Step 8

You now need to construct the outer shell of your island. Begin by working out where you will attach your end panels to the floor by laying them out next to the cabinets. Make sure the legs of the cabinet won't obstruct the L-shaped brackets.

Step 11

You should then carefully slide the cabinets out from the side and back panels and attach the side and back panels to the floor using L-shaped brackets. Also, use brackets to attach the side panels to the back panel.

Wipe Spillages Quickly

Spillages on the surface of your kitchen island can result in stains or ruin the countertop's material. With this in mind, it's important to always wipe up any spillages as soon as possible.

Use Trivets and Pot Holders

It's best to avoid placing hot items directly onto the surface of your kitchen island. Hot items could affect the surface or stain it so you should use trivets and pot holders to avoid placing hot items right on the counter.

Use Cutting Boards

You should never cut food directly on your kitchen island surface as this could scratch or otherwise damage it. Always use an appropriate cutting board to protect your kitchen island surface.

Clean The Island Regularly

To keep your kitchen island in the best condition possible, you should aim to clean it regularly. A deep clean every one to two weeks should be enough to keep it in tip-top shape. Plus, you should also wipe over it daily after use.

Below is a list of steps that you'll need to take to remove a kitchen island:

  1. Remove any drawers or loose shelves from your kitchen island
