The average freestanding stovetop or combo oven weighs anything between 120 to 330 pounds, while a wall-mounted oven generally weighs between 75 to 130 pounds. At around $0.10 per pound, depending on the quality of the stainless steel in question, you're looking at approximately $12 to $33 at the least for scrapped freestanding ovens, and $7.50 to $13 for wall mounted ovens.
