Kitchen remodels can be expensive, so the last thing you want to do is make mistakes that must be fixed later. And because you likely use your kitchen multiple times per day, you want to ensure that the room is as functional and beautiful as possible. So if you’re considering a kitchen remodel, watch out for these seven common mistakes.

Trends that quickly go out of fashion. Currently, gray is a popular choice, and it’s a neutral color that will likely still seem fashionable in many years. But if you’re considering a bright, trendy color, think twice. Use trendy colors in areas that are easy to switch out, such as dishes, placemats, towels, and so on. Leave them off of permanent elements like cabinets.

Gigantic islands. Kitchen islands are a terrific way to create extra storage and prep space. But they can also become a traffic obstacle. Keep your island reasonably-sized, so that walking around it doesn’t become a huge pain.

Not enough walking space. On the topic of traffic obstacles, make sure you leave 42 to 48 inches of walking space between cabinets and an island, or other areas in the kitchen where you need to walk.

Faulty door clearance. Kitchens are full of doors, from the cabinets to appliances. Make sure all those doors have room to open fully, and that they open in a convenient direction. If you’re purchasing a new refrigerator, consider one with doors that can be reversed. That way, if you discover a problem, it can be easily remedied.

Wasted space. Kitchens must be functional as well as beautiful. So consider how you will use each area of the room, and plan for the appropriate storage in those areas. You want to avoid walking back and forth all over the kitchen while preparing a meal.

Not enough storage. No one ever complains that their kitchen has too much storage. As you finalize your design plans, go for extra storage options whenever possible.

Changing your mind during the renovation. Making changes during the renovation will only result in a larger expense and more hassle. Finalize your design before the your contractor begins work.
