How big is an undercounter ice maker?#
An undercounter ice maker installs in a cabinet cutout 34 to 35 inches tall and 15 to 24 inches wide, matching a standard counter height. The table below covers the 15-inch, 24-inch, and outdoor-rated configurations with their exact dimensions.

| Configuration | Width (in) | Height (in) | Depth (in) | Best for |

Installation clearances for an undercounter ice maker#
- Cutout height: 34–35 in in of cabinet cutout height an undercounter ice maker needs under a standard counter.
- Cutout width: 15–24 in in of cabinet gap an undercounter ice maker slots into, matched to the nominal width.
- Front-vent clearance: An undercounter ice maker draws air and exhausts through the front grille, so no rear or side air gap is required.
Will your undercounter ice maker fit? Clearances and door swing#
Sizing an undercounter ice maker is about the cabinet cutout: plan a cutout 34 to 35 inches tall so the unit aligns with the counter, and 15 to 24 inches wide to match the model. Depth is a consistent 24 inches, with outdoor-rated units a touch deeper at 24 to 25 inches. Leave clearance at the back for the water supply line and, on drained models, the drain, and confirm the unit gets airflow — front-venting models can sit fully enclosed, which matters in a tight cabinet. Measure the cutout height, width, and depth precisely before ordering, since the unit rests on the surrounding counter.

Undercounter ice maker sizes by type: built-in 15-inch, built-in 24-inch, outdoor-rated 15-inch#
The three undercounter styles fit different locations. A 15-inch built-in, 34 to 35 inches tall and 24 inches deep, is the standard indoor choice for a home bar or kitchen, needing only a narrow cabinet gap. A 24-inch built-in, the same 34-inch height and 24-inch depth but wider, produces more ice for frequent entertaining. An outdoor-rated 15-inch model, 34 inches tall and slightly deeper at 24 to 25 inches, uses sealed, weather-resistant components for a patio kitchen or bar. All three fit a 34-to-35-inch cutout height and rest on the counter.
