Checklist : Keeping a checklist can be very helpful when it comes to having lots and lots of things to order and purchase. It will allow you to keep track of what has been purchased and what are the outstanding items that need to be ordered. Always keep the checklist handy as you will never know when you will need it for reference when you are out at the mall.
Precise Measurement : Precise measurement of the overall footprint of your kitchen isle is crucial as the material that you are going to order or buy will solely depend on these set of measurements. Remember to cater enough room for people walking in and out of the kitchen. Measurement for each of the core components of the island is another part of the game that need to be perfect especially for those structures that will need to be integrated together to form the main framework of the kitchen island. Make it a point to record the measurement on a notepad or digital gadget, never write it down on a piece of paper that may get misplaced.
Allow adequate countertop space on both sides (left and right) of the kitchen island if a sink or cooktop will be used. Include at least 15 inches of countertop space on each side, and if your kitchen is large enough, allow even more space. You can never have too much countertop space in a kitchen. Also, rounded countertop corners help protect everyone from bad bruises -- this is true about all kitchen countertop corners.
What can we expect to pay for an island during a remodel? This one is too hard to answer because there are simply too many choices. A "ready to install" stock island you can purchase in a home store with connections for drainage and power can run about $800. A custom concrete countertop island with sink, cooktop, and wine refrigerator can easily eclipse $10,000.
