5 Best 42-inch Professional Built-In Refrigerators for 2025

With its larger capacity, the 42-inch professional counter-depth refrigerator is quickly becoming the new standard, surpassing the once-ubiquitous 36-inch models.

However, the selection is more limited, making it even more important to choose the right one.

In this article, you'll learn about the five best brands, their features, and potential drawbacks so you can make an informed decision.

I’ll also introduce an alternative way to buy a 42-inch refrigerator that you may not have considered before.

Choosing the right refrigerator is a big investment, and not all models are built to last.

With over 102 years in the appliance business and hundreds of thousands of service calls, we know which brands are truly reliable.

Unlike influencers, we don’t take payments from manufacturers or use affiliate links. Our recommendations are based on real-world performance, not sponsorships.

Let’s start with a brand-new refrigerator that stands apart from everything else on this list.

5 Best 42-Inch Professional Built-In Refrigerators for 2025

1. Thermador T42BT120NS

Review

Unlike the others on this list, this refrigerator is fully integrated, fitting seamlessly into a 25-inch-deep cabinet.

Its specially designed hinges allow for a flush installation, creating a truly built-in look.

You won’t be able to tell where the cabinet ends and the refrigerator begins.

Plus, you have three options: two stainless steel finishes with different handle styles or a panel-ready model that lets you customize the refrigerator with your own panels.

However, the reduced depth slightly impacts capacity - 23.1 cubic feet compared to Sub-Zero’s 24.7 cubic feet - and comes with a few other drawbacks we’ll cover further down.

Now, let's take a closer look at Thermador’s best features before diving into the potential issues.

Key Features of the Thermador T42BT120NS

Twin Compressors

Twin compressors are standard now for all premium refrigerators but still worth mentioning.

The refrigerator's warmer, moister air and the freezer's colder, drier air are separate, so the freezer defrosts less, leading to better food preservation.

Your food, especially in the freezer, will taste better because you don't have the odor transfer from the refrigerator.

However, the location of the compressor below is important, as you will see in the comparisons section.

Stainless Steel Surface

Stainless steel is the most hygienic surface and is the standard in commercial kitchens because its solid surface prevents germs from proliferating like other surfaces.

Cold is absorbed better in stainless than other finishes, so place your milk and juices next to the stainless.

ThermaFlex Drawer

You can flex the refrigerator or freezer from 0 to 39 degrees on the right-hand top drawer.

You may like the idea of changing the refrigerator to a freezer or just having the ability to keep it as a refrigerator or freezer.

However, being able to convert can also be helpful if you entertain.

You have seven temperature settings, ranging from 0 to 39 degrees, so you have the correct setting for ice cream or pastry.

Ice Drawer

The 42-inch and new 48-inch models also hold two kinds of ice. The top drawer pulls out, so you don't have to bend like in a Sub-Zero bottom drawer.

Diamond Ice

The standard ice on all models is the thicker "Diamond Ice."

It's slower to dissolve than regular ice and better for cocktails and fine liquors, so you taste more of the drink and less water from ice melting.

On the left-hand side, you also have regular ice for colas, beverages, and juices, in addition to cold filtered water.

LCD Screen/HomeConnect App

This refrigerator is loaded with tech, including an LCD screen that displays every setting. This is an upgrade for presentation for any refrigerator.

Home Connect is one of the best-rated apps for any brand. You can control the temperature, get alerts that your door is open, or change your water filter on the app.

Built-In Camera

The four cameras inside the refrigerator allow you to look inside while shopping, so you won’t buy that extra jar of sauce or mayo.

Note: The cameras only work when the doors are closed, so you won’t be recorded late-night snacking in your jammies.

The Thermador T42BT120NS has a stylish design and intriguing features, but let's take a closer look at its potential drawbacks.

Potential Drawbacks of the Thermador T42BT120NS

1. Increased Height Due to Compressor Location

With the compressor below and multiple drawers, this refrigerator starts taller and ends higher than a classic French door model.

From the floor, the height of the refrigerator is 6 feet 11.5 inches (or 83 9/16 inches). That's several inches taller than Luka Dončić, who stands at 6 feet 7 inches (sorry, Luka).

For comparison, let's look at the Sub-Zero 48-inch French door refrigerator.

With the compressor on top and one large freezer drawer, it's only 6 feet to the top.

To be fair, this is true for any integrated refrigerator, not just Thermador.

2. Adjustable Shelving

Thermador is only adjustable in the top parts of the refrigerator:

You can't adjust the shelves below the top four shelves, but you can always fit items below the shelves as well.

The problem is the unexpected bump in the middle of the refrigerator, which limits storage flexibility.

3. Installation and Panel Cost

With tighter tolerances in cabinets, multiple-door integrated refrigerators can be a real pain to install.Seriously.

We have 18 installation teams in Boston who would rather install a double wall oven or cut granite than put panels on a 4 or 6 door refrigerator.

It's a 2-4 job if the cabinet, panels, and floor are perfect - though they rarely are for knowledgeable installers.

For even a skilled installer who has never worked with this type of refrigerator, the installation could take an entire day.

