and make cooking stressful, so prioritise counter length during the design process.

If you have enough space, add a kitchen island or even more surface area. Even a small overhang or extending the countertop to a window can make a big difference.

Choosing Style Over Function

Trendy materials and finishes look great online, but not all of them withstand daily use.

It’s important that you consider your maintenance and long-term use so that your kitchen continues to be practical.

For example, high gloss cabinets can show fingerprints and soft porous countertops can stain easily.

If you cook frequently, choose materials that are strong, stain resistant and easy to clean.

Poor Storage Planning

A kitchen can look gorgeous but if it lacks day-to-day storage, it can quickly become chaotic. Many homeowners underestimate how much storage they truly need.

To avoid this, incorporate small storage solutions such as deep drawers for pots and pans, pull-out pantry shelves, and vertical shelf dividers.

Think about exactly what you need to store and design cabinetry around those items.

Not Upgrading The Hardware

Speaking of cabinets, one way to make your kitchen look outdated is to not upgrade your hardware.

Simply switching out cabinet door knobs and door handles can make a huge difference to the look and feel of your kitchen.

Choosing the Wrong Appliance Sizes

Oversized appliances look luxurious but aren’t always practical, especially if you have a smaller kitchen.

For example, a giant refrigerator can crowd walkways or make cabinets in accessible.

It’s important to measure carefully, not just length, but depth, door swing, and clearance requirements.

Choose appliances that suit your space and your cooking habits, not what's trending.
