How to Build a Kitchen Island with Sink and Dishwasher

If there is a magical place in a home, it has to be the kitchen island. I mean, what other place combines without effort aesthetics, functionality, and the possibility of developing, growing, and caring for all kinds of relationships? Only in kitchen islands, ladies and gentlemen. So let’s grab our tools and build this wonderful place. Here’s what you need to do and build a kitchen island with a sink and dishwasher:

Measure Your Space

It might seem obvious, but every kitchen is its own world, with its own dimensions. So the first step in every remodeling project is to take out your measuring tape and get the real numbers you will be working with. After all, the objective of building a kitchen island is to make your kitchen more comfortable, functional, and good-looking. But build a kitchen island that is too big, and you will hate your kitchen in two days, feeling trapped with no space. Build it too small, and it will be more of an obstacle in your way than a functional space.

Set Your Budget

I feel it is so important to put this before we talk of the actual process of how to build a kitchen island. The materials and design you will be able to work with will be highly influenced by the amount of money you can spend on it. And if you will be buying a new sink and/or dishwasher to go with your kitchen island, then you should have this too in mind.


Okay. You measured your space and set your budget for this project. It’s time. Here’s a list of the things you will need to buy and build your kitchen island:

  • Base cabinets with back panels
  • Wooden board or fiberboard (to add extra support, especially for the countertop where the sitting area will be located)
  • Countertop (material of your preference)
  • Industrial adhesive
  • Screws
  • Saw
  • Power drill
  • Paint
  • Level
  • Tape
  • Pencil
  • Sanding supplies

Prepare Your Working Area

There is probably going to be a lot of dirt and spills while you build your island kitchen. So prepare your floor to avoid any damage. Needless to say, wear appropriate clothes for the task.

Cabinets Assemble!

We are not going to save the world, but we are for sure going to upgrade your kitchen. Follow the manufacturer’s instructions for assembling the cabinets, but don’t place the doors yet, or you might have trouble with the next step. Identify every part first by checking them with the instructions, and make sure that you have all the screws and nails you need.

Assemble the toe-kick, too, but don’t attach the cabinets to it just yet.

Paint the Cabinets

Sand the cabinets to smoothen their texture and polish any impurities. Once it’s ready, paint your cabinets, cabinet doors —you could paint them later, too—, and toe-kick. If you want to make your new island shine into your life, add some polish over the paint, and you’ll be done!

Put Cabinets in Place

Measure where your island will be. Remember that you will need to “divide” the space with the part where the island and dishwasher will be, and the area will people will sit, so you can leave enough space for people to sit comfortably. Then you will first put the toe-kick, using the industrial to attach it to the floor. Once the adhesive has dried, place the cabinets on top, and secure it with some screws.

Prepare and place the countertop

If you haven’t done that yet, you should measure where your sink is going to be and cut your countertop, and support the wooden board accordingly. Use the industrial adhesive to secure it in place, and screw its corners.

Connect Water to Kitchen Island’s Sink and Dishwasher

Important note: If you don’t have the plumbing ready where you are going to install your kitchen island, then you will need to hire a plumber to do this for you.

Put the sink and dishwasher in their places, but don’t install them just yet. You need to connect the water to the kitchen island and add the pipes to connect to them. Test the water and if it runs without any leaks, fully install the sink and dishwasher.

Add The Doors

This is the final step. So be ready to celebrate with a cooking festival after it. If you didn’t paint the doors already, now is the time to do this. Once they are dry, add them to the cabinets. Clean your countertop and voilà! Your kitchen island is your new culinary masterpiece.
