The majority of the coffee-making machines in the market are models with a reservoir that needs to be topped up manually with water. However, some people would prefer to simply plug in their coffee machine and switch it on without the stress of filling it up by hand. If you are one of those people that desire this sort of convenience, then a coffee maker with water line would be an ideal choice for you.

To make it easier for you to find a unit like this, we have reviewed some of the best-plumbed coffee makers. This review covers five of the best coffee makers with water lines across various price points and different features.


BUNN CWFT 15-APSEditor’s Choice

  • Voltage: 110V
  • Capacity (oz.): 101.4
  • Dimensions (in.): 25.2×11.3×27.8
  • Weight (lbs.): 35.91
  • Warranty: 1 year

Other features: digital timer, backup pour-over feature, hot water faucet

The Bunn CWT15-APS coffee maker can brew up to 3.8 gallons of delicious coffee in an hour. It has a tall design that allows it to brew directly into 1.9 to 3 liter insulated airpots which helps to keep your coffee hot and fresh for hours. This unit is quite convenient to use. There’s a programmable digital timer as well as other settings on the front panel which makes it easy to make brew cycle adjustments quite seamlessly.


If you’re looking for a coffee maker that can handle large batches of coffee brewing, the Bunn CWT15-APS is perfect for you. This unit can make between 60 to 120 (8 ounces) cups of coffee in one hour. This makes it perfect for large hotels, break rooms, convenience stores, and catering.

Why did it make our list?

  • Perhaps the best thing about the BUNN CWTF15-APS brewer is how convenient to use it is. It is the perfect “brew-and-go” solution. It is quite easy to transport this coffee maker to meeting rooms, breakfast bars, and pretty much anywhere else it is needed. We love the optional pourover feature as well which is perfect for those who prefer to make their cup of coffee the more traditional way.

What is not ideal about it?

  • This unit features a hot water faucet which makes it quite easy to prepare tea or hot chocolate with the coffee maker. However, the hot water spigot is awkwardly located. It is located on the back wall of the unit underneath the coffee basket. There were also a few complaints from some users about leaks in the machine.

Keurig K155Best Value

  • Voltage: 120V
  • Capacity (oz.): 92.8
  • Dimensions (in.): 14×10.38×13.8
  • Weight (lbs.): 6
  • Warranty: 1 year

Other features: touchscreen interface, 4 brew sizes, adjustable brew temperature, auto on/off feature

The sleek and elegant design Keurig K155 is designed specifically for commercial use. It features a color touch screen with an intuitive touch LCD screen that seamlessly adjusts the temperature and other brew settings. The K155 is a programmable unit with automatic on/off settings, multiple languages, and other advanced settings.

In terms of appearance and functionality, we found the K155 similar to the K150, another popular coffee maker from Keurig. The only remarkable difference between these two options is that the K150 offers an additional brew cup size that the Keurig K155 does not offer. Both units are quite similar as far as other features go.

What stands out?

  • The Keurig K155 is advertised for home and commercial use, and we found that it performs just as advertised. It brews a perfect cup of coffee. But you can also use it to prepare hot cocoa, tea all in under a minute at the touch of a button. The interactive and very intuitive color touch display is an impressive feature. We love the Quiet brew feature, which ensures that the unit works efficiently without distraction or disturbance.

What cons did we manage to find?

  • This unit is advertised as a commercial coffee maker, we would have loved to see a brew strength feature that would make the machine even more desirable for users that would prefer their coffee stronger. It also offers a maximum brew size of 10oz, which is a bit low considering the fact that the identical K150 has a maximum brew size of 12oz.

The Nuova Simonelli Musica is a versatile coffee maker. The Musica is designed to be easy to use with an interface that consists of backlit buttons. It is compact enough to be used at home and also well-built with commercial-grade components that make it suitable for professional usage. We found the heat exchanger functionality of this machine quite effective. It allows you to brew your espresso to a consistent temperature every time. The machine is also programmable for automatic brewing, which makes it perfect for beginners and professionals alike.


There are two versions of the Nuova Simonelli Musica coffee maker. There’s one with a pour-over feature, but this unit is a direct connect machine that can be installed directly into a water source. The Musica is a fully programmable coffee maker, which makes it a more convenient option over an alternative like the Nuova Simonelli Oscar 2, which is manual. They have the same commercial-grade components, although the Musica is the more expensive of both options.

Why is it special?

  • Our first impression of this coffee maker is that it is well-built. It is made from durable components, which makes it likely to last longer compared to other machines, even with consistent everyday usage. We found this machine efficient in terms of functionality as well. The steam pressure is particularly impressive, allowing you to froth your milk quite effectively to your preference.

