The Steam Injection System for Home Bakers
Home ovens weren't built for bread. U Steam gives yours the steam it's missing, so you can easily open bake multiple loaves at once with the crust, ear, and oven spring you've been chasing.
Simple multi‑loaf open baking.
Leave the lava rocks, ice cubes, Dutch ovens, and damp towels behind. U Steam replaces every workaround with continuous steam, so each bake rivals what comes out of a professional bakery.

Three simple steps.
U Steam sits on the bottommost oven rack. Compact enough to live in your oven permanently.
Preheat
Heat your oven to 450°F for 45 minutes. U Steam’s thermal mass absorbs heat, ready to generate steam on contact.
Load & Fill
Place your loaves on the built-in bread steel (and optionally on additional racks above). Pour up to 3 cups of water into the reservoir and close the door.
Bake
Water gravity-feeds through the system, vaporizing continuously. Your oven fills with steam for the entire first half of the bake.
Watch the steam in action.
Over a quarter inch of solid aluminum transfers significantly more heat energy than lava rocks or soaked towels. Channels machined into the core spread water into a thin film across the entire surface, vaporizing it continuously.

How many loaves can I bake at once?
While it depends on the exact shape and size you bake, U Steam can typically fit up to 3 boules or batards on the built-in bread steel. You can position another bread steel/stone above U Steam and bake additional loaves above the unit to max out your oven’s capacity. Larger bakes tend to take longer than smaller ones.
Will U Steam work in my oven?
U Steam is made for any standard home oven, gas or electric. Like any bread setup, there’s a learning curve to dial in temperature, timing, and water amount for your oven.
How much water does U Steam need?
U Steam holds up to 3 cups of water and can supply enough steam to make the entire oven cavity humid. We recommend starting by using 2 cups of water in your initial bake and adjusting both water and oven temperature from there.
Will U Steam fit in my oven?
The dimensions of U Steam are 21in long x 15in wide x 2.5in tall — in a standard 30in wide oven, the unit is designed to fit neatly on an oven rack with at least 1 inch of clearance on all sides.
What materials is U Steam made from?
U Steam is made from 100% food grade metals including carbon steel and aluminum.
Where is U Steam available?
U Steam is initially going to be launched in the United States. We hope to serve international customers soon.
