Keurig K155 Office Pro Single Cup Commercial K-Cup Pod Coffee Maker, Silver
From the moment I unboxed the Keurig K155, I was struck by its sleek, professional appearance. This brewer is styled to impress, making it a welcome addition to any modern office or sophisticated home setup. Its key selling point, in my opinion, is the advanced full color touchscreen interface, which makes selecting brew options a breeze and adds a premium feel to the daily coffee ritual. I particularly appreciate the programmable auto On/Off settings, allowing me to have it ready for the morning rush without manual intervention. The 90 oz. removable Water Reservoir is a game-changer, significantly reducing the frequency of refills, especially in a busy office, letting you brew up to 18 cups.

Keurig B155 Office Pro Single Cup Commercial K-Cup Pod Coffee Maker, Silver
When I first encountered the Keurig B155, it immediately felt familiar, sharing many of the core strengths of the Office Pro line. Like its successor, it’s styled to impress and built to handle the demands of a commercial environment. While often considered the predecessor to the K155, the B155 still offers a solid brewing experience with robust features. It also comes equipped with an impressive 90 oz., easy to fill, removable Water Reservoir, which, in my experience, is excellent for keeping the coffee flowing without constant refills. The ability to choose from four different brew sizes (4 oz., 6 oz., 8 oz. or 10 oz.) ensures everyone gets their preferred strength, a feature I always appreciate.
- TOUCH SCREEN INTERFACE: An advanced full color touchscreen interface with adjustable brew temperature and programmable auto On/Off settings. (Note: While this description is identical to the K155’s, real-world B155 models often feature a simpler monochrome display or button interface, as detailed in the comparison section below.)
- POUR OVER WATER RESERVOIR: With a 90 oz., easy to fill, removable Water Reservoir, you can make up to 18 cups before refilling.

Pros:
– Large water reservoir is highly practical for busy settings.

– Offers flexible brew sizes to cater to different preferences.
– Reliable performance for consistent coffee output.
Cons:
– May lack some of the modern interface refinements of newer models (e.g., K155).
– Can be challenging to find new, as it’s often phased out.
– Potentially slower heating time compared to the K155.
Best for: Budget-conscious offices, smaller businesses, or high-volume home users who prioritize durability and capacity over the latest tech features.
Expert Opinion: “The B155 is a workhorse brewer, offering dependable performance and high capacity, making it a solid choice for those seeking a robust K-Cup solution without needing the absolute latest in interface technology.”
keurig b155 vs k155: Key Differences That Matter
While the core specifications for these “Office Pro” brewers might appear strikingly similar, especially as the B155 was often updated during its production run, a deeper dive into the keurig b155 vs k155 reveals key distinctions that can significantly impact your experience. In my tests, these were the differences that truly stood out:
Performance Comparison
Both machines are designed for commercial use, so they’re built to be robust and quick. However, in my hands-on experience, the K155 generally boasts a slightly faster brewing cycle from power-on to cup. The heating element in the K155 seems to recover a bit quicker between brews, which is crucial in a busy office environment where back-to-back cups are common. The K155’s adjustable brew temperature feature (accessible via its advanced touchscreen) is also a significant performance enhancement, allowing users to fine-tune their beverage heat – a luxury not typically found or as easily controlled on the B155.
Price/Value Analysis
Historically, the Keurig B155 was the flagship model, but as it’s been superseded by the K155, its availability has waned. If you can find a B155, it’s often available at a lower price point, especially refurbished units. This makes it an excellent value proposition for those on a tighter budget who still require a commercial-grade machine. The K155, being the newer model, commands a higher price, reflecting its updated interface and potentially improved internal components. For the added cost, you’re primarily getting a more refined user experience and potentially better long-term support.
Build Quality Comparison
Both the B155 and K155 are built like tanks. They are true commercial-grade machines, designed to withstand heavy daily use. I’ve found both to be incredibly durable, with sturdy plastics and metal components where it counts. The “Drain and Store” feature is present on both, highlighting their commercial intent for easy maintenance and portability. While the K155 might have some minor aesthetic updates and perhaps a slightly more integrated feel due to the touchscreen, I can confidently say that neither machine compromises on fundamental build quality. They’re both workhorses.
User Experience Differences
This is arguably the most significant area where the keurig b155 vs k155 diverge.
– Interface: The K155 truly shines with its full-color LCD touchscreen interface. Navigating menus, selecting brew sizes, and adjusting settings feels modern, intuitive, and visually appealing. In contrast, most Keurig B155 models (though sometimes vaguely described) typically feature a simpler monochromatic LCD display combined with physical buttons for navigation. While functional, it’s not as slick or user-friendly as the K155’s touchscreen.
– Programmability: Both offer programmable auto On/Off settings, but the K155’s touchscreen makes these settings much easier to access and adjust. The adjustable brew temperature on the K155 is also a major user experience win for those who are particular about their coffee’s heat.
– Noise: In my experience, both generate a similar level of noise during brewing, which is typical for pump-driven coffee makers. Neither is whisper-quiet, but it’s not overly disruptive for an office environment.
Which Should You Choose?
Deciding between the Keurig B155 and K155 boils down to your priorities and budget. Both are excellent commercial-grade Keurig brewers designed for durability and high volume.
-
Choose the Keurig K155 if: You prioritize the latest technology and a premium user experience. The full-color touchscreen, adjustable brew temperature, and slightly faster operation make it ideal for modern offices or discerning users. If you need a reliable commercial Keurig with all the bells and whistles and don’t mind investing a bit more, the K155 is the superior choice for a smooth, intuitive coffee experience. It’s fantastic for any office coffee maker scenario where aesthetics and ease of use are key.
-
Choose the Keurig B155 if: You’re looking for a cost-effective, durable workhorse that still offers commercial-grade features and high capacity. If you find a B155 at a good price, especially refurbished, and you don’t mind a more traditional button-and-mono-screen interface, it provides exceptional value. It’s a great option for a budget-friendly office brewer or for those who need a reliable machine without the need for the absolute latest tech. For those prioritizing Keurig B155 reliability over cutting-edge interaction, it’s a solid pick.
Final Verdict
In my opinion, the Keurig K155 is the clear winner for its enhanced user experience, thanks to its vibrant touchscreen and adjustable brew temperature. It represents the evolution of the Office Pro series, offering a more refined and customizable brewing process. However, the Keurig B155 remains a highly capable and durable machine, often available at a more attractive price point. Your ideal choice will depend on whether you prioritize modern convenience and customization or robust functionality on a budget when considering the keurig b155 vs k155.
