Overview
The ZLINE WADBZ-30-KCB is a 30 inch built-in double wall oven finished in black stainless steel and paired with champagne bronze Helix handles. Both 5.0 cu ft cavities run true convection, and the upper oven adds an air fry mode with a removable basket.
Black stainless is ZLINE's darker finish option, offering a break from standard steel while champagne bronze hardware on the two Helix handles adds a warm metal contrast. The handles are knurled for grip and carry a fingerprint-resistant coating, a detail aimed at kitchens where the handle sees daily use.
- Two 5.0 cu ft true convection ovens
- Air fry mode in the upper oven with basket
- Black stainless steel body with champagne bronze Helix handles
- Touchscreen control panel with child lock
Who it's for
Fits kitchen remodels calling for a built-in double oven with a dark, non-standard steel finish and warm-toned hardware. Not the pick if you want a lighter satin or classic stainless look.

- Air fry mode with removable basket, no separate appliance needed
- Two 5.0 cu ft ovens for cooking two dishes at once
- Fingerprint-resistant Helix handles
- Convection and air fry modes are specific to the upper oven per the listed specs

- Self-clean cycle type is not detailed beyond the name
Performance notes
Convection bake, roast and broil modes run in the upper oven, with two cooling fans across the unit to manage heat during long or back-to-back cooking. The touchscreen panel controls both ovens, and a child lock on the panel blocks unintended input.
