Wooden Kitchen Islands: When They Pay Off and How Much Space They Need

A kitchen island is a free-standing cabinet in the middle of the space that adds extra worktop, a quick seating spot, and sometimes separates the sink or the range hood from the wall. The first question most clients ask is whether their kitchen even has room for one.

The minimum clearance you need

For an island to actually work rather than get in the way, it needs at least 90 to 120 centimeters of clearance all around it — enough for two people to open the surrounding cabinets at the same time and pass each other. That means a kitchen narrower than roughly 3.6 meters usually has no room for a standard island; at that width, a small mobile cart or half-island is the more realistic choice.

• Simple island (cabinet and worktop only): at least 120 centimeters long
• Island with a sink or cooktop: at least 150 centimeters, to allow for plumbing and ventilation
• Island with bar seating: budget roughly 60 extra centimeters of overhang per stool

An island is more than a worktop

Many clients ask for just a plain cabinet surface, but an island can take on other jobs too: drawers for dishware on both sides, a hidden trash pull-out in one of the cabinets, or even a built-in microwave in the body. If a cooktop or sink goes on the island, that needs coordinating with the electrician and plumber from the start, since the water and ventilation lines under the kitchen floor have to go in before the tiling.

How the island surface differs from wall cabinets

Because an island is visible from every side, its edges usually need full finishing — not just the front face, but the sides too have to match the rest of the cabinets in color and veneer. For the worktop itself, since it's where cutting happens and hot dishes get set down, the same wood choice guide for kitchen cabinets applies, with extra attention to scratch and moisture resistance.

When an island isn't the right call

If the kitchen is small, or the main traffic path runs straight through its middle, a fixed island gets in the way more than it helps. In those cases, a mobile cabinet on casters, or adding more wall cabinets and using open shelving for extra storage, usually works out better.
