Keurig K150 vs K155 – Which Is Better for Office?

Looking for the best Keurig coffee maker for your office?

It only takes a bit of research to realize that many Keurig commercial machines look very similar, which tends to leave shoppers confused.

That’s why we’ve lined up two popular but similar models to compare: the Keurig K150 vs K155.

1. Dimensions and Weight

It’s little surprise that such similar models have such similar dimensions.

The difference, minute though it is, can likely be explained by the difference in reservoirs; the K155 is built with an internal reservoir, while the K150 has a removable reservoir.

Both reservoirs have the same water capacity, and are able to brew up to 12 cups before needing to be refilled.

The weight may seem like a drastic difference at first, but we found that the actual shipping weights were similar.

It’s likely that they actually weigh about the same when the K150’s reservoir is attached.

The conclusion

There’s no real difference between the K150 and K155 in weight or dimensions.

2. Reservoir and Plumbing

The biggest difference between these two Keurig models are their water options.

The K150 offers an option for hooking up the machine to a water line, and because of this, has a removable water reservoir.

While the K150 doesn’t come with the parts necessary for the hook-up, they’re easy to find and use.

The K155, in comparison, is not designed for a water line hook-up, though some users say that they’re able to do so anyway.

Attempting to hook this machine up to a water line voids the warranty of the machine.

It also negates the internal water reservoir, meaning the machine will take up the same amount of space for no reason.

To compensate for its internal reservoir, the K155 comes with a quick-drain feature.

This means that it can be transported or stored easily, with no extra parts to worry about and no complicated maneuvering.

The conclusion

Choose the K150 if:

  • You don’t plan on moving your Keurig around very much
  • You have a lot of people in your office (15-30) and a regularly-used kitchen area
  • You want to hook your machine up to a direct water line

Choose the K155 if:

  • You’re going to be moving your Keurig around or storing it from time to time
  • You have a smaller office (less than 15 people), no designated kitchen area or break room, or don’t have many coffee drinkers
  • You don’t want to worry about connecting the machine to a water line

3. Brew Sizes

While this may not be an issue for some people, the K155 does not offer an option to brew in a 12 oz size.

It does have a 6 oz setting, but for those in your office who have or are used to 12 oz mugs, this may pose a problem (1).

The conclusion

Choose the K150 if:

  • Most of the people in your office have a 12 oz coffee mug
  • You use 12+ oz disposable cups

Choose the K155 if:

  • Those in your office don’t mind the lack of a 12 oz feature, or don’t want to over-extract a K-cup (as they are normally designed for 10 oz max)
  • You use 10 oz disposable cups

4. Shared Features and Other Features

Both machines have a touch screen for easy programming, including options for adjustable water temperature and automatic on/off settings. The water temperature range for both machines is about 182-192°F.

The K150 also advertises having three different language settings, making it ideal for multilingual offices, but it is important to note that you cannot turn the options for those languages off, either.

Both models have a dishwasher-safe removable drip tray to accommodate larger mugs and travel mugs. You can see the size of the dispensing area, as well as how much room removing the drip tray gives you, here: 

Both the K150 and the K155 can be used with generic and refillable K-cup pods, unlike more modern iterations.

If people in your office want to be environmentally conscious - or if you simply want to save a bit of money - both of these models are great options.

Be cautious, however, as not all refillable K-cup pods are made the same, and some may not fit the machines.

It’s common that both machines, when bought new from the manufacturer, will smell strangely at first, and that their initial cups will taste strange.

This is a perfectly normal occurrence called off-gassing, and will pass as the machine is used. It’s recommended that a few test cups of just water are brewed before coffee is made to help speed the process along.

If you’re looking to buy the K150, keep in mind that it is only able to be directly purchased with a professional installation.

The K155 can be purchased through authorized retailers; the K150 cannot be purchased individually from Keurig or an authorized retailer. 

This means that Keurig has no obligation to honor a warranty when a K150 is purchased, unless it is done in tandem with a professional installation.


While both models have their advantages and disadvantages, in a comparison of the Keurig K150 vs K155, we have to say that the K150 is preferable in most office settings.

With professional installation settings, a direct water line hookup, different language settings, and a wider variety of cup sizes, the K150 is able to cater to a wide variety of people at a similar cost.
