Remodeling a kitchen requires a lot of effort (and cash). Avoid making costly mistakes with these expert tips for every aspect of your design – from islands to floor plans and everything in between.

1. PLAN THE SPACE.

Even in big kitchens, you’ll want to create a compact step-saving work core. You don’t want to walk a mile to make a meal, or even worse, generate dead space within the room. Pick areas that will work hard during meal prep, dining and family time. A breakfast nook, for example, is the perfect way to add style without sacrificing too many steps.

2. MEASURE!

Kitchen aisles need to be wide enough to accommodate all that goes on in a kitchen. Clearance helps multiple cooks navigate the space and maneuver around each other. When designing your new kitchen, make sure all aisles – such as those between islands, walls and appliances – are between 42 and 48 inches wide. Also consider offsetting the placement of key features, such as sinks and the range, so two cooks don’t bump into one another.

3. ENSURE IT’S FUNCTIONAL.

When planning the space, consider the size and direction of doors, appliances and cabinets. Fridges often need wide clearance, as do ovens. Take a walk through the space and plan door openings to ensure that you don’t create a cramped kitchen.

4. BUY AN ISLAND (OR TWO).

In a big room, two islands are often better than one. It’s a mistake to supersize an island, because anything longer than 10 feet is hard to walk around. Also, if an island is more than 4 feet deep, it’s hard to reach the middle. Overstuffing an island with dinnerware, baskets and other items creates a similar problem. Make sure no island storage extends beyond the rim of the countertop.

5. PUT IN A PENINSULA.

In a small kitchen, a small peninsula often works better than an island. Keep your space in mind every step of the way to ensure the best remodel possible. Don’t overwhelm a small space; there are options available for a variety of sizes and layouts.

6. PLAN AHEAD.

Get all your ducks in a row before you begin your kitchen remodel. Delays and changes midstream can send costs soaring. Do your homework and consider each choice ahead of time. Be sure to check that everything has arrived before the contractor is ready to install.

7. CHOOSE STORAGE WISELY.

A good design includes storage solutions that match items used in specific areas. Between open storage, cabinets, shelves and more, there are hundreds of options available. Consider the goal of the remodel: If you are going for a sleek look and choose glass cabinet doors, keep the cabinet contents streamlined and unfussy, as well.

8. INCLUDE SPACE FOR ENTERTAINING.

Whatever a kitchen’s size, expect friends and family to congregate there. People are drawn to other people, and your guests don’t want to be hanging out in the living room while you’re preparing dinner. Plan for interactive space in your new kitchen – whether that’s a corner nook, island with seating or a banquette.

9. BRING HOME SAMPLES.

Materials can look a lot different in a showroom than they do in your actual space. Don’t commit to any major design element – such as flooring or countertops – until you’ve brought the samples home to look at in the space you’re remodeling. You may also want to look at samples under lighting similar to what will be used in the new space.
