A:AnswerHi JJ- Thanks for viewing GE! The Cutout Dimensions are approximately 28-1/2"W x 19-5/8"D. Countertop modifications would be required. You can view the Quick Specs at the following link: http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=330327_jgp333det_c2.pdf - Optional JXTR32B Filler Kit (sold separately) will reduce any 30" cooktop cutout as large as 29-13/16" wide by 20-7/16" deep to what will be the "standard cutout" size for most current 30" models. We suggest to view the Installation Instructions for details: https://www.myapstore.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=31-10615_adapter%20ring%20kit.pdf - Keep in touch!

A:AnswerHello - this is Nancy at GE Appliances and I am happy to help you. We regret we do not have a cooktop that requires a countertop cutout of 18-1/2" x 29". Most of our new cooktops require a countertop cutout of 28-1/2" wide x 19-5/8" deep. If you are replacing a GE cooktop with another GE cooktop, then we recommend checking with your dealer to see if you qualify for the GE Fits! Guarantee! I hope this helps! Thanks for checking with us!
