How big is a steam oven?#
A built-in steam oven fits a nominal 24 or 30-inch cabinet cutout and stands just 17 to 19 inches tall, while a plug-in countertop version is smaller. The table below covers the built-in and countertop types.
Steam oven dimensions by configuration#
| Configuration | Nominal width (in) | Height (in) | Depth (in) | Best for |
|---|---|---|---|---|
| 24-inch built-in steam oven | 24 | 17–18 | 22–24 | a European-style built-in cavity |
| 30-inch built-in steam oven | 30 | 17–19 | 23–25 | a wider built-in steam cavity |
| Countertop steam oven | 20–24 | 14–17 | 16–20 | a plug-in counter model |

Installation clearances for a steam oven#
- Cutout width: 22–28.5 in in of cabinet cutout a built-in steam oven needs, a little under the nominal width.
- Cutout depth: 22–24 in in of cabinet depth a built-in steam oven cutout needs for the cavity and connections.
- Countertop clearance: 3 in in around a countertop steam oven on the top and back for the steam vent.
- Water source: A steam oven plumbs to a water line or refills a fill reservoir, so plan for one or the other at the cutout.
Will your steam oven fit? Clearances and door swing#
For a built-in steam oven, plan the cabinet cutout and, crucially, the water source. Cut the opening 22 to 28.5 inches wide, under the nominal face width, and 22 to 24 inches deep for the cavity and its plumbing connections. The defining extra is water: the oven either plumbs to a supply line or refills from a removable reservoir, so decide which at the cutout and route a line if you want the hands-off plumbed version. A countertop steam oven skips the cabinet entirely but needs 3 inches of clearance on the top and back for the steam vent so moisture does not damage a cabinet above. Either way, the door swings down or out, so keep the space in front clear. Confirm the cabinet depth and the water plan before ordering.
Safety First — Know the Risks
Gas ovens involve live gas lines — a loose connection creates explosion and carbon monoxide risk. Electric ovens run on 240V circuits. Our techs are licensed and insured — let them handle the risk.

Steam oven sizes by type: 24-inch built-in steam oven, 30-inch built-in steam oven, countertop steam oven#
The three formats range from European built-in to plug-in. The 24-inch built-in steam oven, 17 to 18 inches tall and 22 to 24 deep, is the classic European cavity that tucks into a tall cabinet column. The 30-inch built-in version widens the cavity to 23 to 25 inches deep for a larger kitchen that wants full-width steam cooking. The countertop steam oven, 20 to 24 inches wide and only 14 to 17 tall, is the plug-in model that sits on the counter and refills from a tank — the easiest way to add steam without cabinetry. Choose built-in for a seamless look or countertop for a no-install option.
Steam oven dimensions: common questions#
What cutout does a built-in steam oven need?#
A built-in steam oven needs a cabinet cutout 22 to 28.5 inches wide, under its nominal face width, and 22 to 24 inches deep. Plan a water line or a reservoir refill at the cutout as well.
How wide is a steam oven?#
Built-in steam ovens come in nominal 24 and 30-inch widths, while a countertop model spans 20 to 24 inches. The 24-inch built-in is the most common European size.
How deep is a built-in steam oven?#
A built-in steam oven is 22 to 25 inches deep to house the cavity and its plumbing connections. Confirm the cabinet clears that depth before installation.
Does a steam oven need a water line?#
It needs a water source, but not always plumbing. A plumbed model ties into a supply line for automatic filling, while others refill from a removable reservoir you top off by hand.
How tall is a countertop steam oven?#
A countertop steam oven is 14 to 17 inches tall, low enough to sit on a counter under upper cabinets. Leave 3 inches above and behind for the steam vent.
