Three checks before you choose

  • Where will it sit? Measure counter width and depth, then allow the clearance listed in the model’s manual.
  • What will you cook? Check a favorite dish or pan against the usable interior and included accessories. Capacity alone does not tell you what will fit.
  • Which modes matter? All three include Steam, Steam Bake and Steam Roast; the additional modes and controls differ.

Dimensions above are the appliance dimensions listed on the product pages, in inches. Check the current product page and user manual before planning counter clearance or choosing cookware.

Choose 12.7 QT when counter space matters most

The 12.7 QT Steam Combi Oven has the smallest cavity and outer footprint in this group. Its eight functions cover Steam, Steam Bake, Steam Roast, Air Fry, Bake, Dried, Ferment and Clean. Clean is a care function, not a cooking program.

At 13.0 × 12.6 × 14.0 inches, it is the first model to measure if counter space is tight. The manual calls for at least four inches of clearance on all sides, so plan for ventilation as well as the oven itself.

Choose 19 QT for Sous Vide and Dual Cook

The 19 QT Steam Oven adds Sous Vide and Dual Cook to Steam, Steam Bake, Steam Roast and Air Fry. In Dual Cook, the oven broils above while steaming below in the same cycle—an option to consider if you like planning two parts of a meal together.

Its listed external dimensions are 16.0 × 14.0 × 15.4 inches. Check the manual’s clearance requirements and compare your usual cookware with the usable interior before choosing.

Choose 25.4 QT for the largest cavity

The 25.4 QT Steam Oven offers the largest cavity in this group, with modes for steaming, baking, roasting and air frying. Compare the full mode list with the meals you make most often.

The body measures 16.9 × 17.3 × 14.8 inches. If you are choosing it for a particular roast or pan, check the food and cookware dimensions against the usable interior and the supplied accessories; cavity volume alone cannot confirm a fit.

A practical way to decide: Measure the counter and required clearance first. Then check your favorite pan against the usable interior and compare the modes you would reach for most. Choose by fit and routine, not the liter number alone.