Also, be prepared to spend $1,200 to $2,000 on installation, plus additional costs for cabinets and hardware.

This challenge isn’t unique to Thermador - it applies to any integrated refrigerator with multiple doors, including my Sub-Zero at home.

2. Sub-Zero CL4250UFD/O

Review

Sub-Zero is still American-made and family-owned.

With ten options in a 42-inch refrigerator, Sub-Zero offers more choices than any other brand, including side-by-side and French door styles in both stainless steel and panel-ready models.

Sub-Zero 42-Inch Refrigerators: Side-by-Side vs. French Door Refrigerators

Sub-Zero 42-Inch Side-by-Side Refrigerator: Pros & Cons

I wouldn’t recommend a side-by-side refrigerator in smaller sizes.

However, at 42 inches, it becomes a legitimate option because of its greater usable capacity and lateral spacing.

You also won’t have to bend down as much to access the freezer, unlike with a French door model.

Another advantage is the built-in ice and water dispenser.

It functions well because the ice maker is located in the freezer, not in the refrigerator compartment like in standard French door models.

Sub-Zero 42-Inch French Door Refrigerator: Pros & Cons

French door refrigerators are popular because they offer more refrigerator space overall and wider shelves for easy storage.

Another benefit is that the refrigerator section sits at waist height, so you’re not bending down as often.

The downside? No ice dispenser, less freezer space, and more bending required to access the bottom freezer drawer.

💡Pro Tip: Always bring plates, platters, and glasses to the store before buying to avoid discovering size issues after installation.

Key Features of the Sub-Zero CL4250UFD/O

Sub-Zero refrigerators has the best food preservation system, capacity, and adjustability.

Split Climate Technology

The new split climate technology improves this unit by moving air in multiple places for more even temperatures. Sub-Zero was the original refrigerator with two compressors.

Vacuum Seal

The vacuum seal on the door is designed to keep outside air out, while magnetic crispers keep air in the crisper. This enhances the freshness of your produce.

Ethylene Air Purification System

Sub-Zero's food preservation system scrubs ethylene gas off your fruits and vegetables, which is the gas they emit that causes them to spoil.

This means your produce stays fresher longer. Imagine an avocado lasting two to four weeks in a Sub-Zero refrigerator – that's how effective this system is.

Shelving

The shelves are split and offer various configurations.

Sub-Zero's nanotechnology coating on the shelves prevents spills from spreading, so you won't have to clean up sticky messes months after they happen.

Smart Functionality

You can now control your refrigerator from the Sub-Zero app. Receive push notifications when the door opens or the filter needs to be replaced.

Water and Ice Dispensers

Lastly, Sub-Zero refrigerators are available with internal water, ice, or an ice dispenser. You can choose between a paneled finish or stainless steel.

3. True TR-42SBS-SS-C

True is another family-owned American company similar to Sub-Zero, made in a huge factory outside Missouri.

Known primarily as a commercial manufacturer, if you've ever bought ice cream at your local supermarket, you likely pulled it out of a True freezer.

This unit reflects its commercial styling, and True manufactures almost every component in its factory, including the glass.

Key Features of the True TR-42SBS-SS-C

Hinges

The hinges are designed to handle one million pulls.

Customization

You can customize a True refrigerator with 13 colors and 6 hinge options, allowing for a unique finish. Additionally, their 42-inch model is available with a glass door.

Color customization is a growing trend in appliances, and True offers some eye-catching combinations. Notable options include white with gold accents, green with pewter accents, and blue with copper accents.

Use the arrows on either side of the image below to explore True's customization options:

1 True Pro Refrigeration in Blue and Brass

2 True Professional Refrigeration in White and Brass at Yale Appliance in Hanover

3 True Professional Refrigeration from KBIS 2023 featuring True's new signature color, Bluestone

Temperature Control

True refrigerators feature two compressors and two evaporators. The temperature can be controlled in one-degree increments, similar to a Sub-Zero.

All Stainless

True is solid steel both inside and outside, with no plastic components.

While they don't have an air purifier like Sub-Zero, their stainless-steel interior absorbs cold air better than plastic or painted metal.

Stainless steel also doesn't retain odors, resists spoilage to a certain degree, and is much easier to clean.

Refrigerator Bins

True's crisper bins and shelving are also made of solid glass and steel.

Potential Drawbacks of the True TR-42SBS-SS-C

True is a great alternative to consider, offering a well-built and incredibly solid refrigerator.

However, there are some limitations.

You only have one model option, and True refrigerators are not panel-ready, meaning you can’t customize them to match your cabinetry.

That said, Sub-Zero doesn’t offer the bold color choices that True does, so if you’re looking for a statement piece, True might still be worth considering.

4. Monogram ZISS420DNSS

Then there is Monogram.

The refrigerator is about $5,000 less expensive than the Sub-Zero or True Plus and offers $4,500 in incentives when you buy other Monogram appliances.

Key Features of the Monogram ZISS420DNSS

Advanced Features

The Monogram ZISS420DNSS features a single variable-speed compressor, designed to reduce energy costs and operate more quietly than traditional models.

