Michelle, Hi there, My name is Michelle and I am a kitchen designer for the Home Depot. If you go into any of our stores you can get info on how to replace your counter tops, as well as cost information. you can purchase the tops already cut to your dementions or you can get the slabs in the store to cut yourself. the project is actually one of the more simple kitchen renovation. If you have a corner the mitre cut is the hardest thing about the job and for the money I would have the tops precut, this is about $12.50 per linear foot (cost may vary by market) for standard waterfall edge tops. Good luck. vary
