Support, kept simple.

The oven ships with a foam top-and-bottom cradle. Lift from underneath, not by the door handle. Two adults recommended for the 24L Steam Oven and the 32L Certainty Oven (they weigh up to 33.5 lb / 15.2 kg).

On a heat-tolerant counter, with at least 4 inches of clearance on all sides and 12 inches above. Not directly under a wall cabinet. Not on a wooden cutting board that doubles as a counter.

Yes — run a 30-minute empty bake at 400°F with the windows open. This burns off the light protective coating every new oven ships with. The smell is normal and goes away by minute 25.

Steam is pure 212°F steam — for vegetables, dim sum, reheating. Steam Bake blends steam with conventional bake heat — for bread, custards. Steam Roast blends steam with higher convection heat — for crispy-skinned chicken, pork belly. Each mode is calibrated for a different humidity-to-heat ratio.

Yes for cycles under 90 minutes with the auto-off timer set. No for cycles over 90 minutes or when away from home. We expect cooks to be in earshot of the oven.

Ounin displays read in °F. The common conversions: 160°C → 325°F, 180°C → 350°F, 200°C → 400°F, 220°C → 425°F. The nearest 25°F step is close enough — and because the cavity actually holds the number you set, the conversion is the only approximation in the bake.

Every 30 cycles, or roughly monthly with daily use. The Clean mode automates this — fill the tank with a 1:3 vinegar-to-water solution and run the cycle. The display reminds you when descaling is due.

Yes — top rack only. Or hand-wash with a non-abrasive sponge in 60 seconds.

Wait until cool. Wipe with a damp microfiber. Stubborn baked-on splatter: baking-soda paste, leave for 10 minutes, wipe off. Avoid abrasive sprays — they fog the glass over time.

Cosmetic damage (scratches, dents from drops), normal wear of consumables (gaskets, lights after 1000+ hours), damage from improper voltage, and damage from accident or unauthorized modification.

No. Checkout works as guest. We store your shipping and email for the order; you can request deletion any time via privacy@ounin.com.

No. Ounin ovens don’t connect to Wi-Fi and don’t send data anywhere. No account, no app, no telemetry. The controls work entirely offline — there is nothing to be online about.

Ounin was founded by a team with two decades of engineering experience designing countertop ovens for leading global kitchen brands. We bring that depth of category expertise directly to home cooks.

Both are in development now. Join the newsletter at the bottom of any page and we’ll email you the moment either one is ready — nothing else in between.