What are the flaws?

  • While this is a well-built unit, it is larger than most coffee makers for home. Measuring up to 17” in height, don’t expect this machine to see comfortably under low cupboards. Also, it may not work for commercial environments where high volume is required despite having commercial-grade components. At best, you can use it in your mid or small-sized café.

BUNN CWTF 15-3Most Compact

  • Voltage: 120V
  • Capacity (oz.): 960

The first one consists of 3 lower warmers while the other has 2 upper warmers and 1 lower warmer.


The BUNN CWTF 15-3 is ideal for those that want to enjoy the convenience of a direct water line connection to their home or commercial coffee matter. It also features a hot water faucet which works for those who want to use the unit to prepare hot chocolate or tea.

What stands out?

  • There are a lot of things to love about this coffee-making machine. But one of the most impressive is the Splashguard funnel. This deflects hot liquid from burning your hands in case of a splash by deflecting it off.

What cons did we manage to find?

  • The major complaint with this unit is with the installation. The installation process is a bit complex, and the instructions in the manual are not very clear. You may also require some extra parts and components for the installation. Also, the unit isn’t the most attractive plumbed coffee maker you will find around. But if you can look beyond the ugly look, you will find it a well-built and durable coffee maker.

Keurig K2500 Most Popular

  • Voltage: 110V
  • Capacity (oz.): 12
  • Dimensions (in.): 17×14×23
  • Weight (lbs.): 1

It is well built with durable components and a lot of advanced features, including a fully interactive touchscreen that allows you to customize your drink according to your preference.

The Keurig K2500 is one of Keurig’s most popular models in its commercial lineup. This model is an upgrade of the K150P, which was equally quite popular for small businesses and domestic usage because of its portability. The K2500 has a small footprint as well and is reasonably priced for a commercial-grade model with premium features.

What are its best features?

  • Perhaps the most impressive feature of this coffee maker is the high-resolution touchscreen. Not only does this give the machine a more futuristic appearance, but it also allows you to customize your coffee to your preference. The machine is programmable with features like sleep mode, altitude settings, automatic on and off, among others. One of the buttons on this machine is labeled “strong”. Pressing this button adjusts the settings of the coffee to produce a stronger coffee brew automatically. We found this feature quite impressive.

What could be improved?

  • There isn’t much to dislike about this coffee maker. The only slight limitation it has is that it does not have a timer which means you cannot set a wake-time for the machine. The implication is that you have to wait a few minutes for the water to heat up if you’re making the first coffee of the day.

Things to Consider

Plumbed Coffee makers don’t come cheap. You need a sizable budget to get a good quality unit. This means special care has to be taken to ensure that you’re buying a good quality coffee machine and one that is most suitable for your needs. Here are some of the things you need to know if you’re out shopping for a coffee machine with a water line Trusted Source Plumbed in Coffee Machines – Models, Pros and Cons Discussed Plumbed in Coffee Machines – Models, Pros and Cons Discussed to help you decide if this is the right option for you! .

What Is Special about Water Line Coffee Makers

If you’ve ever had a coffee machine run out of water while you’re brewing, it’ll be easier to understand why a coffee maker plumbed directly to the water line is so special. Direct line coffee makers are great for both home and commercial usage because they simplify the process of making a coffee by eliminating the need to constantly refill the reservoir with water.

Choosing the Best Coffee Maker with Water Line

As we said, the selection of plumbed coffee makers on the market is quite small. This is particularly true for coffee makers for home rather than commercial use. The primary reason for this is that a coffee maker connected directly to a water line offers less flexibility than a typical free-standing coffee machine, making the target market quite small.

It should be located in one place, and it’s impossible to move it around a kitchen.

Plumbed Coffee Maker vs. Plumbing Kit.

Many people often prefer to retrofit their coffee maker using a plumbing kit instead of simply buying a plumbed machine as a cost-saving strategy. While this can work, there are a number of pros and cons to this approach. Here are a few tips regarding the benefits and downsides of these two methods.

Possible Advantages

A plumbed coffee machine has several advantages, especially for users within its target market. Perhaps the most obvious benefit of all is the convenience it offers. With the best coffee maker with a water line, you don’t have to refill the water tank. This makes it perfect for making coffee in large homes and offices without bothering about the tank running dry. You may also be able to use the machine to supply hot water for making soups and tea

Ditching the water reservoir is also beneficial in other ways. A unit without a water tank has a lower footprint compared to a tanked machine. Hence, plumbed coffee machines tend to be more compact. It is also good for your health since your coffee will always be made with fresh and clean water instead of stale water that has been in the reservoir for days.

