Let me introduce you to the best coffee maker ever! A Keurig K150 with an auto-refill water tank is one of the best additions I’ve made to my kitchen.
If refilling your Keurig’s water tank after every couple of cups drives you a little crazy, I have good news: the Keurig K150 can be converted into an auto-fill machine that eliminates that annoyance. This is not a sponsored post—I’m simply sharing a kitchen upgrade I love and use every day.
Here’s the situation I had: I drink large cups of coffee—usually about 16 oz—so I run two brew cycles per cup (a 12 oz and a 4 oz). With the standard reservoir, I was refilling the Keurig every two cups, which became a real hassle when we had several guests. The solution was a Keurig K150 outfitted with the auto-fill reservoir and a separate inline water filter.
Important note: the K150 itself does not auto-fill straight out of the box. You replace the standard reservoir with a specially made auto-fill reservoir and add an inline water filter because the auto-fill reservoir does not include the carbon filter found in the regular tank. Once you have those components, the coffee maker can draw water directly from a dedicated supply line.
Installation options
You have two common ways to provide a water source for the K150’s auto-fill reservoir:
- Tap into the refrigerator ice-maker line using a T fitting, which is often the simplest and most straightforward approach if the coffee station is next to your fridge.
- Run a dedicated water line from a nearby water source (for example, from under the sink) to where you want the coffee maker. I chose this route because of space constraints near the refrigerator.
In my kitchen I had a plumber run a small line under the floor from the sink to the cabinet area where I wanted the coffee bar. The water line rises behind the wall ovens and the filter is mounted behind the microwave to keep it out of sight. A discreet hole was drilled in the side of the cabinet so the tubing passes through to the filter, then down through a small opening in the shelf to connect to the back of the Keurig. If you use the fridge line, you’d typically mount the filter behind the refrigerator and place it inline between the ice-maker feed and the coffee maker.
The tubing is visible if you look for it, but it’s unobtrusive and easy to hide if you want a cleaner look. Once installed, the K150 draws water automatically, so you can make back-to-back large cups without worrying about refilling the tank.
Simple styling for a functional coffee bar
After installing the machine I refreshed the coffee bar area with a neutral, everyday look that allows me to add seasonal touches. A tiered tray holds a mix of black and white mugs along with a small sugar bowl and creamer for easy access. A compact pitcher stores an assortment of spoons—both new and vintage—so everything feels coordinated yet practical.
Every time my husband asks if I still love the new coffee maker, my answer is a wholehearted “Yes.” The K150 with the auto-fill setup has made morning coffee easier and more enjoyable for our household and for guests.
