Quick Review For Top 10 Coffee Maker With Water Line
Ninja 12-Cup Programmable Coffee Brewer, 2 Brew Styles, Adjustable Warm Plate, 60oz Water Reservoir, Delay Brew – Black/Stainless Steel
The Ninja 12-Cup Programmable Coffee Brewer in Black/Stainless Steel is designed to be the last coffee maker you’ll need, adapting to your daily routine rather than the other way around. Its core philosophy is simple: give you control over every aspect of your brew, from flavor to timing. It starts with choice. The 2 Brew Styles let you decide between a Classic brew for a well-rounded cup or a Rich brew for a more intense, full-bodied flavor.
Both are engineered to be flavorful and never bitter, thanks to the integrated Hotter Brewing Technology. This system manages water temperature and saturation carefully, ensuring even extraction for a consistently great pot. Whether your making a full 12-cup carafe for a group or just a few cups for yourself, the quality holds up. The dedicated Small Batch Function is key here—it adjusts the brewing parameters so that a 1 to 4 cup brew is just as robust and never watered-down.
Your morning is made easier with smart programmability. The 24-hour Delay Brew function means you can set it the night before and wake to the aroma of freshly brewed coffee. For those who are up earlier than the pot finishes, the Mid-Brew Pause feature lets you sneak a cup without disrupting the cycle. Once your coffee is ready, the Adjustable Warming Plate has multiple settings to keep it at your preferred temperature for up to four hours, preserving flavor without scorching.
Hamilton Beach 2-Way Programmable Coffee Maker, 12 Cup Glass Carafe And Single Serve Coffee Maker, Black with Stainless Steel Accents, 49980RG
The Hamilton Beach 2-Way Programmable Coffee Maker, 49980RG, is designed to fit how you actually drink coffee. Some mornings you need just one quick cup to go, and other times you’re brewing a full pot for the whole household. This model gives you both options in one machine, so you don’t have to choose or clutter your counter with two separate appliances.
On one side, you have a dedicated single-serve brewer.
It comes with a reusable mesh scoop—you just add your own ground coffee, place the scoop in the holder, and brew directly into your cup or travel mug, up to 14 ounces. It’s a straightforward system that doesn’t rely on plastic pods. This means you can buy any bag of ground coffee you like, which often costs less per cup and creates far less waste than single-use pods. The flavor can be fresher too, since your using your chosen coffee grounds.
Just a note, this side is not made for K-Cup pods.
The other side is a classic 12-cup programmable coffee maker with a glass carafe. You can set it up the night before to have a full pot ready when you wake up. It also has brew strength settings, so you can choose a regular or bold flavor for the pot. A handy feature here is the AutoPause & Pour function.

This flexibility means no one has to compromise on their favorite way to enjoy coffee. The design is genuinely space-smart. At first glance, it looks like a compact single-serve brewer. The 12-cup glass carafe is cleverly tucked on the side, keeping the overall footprint slim.
The 60 oz. removable water reservoir adds to the convenience—it can be positioned on the back or the side of the machine to best fit your kitchen layout. This large capacity means you can brew a full carafe or up to seven single cups without needing a refill. Programmability is straightforward.

Coffee Maker With Water Line Buying Guide
Imagine never having to fill a water reservoir again. A coffee maker with water line connects directly to your home’s plumbing, giving you an endless supply of water for brewing. It’s a game-changer for busy households or offices where making pot after pot is the norm. The key is finding one that fits your space, your coffee habits, and your budget.
Plumbing Connection and Installation
This is the big one. You’ll need access to a cold water line, typically under your sink. Some models include a simple tee-fitting for easy DIY setup, while others might require a professional plumber. Check what’s in the box and measure the distance from your machine to the water source. Not every kitchen layout is suitable, so plan this first.
Brewing Capacity and Speed
How much coffee do you actually drink? These brewers often excel at volume. Look at the carafe size—some hold 12 cups, others go much larger. If you entertain often or have a big family, a high-capacity model makes sense. Also, consider brew time. A faster machine is a real bonus when you need a lot of coffee ready quickly in the morning.
Programmability and Convenience Features
Since you’re removing the daily task of adding water, you can automate almost everything. Look for programmable timers, strength control, and auto-pause functions. A built-in grinder is a fantastic feature for ultimate freshness. Also, a thermal carafe instead of a glass one on a hot plate keeps coffee tasting better for longer without burning it.
Maintenance and Filter Systems
Direct plumbing means your machine uses whatever water you have. A good built-in water filter is essential to protect the brewer from scale and improve your coffee’s taste. Remeber to check the filter replacement schedule. Also, ensure parts like the brew basket and carafe are easy to remove and clean, as regular descaling will still be needed.
