Why Choose Plumbed Coffee Makers?
Coffee machines with built-in water lines are super convenient. Granted, they do cost more than non-plumbable machines but you can’t really put a price-tag on the convenience it brings to you.
Here’s a quick rundown of the incredible benefits of buying a plumbed coffee maker:
- It eliminates the need of filling up the reservoir multiple times a day.
- You won’t make a mess on your countertop, which is difficult to avoid when refilling the reservoir.
- There would be no unused water sitting in the reservoir overnight. Even though it’s common to leave water in the reservoir overnight, it does pose a risk of bacteria growth and mineral buildup that could affect the longevity of your coffee machine.
- With plumbed machines, you can also plumb the drip tray, meaning you won’t have to carry a full tray to the sink anymore to empty it.
- Since the machine will always be connected to the water line, you can make yourself a cuppa in a flash anytime.
- You can connect plumbed coffee makers to inline water filter kit to brew your coffee with only fresh, purified water.
Filtered water not only greatly improves the taste of your brew but also prolongs the lifespan of the coffee maker by preventing scale and mineral buildup.

5 Best Plumbed Coffee Maker Reviews
With no further ado, let’s jump right into our top picks of the plumbed coffee makers currently on the market. If you are in a rush, here’s a quick overview of our top 5 recommendations:
1. Bunn 38700.0009 Axiom DV-3
Boasting an ultra-robust stainless steel frame and 3 cup warmers, the Axiom DV-3 is a product that commands respect. You can operate each warmer base individually and program them to shut off after a predetermined period of time.
Ideal for office and a small bakery that also serves coffee, Axiom DV-3 is littered with useful features. For starters, the plumbed machine automatically adjusts itself to constantly fluctuating water pressure without affecting the brew time or quality.
It offers a host of controls including pulse brew, temperature, and brew-strength settings. In addition to these, it also has a cold brew lock-out which is basically an electronic funnel lock.
It prevents you from removing the brew funnel until the drip-through is complete, ensuring consistent flavor in each pot you brew. Although the machine stops brewing after each pot is filled, you will always have to manually switch off the burner at the end of the day.
In order to keep the burner temperature from overshooting, the machine automatically switches to energy-saving mode when sitting idle for a long period. The addition of a hot water button is a great touch.. Since the burner on until you switch it off manually, you will always have access to hot water for your teas and instant noodles.
2. Keurig K3000SE Brewer
Keurig is just as lucrative a plumbed coffee maker as the K150P. This one, however, is a single-drip machine, and it’s ideal for use both in your home and your office. Here’s what we like about it.
Once you’ve hooked this thing up to your water line, it will keep up a seamless performance. With the ability to brew back-to-back every 60 seconds, this machine ensures that you’ll never run out of coffee.
And as for the mess? The K3000SE take care of that by itself! “How is that possible?” You might be wondering. Well, just ask the automatic K-cup pod ejection mechanism, which detects when the K-cup is empty and gets rid of it with no involvement from you.
So how much coffee can you expect from this thing? Well, that’s up to you. You can choose from 4 different brewing sizes ranging from 4-ounce cups to 10-ounce cups. There’s truly something for everyone.
And the customizability doesn’t stop there. You can adjust the temperature according to your needs, so your coffee is always just as hot, warm, or lukewarm as you personally like it. Furthermore, the bottom tray (used for holding the mug), can be flipped up if you’re using bigger cups.
Finally, just like the K150P, the K300SE also comes with a very impressive LCD touch display. Not only does the touch screen make it easy to adjust the settings according to your needs, but instructions are also provided in 3 different languages: English, French, and Spanish!
3. Keurig K2500 Plumbed Single Serve
Wrapping up this list with yet another Keurig invention that comes with a filter kit. Thanks to the built-in water line, the machine will auto-fill the reservoir with purified water with a quick turn of the valve.
In terms of design, it looks similar to standard coffee makers you will see in offices and small cafes. Owing to the inclusion of a nozzle connection in the plumb unit, you can install it without breaking a sweat and get brewing in no time.
The only real installation work here involves attaching the water filter kit. If you have a working knowledge of plumbing, you won’t need to hire a professional for the job.
The touchscreen interface adds a great flair to the coffee brewing experience. With the help of its sleek and highly responsive interface, you can easily choose your preferred cup size (from 5 options) and brew strength.
Apart from that, you can also program the unit to auto on/off or go to sleep mode at a chosen time. Apart from standard cups, you can also brew directly into your travel coffee mug. Simply remove the drip tray and a 7” tall mug will easily fit under the spout.
