But both K150 and K150P are compatible with direct-water-line plumbing. In comparison to both models, the K155 doesn’t come with any of these two features.
The next feature differentiating all three models is the cup size availability. The K150 and K150P models enable you to choose from five brew sizes, while the Keurig K155 only from 4.
Before buying the coffee machine for yourself, check out what exactly each model offers and whether these features are what you’ve been looking for.

For your comfort, we have covered all the main features in the comparison chart. But let’s have a deeper look. Hope it will help to choose the right coffee machine especially for you.
All three models share many similarities. All of them are K-cup compatible and are equipped with 90 oz water reservoir.
They all feature an automatic shut off for added ease. When it comes to speed, three coffee makers are actually fast and can prepare a drink in less than 1 minute. Sounds impressive right?
But, they do have some differences. First of all, the difference lies in cup size availability. The Keurig K150 and K150P enable you to choose from five brew sizes, while the Keurig K155 Pro Premier only from 4.
While the Keurig K150p commercial brewing system is pre-assembled for direct water line plumbing, two other coffee machines are not. Maybe the K150 doesn’t feature a plumb kit, but the product is compatible with it.
So, if you want to have a direct-water-line kit you can purchase it separately. Unfortunately, it doesn’t comply with the K155, because it doesn’t feature a plumb kit and isn’t compatible with direct-water-line plumbing.
Keurig K150 Commercial Brewing System Review
When you look at the features the model poses, you understand how well-made this coffee machine is.
Well, it comes in a very handy design and features everything for your comfort. The quality of construction is really high and ensures durable usage. Besides this, it is so easy to install, operate and even clean, making this product a perfect day to day commercial coffee brewer.
It features a full-color LCD touchscreen that is so easy to operate. In case you will have some troubles, just check out the manual. Thanks to touchscreen you can adjust brew temperature, change settings, and choose the preferable cup size out of 5 available options.
Generally talking, the product is great and received many positive customer reviews. But few customers have reported some problems with plastic the taste of a coffee the machine produces.
When testing the product, we personally, didn’t face this problem. But it’s good to know that sometimes it can actually happen. In case of plastic taste just clean the machine with hot water a few times and a smell together with a taste will be gone.
Keurig K155 OfficePro Premier Review
As well as the K150, the Keurig K155 Office Pro Premier is a great machine. It is very well constructed and features many handy characteristics. But it actually differs from two other coffee makers in our review.
This model comes in a little bit smaller and lighter design. It weighs only 6 pounds, while two other – 18 lbs. Even being so lightweight, it features a 90 oz water reservoir.
It is also equipped with a full-color LCD touchscreen ready to help you to choose which cup size you prefer today and change some settings. The machine has an automatic shut off with an energy-saving mode.
The product comes with a removable drip tray for more versatility. The brewing is so fast, so you can prepare a cup of coffee, tea or cappuccino in less than 1 minute.
Plus, the operation is so quiet, making this machine a perfect choice for home and small offices.
If you ask whether we do recommend this product, the question will be definitely yes. We love the range of features it poses. But the best thing is its lightweight design.
Take a look at the absence of plumb kit and compatibility with direct-water-line plumbing. It is important if you don’t want to fill the water reservoir by yourself and find the process really disturbing.
Keurig K150P Brewer w/ Direct-water-line Plumbing – Review
The model is more or less similar to the K150. The K150P coffee maker weights 18 lbs. and measures 14 x 10.5 x 13.6 inches as well as the K150 version. Besides this, these two models feature a full-color LCD touchscreen.
Thanks to this feature you can adjust brew temperature, change settings, and choose the preferable cup size out of available options. Between, they have them 5.
The water reservoir is also large with the capability of 90 oz of water. Plus, it also has a removable drip tray. It ensures versatility and comfort during transportation.
As well as K150, this product brews really fast and prepare your drink in less than 1 minute. The working process is so quiet.
Cool thing, when you consider morning coffee while your partner is sleeping and you don’t want to wake him or her up. Or when you at the office and your colleagues are working hard and you don’t want to disturb them in any way.
When checking out this model, don’t forget that it also features an automatic shut off. It is designed to work in an energy-saving mode.
The difference lies in the machine water supply. The K150P is not only compatible with direct-water-line plumbing, but it is pre-assembled to be directly plumbed in the water line.
With this product, you don’t need to fill the water reservoir by yourself. Plus, you don’t need to spend extra money to purchase a plumb kit separately.
Unbox, assemble, plug in the water line, and press “brew”. Have you ever seen something easier?
In case you have some problems with settings, you can read manual with instructions. For your comfort, it is available in several languages and is very well written.
The last, but not least thing is that Keurig has actually eliminated the problem of plastic taste. We didn’t find any negative feedback related to this issue.
Moreover, we didn’t observe it by ourselves when testing it out. So, if the plastic taste was the only reason why you didn’t want to buy the K150 model, just go for this more advanced version of the same product.
K150 versus K155 – Our VerdictRemember the chart at the very beginning of our review? If yes, then you know that these two products do share many similarities.
First of all, both of them are equipped with a 90 oz water reservoir. It is literally big and is enough to make up to 18 cups of coffee before refilling the reservoir.
Another similarity is a full-color LCD touchscreen. It enables to control such features like brew temperature, on/off settings and cup size.
For more versatility and comfort, both products feature a removable drip tray. It is easy to clean and can be machine washed. Except this, they are designed to work quietly and fast.
You will spend less than 1 minute to prepare your drink, whether it is coffee, cappuccino or maybe green tea. Between, thanks to K-Cup technology, you can also buy mugs specially made for cold drinks.
The variety of them is amazing. You can check out all the available tastes on the original web page. But as always there is something that makes these two products different.
First of all, it is both size and weight. The K150 coffee maker weighs 18 lbs. and measures 14 x 10.5 x 13.6 inches. Compare to it, the K155 Officepro is slightly smaller and a bit wider. It is lightweight and weighs only 6 lbs.
Another difference lies in cup size availability. The 150 model has five brew sizes, but the Keurig K155 only 4.
But the main feature making these two models so different is compatibility with direct-water-line plumbing. As you remember from the chart, the K150 doesn’t feature a plumb kit but is compatible with it.
That’s why in case of K150 you can purchase a direct-water-line kit separately. Unfortunately, it is not possible with K155. Because it does not feature a plumb kit and isn’t compatible with direct-water-line plumbing at all. So, if you do care about direct water supply, simply go for a K150 series.
As coffeeholics, we know how tough it can be to choose the right product among other coffee makers. Especially when you do care about the taste and ease of operation.
But when it comes to Keurig K150 vs K155, we are 100% sure both of them are worth your attention and moreover your money.