Inside, sensors monitor usage patterns and adjust the temperature accordingly, helping to maintain optimal cooling efficiency.

Unlike refrigerators that rely on top-down airflow, this model distributes air from each shelf, ensuring even cooling throughout the entire fridge.

Climate Control Tower

The Monogram features a climate control drawer that lets you quick-chill beverages or safely thaw meats with precision.

You can set specific temperatures based on what you're storing, ensuring optimal freshness and convenience.

Crisper Bins

Monogram has also introduced more intuitive controls, including the ability to set a precise temperature in the crisper bin for optimal food preservation.

You can even use the "Express Thaw" function to quickly defrost chicken or "Express Chill" to cool a bottle of white wine just in time for dinner.

Water Dispensers

The ice and water dispenser is the most user-friendly, with different settings for sports bottles and pitchers, and it's made of solid stainless steel.

SmartHQ

Wi-Fi connectivity might not seem like a huge feature for a refrigerator, but Monogram's SmartHQ platform is the most sophisticated in the industry.

Potential Drawback of the Monogram ZISS420DNSS

Monogram is only available in a side-by-side configuration, which may be a limitation for those who prefer a French door or bottom freezer design.

However, it does offer customization options - you can panel it or choose a stainless steel finish.

If you opt for stainless steel, you'll need to order both stainless panels and matching handles separately.

Monogram offers two handle styles: the Statement and the Minimalist, allowing you to tailor the look to your preference.

Despite its limited configuration, Monogram is a more affordable alternative to the higher-priced True and Sub-Zero refrigerators, making it a strong contender for those seeking premium features at a better value.

5. LG Studio SRSXB2622S

LG Studio recently introduced their 25.6 cubic foot stainless steel side-by-side refrigerator.

Key Features of the LG Studio SRSXB2622S

Energy Efficiency & Quiet Operation

The LG Studio refrigerator features a Linear Compressor, designed to operate quietly while also being ENERGY STAR certified, ensuring greater efficiency and lower energy costs.

Interior Design & Storage

Inside, you'll find LED lighting, glass shelves, and an exterior ice and water dispenser for added convenience.

These features provide clear visibility and easy access to frequently used items.

Smart Technology & Connectivity

LG has long been known for its smart home technology, and this refrigerator is no exception.

With Wi-Fi connectivity, you can monitor and adjust the temperature, receive service alerts, and manage settings directly from your smartphone.

Affordability & Value

The LG Studio is a budget-friendly alternative to high-end brands like True and Sub-Zero.

At just under $9,000, it costs nearly half as much as a True refrigerator while still offering premium features.

Potential Drawback of the LG Studio Refrigerator

While the Studio series offers a wider range of affordable packages than Monogram or Sub-Zero Wolf, it doesn’t include all the high-end features of a Sub-Zero or True refrigerator.

However, LG has resolved the compressor issues that affected models between 2014 and 2017, making it a more reliable choice today.

If you're looking for a built-in refrigerator at a lower price point, the LG Studio is a strong contender despite some feature limitations.

Is a 42-Inch Refrigerator Worth It? Pros, Cons, and Key Considerations

Pros of a 42-Inch Refrigerator

✔️ Increased Storage Capacity: Upgrading to a 42-inch model provides 23 to 26 cubic feet of storage, compared to 19 to 22 cubic feet in a 36-inch built-in refrigerator. This can eliminate the need for a secondary fridge, especially for larger households.

✔️ More Usable Freezer Space: Side-by-side models often provide better freezer organization compared to smaller models where freezer space is less accessible.

✔️ Better Brand Selection: In the 36-inch category, the market is flooded with lesser-known brands, making it harder to choose a high-quality model. However, 42-inch refrigerators are typically curated from premium, well-established brands, reducing the risk of a poor investment.

Cons of a 42-Inch Refrigerator

❌ Higher Price Point: A 42-inch refrigerator comes at a significantly higher cost than smaller built-in models. Expect to spend at least $8,500, with some models costing well over $10,000, depending on features and brand.

❌ Shallower Storage Due to Counter-Depth Design: Like all counter-depth and integrated refrigerators, 42-inch models sacrifice some cubic footage in depth compared to standard-depth models.

Flexible 42-Inch Refrigeration Solutions

We don’t sell JennAir, Dacor, or Viking, but they offer some of the best options in terms of price and build quality.

Here’s a trick if you want a 42-inch model from multiple brands.

While most manufacturers have stopped improving or even producing the larger 42-inch refrigerators, they continue to manufacture the smaller integrated types.

Instead of buying a single 42-inch unit, consider purchasing a 24-inch refrigerator and an 18-inch separate freezer.

The advantage is you can place these anywhere.

If you are left-handed, for example, put the refrigerator on the left. If you don't use the freezer often, place it on the outside perimeter of your kitchen.

Integrated refrigerators look great because they are shallower and fit seamlessly within your cabinets. Plus, you have so many different configurations to choose from. 

The disadvantage is you lose some cubic footage because of the shallower depth.