Usually, it takes only about a minute to make a cup. But if the machine has been turned off overnight, it will take a couple of extra minutes for the burner to heat up for the first brew.
The machine is about 14” tall and acceptably compact, so rest assured it won’t gobble up premium space on the counter.
4. Brew Express BEC-110BS 10-Cup Countertop Coffee System
The first plumbed coffee maker we’ve selected for your consideration is the BEC-110BS from Brew Express. We particularly appreciate it for its innovative design, dependable performance, and functionality options.
This product offers the best of what any plumbed coffee maker does. Thanks to its self-filling and on-demand hot water supply, you don’t have to sit around and wait for the water to heat up.
Avoiding the mess of adding water to the coffee maker is undoubtedly one of the most appealing benefits of such a product. But even better is the fact that this machine can produce up to 10 cups of coffee. You’re also going to love the cup selector, which is adjustable. This allows you to choose between a half or full carafe, or even just a single mug.
That coffee is stored in a highly heat-resistant, thermal carafe, which has been crafted to perfection. The body of the machine itself is constructed from a combination of durable plastic and metal.
Something else that stands out about this plumbed coffee maker is that it is not actually absolutely necessary to enable a direct water line to use it. If you can’t manage a water line for this machine, you can opt to use a 5-gallon water tank, although, in our opinion, plumbing is the better option.
Overall, this machine is a shining example of a great coffee maker with a direct water line. However, do note that it does not come with a filter. If you want to use one, you will have to install it by yourself.
5. Keurig K150P Commercial Brewer with Direct Water Line Plumb Kit and Filter Kit
Having operated for 30 years now, Keurig is well-versed in the manufacture of high-functioning brewing machines that deliver top-notch coffee every time. The K150P is no different. Let’s see what it has to offer.
Let’s start with the “plumbed” aspect of this plumbed coffee maker. It’s a coffee maker with water line and comes with plumbing kit and filter kit as well.
Why do we say that? Well, in our opinion, a plumbed coffee maker is only as good as its filtration system. Filtered water not only makes for delicious, high-quality coffee but keeps you safe from germs and microbes to be found in unfiltered water.
Next up is the extremely savvy touch-screen interface on this machine. Whether it be setting the brew temperature, enabling the timer, or automating the on/off setting, the touch screen makes it a breeze.
Finally, a word about capacity. The built-in water storage unit holds 90 ounces, allowing you to make cup after cup without worrying about running out. Without a doubt, this is one of the most high-end models out there in terms of plumbed coffee makers. Yes, it’s expensive—but it is that way for a reason!
Buying Guide For Plumbed Coffee Maker
Still not sure about which plumbed coffee maker is the most worth your money? Can’t find the one you want in our reviews? That’s okay. Follow the buying guide below to educate yourself.
One of the most important components of a plumbed coffee maker worth buying is a filter. A high-quality water filter is absolutely necessary if you want good-quality coffee.
Now, many plumbed coffee makers will come already outfitted with a filter, while others might not. Ideally, you should select a coffee maker that has a decent filter. Alternatively, you might have to install one by yourself. This will, however, significantly increase the cost.
When picking out a coffee maker, it’s always important to consider its dimensions. This allows you to ascertain whether it will fit on your kitchen counter.
Thankfully, plumbed coffee makers are relatively smaller compared to non-plumbed units, as they already have a built-in water storage compartment.
That being said, there is significant variation in performance and correlated size, so pick carefully. You can also look out for models that can be wall-mounted or hung underneath cabinet space.
When it comes to home appliances, the quality can vary greatly. However, plumbed coffee makers are usually considered to be a high-end, luxury home appliance. Accordingly, they all tend to be quite well-made.
However, the material used in constructing them can vary greatly. While some may be made from plastic, others might come in brushed metal. As you can imagine, the sturdier the construction, the higher the price tag.
Number of Cups:
One crucial consideration when selecting a coffee maker is the number of cups it can produce in one go. If you have a small household or a small number of family members, a one- or two-cup drip coffee maker should be fine.
If you are buying a plumbed coffee maker for your restaurant, office, or café, you need a bigger drip model. The biggest coffee makers are those that can brew between 10 to 12 cups of coffee.
By its nature, a plumbed coffee maker is a highly automated appliance. However, the best coffee maker with a water line, in our opinion, is the one that allows for greater customizability.
For example, you should be able to choose how full you want the carafe to be or use a timer to program when the coffee-making process should begin. An automatic shut-off feature can also be highly useful for those who are prone to leaving the house in a hurry in the morning.
