Refrigerator models that place the built-in freezer on the bottom of the appliance are conveniently laid out. Freezer items are usually used less frequently than refrigerator items, so placing the refrigerator compartment at eye-level is ergonomically beneficial.

Refrigerator models with a bottom freezer typically have one, two or three doors for the upper compartment and a single pull-out drawer for the lower.

One major disadvantage of a refrigerator model with a bottom-mounted freezer is that these units are typically more expensive than traditional refrigerator layouts. Sears, which features models for at least 12 brands of refrigerators of all styles, has bottom-freezer models that range in price from $800 to $7,500; in contrast, side-by-side and upper freezer models run from $436 to $8,550.Learn more about Refrigerators & Freezers
