Key takeaways
- Countertop footprint: Most countertop steam ovens are about 14 to 18 inches wide and 16 to 20 inches deep, with extra clearance (often 4 inches) required on the sides and top for venting.
- Capacity: About 1.2 cubic feet fits a 9 by 13 inch pan or a medium chicken, but not a large turkey.
- Water: Countertop models use a removable tank of around 1 to 2 liters. Built-in models may be plumbed.
- Weight: Plan for 40 to 55 pounds, so choose a counter location and avoid lifting it daily.
- Descaling: In hard-water areas, use filtered water and descale every month or two.
The best steam oven for most home cooks in 2026 is the Anova Precision Oven 2.0, the countertop combi steam oven with controllable humidity from 0 to 100 percent and a top temperature around 482 degrees Fahrenheit. Cheaper alternatives include the Nuwave Combi Steam Oven and the Cuisinart steam toaster oven. If you want a built-in unit, expect to spend several times more and need professional installation with a water line or reservoir.

Best overall: Anova Precision Oven 2.0
Steam and Bake and other roundups call it the clear winner for countertop steam. It offers true combi steam with humidity control and sous vide modes, which helps bread develop a crisp crust and keeps reheated meat from drying out. The drawbacks are weight (about 52 pounds), a price near the top of the category and reports that some app features may involve a subscription.
Best value: Nuwave Combi Steam Oven
Cookcraftandcreate rates it the top pick for people who want presets, one-degree temperature control and moisture percentage settings at a lower price. Build quality and support are less proven than Anova’s.
Best multi-function: Breville Combi Wave 3-in-1
This is a microwave with convection and air fry, with steam assistance, not a true steam oven. It suits kitchens that need one appliance to do many jobs but will not give bakery-style crusts.
Best small-household options: Ninja Combi and Cuisinart CSO-300N
These compact units cover steaming vegetables, reheating and baking small batches. Their capacities are limited, and a family of four may need to cook in batches.
Steam vs convection vs microwave: what each does best
| Task | Steam oven | Convection oven | Microwave |
|---|---|---|---|
| Reheating bread | Restores crust and moisture | Dries out | Makes it chewy |
| Salmon fillet | Moist, 8 to 10 min at 190 F | Good at 400 F, riskier | Uneven |
| Roasted vegetables | Good with a dry finish | Excellent | Poor |
| Rice and grains | Good in a perforated pan | Fair | Good |
| Sourdough boules | Excellent oven spring | Needs a Dutch oven | Not suitable |
Times are approximate and depend on thickness, water level and the individual unit.

Cooking examples with steam settings
Steam works at relatively low temperatures, which is why it is gentle on food. Typical starting points drawn from combi oven guidance: vegetables like broccoli take 8 to 12 minutes at 212 F, a 6 ounce salmon fillet takes about 10 to 15 minutes at 200 F, and reheating a bread roll takes around 5 minutes at 300 F with a short burst of steam. For bread, steam during the first 15 minutes of a 450 to 475 F bake lets the dough expand before the crust sets, which is why combi ovens are popular with sourdough bakers.
| Food | Setting | Approx. time |
|---|---|---|
| Broccoli florets | 100% steam, 212 F | 8 to 12 min |
| Salmon fillet | Combi steam, 200 F | 10 to 15 min |
| Dinner rolls (reheat) | 30% steam, 300 F | 5 to 8 min |
| Sourdough loaf | Steam for first 15 min, 460 F | 35 to 45 min |
Times and humidity levels vary by model and load, so use the manufacturer’s recipe guide as the starting point.
Ownership costs and downsides
Steam ovens add routine tasks: filling and emptying the tank, descaling and drying the cavity. Hard water scale can damage heaters, so filtered water helps. A countertop unit can draw close to the limit of a standard 15-amp circuit, so avoid running it on the same outlet as a microwave or kettle. Resale and repair support are weaker than for conventional ovens, which makes warranty length worth checking.
Frequently Asked Questions
What does a steam oven do?
It cooks with moist heat, which preserves moisture in food, reheats leftovers without drying and creates better crusts on bread.
Is a steam oven worth it?
For frequent bakers and anyone who reheats a lot of food, yes. If you mostly roast and microwave, a convection oven may be enough.
Can a steam oven replace a regular oven?
Combi models can roast and bake, but their smaller capacity makes them a complement rather than a full replacement.
Do steam ovens need plumbing?
Countertop units use a water tank. Some built-in models require a water line.
How do you clean a steam oven?
Wipe the cavity after use, empty the tank and run a descaling cycle with citric acid or the manufacturer’s recommended solution.
