Adding a Kitchen Island

Custom Countertops Boise, Idaho

Kitchen islands are beautiful additives to any home that require a bit of thought in advance. A few things to consider include materials, size and area needed, and cost.


When adding a kitchen island, the size and shape of the room determine the size of the island. L-shaped and U-shaped kitchens work best, and square ones should measure at least 12 feet in length and 12 feet in width.

For a kitchen of that size, the island would only have a width of 18 to 21 inches because you need to leave at least 36 inches of aisle space. However, even an addition of that size would still provide plenty of extra countertop space, as long as no one else is trying to wash dishes or cook on the stove while you’re using the island.

Color & Material

A small island does come with two major advantages. You can experiment with bolder colors (Read up on color coordination here) and can splurge on more expensive materials because you’ll need less of them. However, the type of material does matter when it comes to countertop overhang. For example, quartz requires less support than stone.


When considering placement, keep in mind that you’ll need more than 36 inches of space between appliances and the island so that you can open refrigerator, oven and dishwasher doors comfortably. The shape of the island is of equal importance. While square ones seem to make sense for larger kitchens, consider that any countertop larger than 4 feet wide and 4 feet long can provide challenges when trying to keep it clean.

Size & Heights

Don’t forget to consider different stool and chair heights. Typically, kitchen chairs are 18 inches high and were designed to work with 30-inch high dining tables. However, standard countertops measure 36 inches in height. This means that you’ll need adjustable chairs or 24-inch high stools for your typical island. Allow at least 2 feet of space per chair for comfortable seating.


The cost depends on what you want, but you can get a kitchen island for a few hundred dollars at home improvement or big box stores. Custom-built units can run upwards of $6,000.
