How We Chose the Best Undercounter Refrigerator 24 Inch
To choose the best undercounter refrigerator 24 inch, we compared undercounter refrigerators and refrigerator drawers sold on Amazon in the U.S. on width, height, listed capacity, front venting for built-in installation, freezer type, locks, panel-ready doors, outdoor ratings, ADA height and listings such as ENERGY STAR or NSF. We used each listing and the maker’s published details, and we did not run our own lab tests. Capacity and ratings come from the makers, and models change often, so confirm the exact model number before you order.
We checked efficiency claims against ENERGY STAR refrigerator guidance and food-safety temperatures against the FDA’s food storage advice (40°F or colder in the fridge, 0°F in the freezer). Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
How to Choose the Best Undercounter Refrigerator 24 Inch
Width is not the whole story
A “24-inch” unit may be 23.4 to 23.9 inches wide. Check the cabinet opening and side clearance in the manual.
Height options
Standard models are about 34 inches; ADA models are about 32 inches.
Depth and handles
Units are about 22 to 24 inches deep; handles stick out further.
Hinge and swing
Check door swing clearance next to walls or appliances.
Built-in needs front venting
An undercounter refrigerator that will sit between cabinets must vent from the front. Freestanding models vent from the back or sides and can overheat when boxed in.
Measure height, width and depth
Most undercounter units are 24 inches wide and about 34 inches tall for standard counters, or about 32 inches for ADA-height counters. Check depth so the door clears cabinet fronts and handles.
Refrigerator or beverage center
An undercounter refrigerator holds food at safe temperatures with solid shelves and often a crisper. A beverage center focuses on cans and bottles, often with a glass door, and may not get as cold.
Freezer options
Some undercounter units add a small freezer compartment or a freezer drawer. Compartments are often manual defrost and small; true freezer drawers hold frozen food better.
Panel-ready for a seamless kitchen
Panel-ready models accept a custom cabinet front. The panel is sold separately, and installation should follow the maker’s template.
Outdoor ratings matter
Outdoor kitchens need a refrigerator rated for outdoor use, with weather-resistant materials and wider temperature tolerance. Plug outdoor units into a GFCI outlet.
Drawers vs. doors
Refrigerator drawers make items easy to see and reach without bending, but each drawer holds less than a door-style cabinet of the same width.
Locks for shared spaces
Locks are common on commercial and ADA undercounter models. They deter casual access in offices, rentals and dorms.
Energy and noise
Undercounter refrigerators run all day near living spaces. ENERGY STAR models and listed noise figures help compare running costs and comfort.
Plan electrical and clearance
Most units need a dedicated or standard grounded outlet behind or beside the cabinet. Follow the manual’s clearance and leveling instructions.

Tips for Installing an Undercounter Refrigerator
- Use anti-tip brackets if supplied Safety.
- Allow time to settle Wait before plugging in after transport, as the manual says.
- Set 37°F Good starting point.
- Clean the grille Airflow.
