Our take on the Cosmo 24 in. Electric Built-in Wall Oven with 2.5 cu. ft. Capacity C51EIX

The Cosmo C51EIX is a 24-inch built-in single electric wall oven with 2.5 cu. ft. of space, eight cooking functions and Turbo True European convection. It runs on 240V at 3250W and has a triple-layer cool-to-touch door, a cavity cooling system and an auto safety shut-off. Push-button and pop-out knob controls keep it simple, and there is no app or smart-home control. At $599.99 at Home Depot as of November 7, 2026, it sits at the low end of its recent range, with two stores pricing it new.

Questions and answers

Is $599.99 a good price for the Cosmo C51EIX?
It is the best new price found as of November 7, 2026, at Home Depot, and only two stores list it new. That puts it near the bottom of its recent range, so it is a fair buy at this figure.
Will it fit my existing 24-inch wall oven cutout?
It is built for a 24-inch wall opening and measures 24 in. wide, 23.4 in. high and 22.6 in. deep. Check your cutout height and depth against those figures before ordering.
Does it need a special electrical circuit?
Yes. It runs on 240V at 3250W and is hardwired, not plugged into a standard outlet. Confirm you have a 240V circuit rated for the oven before installation.
Does it have true convection?
Yes. Cosmo calls it Turbo True European Convection, with a fan and rear element for even heat. It is one of eight functions, alongside conventional, broil and defrost modes.
Is there a self-clean cycle?
No self-clean cycle is listed. The interior has an enamel coating meant for easy wipe-down cleaning.
Can I control it from my phone?
No. The C51EIX has no app or smart-home control. Everything runs from the push buttons and pop-out knobs on the front.
