Kitchen Island Costs Based on Countertop Materials

Many factors affect the cost of kitchen islands, but the significant one is the countertop material used. Some islands already come with a built-in countertop, specifically stock islands.

If you prefer a custom or semi-custom one, you have to buy the countertop separately after your island installation. You also need to prepare a cooktop or sink if you need these features.

Different countertop materials, including stainless steel, laminate, tile, stone, and others, are available.

Butcher Block

A semi-custom butcher block or wood kitchen island can cost you an average of USD 3,700 to $9,900, while custom islands with additional features range between $7,700 and $14,000. Every square foot of wood countertops costs $30 to $280.

A new kitchen island made from this material can be made in different wood species and come in many styles. Each one of them has extra longevity, appearance, and labor costs.

Stock kitchen islands will most likely come with an integrated butcher block top at no additional cost.
