Single ovens are shorter than double ovens and can be placed neatly under counters. Electric elements are often placed on the top and bottom of the oven to provide zoned heating. This allows for more precise cooking and browning of dishes. You can cook multiple dishes at once, saving time. https://ovensandhobs-uk21163.thezenweb.com/can-a-built-in-single-gas-oven-and-grill-be-installed-in-your-kitchen-69007716