Possible disadvantages

But a plumbed coffee machine isn’t without some limitations. The first is the installation. A coffee maker with a direct water line connection must be installed as close to your waterline as possible. It is also installed in a place which means moving it around after installation is virtually impossible. Installation can also be quite complex, depending on the type of machine you buy. In some cases, you may need to hire a professional for the job.

Another problem with plumped brewers is with the maintenance. The fact that they are connected to your plumbing means they’re likely to be prone to leaks, especially if installation is not properly done. For this same reason, fixing a fault can be a little complicated.

Features to consider

To ensure that you’re making a smart choice as far as buying a coffee maker with a water line is concerned, there are some key considerations to keep in mind. Knowing these things will ensure that you’re buying a good quality unit that will serve your needs for a long time and brew a killer cup of coffee each time.


Like all electronic appliances, the power requirements of your coffee maker vary from one unit to the other. Since this has a major impact on the energy efficiency of your unit, be sure to check and confirm the power specifications. Buying an energy-efficient unit will save you cost in the long run.


If your coffee maker is intended for serving the coffee needs of a large number of people and you don’t want to end up with a long line of coffee drinkers waiting to be served, then a high-capacity unit like the Bunn Airpot would be an ideal choice. It can make several cups of coffee within a short time, which is particularly important for commercial uses.

Item Dimensions and Weight

Best Coffee Makers with Water Line: Always Fresh Cup of Perfect Coffee

Some coffee makers require much more space.

When it comes to choosing a unit with the right dimension and weight, you have to consider how much space you have available on your counter. For instance, machines like the BUNN CWTF15-APS require you to have deeper counter space, while others like the Nuova simply need you to create more elbow room. If you don’t have a lot of space to spare, then you should go for more compact alternatives like the Keurig 2500.


When buying any household appliances, the warranty is always an important consideration. The duration of the warranty cover tends to vary from one unit to the other. Generally, your coffee machine should have a minimum of one-year warranty cover during which the manufacturer takes responsibility for any fault. While this is not a sure sign of quality, a longer warranty duration gives you peace of mind since you are sure that you can easily contact the manufacturer to report any issues. It also helps to find out what’s covered in the warranty and compare this to what other manufacturers are offering for their product.


While the products we have covered in this review are capable and efficient coffee makers suitable for both residential and commercial use, they come in various price ranges. In deciding which of them would be the right choice for you, budget is a major consideration.

Not only do you have to consider the cost of the unit itself, but you also need to factor in the installation costs since plumbed units are best installed professionally. Additionally, some units may require extra components such as water filters. You will have to keep all of these costs in mind when making a buying decision. Price may not be a deal-breaker since most plumbed coffee makers are expensive, but it helps to keep the price in mind when you’re out shopping for a unit.

Other features

A programmable timer saves time and is a lot more convenient.

  • Hot plate: some coffee machines feature a hot plate that is designed to help keep your coffee hot until you are ready to take it.
  • Built-in water filter: coffee is best made with filtered water. However, the design of a coffee machine with a water line means it takes in water directly from the source. Having a mechanism that automatically filters the water for you will be quite beneficial.

Included components

Installing your plumbed coffee maker requires some additional components. While these components are readily available online, some units come with most of the extra components you need already. This saves you cost and stress since you don’t need to shop for additional compatible components separately.


When it comes to purchasing a Built-in coffee maker with a water line, you don’t have a lot of options. First, you have to consider whether you want a unit to serve your domestic usage or commercial needs. This, along with the number of people that will be using the coffee maker, will determine the capacity of the unit to buy. You also need to determine the style of coffee you intend to make as well as your budget which should include both installation and maintenance costs.

Coffee makers with water lines are convenient to use, but they use a fair amount of energy. They also have a higher upfront cost with the cost of installation and additional components, further pushing the price higher. However, they are often preferred for their efficiency. Their benefits really shine when you need a coffee machine that can keep up with a steady supply of coffee, such as in a restaurant, coffee shop, or office. The machine gets to do more since you don’t have to refill the reservoir over and over again, and this sort of makeup for the high upfront costs in the long run.

If you have purchased a good machine with a fairly easy setup, you should be able to handle the installation on your own by following the manufacturer’s instructions. Having all the right accessories also helps. This includes water lines, water filters (optional), and the correct set of fittings for your waterline. These are components you can easily find on Amazon or a local utilities store around you. Alternatively, you can get a pre-assembled plumbing kit for the job. This saves you more time compared to trying to put the system together all on your own.
