Sub-Zero Built-In vs. Integrated Refrigerators (Reviews/Ratings/Prices)

Written by Eddie Jacob | Jul 18, 2017 1:08:00 PM

We wrote this article back in 2012 when Sub-Zero first launched their new integrated refrigerators.

Five years later, Sub-Zero is still selling than their iconic built-in and integrated units. However, they are two very different products, so we will describe the difference and compare both of them.

First, let's talk about the company. 

In 1943, Westye F. Bakke built the first freestanding freezer in the basement of his Madison, Wisconsin home. Bakke was a businessman with a keen sense for trends and a wealth of knowledge about refrigeration.

Just two years later, he established the Sub-Zero Freezer Company in an old, two-car garage (it's funny how most of the appliance companies start that way).

Proprietary Features of Sub-Zero

Sub-Zero's mission has always been keeping food fresher for a longer period of time. Their vacuum seal keeps outside air from infiltrating into the refrigerator. Their two compressors keep the moist refrigerator air away from the dryer air in the freezer, so tastes and odors do not transfer.

The newer features are described in this video, and both of these refrigerators are identical with their feature packages (except the 648PRO).

 
 
 
 
 
 
 
 
 

Thanks for reporting a problem. We'll attach technical data about this session to help us figure out the issue. Which of these best describes the problem?

Any other details or context?

Sub-Zero Built-In Refrigerator / "BI" Series

Sub-Zero offers a slew of options in the “Built-In” category. This type of unit is available in a standard height of 84”, a standard depth of 24” and varying widths ranging from 30” to 48”.

These units vent from the top and the classic stainless steel grill helps provide a professional look to highlight the kitchen. Built-in refrigerators can be installed with custom overlay panels (custom cabinet look), with stainless steel door panels or with stainless frame and a glass door.

A flush inset design installation option also allows the unit to sit flush with surrounding cabinetry. There are 2 different handle options available: Pro and tubular.

Sub-Zero Integrated Series

In late 2012 / early 2013, Sub-Zero launched their new Integrated Refrigeration Series, which replaced their previous, 700 Series. With this release, their entire line of full-size refrigeration now lines up with the industry standard of 84” tall.  

This style unit offers numerous models, tremendous flexibility and can be used anywhere in the home. They merge seamlessly into the décor, with no visible hinges or grilles. Some models offer an upper cabinet refrigerator with freezer storage drawers, or these same style units can be “all refrigerator” or “all freezer”. These units are 84” in height, 24” in depth and available in 30” or 36” in widths.   

There are also all freezer or refrigerator “columns”. These units are also 84” in height, 24” in depth and 18”, 24”, 30” or 36” wide. Other integrated options include the release of their new, 24” fridge and freezer column, model# IC-24C. This unique seamless design, offers a single door, with both a fridge above and freezer below.

Other integrated options include wine preservation columns and under-counter refrigeration drawers.

Typically, integrated units are set up with custom overlay panels. Stainless steel panels are also available but must be purchased separately. Unlike the built-in units, these units vent on the bottom.

Here is a list of different Integrated Model Styles and Prices:

Which Sub-Zero is Better: The “Built-In” or the “Integrated” Series?

First of all, the features are the same, so you are comparing aesthetics, prices, and total cubic footage. The integrated is more expensive but offers less cubic footage for less depth (21 vs. 19.7).

From an aesthetic point of view, you are comparing this. 

The integrated looks better in cabinets because it is designed to fit within the cabinet itself. Have a look in actual kitchens.

Integrated, with Custom Panels

Built-In, with Custom Panels

In stainless, it is less obvious. You may like the built-in better for the industrial look. You also have the more popular French door option in built-in only. You can also buy the built-in with a glass door as well.

Integrated, Stainless Steel

Built-In, Stainless Steel

As I mentioned, the integrated is more popular due to the current trend of covering the refrigerator with a panel. For a stainless kitchen, the built-in may be better, but in the end it depends on your personal tastes.
