Cost will depend on more than the gross dimensions, which is all you’ve stated in your post.

Style, material, finish, features, etc? Including counters, installation?

Check out Ikea, prices easily available online. That’ll give you the lower end of the price range.

Yup…with that as your budget, IKEA gives you the best bang for the buck. They’re well-made, too.

You save a great deal because they’re RTA (ready to assemble), meaning you assemble the cabinets yourself.

I’m a New England-based IKEA kitchen installer, and I can tell you—when it comes to price, IKEA is hard to beat. There’s a lot of talk about IKEA kitchens, mostly from pros who swear by other brands and might have their own reasons for dissing IKEA. The secret is to make sure you’re checking out the IKEA cabinets with plywood boxes, not the ones with particleboard.

If you’ve got a couple of hours to spare, head to your nearest IKEA and see their kitchen setups for yourself. You might be surprised at how good and affordable they really are compared to the competition.

And if you ever decide to hire someone to install your IKEA kitchen, just let me know. We cover NY, NJ, MA, CT, and PA.

For that much cabinets, cheap junk is all you are getting for 20K. Double your budget. As a start.
