How to Choose Your Ideal Sub-Zero Refrigerator

After reviewing the top Sub-Zero refrigerator models, how do you select the perfect one for your kitchen and lifestyle? Here are the key factors savvy shoppers consider when investing in one of these luxury appliances:

Consider the Dimensions

Sub-Zero refrigerators come in width options from 30 up to massive 48 inches. Measure your existing kitchen space or renovation plans to find the perfect fit. Also factor in extra space needed for doors to fully open.

Freestanding or Built-In

Freestanding units like the PRO-36R are movable and don’t require custom cabinetry. Built-ins like the BI-36U/S integrate completely for a unified kitchen look.

Refrigerator, Freezer, or Combination

Think about your family’s chilled storage needs. Combinations like the BI-42S/O provide the most versatility in one unit. Wine cellar units like the IC-36R optimize conditions for sensitive contents.

Finish and Paneling

Sub-Zero’s sleek stainless steel finish looks brilliant but built-ins can also be customized with glass or wood panels to match cabinetry.

Specialized Features

Do you want advanced wine preservation? Multimode freezer temperatures? Consider which high end features best suit your kitchen and contents.

Budget

Sub-Zero refrigerators range from a few thousand for smaller units up to $15,000 or more for large customized models. Set a budget before falling in love with a luxury upgrade.

Professional Advice

Speaking to an authorized Sub-Zero dealer is invaluable for finding your perfect model, dimensions, finish and features.

Test for Fit

Don’t forget to measure doorways, halls, stairways and elevators to ensure your chosen refrigerator can be delivered and installed properly.
