A:Answer Hi Kaka- Built-in capable requires standard countertop height for under counter installation. The unit is 33"H. The minimum cutout height is 33 1/2". See page 10 of the Installation Instructions for details: http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-60734-2.pdf - Also, the unit can be installed (built-in) with 0" air clearance on sides, top and back so there are no heat issues.
