  • Sabbath mode keeps the oven usable on the Sabbath
  • Cool-to-touch handles and stainless finish
Cons
  • Needs a dedicated 240-volt, 4,800-watt circuit

Questions and answers

Is the COSMO COS-30EDWC worth it?
It is one of the lower-priced 30-inch double wall ovens with convection and self-cleaning. If you need two ovens and a 240-volt hookup is already in place, it covers the basics at $1,966.74 at Amazon as of November 5, 2026.
What are the cutout dimensions?
The unit measures 29.88 inches wide, 51.19 inches tall and 23.5 inches deep. Plan the cabinet cutout around those figures and confirm clearance with COSMO's installation guide before ordering.
Does it need a special electrical circuit?
Yes. It runs on 240 volts at 4,800 watts, so it needs a dedicated 240-volt circuit sized for that load. A standard 120-volt outlet will not work.
How does the upper oven differ from the lower one?
The upper cavity is the convection oven with bake and broil; the lower oven is a secondary cavity with its own interior dimensions. Check which modes each cavity supports before relying on both for convection.
When is the price lowest?
Wall ovens tend to drop during major appliance sales around holidays and during kitchen-remodel season. Track the price history here and compare the 5 stores listing it new.
Where is the COSMO COS-30EDWC cheapest?
At Amazon, for $1,966.74, as of our latest check.
Where can I buy the COSMO COS-30EDWC?
5 stores we checked sell it, including Home Depot, Morealis, LuxHomeLifestyle, eBay, Amazon.
