A double wall oven stacks two separate ovens in a single 30-inch opening, so you can bake at two temperatures at once or keep one oven free for a side dish. Look at total capacity, how each oven heats, and whether the controls and cleaning features suit how you cook.
The six ovens below are 30-inch electric built-in models from different makers. Capacity, wattage, features and size come from each product’s listing page and are the makers’ own. Several listings contain figures that do not agree with each other, and we point those out. We have not used these ovens ourselves.

The 6 Best Double Wall Ovens
1. Samsung NV51K6650DG 30 Inch Smart Double Wall Oven
A black stainless steel 30-inch double oven with dual convection, a steam cook feature, Wi-Fi control through the SmartThings app and voice assistant support. The maker describes a large 5.1 cubic foot capacity; the listing does not say whether that is per oven or combined, so check the manual. It lists 240 volts, a 1 year parts and labor warranty and a fingerprint resistant finish.
Suits: a connected kitchen. Strengths: steam cook, Wi-Fi and dual convection. Weaknesses: an unclear capacity figure. Skip it if you need a confirmed total capacity.

Care and Setup
- Check the cabinet cutout height, width and depth against the listing, then confirm with the installation manual.
- A 240 volt circuit is needed; have an electrician confirm the wiring.
- Follow the maker’s instructions for self-clean cycles and remove items the manual says to take out.
- Use the lower oven for side dishes while the upper oven holds the main.
Mistakes to Avoid
- Reading a per-oven capacity as a total, or the reverse.
- Ordering without measuring the cutout height.
- Forgetting the electrical requirements.
- Assuming both ovens have the same features.
Double Wall Oven FAQ
Do both ovens use convection?
Not always. The Cosmo lists convection in the top oven and standard bake below, so read each listing.
Is a double wall oven the same as a double oven range?
No. A wall oven is built into cabinetry and has no cooktop, while a range includes burners or a cooktop.
The Short Version
For steam cook and app control, the Samsung. For a clear 5 plus 5 split, the GE. For a French door, the Cafe. For an air fry mode and probe, the Rangaire. For knob controls, the Forno Asti. For a convection top oven, the Cosmo Haven.
